Kuroki, Koji

黒木浩二

40-yard dash: 5.1 seconds
Kuroki has medium-length dark hair and noticeably longer eyelashes than the other two. He appears to be the most violent, and his usual weapon is a metal bat. When playing defense, Kuroki can sometimes play Linebacker, while the other two stick to the Defensive Line. He seems to be a prodigy at games, whether it is tossing hoops or playing an arcade game. (In the first book's end-of-book character introduction, he is shown firing a Kikôha as he yells "HUH-DOE-KEN!!!") In the arcade, when Deimon does their final prep work for facing Seibu for the first time, Kuroki is shown furiously button-mashing, and a player comments that he is unexpectedly good at video games. Of the three, Kuroki is the most hot-headed and willing to fall back on his street-fighting skills when his lineman skills fail him. Later, as he and the others become more distinguished as individuals, Hiruma gives him his own nickname, "fish mouth."
He is surprisingly gifted musically, as music is one of the few classes he excels in.
