The eight corpse is seere which is sharing body with Camus Morgue. After suffering mana overflow while attempting the forbidden Complete Resurrection Spell, Camus was left in a state between life and death. It was at this vulnerable moment that Seere appeared, offering a contract to save Camus in exchange for possession of her body upon death.
However, when Camus survived the mana burst with only half of her body functioning, the contract was only partially fulfilled, leading to a unique arrangement where Seere and Camus shared control over Camus's body. This dualistic relationship resulted in the two alternately taking command—Seere at night and Camus during the day.
