The Apocalypse of the Heroes

Shirase Kou and his 35 classmates were summoned to another world as heroes and forced to kill each other in order to unleash the hero's true power. Caught off guard by the sudden situation, Kou and the others were treated like slaves by a mysterious group, and with no choice but to fight, their classmates gradually began to accept combat. However, amid all this, Kou becomes the target of hostility due to certain circumstances and, despite being looked down upon as incompetent, he survives numerous deadly situations and grows stronger. And so Kou continues to fight—sometimes clashing with his classmates, sometimes joining forces with them—to resist their fate. ※While this concludes at a reasonably good stopping point, it ends with a "Our battle is just beginning!" style conclusion. Please be aware if you are reading from the beginning.
