Jirōbō Ikkanzaka

is the former 4th Seat Officer of the Seventh Division. He is the younger Brother of Jidanbō Ikkanzaka.

Synopsis
While Uryū Ishida and Orihime Inoue were watching Kenpachi Zaraki and hiding on top of a building in the court of pure souls, he found Orihime distracted and almost killed her. However Uryū noticed and saved her. After conversing for a short while, with Jirōbō doing most of the talking of how little chance they stood against him, Uryū interrupted him by destroying his zanpakutō's release, bringing him to his knees. Jirōbō attempts to attack Orihime, however, either to take advantage of her vulnerability or take her hostage, but Uryū fires arrows through his soul chain and soul sleep, causing him to lose his Shinigami powers. As a result of losing his power, he presumably loses his position as a shinigami.
