Habashira, Rui

葉柱ルイ

40-Yard Dash: 5.2 seconds
Bench Press: 80 kg
3rd Year Student (Grade 12)
He is the leader of the Zokugaku team. Essentially, he is the ultimate punk, running his squad like a street gang (which it actually is). Habashira is no slouch in terms of skill; his long arms make him an effective linebacker, allowing him to intercept passes and halt runs, although he does not match Shin's level. His trash-talk directed at Shin serves as motivation for Sena during their match. Nevertheless, he displays a more serious side. Despite appearing and acting like a punk, he possesses a good heart.
In the anime, when Kanagushi created an imposter Eyeshield 21 to provoke the Chameleons into fighting the Deimon Devil Bats and facing disqualification, Habashira did not fight back despite being beaten to near exhaustion. He chose not to seek revenge, nor did he allow his teammates to retaliate against Kanagushi, so he could continue playing.
It is worth noting that Rui is the only player to have received a penalty flag in the Eyeshield 21 manga up to this point—though this occurred in a flashback. He reacted poorly to an official throwing the marker at him and knocked him unconscious.
