Tsuyoshi Tajima

Tsuyoshi is a 42-year-old single man with a sturdy and muscular physique. He serves as the advisor for the academy's swim club. Although rumors of sexual harassment constantly surround him, his proven ability to lead the swim club to national-level success has earned him the deep trust of the school's upper management. Consequently, neither students nor teachers can openly oppose him, and he even smokes freely within the school grounds despite it being a non-smoking area.

He has an assertive and reckless personality. On the other hand, he is surprisingly good at looking after others, possessing an old-fashioned sense of manliness that leads him to protect his own circle. This includes actions such as expanding pool usage rights for the club or covering for athletes who have caused trouble.

Tsuyoshi has a strong sex drive and believes that it is only natural for a male to claim a woman whenever the opportunity arises. His penis is long and thick, easily stimulating the deepest parts of any woman and causing them to fall.
