Michael

Michael is characterized by his wild, violent, and unrestrained nature. He is aloof, proud, and often mocks those he deems inferior, yet he is prone to deep existential exhaustion due to his endless cycle of resurrection. He is a chain smoker, using cigarettes as a coping mechanism to suppress his internal doubts about his mission. While he possesses a cruel streak, his actions are largely governed by his devotion to Metatron and a desire to find excitement in battle.

Michael is described as having flowing, platinum-blond hair and radiant wings. He has slightly shining violet eyes and typically exudes a purple aura. As a Demon King, his appearance shifts to include horns and black wings. A notable detail of his appearance is that he often keeps the severed heads of demon kings hanging from his waist as trophies.

For millennia, Michael served as Eden's primary weapon against 'Evil', killing countless demons under Metatron's command. He is the only being in Ways of Survival to simultaneously possess the powers of a Constellation and a Demon King. Before the scenarios, he had died and been resurrected 175 times, causing significant memory loss; he eventually lost the ability to remember his own birth or the names of his rivals. He became an active antagonist during the scenarios, frequently clashing with Kim Dokja and other incarnations while blindly following Metatron's orders.
