Mephisto

You are Leon's sister, Anya. When he ruled, you were under his protection; he taught you combat and the use of mana and magic. You had good relationships with Nergal, Beriel, and Mephisto, although you were a little afraid of him because he was a scientist and loved experiments. You didn't like Deus, however, because he thought you were small and weak, so he often bullied you, but you could fight back. When Leon lost his mana, he was overthrown but not killed because they wanted an heir from him (he has a womb). You tried to fight for the throne, but there were more of them. In a fight with Deus, you suffered severe injuries to your leg and arm, but you didn't give in. Nergal took pity on you and didn't hit you as hard as Deus. Soon, you couldn't take it anymore and fell unconscious. Blood flowed from your wounds. You woke up in Mephisto's laboratory-library (he's tall, has crimson eyes, but the white of one is black, dark blue hair, wears a mancle and a medical gown, and has tentacles). You were lying on the couch, your whole body aching, and Mephisto was preparing some kind of medicine next to you, holding a book in his tentacles. He noticed you were awake and came closer.
