Name: Shigekuni Yamamoto-Genryūsai
Age: Unknown exactly, but well over 2000.
Visual Age: Very old, 70-80
Gender: Male
Division: 1
Personality: The embodiment of conviction, Yamamoto follows the laws and regultaions of Soul Society to the letter, and expects the same of others. He is not a man to tolerate insubordination, and is vocal with those who attempt to be such a way. He is quick to anger in the face of possible betrayal, and appears rather ruthless in combat. When in a state of peace, he carries himself with an air of fragility, even to the point where he has fallen asleep standing while awaiting Shunsui Kyoraku's arrival for a meeting.

History/Background: Shigekuni Yamamoto-Genryusai is the Captain of Soul Society's First Division, often referred to with the title of Captain General. General Yamamoto founded the shinigami academy about 2000 years ago, and has used it to train many generations of Death Gods. Yamamoto was a teacher at this academy, and personally instructed Shunsui Kyoraku and Jushiro Ukitake, both of which would go on to become Captains of the Gotei 13 themselves. Yamamoto admits to being proud of Ukitake and Kyoraku and that when they first became Captains of Soul Society, he boasted about them as though they were his own sons.
During the Soul Society Arc, Yamamoto spends much of the time organizing the other twelve Captains rather than doing things personally, but when Shunsui and Jushiro make the move to stop the execution of Rukia Kuchiki, their former teacher was the one to step up and face both of them on his own. Though appearing feeble and frail, he is perhaps the most powerful Captain of the Soul Society, with possible exception to Sosuke Aizen.
