The Reason Behind Aoyama-kun's Choice
Today is the match against the high-ranking Kuraishi High School. In order to break through their ironclad defense, Zaizen's performance as the forward need to be stellar! However, he is the one whose head doesn't seem to be quite in the game. The reason being that Aoyama-kun is being actively scouted for the U16 team! On top of that, today is supposedly the day an important family member passed away. Aoyama-kun might quit the club! This might be the last match Fujimi High School's soccer club plays with this team!

Clean Freak! Aoyama kun
Aoyama, the handsome young soccer genius that's a representative of Japan. His play style is "cleanliness." He doesn't tackle and doesn't head the ball. If he's doing a throw-in, he'll only do it if he's wearing gloves.
