Kojima
School: Sakura Middle School
Kojima's a confident kid with bleached blonde hair who rocks the standard school uniform—white shirt, black pants, the works. He's got that show-off energy that kicks in even when things could go sideways, which probably says something about either his courage or his judgment depending on who you ask.
His actual fighting ability is never demonstrated on screen, but the guy clearly carries himself like someone who's been in scraps before. The betting odds on his matchup against Takuya Yamamoto favor him at 4-6, which suggests he's built up enough of a reputation that people are willing to put money on him. Whether that confidence is fully earned or just really convincing is another question entirely.
