Summary
Kuroki Koji wears jersey number 52 as a lineman and offensive tackle, standing ready to switch to linebacker on defense while his teammates remain fixed on the defensive line. Born on September 2, he possesses a bench press strength of 85 kg and a 40-yard dash time of 5.1 seconds. Visually, he is distinguished by medium-length dark hair and eyelashes that are noticeably longer than those of the other two main characters. He is characterized as the most violent of the trio, often relying on a metal bat as his weapon of choice and displaying a hot-headed temperament that leads him to revert to street-fighting tactics when his athletic skills are insufficient. Despite this rough exterior, he is a prodigy in various games, excelling at everything from basketball to arcade titles. This talent was highlighted during Deimon’s final preparations against Seibu, where he was observed furiously button-mashing to the surprise of other players. In the introductory character section of the first book, he is depicted unleashing a Kikôha while shouting "HUH-DOE-KEN!!!" Later in the story, Hiruma bestows upon him the nickname "fish mouth" as he and the others establish their individual identities. Surprisingly, Kuroki is also gifted musically, as music is one of the few academic subjects in which he truly excels.
