Shuichi Saihara is a student in the Ultimate Academy for Gifted Juveniles and a participant of the Killing School Semester featured in Danganronpa V3: Killing Harmony. His title is the Ultimate Detective. Shuichi's parents are a famous actor and a screenwriter, who went overseas for business, which is why Shuichi began to live with his uncle and his wife. While Shuichi claims there isn't any sad story behind it all, his parents are neglectful towards him, and he smiles bitterly whenever he talks about them. To show his gratitude to his uncle, Shuichi helped him by working as his assistant in his detective agency. While he was only helping out and had no desire to be a detective himself, he learned to be a detective this way.
