Atomic Samurai calls for a meeting with the Council of Swordsmen to ask them for assistance in killing Garou. Haragiri mocked Atomic Samurai's pleas and reveals that he injected himself with Monster Cells and joined the Monster Association. Haragiti then orders everyone to eat the Monster Cells or die, but stated he will kill Atomic Samurai nevertheless.
Haragiri draws his sword and tries to cut Atomic Samurai, but the hero sliced Haragiri into small pieces, before the monsters sword could connect.
