Aoga is a tall man with short black hair and a long thin face with small eyes. He wears the standard Shin'ō Academy male uniform and he has his Zanpakutō on a strap across his back.
Upon becoming a member of the 4th Division, he wears the standard shihakushō with the medical backpack for said division.
Aoga was a classmate of Shūhei Hisagi. As such, he was a mentor to Momo Hinamori, Renji Abarai and Izuru Kira. Along with Hisagi and Kanisawa, he helped lead a group of academy students on a training mission to the material world to practice performing konsō.
When Hisagi was about to end the day's training, Kanisawa was killed by a Huge Hollow. Aoga immediately tried to avenge her, but he was injured by the same Hollow before he could attack it.
Aoga survived the ordeal and, realizing that he was not suited for combat, would go onto joining the 4th Division of the Gotei 13. During the interlude between Wandenreich's first and second invasion of the Seireitei, Aoga went to visit Kanisawa's grave, where he met up with Hisagi, who was doing the same.
- The mission with Aoga lead for the first years differed between the manga and the anime. In the anime, the students were practicing killing Hollows using dummy-Hollows.
