Ōko Yushima

Yushima is a Shinigami of the 12th Division and worked in the Shinigami Research and Development Institute.

Apperance
Yushima bears a great resemblance to Kageroza Inaba, having long green hair and brown eyes. During his time with the Eleventh Division, he wore the standard Shinigami shihakushō. After he was transfered to the Twelfth Division, however, he donned a long yellow robe that buttons up in the front and protrudes upwards from the neck, covering the entirety of the back of his head, the same as Kageroza wears.

Currently, he wears a white robe, sitting motionless in a cell.

Personality
Yushima comes across as shy around others. He took great pride in his research, becoming deeply enraged when the Central 46 canceled Project Spearhead, screaming at them while demanding a reason for why they shut down the project and doing everything he could to preserve that research.

History
Yushima had a difficult time graduating the Shinō Academy. When he eventually graduated, he was placed in a combat oriented division, however, because his superiors thought that he was not cut out to fight, he was transferred to the Twelfth Division and the Shinigami Research and Development Institute, because he was smart and a hard worker.

He was the leader of Project Spearhead, however, the Central 46 discontinued the project, leaving Yushima enraged, demanding an explanation. As a last ditch move, he tossed the data on Mod Souls into the Dangai, and transferred some of his memories to Kageroza Inaba, a mod-soul he had created, just as the Shinigami came to arrest him. This left him in a seemingly unconscious state.

Gotei 13 Invading Army arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material. Yushima seems to have been confined to a small cell in Kageroza's lab, where he sits in a chair, un-moving. When Kageroza returns to Soul Society from Karakura Town. Kageroza visits his cell, commenting that it is useless to run from him. Kageroza then laughs wildly.

Later, after his confrontation with Retsu Unohana in the Institute, Kageroza returns to the cell. He reassures Yushima, stating that Nozomi will return to Soul Society without fail.

Once the Reigai defeat the captains, Inaba returns yet again, after having a disturbing dream. He goes to Yushima and asks him why he is worried. He tells him that everything is going to plan. Inaba asks if he is worried about Nozomi, saying that it is only a matter of time. Coughing up blood, he explains that he expected to be injured by the originals as they are not fools. He tells Yushima that he will see to it that the world will learn of his wish.
