You used to be an ordinary teenager, a high school student. That carefree time when, it seemed, there was nothing not to think about and not worry about. You had no idea how fast time passes and how at any moment everything can turn in a completely different direction.

Demons have been surrounding Japan for a long time, demon hunters are dying every day, there are not enough of them, and then it came to your school. They started taking students from your school to work, making them demon hunters. Some signed contracts, some became half-demons, naturally, a lot of deaths. You didn't think this would happen to you. You were made a demon hunter, and forced to contract with a very powerful and dangerous death demon. And thus you became a half-demon.

Despite the fact that now schoolchildren were becoming hunters, everyone continued to go to school, it was necessary to study.

And even though it's been about a year since you became a demon hunter, you'll never forget your first day of work. More precisely, it was because of your partner, Yoshida Hirofumi. You fell in love with him as soon as he was called to be your partner. He was a little older than you, by two years, and naturally more experienced at work.He is handsome, tall, fit, broad-shouldered, has dark medium-length hair, and dark, almost black eyes like a dead fish. You want to go underground under his gaze, but you like him. By himself, Yoshida is calm, collected, and introverted. he doesn't talk much, either on business or with short answers. He also has a contract with the octopus demon.

And you tried to show up to him, with him you forgot about all the demons, or the fact that you are now not just a schoolgirl, but a half-demon of death.But he didn't answer, ignored all your hints, as if there was nothing.It made you mad, but there was nothing you could do.

After you became a demon hunter, and after signing a contract with a death demon, you became a half-demon, you have your own abilities. Because of the demon's power, you can absorb everything like a black hole, or rather, you were. After signing the contract, a large long crack appeared on your stomach, like an incision, in which there was nothing, nothing, blackness. It was a black hole that swallowed everything. Past that, you've got another instinct. You wanted to eat, not like an ordinary person, like a demon, your mind and body wanted flesh. and you, like the other half-demons, were fed special food. But you were always afraid of him restraining his instincts and eating someone, most of all, you were afraid of harming Yoshida.

One day, after work, you were returning home. You were covered in blood after killing demons, battered, tired. And suddenly your instincts kicked in, and you saw another demon hunter. You recognized her, she often hit on Yoshida, and after those memories, your instincts kicked in. You attacked her and ate her. Sated, satisfied, a sharp panic swept over your body, did you really do that?

You didn't know what to do, your legs took you somewhere.. more accurately.. To Yoshida's house.
