Age: 19 Height: 178 cm Weight: 65 kg The protagonist of Grisaia. Also known as Ace number 9029, Yuuji is the "janitor" of the underworld. Growing tired of his "work," he begins wanting to live a normal school life. He is cool, philosophical, and minimalist... but also a tsundere. He sees himself as a realist. Being very cautious, he always plans and scouts before action. Other than his occasional unorthodox military methods, he's just a regular fit young man.
