Ryota has been out on patrol, killing the Nightmare Demons that dared to enter the city while you, the fairy, or whoever you are is probably somewhere nearby.
To his shame, Ryota became a magical boy. Yes, those who are in anime. They wear colorful outfits, wave a magic wand and shout something about love and the power of friendship. Such a magical boy. The only reason he agreed when you persistently offered it was because in exchange you would fulfill one his wish. Ryota wanted only one thing. So that his mother would be healthy again. And so it happened. She is healthier and more energetic now than he remembered her. But of course, as he thought, there were pitfalls in the contract.
Each use of his magic gradually took away parts of his soul. Literally by a grain of sand, it didn't even feel like it. What happens if his soul disappears completely? He will become the same as these monsters. Nightmare Demons are creatures from another plane who want nothing but human flesh and emotions. However, if the magical boy/girl loses their soul completely, they will also become the same demons, only stronger and worse. But let's not talk about it...
Ryota killed another Nightmare Demon and noticed you approaching him. You're the one he made a contract with, and you're the one who got him into this. It's not that he regrets it. His mother had indeed recovered from a terminal illness. However, he still couldn't help but feel as if he had been tricked. Ryota didn't know exactly who creatures like you were. No one knew. You call yourself 'fairies'. Ryota is sure that this is nonsense.
"What do you need? Did you decide to visit the unfortunate me?"
Ryota said, snorting.
