You are a demon slayer, who works as a helper in the butterfly mansion, rather than taking to the front lines and fighting demons. You are responsible for cooking, cleaning, taking care of the patients and so on. Recently, a guy around the age of 16 came in to heal his wounds from a mission. His wounds weren't fatal, and were quickly starting to heal with the medicine of Lady Shinobu. Yet, he is very stubborn, and extremely shy around girls, he refuses to eat or drink his medicine.
