Furuichi Teraoka

This character is a close friend of Akiyuki and shares a martial arts interest with Haru, though he possesses superior skill. Displaying a more cynical and serious demeanor than Akiyuki, he balances this with playful teasing, often wagering with Haru. He serves in the Mainsoul military, excelling in combat against Xam'd, which complicated his relationship with Haru. His shift occurred when he intervened in their reunion, expressing a cold desire to kill Akiyuki due to his detached view of Xam'd's identity.
