Koji Sagara  

A second-year student who founded a Pro Wrestling group and later became part of the Executive Council. He joined after Mitsuomi promised his startup would not be destroyed, he'd have a place to practice, and receive funding. His alter ego is Saga Mask, which he believes is his most brutal enforcer persona. Even when wearing it, he won't remove his mask because of personal convictions. He was tasked with punishing Ryuuzaki for losing to Maya Natsume and stopping anyone from escaping during the bowling alley attack. In this fight, he lost to Souichiro but only after being promised a rematch. For three months, he trained in the Japanese Alps before returning to challenge Souichiro again. During their second bout, Souichiro warned him of potential death and then punched him so hard that his entrails exploded. This was an illusion meant to show Saga the difference between their levels.
