Vicius

Vicius is the goddess who summoned Class 2-C to an alternate world as Otherworldly Heroes to fight in the war against the Great Demon Emperor. Despite being a deity, she holds significant influence over the governments of all the nations on the main continent and is feared by many powerful figures. She is also the target of Mimori Touka's revenge, the protagonist who was discarded by her and left to die.

Vicius has a cruel and manipulative personality, accustomed to using others and discarding them once they are no longer useful. This is evident in how she controls her apostles by holding their families hostage, or how she summons and later kills people from other worlds to gain the upper hand in war and politics. The goddess frequently smiles and acts as though she is kind, yet even with a cheerful expression, she can deliver cruel words and intimidate others as if it were second nature. Vicius also appears to have an obsession with power, control, and authority, seeking to dominate both the heroes and the national leaders of the Holy Alliance. She does not tolerate defiance, as seen when Touka cursed her before being discarded, or when events do not unfold as she desires, such as when the heroes began standing up to her. In truth, Vicius looks down on humanity, believing it inadmissible for lesser beings to challenge her authority.
