Gyōkaku Kumoi

Gyōkaku Kumoi (雲井 尭覚, Kumoi Gyōkaku?) introduced during The Captain Amagai arc, is one of the clan leaders serving the Kasumiōji Clan. He appears to be the main antagonist of the arc, apparently replacing Sōsuke Aizen.

Appearance
Kumoi is seen in two outfits. The first is a white kimono with a purple wrap, looking similar to a sweater. The second is the standard Shinigami uniform with a red kimono over it. He has white hair slicked back, large sideburns, and one spectacle in his left eye. When smiling, it is noticeable he is missing a few teeth on the right side.

Personality
Kumoi often adopts a smiling and benevolent expression in front of public appearances, which belies his evil and cunning nature. He was believed to be power hungry, wanting to take Rurichiyo's position as the head of the clan, but was revealed to work for Shusuke Amagai.

History
Kumoi is the steward who handles most of the family affairs. However, when Rurichiyo's father passed away due to illness, he has planned to usurp the head family seat, gathering supporters and creating an assassination squad for his own purposes. He has his assassins kill off the clan leaders in the noble family who disagree with his views or discover his plans. His main goal is to kill Rurichiyo, the last true descendant of the Kasumiōji family, which he has failed to on several occasions back in Seireitei.

Synopsis
When Rurichiyo Kasumiōji enters her family compound, Kumoi finds her. He then order Hanza Nukui to kill her, but is stopped by Ichigo Kurosaki and Kenpachi Zaraki. Kumoi, however, manages to trap Rurichiyo guards. When Hanza fights Ichigo and fails, Kumoi sends him and a dozen other assassins to the human world, each sporting a Bakkōtō. The next day, he is seen installing Shū Kannogi as the head of the clan.

Hanza, still angry over his defeat, gathers three criminals and brings them to Kumoi. He agrees to send the four to the human world with Bakkoto to kill Rurichiyo and her friends. The only of the assassins to survive is Ryū Kuzu, who Kumoi replaces with Makoto Kifune, after ordering Ryu to be killed.

In order to keep Kumoi in line, Rurichiyo agrees to marry Shu. However, Ichigo, Rukia, Kenryū, and Enryū tries to stop them. Soifon and the patrol corps corner them and Enryu releases his zanpakuto, giving Ichigo the opening to reach Shu. Together, they escape, pretending to take Shu hostage.

Ichigo enlists the help of the new 3rd Division captain, Shusuke Amagai, in saving Rurichiyo. When they enter the compound, Kumoi takes Ruricihiyo hostage, but is quickly killed by Shusuke. He then takes Rurichiyo with him to Yamamoto, who he intends to fight. Just before dying, he mentions that he did everyhting he was told to.
