Hero Has Returned

After saving another world, Minsu Kim finally returns to Earth expecting to reclaim the life he lost. Instead, he discovers that everything that once anchored him is gone. Broken by the return, Minsu turns the overwhelming power of a summoned hero against his own world and begins destroying the society he once wanted to come home to. During his rampage, teenager Jeongsu Park loses his family and is sent to another world, where he becomes a warrior himself. When Jeongsu eventually returns to Earth with the strength to fight back, his revenge against Minsu becomes part of a far larger conflict among returned heroes, each carrying powers, trauma and ideals from the worlds they once saved.
