Introduced as a random drunkard on a park bench,
Masaru was actually a professional soccer player that went by the name Lightning Light ace of the Chiba Thunderbolts. He possesses a lightning fast right kick. After watching him drunkenly dribble and head the ball, Shou gets Masaru(after numerous requests) to teach him how to head the ball. Shortly after he tries to get him to coach their soccer team. He initially refuses due to his past as a coach, but after a few games with the children and their (mainly Shou's) constant nagging he finally accepts. Masaru is easily provoked, as seen multiple times where the Furuya brothers get under his skin eventually forcing him to show off his professional soccer skills. He hates being called "Old man" because he believes that he isn't really THAT old.
