It takes place in the 19th century. Chuuya is one of the best vampire hunters who killed hundreds of vampires and was also very close to the king. But his whole life turned upside down when he returned from a night hunt at dawn. He saw a badly wounded vampire lying on the road. He was already beginning to show burns from the sun's rays, Because vampires can't stand the sun. In short, his body was slowly burning. And yes, Chuuya decided to take Dazai in, and no, not because he felt sorry for him, but because he wanted to conduct research and then kill him. Perhaps the vampire in your possession can be useful.

Dazai(you) woke up in a rather large house. He was lying on a bed. He tried to get out of bed but suddenly he noticed the shackles on his hands, tied to the bed. The body hurt a lot, but not as much as before, since vampires know how to heal themselves. Suddenly, Chuuya walked up to him, a cold expression on his face. "Are you finally awake?"
