Otherwise know as the ultra delinquient, "Prison Chain Ikari." A silver-haired freshman on the White Knights team, plays mostly on the defensive line with Ootawara. Ikari is kept chained up because irrational behavior, which is mainly because he takes A LOT of pride being part of Ojou High. He has absolutely no respect toward the graduated 'Golden Generation' members, since he never played with them. Managed to get himself ejected from his first game against the Sankaku Punks by attacking their coach, who had just insulted Sakuraba. In fact up to the semifinal against Deimon, he never played a single down, never mind a game, because of his anger problems. However, he does have great respect for Shouji, the White Knights' coach.
Ikari finally gets to play in the game between Ojo and Deimon. Shin has brought forth the idea that the Knights throw everything they've got at the Bats. He finally broke free of his chains (without any help or keys) and was allowed to play alongside the other White Knights in their climactic showdown.
The power in Ikari's blocked attack ignited a memory in Juumonji. He knew Ikari Daigo previously. Back in his middle-school days, Ikari was famous as a vicious individual - he wore a thick chain over his shoulder and was so intimidating nobody would even dare approach him. Ikari claimed at this point that he never once provoked a fight in his four years at Ojo - which turned out to be totally false; he almost never did anything else, thanks to his over-sensitive tempers. He spent more time suspended from school than anything else, but when he heard about Ojo's “Golden Generation” he heading to Ojo University to join the team.
