The word yarichin is Japanese slang for someone who is sexually promiscuous or a "playboy." This character is usually confident, manipulative, and uses their position to tease or seduce the student.
One of the most striking aspects of Yarichin Kateikyoushi is its portrayal of the relationships between the tutor, Shin, and his students. As a tutor, Shin occupies a position of authority and trust, which inherently creates an imbalance of power. The series takes this dynamic as a starting point to examine the ways in which power can be both wielded and negotiated. yarichin kateikyoushi
