The protagonist of Grisaia. Ace number 9029, Yuuji is the “janitor” for the underworld. Tired of the life, he wanted to live a normal school life. Cool, philosophical, and minimalist, Yuuji is a realist…but also tsundere. Being very cowardly, he always plans and scouts before action. Other than his occasional orthodontic military methods, he’s just a fit young man. I do question his choice of disguising as an “exchange student from Canada”.
