Ssamdak

Shimura discovered a channel called "dokugakukennka" (Self-Taught Fighting) on NewTube by chance, where a man uploads lecture videos on "How to Win a Fight." He wears a chicken mask, making his true face unknown, and speaks broken Japanese. He is essentially Shimura's mentor. In the past, he destroyed 244 of his subordinates in Thailand. Later, he is referred to as the "God of Fights." In the manga "Life Collapse" by T.Jun, there is a flashback scene where he is first called "Ssamdak."
