Kōga Kuchiki is released from his prison. A flashback from several hundred years ago occurs, explaining the circumstances of Kōga’s acts during a civil war, where he fought with distinction, his relationship with his father-in-law, Ginrei Kuchiki and Genryūsai Shigekuni Yamamoto, who put a special forces unit under Kōga’s command, and his betrayal by other elites which leads to his arrest by the Onmitsukidō and Ginrei Kuchiki. Muramasa breaks out the cell and asks Kōga to go with him, which he agrees, but makes it clear he is charge. Back in the present, Ichigo Kurosaki and Rukia Kuchiki attack him, but are repulsed. Muramasa approaches Kōga, only to be stabbed by his master.
