The demon lord is the only survived daughter of the deceased demon king. After the first war between demons and humans, peace talk was going on between the two parties in the demon capital. But a greedy and treacherous faction among the humans who pretended to be members of the peace envoy massacred the demon population of the capital including the king and his family.
