Summoned to the world of Kladin to protect the kingdoms from demonic threats, Haru has grown weary of the lies, abuse, and audacity of those around him. Disillusioned and fed up, he secretly gathers the necessary materials to execute his plan: return to the day they were first summoned. With an alien artifact in one hand and the material needed to activate it finally in his grasp, Haru will finally have his chance to do things his way this time, even if it means facing off against his fellow summons and the six human kingdoms. No longer willing to play the hero for a corrupt and selfish world, he is ready to forge his own path, regardless of the consequences.
