A slum boy, Aiden, gets an awakening serum bought with his father's blood, but a rich girl pours it out and humiliates him. He awakens SSS Tri-Color Lightning, only to be framed by genius Damian and Principal Aldric, who force him to kneel publicly or lose his trial spot. For his sick mother, he kneels. But no one knows his secretly tested combat power already dwarfs them all—the real trial begins in three days.
