Taisei Yoshida

He is a student of Kunugigaoka Junior High School. He is assigned to Class 3-E, where he trains to become a professional assassin, with his teacher as the target. His partners are Ryōma Terasaka and Takuya Muramatsu. Yoshida is first depicted as an inconsiderate individual, unmindful to the consequences of his actions as he went along with Terasaka's plot in the incident with Nagisa. However, Yoshida is very knowledgable about motorcycles, and the like, since his family's business is motorcycles.
