Taisei Yoshida

吉田大成

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 Ryouma Terasaka and Takuya Muramatsu.

Yoshida is an inconsiderate individual, unmindful to the consequences of his actions. He is willing to resort to any means in order to escape contemptible circumstances. He collaborates with Ryouma and Takuya, and together they pressure others to act according to their bidding.
