Rein Shroud

Rein Shroud (レイン・シュラウド) is the main protagonist of Beast Tamer series. He is a beast tamer who was kicked out of the Hero's Party because of his incapability of battling by himself. Not having remorse for leaving the party, Rein decided to become an adventurer and explore the world without any restrictions. On his registration test, he met Kanade, a member of Cat Tribe, which is one of the strongest races.

Appearance
Rein is a tall, well-built, and cool-looking man. He has messy, ash grey hair along a black mesh with bangs in front of his forehead and blue (green in manga and anime) eyes. In light novels, he wears a half black and half grey shirt with folded sleeves, a brown belt around his waist, which has a pouch for his ammunition or certain items, light black pants with the grey blazer tied around his waist and a pair of leather boots. He is equipped with a body leather armor on his left side and full leather armor on his legs whereas in the manga, he wears a white shirt and light green pants. He wears Narukami on his right hand which allows him to set ambushes that make it a standard weapon for Rein as a beast tamer. After the incident with Horizon's Lord, he keeps Kamui on his lower back.

He's been described as being a cute and handsome man by his Ultimate Contractuals.

Personality
As the sole survivor of his village, he is careful not to get carried away and become arrogant. As a result, he is extremely self-aware and humble, but that leads him to become too good of a person, as he was unable to seek through motives of his former party members. He is kind, helping his friends and protecting his contractuals whenever needed. Even being kicked out of the party, he never stops aspiring to dream of becoming an adventurer, which shows his positive nature.

He is extremely tolerant even if someone has bad-mouthed him. However, he displays aggression and ruthlessness toward anyone threatening his friends. He is also prepared to risk his life for the sake of other people, such as when he saves a stranger from a group of thugs. According to Tania, his easily trusting nature can lead to trouble, but it's a good trait since it makes many people help out. While he has no problem going head-to-head with his enemies when he can, in situations where the stakes are high, he has no qualms fighting dirty, such as using moths with paralyzing scales to cripple guards at a warehouse holding hostages, or sending swarms of poisonous insects at powerful demon generals. When he sets his mind to a goal, he puts his all towards completing it. He will put himself on the line to protect others, even knowing it won't be in his own interest to do so and even if he doesn't actually want to do it. This is demonstrated when Arios tries to recruit him for help with the Lost Forest despite having kicked him out of their party. Rein clearly doesn't want anything to do with them, but Arios's party is trying to stop a threat to the entire world, so Rein agrees. Rein offers to help Sora within the Lost Forest itself even though she's already given them what they came for, and they have no other reason to remain. Tania tends to chide him as being "too good of a person" because of this, while Kanade realizes it's due to Rein's village being destroyed in his childhood. He doesn't want to see someone else suffer that same kind of tragedy. This also caused him to earn the affection of his contractuals and several others.

Whenever possible, he doesn't just sit back and passively wait for trouble to come to him. He will preemptively target and eliminate any possible evil-doer the first chance he gets. Case in point, in episode 2, he rescues a merchant from some bandits and the merchant points out the bandit gang is likely to come for vengeance. In response, he tracks down their headquarters and completely crushes the gang. Then when Edgar Fromage comes at him in town, corrupt knights in tow, he doesn't just fight off the knights and rescue the hostages, he systematically takes Edgar's power structure apart and goes after him, raiding his dungeons to free his victims and gain as many allies as possible. As a beast tamer, he has already shown to defy the logic of the class. Rein himself seems oblivious to his own increased aptitude until Kanade points it out, and what's known of his past suggests his now-destroyed hometown was home to Beast Tamers of similar ability to his own.

Background
Rein was born in a village where special Beast Tamers gather. His parents were beast tamers. Ever since childhood, he has loved playing with animals and birds, so he decided to become a beast tamer like his parents.

When he was twelve years old, his parents said they were busy and couldn't watch him practice. Nevertheless, Rein practiced thoroughly, only comes to find out that monsters attacked his village and Rein's parents died in the action, leaving Rein as the sole survivor. Luckily, adventurers noticed him and started working in an adventurer's acquaintance's inn. And many years later, he met the Hero's Party and decided to join the party to prevent a massacre happened like in his village.

As time passed, the hero and his members started being crueler. overly arrogant and ultimately kicked him out of the party, beginning to accuse him of being worthless. Rein then decided to become an adventurer. He took the registration test on killing 10 goblins. He then finds someone's scream, running worriedly and only to find that a Killer Tiger cornering "someone". He decides to act on his knife to attack it, but its skin is so hard that the knife shatters. Then, he was saved by Kanade, who came from Cat Spirit Tribe. Upon befriending him, Kanade asks Rein to tame her, and Rein does so, much to his astonishment and surprise. Since then, he has become incredible strong because he gains traits of the ultimate species, he formed contracts with. Even with his newfound power, he remains humble, and grateful to the numerous girls he contracts with. He literally becomes the hero he wishes he could be, having the strength to actual combat dangerous monsters, people and demons. The first people in the Hero Party to realize that Rein is actually a rarity among beast tamers, are ironically the girls, while the men remain oblivious to Rein's newfound strength.

Beast Tamer Volume 1
Rein Shroud gets called out by his party members. Arios tells Rein he is fired from the party which made Rein very shocked. Rein asks for the reason and Leanne harshly said it was done because he is useless. At this, other members start mocking him and when he tries to talk Arios tells him he shouldn't since it'll be pathetic at this point. So, Rein leaves the party along with returning the gear.

In the city on the horizon, Rein starts thinking about what he should do now. While he was still thinking, some children came to him and asked whether he completed the job or not. Then they asked him to do the usual thing and Rein happily accepts to do so. Rein sees an eagle flying and makes a temporary contract with it. He orders the eagle to say hello to the children which made the children very happy and decided to let the eagle go. The children tell Rein they'll become beast tamer just like him rather than being a hero. When Rein inquires about this, they say the other party members always look annoying but Rein is different and always plays with them. At this, he remembers the people's annoying behavior whenever he talks about the hero party. Thinking for a while, he decides to become an adventurer.

At the Adventurers Guild, Rein gives his name for registration as an adventurer. He asks the guild receptionist, Natalie Brough to tell him about the adventurers' system. She gives him the essential knowledge and asks his class. Upon hearing beast tamer as his class, she becomes anxious which made Rein remember what Leanne had told him before but Rein says he'll be fine. He was then told to kill ten goblins as a registration test. Using a squirrel, he tracked the goblins and starts to attack them. He killed them off and collects the magic stones. He then hears someone's scream only to find out a girl is being cornered by a Killer Tiger. He decides to act on his knife to attack it, but its skin is so hard that the knife brokes up. As the killer tiger cornered him, he witnessed the girl jumps at a very high speed and slams the tiger. Rein sees that the girl is from the Cat Tribe were said to endangered species. The girl fell down and Rein asks whether she is okay or not. She says she is hungry. After Rein gives him some food, she gives him thanks and introduces herself Kanade. While they start talking about themselves, Rein told her about his banishment which made Kanade angry with the hero. This made Rein happy as she was angry with him and give her a pat on her head and she happily enjoyed it. She then asks Rein to tame her. At first, Rein wonders if it is possible to do so but feels that he wants to know Kanade better and give it a try which turned out to be a success.

After Rein successfully clears the trial, he now becomes an F-Rank Adventurer. As Rein was about to take a quest along with Kanade, an adventurer notices Kanade and invites only to get rejected. When he belittles Rein, Kanade got angry and tells him he is her master. So, the adventurer gives a declaration of war by arm wrestling. Rein accepts and ultimately defeats him instantly which surprised everyone including Rein himself. Then Kanade explains he had acquired the same power as Cat Tribe. Rein and Kanade go to collect medicinal herbs. Kanade complains they should do something more heroic but since he is just an F-Rank they can't do it for a while. Then Kanade hear some screams and they rushed over the scene only to find a group of bandits threatening a merchant. Rein helps them and finds out there's a hideout of the gang and further decided to knock them to avoid casualties. Rein asks Kanade to bring adventurers from the city to help them out and uses Arhbees to sabotage the bandits. As the cleanup was being done, a loud roar shook the cave. Kanade sensed danger and tells Rein it is a monster. It was a group of King Lizards who went berserk and killed the bandits. Rein and Kanade act on and starts fighting the monsters. With Kanade, Rein defeats the king lizards and safely came out of the cave.

Rein got promoted to Rank E as he defeated the bandits' gang with his direction. Some days later, Rein took an investigating quest on the watchdog of Stride Bride. Rein with Kanade reached the bridge and a witness a red dragon coming to them at full speed. who later introduces herself Tania and happens to practice on the bridge. Tania challenges them and easily overpowers them. Rein decides to fight as a beast tamer and deploys some ravens on Tania which paralyzed her. Which Tania accepts in the end. Finding Rein interesting, Tania becomes his second contractual. On a quest, Rein got stabbed due to Tania's carelessness. Later, Rein comforted her not to worry about it. Rein would later tell them about his past and how met the hero party.

The next day, Rein got confronted by his former party. Arios asks to join their expedition for navigating through Lost Forest. Rein refuses but when they mentioned saving the world, he decides to accept. As soon as the hero party is about to leave, Tania orders them to sincerely apologize to him for their past actions. This made them very infuriated and out of rage, Arios called Rein's contractuals just pets. Infuriated by the insults towards Kanade and Tania, Rein punches Arios knocking him to the ground as he tells that anyone who insults or threatens his comrades will pay the price. Filled with rage and entitlement, Arios challenges Rein and his comrades to a duel in which Rein won easily with his new profound powers. After retrieving the map of Lost Forest, Rein and others go to the forest. Tania notices they're circling around the same place with illusion magic and uses her magic to deflect the magic which revealed a big tree. Then they met Sora who is the guard of the lost forest. Rein tries to talk but she was hostile and asks them to leave the forest. , Sora frowned and was convinced o talk. After their talk, Sora gave the Shield Of Truth. Rein and the others decide to leave the forest but while noticing Sora is sad, Rein asks her if they can help her. On her request, Rein freed her twin sister, Luna. Feeling indebted, the spirit sisters became his third and fourth contractual respectively.

Rein and others, along with Sora and Luna, return to the city of the horizon. Rein gave the shield to the party. Aggath offers him to return to the party much to Arios' anger. Rein was got engrossed with thoughts but on hearing the call of his companions, Rein refuses their offer and walks away.

Beast Tamer Volume 2
Luna asks Rein why is the hero the only one eligible to defeat the demon lord. Rein told her and the other contractuals about the hero's lineage of receiving powers from gods and the concept of Limit Break. On this, Luna points out Rein might have broken his limit break as he is now the strongest race's master and others came to the conclusion that Rein might have the power to defeat the demon lord. Rein thought of giving it a try but as of now, he wants to live a happy life with them. Rein decides to gear up with equipment and goes to Gantz Storf's store. Gantz approved of him after Rein shows his keen interest and tells him that he'll make a custom weapon for him. But before that, Gantz had to require a special material, Mithril. Rein took this as a quest and goes to the mine as directed by Gantz. Noticing there are some smugglers, Rein makes a plan and sabotaged them. Rein fights with a beast tamer who raised a monster since it was a baby. The beast tamer ordered the monster to attack but Rein overwrite the contract for a while then with no choice left but to kill the monster.

Later, Sora and Luna ask to pat their heads as a reward which makes Tania and Kanade jealous. The next day, Rein along with Sora and Luna strolls around the city. While sightseeing the shops and places, they got confronted by the son of the lord of the horizon, Edgar Fromware. Edgar tells Sora and Luna to become his which disgusted both of them. Rein fronts up and asks him to leave. At this, Edgar uses violence but Rein who discovers his new powers gained from Sora and Luna defeats the soldiers instantly. Edgar runs while swearing to kill Rein. Meanwhile, Rein discusses the incident and starts collecting information. They go to the headquarters of The Knights. When they inquired about Edgar's misdoings, the knights became suspicious of them. Rein decides to leave. Wondering what do to next, they meet the vice-captain of the knights, Stella Enplace. She tells them she also wants to stop Edgar and they made an alliance. After collecting enough information, Rein gave the plan of sabotaging the veteran knights at the warehouse first, then raiding the lord's mansion. They successfully sabotage the knights with the help of Rein's taming ability.Then Rein infiltrates the mansion and ended up finding a little girl trapped in jail. Rein helps her and the girl introduces herself Niina who comes from God Tribe. He breaks her slave collar and ends her contract of her with Edgar. Meanwhile, the lord's defenses got weakened and Edgar uses the ring (given to Edgar by Arios) which summoned a Death Scythe. The death scythe stabs Rein with his scythe which happened to be enchanted with death magic. But, surprisingly, nothing happens with Rein. Luna says it is the power he got from her. Then they corner the lord and Edgar. As a last resort, Edgar used the ring again and transformed into a demon. Rein remembers the demons which were the very creature who destroyed his village. The demon flies to the city and began to attack the people and turned them into its own kin. Rein and his contractuals began to fight the demon. They were about to get cornered by the demon but with teamwork manages to deal major damage to the demon. The demon asks Rein his name but Rein refuses to do so. Then the demon disappeared and released a wide range of lighting magic. Rein searches for the demon but it became invisible. Niina came in and help them out with her special powers. The demon becomes visible and Rein killed it which also stopped the magic.

At this feat, Rein is widely known as the Hero of Horizon.

Beast Tamer Volume 3
Hailing as a hero of Horizon for defeating the demons, Rein now becomes a C-Rank Adventurer. Natalie suggests he buy a mansion for his base. Rein decides to give it a try. Natalie shows them a house near the central continent. The house is said to be haunted but they still went into the mansion. On entering, they witness poltergeist phenomena like utensils moving or flying on their own. Rein asks Sora and Luna to use her magic to see through it. They tried but could not capture it as it traveled to the Astral Side. Then again it appeared, but Rein and others find that it can just scare not hurt someday. It was a ghost. Rein controls the ghost who happens to be a maid, Tina Hollee, with his phantom abilities. With this, the house is no longer haunted and Rein buys the house. The next morning, Kanade comes to Rein's room and greets him only to find Niina cutely sleeping on his bed which caused a misunderstanding. Contractuals thought Rein might be into small girls much to Rein's dismay and Tania's and Kanade's jealousy.

At the adventurers' guild, Rein took the quest of capturing some poachers who are hunting Hornwolves. In the forest, while Rein and the party were tracing the poachers, they met two veteran C-Rank Adventurers, Kreutz Felt and Oag Stryver. Rein came to find out there has been a double booking on the quest. So, the two adventurers decide to settle it by competing who'll find and capture the poachers first. Rein, with his contractuals, easily traced the hornwolves and even captured the poachers. At this, Kreutz and Oag became angry, not wanting to accept defeat from a kid. They freed the animals and poachers while Rein's party put their guard down just to make some money but unfortunately to them, Rein and others outrun them and defeated them to the pulp. And as for the runaway poachers, Rein uses a bear and coldly injured them. After completing the quest, Rein came to find out Tran Jack is the mastermind behind the poaching and decides to arrest the knights.

Rein and the party infiltrate Tran's mansion at the night. Rein asks Kanade to bring Tina. Rein asks Tina for entering the mansion and eavesdropping the situation of Tran. When she came back, Rein notices her uneasiness and Tania tells them she began to remember her memories and the one who killed Tina and her family is Tran himself. Tina pleads with them to stop the mission but Rein questions Tina whether she wants to take revenge on Tran. Rein assures her that he and others will be always with her, this gives her a push and speaks from the bottom of her heart. Then they go to take down the guards and Rein fought the Assassin, the top bodyguard of Tran, and won in the end. Rein confronts Tran and orders him to surrender but Tran refutes this while shivering in terror. He frowns when he sees Tina who now become a ghost. Tran gets caught by the Knights.

Later at night, Tina talks with Rein alone. She humbly thanks him for doing the things he had done for her so far and finally asks him to make a contract with her. Rein tames her and later would discover his newly gained power Gravity Manipulation. Some days later, Rein and Kanade go to the market for buying some ingredients and necessities. While they were walking, they got separated in the crowd. Rein see someone's eat ears and caught her hand. He finds that he mistook her for Kanade. The cat-eared girl ponders Rein when she heard the name Kanade. He introduces himself as a companion of Kanade's. As soon as the girl was just about to introduce herself and her relationship with Kanade, Kanade herself showed up at the scene and Rein comes to know that the girl is Kanade's mother, Suzu.

Beast Tamer Volume 4
Meeting Kanade's mother, Suzu, Rein became troubled because she has come to take Kanade back to their village. He asks Suzu to consider Kanade's feelings also but thinking of Kanade as just a child, Suzu fixated on taking her back. But Rein and others start to argue and finally, Suzu, who witnessed the scene, told them to take on her trials. If they win, Kanade will stay otherwise leave. The first trial was to check the bonds between them. Rein is asked by Suzu to find who's the traitor in his party whom she talked to beforehand. Rein says there's no one and passes the first trial. On the second trial, Rein and others had to touch Suzu before the time limit. Though Rein and others were not able to touch her within the time limit, she herself touched everyone out of the time limit, so they won the second trial. As for the last trial, they have to fight and win against Suzu. Rein wins at the last moment using boost triple times. Finally, seeing their bond, Suzu approves of Kanade's journey and The Shrouds. They would later get trained by her, helping them in many ways.

Some days later, at the adventurer guild, Rein got tasked with an urgent guest to investigate the destruction of a small village Pagos. Rein was put on the investigation team along with two A-Rank adventurers, Cell Marcell and Aks Ghin. Arriving at the Jizzo village, they rested for a while. In the middle of the night, Rein walks around for some fresh air, and then he saw some men are inviting a small girl. He helps her and thank him for giving her name, Iris. They talked for a while and parted away later. The next day, Rein and the team reach Pagos which was terribly destroyed left with few survivors. Rein reunites with Arios Orlando who proudly tells Rein that he helped the villagers by stopping the demons. Rein doubts it as what he says was out of his character. Nevertheless, they go to the mountain and witness a broken shrine and a rotten corpse. They came to the conclusion some human is behind all this and decides to return to the village only to find Iris leading many demons and killing the humans. Rein tries to negotiate as he doesn't want to kill Iris but Iris says there's no turning back now, they decide to battle with no choice left. At the scene, Arios reappears and began barking at Iris for betraying him and their deal but Iris coldly says she got no reason to follow the deal and Arios too joins the battle. Being Iris too overpowered, Rein and others got cornered and heavily injured. Rein tries to reason with her and says Iris must have a reason to do the cruel acts which surprised her and compliment him for being a good-natured person. She gives them a handicap if they deal some damage, she'll retreat and would reveal her past to Rein. Using, boost multiple, and finally harnessing Kanade's power in Kamui, Rein manages to deal some damage to her. As she promised, she retreats and the case is finally settled for a while. Later, Rein reveals Arios's dirty tactics (he unsealed Iris and uses her for his own convenience by taking the credit for defeating the demons) which tarnishes his reputation even further.

Beast Tamer Volume 5
The night after the battle, Rein wanders around the town and meets Iris again. He persuades her to surrender but she told him she'll have her vengeance no matter how much Rein says so. The next day, Rein and the party go to the mountains where Iris first appeared and came to know Iris can be sealed using an ancient relic. They decide to visit the Spirit Tribe Village as suggested by Sora and Luna. Rein, from a human race, was unwelcome in the village and the elder chief was not ready to give the relic but on the approval of Sora and Luna's mother, Al, the chief gives him a chance to prove himself. The chief made Rein fight not anyone but his own reflection with the aim of bringing out his true nature. He wins the battle and successfully gains the chief's approval and retrieves the relic.

Then Rein and the party remove themselves from the subjugation team of Iris. Ax and Cell disapproved of Rein's decision as he was still sympathizing with Iris and decides to stop him and his party with their all might. Rein defeats them and proceeds to Iris's whereabouts. Rein battles Iris alone and with the help of the relic even overpowers her and finally manages to restrain her. As if she lost the significance of her life, Rein embraces her and says he'll be at her side forever. Iris then asks him to tame her when they'll meet again until she got swallowed into the shadows.

Abilities
Rein has shown extraordinary abilities that defy the logic of being a Beast Tamer

Taming

 * Beast Taming: His signature's ability to control or taming animals. It is said that a tamer can tame only one animal at a time, and if that person tries tame more than one, his head will explode. But for some reason, Rein broke these boundaries and is capable of taming many animals he wants to. As the sole survivor of his village where "special" beast tamers lived, Rein has shown the capabilities of taming the strongest and superior races with ease. Theoretically, very few people can tame superior races, especially if it's a human, and additionally, Rein had already tamed almost every superior race.
 * Insect Taming: Aside his main class, Rein is capable of taming insects. Rein said it is a sub-class of taming, so it was easy to use. According to Kanade, this ability itself is beyond unbelievable.
 * Provisional Contract: Using this, Rein can control animals for a brief time.
 * Assimilation: Rein is capable of transferring his soul to a tamed animal and can fix his consciousness into it for acting on. To deliver his thoughts, he uses magic.
 * Overwrite Taming: Rein can overwrite the contract of other tamers. Rein himself made this skill.
 * Boost: A magic that can temporarily increase the power of someone.

Acquired Abilities
Whenever Rein tames a superior race, he gets their affinities and abilities much to the extent where he exceeds them.
 * Kanade
 * Immense Physical Strength: Rein's physical powers drastically increased after taming Kanade. He easily won an arm wrestle with a fit-looking man. His current strength is completely beyond normal humans, including those who were blessed with physical and magical power when he easily defeated the "Hero" Arios twice, which makes him on par with high-level monsters. Single-handedly, Rein managed to damage a King Lizard severely.
 * Tania
 * Immense Magic Power: After taming Tania, Rein's magical powers drastically increased. Beforehand, he had learned basic magic like beginner healing and fireball. So as of now, his magic stats booms up just like a dragon's. Tania's magic is more powerful than magical blessed humans such as Mina and Lin.
 * Magic Power Boost: Rein has displayed a major boost in magic as he trains under Tania.
 * Fireball: Rein can use massive firepower with a long range.
 * Healing: Rein can use beginner heal, and Tania's acquired magical power improved his healing skill greatly.
 * Sora & Luna
 * Extreme Control Techniques: Rein gained this ability from Sora, and with this, Rein has shown magnificent control in his magic and spells.
 * Consecutive Chanting: Rein can multiply his spells with enormous magic power.
 * Fireball Multi Shot (ファイアーボール・マルチショット): With the help of consecutive chanting, Rein can unleash multiple fireballs.
 * Multi-Boost (マルチブースト): With this, Rein can use boost on multiple targets.
 * Abnormal State Nullification (状態異常無効化): With this, Rein is absolutely immune to death magic. Rein also gained a high level of resistance when Luna used "Poison Drop" on him to test his ability.
 * Niina
 * Material Creation (マテリアルの作成): Rein can able to create something by his imagination. He cast magic and then, instead of consuming magical power, a certain substance was generated.
 * Tina Hollee
 * Gravity Manipulation (重力操作): Rein can easily float in the air
 * Rifa
 * Magic Eye: Rein is able to paralyze or charm whoever look into his eyes.
 * Finia
 * Recovery: rein is able automatically heal from injuries

Others

 * Limit Break: Beast Tamers are normally only able to control one single, normal animal at a time. Rein, however, is not only able to tame multiple animals at once, he can form contracts with the ultimate species; humanoid races with incredible power. Doing so allows Rein to share their powers endowing him with Kanade's physical strength, Tania's magical power, etc.. It's implied that all Beast Tamers in Rein's hometown were just as capable, but his village was destroyed when Rein was twelve years old, leaving him the sole survivor. The only beasts he can't or hasn't yet attempted to tame are monsters like Goblins, King Lizards or Killer Tigers, instead opting to steal from or kill them like other adventurers.

After the first victory against the Hero Party, it is suggested by Sora that Rein may not have any upper limit to his potential growth. All mortals in the setting are subject to such a limit, a point at which they can become no stronger no matter what they do. The only known exception to this is the hero Arios, as he's descended from a prior hero who was giving the "Limit Break" ability by the gods. It is for this reason Arios is considered the only one potentially capable of fighting the Demon Lord. Sora theorizes that Rein's Power copying may work in much the same way: offering a way for him to become continually stronger with every contract he forms.


 * Expert Strategist: Rein has displayed some unique and clever tactics, which made his foes difficult to comprehend to do so. With his sole command, he sabotaged the garrison of experienced soldiers. His plan also defeated the whole Jet Black Fang.

Equipment

 * Narukami (鳴神): A personalised weapon made by Gantz Storf. It is in the shape of a hand glove so Rein wears it on his right hand. It has been equipped with many gimmicks, like shooting needles by performing a specific movement.
 * Ultra-Fine Wires: Another gimmick equipped in Narukami by which Rein can shoot wires to ambush his opponents.
 * Paralyzing Darts: Another gimmick equipped in narukami by which rein able to shoot darts from the Glove by making a specific movement with his hand



Kanade
Rein's first contractual. He met her on his first adventurer quest and tries to help her to fend off the Killer Tiger attacking her, which is later killed in one blow by Kanade. After hearing his explanation, Kanade gets angry at Rein's previous party members. She then asks him to tame her, which makes Rein deeply think about whether it's possible to do so. Kanade assures him that she knows he can do it as if they were fated. Rein successfully tamed her. As his first companion, Rein feels a deep bond between him and her and wants to know more about her. Kanade is quite intolerable to those who belittle Rein, often stating him a great master and a great person. She is always cheerful around him and helps him on quests. Though for others, it would seem they're just besties, Kanade begins to fall in love with Rein when she says she greatly admires his kindness and feels her heart is racing very fast. She has yet to realize her very emotions and feelings for Rein.

As if felt refreshed whenever she battled along with Rein, she is also a source of Rein's sanity. Kanade loves to receive head pats from him and often gets jealous whenever other contractual get so, or some girl tries to get close to him.

Tania
Rein met Tania when he took a quest to investigate Stride Bridge, who happens to engage in mock battles which branded her as a rogue. Tania challenges them to a battle by feeling a strong presence in Rein and Kanade. She estimated Rein as a top-notch adventurer who makes her more fired up. Even though it was a 2v1 battle, Tania easily overpowers them. As the offensive was not a good choice, Rein decided to fight like a beast tamer. While he got sent flying, he sensed the presence of Pito and used it to paralyze her. She was left with no choice but to give up, only to get asked to come to the city by Rein. She thought he would sell her somewhere, but he refused and says he just wanted to talk and to promise not to pick up fights. She accepts this and later decides to join their party, thinking it would help her in her training, and also reveals her interest in Rein. Tania asks him to make a contract with her since, according to her, it is natural to do so. Rein tames her making her his second contractual.

After their contract was a success, Tania feels they'll be connected forever. As a party member, Tania teaches him how to control magic power efficiently, and with just basic spells, he can do a lot of damage to his opponents. However, he feels her training is very spartan. Tania often refers to him as a "too good a person" as he always sacrifices himself or sometimes goes overboard but also feels it is not a bad thing. She feels proud of having a master like Rein, which shows how much she respects him as a person. On their orc subjugation quest, Rein asks Tania to be careful, but her overconfidence becomes a little shallow, leading Rein to get stabbed by an orc as he saves Tania from hurting. She then feels tremendous guilt and does not find herself how to face him. When Rein talks with her and asks what happened, she apologizes very much for her carelessness. He replies that she should not have to worry about it as he was not mad but was happy when Tania realized her mistakes. Tania starts reminiscing about him. At first, she only followed him out of mere interest. Rein made her feel very secure and comfortable, realizing her chest was feeling warm. At this very point, she falls in love with him, but because of her pride, she refuses to accept that. Just like the other Rein's contractuals, she loves to get patted on the head by Rein.

Sora
Rein met her in the lost forest but their first meeting was rocky as Sora hates humans. Though she was hostile to him, she politely asks him to leave the forest. But due to Rein's kind nature, he requests her to listen to them and still gets rejected but this doesn't stop him to convince her to talk. Sora shoots her magic at him but Rein remained unfazed and gives her a smile, much to her surprise. When she questions why Rein is behaving like that, Tania and Kanade said he is like that. This made Sora trust Rein a little and eventually gave them the Shield Of Truth. As soon as Rein and the others were about to leave the forest, Rein notices Sora is sad. Rein asks her if she needs some help and put her faith in him, Sora asks Rein to save her twin sister, Luna. After saving her sister, she sees Rein in a different light. Though she loathes humans, she finds Rein an exception.

As a contractual, Sora was worried since Rein hasn't shown the signs of her powers and the contract was just one-sided. This tension was gone when Rein was able to consecutive chant. Like other contractual, Sora loves to get head pats from Rein and wants Rein to rely on her more.

Luna
