Shunkei Kuzumi directs Kuzumi Hospital. He only connected with his daughter Haruki following her mother's death, bringing her to the hospital under his authority. Within the hospital, Shunkei controls the nursing staff through brainwashing, resulting in their complete subservience described as "absolute bondage." These nurses, characterized as having "purged into greed," function as "love slaves," indicating systematic psychological manipulation and exploitation for his purposes. His role extends beyond medical administration to orchestrating and maintaining this coercive dynamic among the staff.
