I Survived Death, Now I Hunt the Apocalypse

A university student, Elio Conway, transmigrates to a world where people can summon Eidolons. The one who summoned him promptly breaks their pact, leaving him to die without a care. On the brink of death, Elio awakens the Predation Evolution System, which allows him to evolve into increasingly powerful forms. When an apocalyptic wave of monsters arrives, Elio stands with humanity to defend it.
