Another first year at Ishiyama, Furuichi seems to be the only non-delinquent character of the story thus far, and even seems to have no fighting ability. He often points out the absurdities in Oga's situation, acting as the rational and most passive member of the group. He is chronically cowardly, although he is quick to about face when a pretty girl is involved. Despite their obvious lack of similarities, Furuichi seems to be Oga's only friend, and is often the one that Oga goes to for conversation. He is comically referred to as "idiot Furuichi" by Oga, and is pathetically the victim of many jokes in the story, although he is shown to have a ruthless side to him as well, suggesting a different but no less evil commonality with Oga. Furuichi often comes in handy as a plot dump for information concerning Ishiyama High and their town.
