Furuichi is a friend of Akiyuki and like Haru, practices martial arts, though it seems that she is much better than him. Unlike Akiyuki, Furuichi is slightly more cynical and serious, though he is playful enough to bet with Haru on whether Akiyuki will be late or not. Furuichi joins the Mainsoul military and demonstrates great skill in fighting Xam'd whilst his relationship with Haru drifts apart. As a result, the reunion of Akiyuki and Haru is interrupted by him, and he declares his intention of killing Akiyuki due to his cold indifference over the identities of Xam'd.
