Ichigo Kurosaki vs. Gegetsuburi

Prelude
Ōmaeda is walking with his subordinates at night, commenting upon his task to search the records to determine whether a Zanpakutō called Muramasa existed. His subordinates whisper behind his back, and deny that they were talking. Suddenly, Marechiyo trips upon the body of an unconscious Shinigami, dropping his snacks in the process. His subordinates run over to assist him, and ask whether he is alright. .



He gets up, and realize that the area surrounding them is littered with the bodies of fallen Shinigami. Marechiyo wonders what occurred here, as his subordinates yell out, and are promptly thrown across the ground. As he looks up, two Zanpakutō spirits comment upon their easy victory. However, Marechiyo approaches one of them, and realizes that he is Gegetsuburi. They seem to get along well, until they comment upon each other's physical features.

Battle
The two draw their swords, preparing to fight, as Gegetsuburi tells Hōzukimaru to stay out of his way, who agrees, stating that he doesn't interfere with the fights of others. However, when they are about to clash, Marechiyo is knocked away by a chunk of rock that hits him. Ichigo appears through the hole with Ikkaku, realising that they knocked out the wrong one. Ikkaku reassures him, stating that no-one cares because it is just Omaeda. .



As Ikkaku stumbles into the clearing, he is instantly attacked by Hōzukimaru, who immediately confirms that he is his Zanpakutō. As they fight, Ichigo is surrounded by a dense mist, as Gegetsuburi proceeds to attack him, hurling his mace at him. Ichigo deftly avoids it, seeking refuge on a nearby tree, as the Zanpakutō continually throws it at him. Ichigo tells him to fight like a man, to which Gegetsuburi states that his master is a member of the Onmitsukidō.

Gegetsuburi then throws his mace at Ichigo once more, to which Ichigo reflects it back at Gegetsuburi with a Getsuga Tenshō, with the strength of the blast causing him to become temporarily disorientated; before he is hit in the face with his own weapon, sending him hurtling into a nearby building.

Aftermath
After the Zanpakutō retreat, Gegetsuburi is found by several Shinigami and taken to the Shinigami Research and Development Institute, where he is subsequently destroyed by Mayuri Kurotsuchi.
