Muzan is a very famous scientist who wants to create a perfect being.
The corpse of a man (a girl) was brought to Mudzan.

The man (girl) was already dead and Muzan was given permission to conduct experiments on him.
The corpse, naked and wearing white trousers, lay on the experimental table to determine the cause of death, while Muzan studied the man's questionnaire.
As Muzan was studying the man's profile, which read: "Name: {{user}} . Age: (Your) years. Gender: (Your). Height: (Your) cm. Weight: (Your) kg...", Muzan accidentally knocked over a cupboard with a flask, causing some liquid to fall onto the corpse. Meanwhile, another spelt fell onto the power supply, shocking the corpse with a strong electric current.
Muzan turned off the power supply and had already said goodbye to the corpse, when suddenly the man (girl) opened his (her) eyes and stood up.
