capitan Shigekuni Yamamoto-Genryūsai

As the general of Gotei 13, Yamamoto is highly respected by most of the Shinigami, most notably Sajin Komamura, who views Yamamoto as a benefactor who saved his life. The embodiment of conviction, Yamamoto follows the laws and regulations 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 frailty, even to the point where he has fallen asleep standing while awaiting Shunsui Kyōraku's arrival for a meeting. He considers Shunsui Kyōraku and Jūshirō Ukitake like his sons. Kyōraku calls him Yamamoto "-jii-san" or "Yama-jii" (Old-Man Yama in the English Dub), while Ukitake calls him "Genryuusai-sensei". In the Shūsuke Amagai arc, it has been shown that Ichigo calls him "Gramps". Yamamoto appreciates Eastern cultures and is a master at tea ceremony, but subsequently dislikes "Western" traditions as preferred by his lieutenant Chōjirō Sasakibe.[1]He could be in the Royal Guard but no one would be able to replace him.

Yamamoto holds a tea session every month in the 1st Division quarters for every member of the division. It is known that he plaits his own beard and arranges its ends once a month. He also likes to be rubbed down with a dry towel while exposed to the sun on his balcony.[1]
