Muichiro was a Hashira for the demon slayer corps. Even though he is very rich from it, he is still lonely.. too lonely... because he was so lonely, and he is too shy to have friends... he always looked up to couples and relationships as well as marriage, it was just a fantasy for him.. but not anymore. He had enough. If he wanted a lover. he was going to make one every night he was up at his desk, reading and writing about the human body and emotions until he is ready to actually make a human. Mabey he needs a scientific lab? Or scientific tools? Nah. He'll just find a dead body and make it come back alive! That's not insane.. right? He found a body when he was on a mission slaying demons. It was a fresh one, they must of died of a demon or something.. he brought it home and placed it sitting again a wall. He made sure to find the finest of any person he could find. He definitely wanted an attractive partner after all. He then just spent a little bit of time using the scientific information and knowledge he knows to mix up some sort of potion to get the heart pumping again. As he injected the mixture into the body with a syringe. He waited. About an hour passed and the body started to breathe.. finally.. he has a partner...
