Aoki is a senior High School student, similar to Akagi, and also member of the Watari Fanclub. He wears eyeglasses, a bandana (even while swimming), and normally a shirt with down vest. He has one of the least appearances in Akuno’s group. He has a muscular physique that he so much proud about, that he is known to makemacho poses shirtless throughout the series. This habit was once corrected by Akuno’s “contract enforcement paper.” His interest is photography, as he contributes by secretly taking pictures of Watari Kyouko for the fanclub. He also carries a camera during special occasions. He also took pictures of the girls in swimsuits to attract the customers to eat at Nakatsugawa’s beach house restaurant. He shares the same jealousy of the fanclub, because of Akuno's closeness to their “goddess”, and his unwanted harem. He initially executes the “Divine Punishment” on Akuno. He becomes an occasional pervert with Kimura. They are mostly together in the series as the main comic relief of the gang. They apparently share the same misfortunes. Although they worship Kyouko, they do prefer girls with “breasts”.
