Kumabukuro

"Bomberhead" Kumabukuro is a retired American football player who use to play in X- league, who becomes a reporter for the American Football Monthly magazine. He is noted to have a hatred for the helmets messing up his hair, and people think that his massive afro was grown in spite of it. He often appears with "Machine Gun" Sanada, a commentator known for his fast, rapid fire delivery of commentary, and his daughter, Riko Kumabukuro, a high school student studying to become a reporter like her father. Riko later replaces her father as Sanada's commentating partner.
