|Maruko "Maria" Himuro|
|Year||3rd (high school)|
She is a serious looking female with short black hair. She wears a green jacket with white blouse and black pants.
Himuro is Marco's inspiration for playing American football, for he became smitten with her in middle school and, in an apparent attempt to woo her, he vowed to show her "the morning sunshine after a victory" by winning the Christmas Bowl. She came to admire his optimism and ambition, and at some time afterward, the two were in a close relationship, though it is unclear how intimate they were. He now calls her by the nickname "Maria", which she dislikes because Himuro is two years Marco's senior, the player realized that his first year in high school would be his only chance to make good on his promise. After witnessing many players injured by Rikiya Gaō's strength, Himuro came to despise Marco's determination to win at any cost, and they grew apart, though she remains with the team.
Kanto Tournament Arc
Himuro approaches Sena and Riku before the Seibu-Hakushū match, and tells them that they should give up midway, because she does not want to see anymore players injured by Gao. While she hates the Dinosaurs' strategy, she points out after Hakushū loses in the Kanto Tournament finals that she stayed with the team because she still admires some of Marco's traits, and has feelings for him in spite of the things he has done and told him that she would quit as manager if she had completely despist Marco's drive to win.
