勇者パーティーを追放されたので、魔王を取り返しがつかないほど強く育ててみた
Reisel is summoned to a different world to battle a demon tribe but is rejected and expelled due to a power assessment indicating he has no combat ability. The evaluation was incorrect, as his strength is actually beyond what anyone in that world can measure. After being exiled, Reisel explores the world and comes to understand that the demons are not as hostile as believed, choosing to align with them instead. Over time, the demon tribe, now accepting Reisel as an ally, begins to flourish, while the kingdom that cast him out deteriorates.
