Juuji Isoyama is a First Class Ghoul Investigator serving the CCG. He is among the officers deployed for the assault on Akihiro Kanou's underground laboratory, wielding the bikaku quinque known as Shaku.
Isoyama stands tall and keeps his black hair cropped short. Like the rest of his colleagues, he is typically seen in a suit and tie.
The series offers no real window into his temperament, leaving his character largely undefined beyond his professional conduct.

Isoyama joined the raid on Kanou's lab and moved with Special Class Shinohara toward the facility's core. When they came upon Ken Kaneki in his unfinished kakuja state, Isoyama held back rather than engage, aware that he could offer nothing useful against an opponent of that kind and leaving the confrontation to Shinohara.
