Set two years following the Red Hole incident, Senji is a police officer using his Branches of Sin to fight criminals, but has little temper. One day, he rescues a boy named Izuru who stole from a gang called Goreless Peace. After returning him to an orphanage, Seiji encounters Goreless Peace's chairman, Keigo Ugachi, who also possesses Branches of Sin. When Senji refuses to join him, he burns down the orphanage and kills everyone in it, including Izuru and the caretaker. Devastated, Senji goes to confront Keigo, gaining some support from his police acquaintances. However, Senji finds himself in a giant spider web formed from Keigo's powers. When Keigo injures Senji's superior, Senji manages to break the sound barrier to break through Keigo's ability, barely holding back enough to not kill him.
