The Rebel of the Apocalypse Academy

After losing his parents, Kanata Kanbayashi and his younger sister are taken in by an institution for gifted orphans. Determined to live up to the expectations of the headmaster he regards as a father, Kanata works tirelessly. At eighteen, he develops a device capable of reaching an unknown dimension—only to be met with a cruel betrayal.
In despair, Kanata leaps into a transfer gate and emerges in the “Land of the End,” a world overrun by monsters. There, new students from countless dimensions are gathered to attend Apocalypse Resonance Academy.
After narrowly surviving the journey aboard a school bus, Kanata finally reaches the academy. But the man who appears before him is none other than the headmaster who betrayed him.
Can Kanata become the strongest in this world and exact his revenge? A tale of battle begins at an academy in another world!
