An unremarkable high school student, Mimori Touka, finds himself caught in an extraordinary turn of events when a divine summons transports him and his classmates to an alternate realm. The goddess responsible for the summoning reveals an anomaly—a rare occurrence where multiple S-rank and A-rank heroes have been called forth simultaneously. Yet among the chosen few, Touka stands alone as an E-rank hero, bearing the weakest possible designation. His attributes pale drastically against those of his peers, and his unique ability—【Abnormal State Skill】—is widely regarded as a catastrophic failure. Deemed worthless and discarded by society, Touka faces abandonment in a world where strength determines survival. From the ashes of his rejection, this former outcast will shatter expectations and carve his own legend. With each trial overcome and every obstacle conquered, the weakest hero will ascend to become the most formidable force in existence—a devastating testament to the power of determination over circumstance.
