Nina

Nina (ニーナ), a member of God Tribe, was worshipped as a deity in her homeland until she is captured and sold into slavery, where she is put magic collar to restrain her and enslaved by Edgar Fromware. After being saved by Rein Shroud, she became his fifth contractual.

Appearance
Nina looks like a child with fox features, including fox ears and three fox tails on her back. She usually wears her traditional dress.

Personality
Nina is a gracious person; for instance, for the sake of people, she accepts being enslaved by Edgar. After getting enslaved by Edgar, she resisted his lashings and never stopped longing for someone to help her. When Rein came to her rescue, she was initially scared because of her trauma, but Rein's kindness touched her. She always thinks of others' well-being no matter how much horrible a situation she is in. As Rein breaks her collar to terminate her contract with Edgar, which makes Rein feel severe pain, Nina shows a melancholy nature and says he should stop it as no one will be sad if she dies. But Rein refuses this, replying he'll be sad. This causes her to trust Rein fully; surprisingly, she finds his recklessness a unique trait.

She hates Edgar for mistreating her and has no qualms about allowing her fellow slaves who were freed to beat her so-called "master" into a bloody pulp. She also hates Arios and wants to kill him for what he did.

Background
Nina lived in a shrine deep in the mountains, hailing as a "goddess". She was glorified by the neighboring villagers and was sleeping peacefully. She lived a peaceful life until Edgar heard the rumor about her and enslaved her using a magic collar. Since then, she has had to face Edgar's violence and torture. Rein freed her and, in the process, became his fifth contractual.

Abilities
As a member of the god tribe, Nina's abilities are regarded as out of the world. Though she's still an infant who can't completely yield the true powers of the god tribe, Nina still has incomparable powers, making her one of the strongest characters of the series. Rein has once stated that she can do the impossible possible.
 * Divine Protection (神の加護): A defensive ability that allows Nina to create an invisible shield. She manifests the shield when she senses danger. The shield is too strong to be broken until Nina herself nullifies it.
 * Instanteous Transition (瞬間転移): Making use of space, she can instantly transfer from one place to place. She can even transfer her targets to different locations.
