Hachigaya Akagami, a former high school student reborn into another world, is blessed by the black slime god and becomes the strongest. With that power, he builds the organization he once dreamed of, after witnessing the incompetence of heroes in public spaces. At that very moment, he creates the concept of the “reserve heroes,” a group that operates behind the scenes, eliminating evils that conventional heroes are generally unwilling to face.

“Delusion? No, that is not it. This is a requirement of the cosmic system, meant to neutralize both black and white narratives.”

Becoming the strongest may sound like a template story. However, attempting to perfect the system using overwhelming power is an essential mission that must be carried out.
