Daichi Shinigawa is a typical delinquent who wants nothing to do with high school. However, bespectacled Hana Adachi, the class representative, will do anything in her power to make sure Daichi participates in whatever events the school has to offer. If she has to surprise him in the boy's bathroom to get him to go on the school field trip, so be it! Daichi is confused as to why a class rep would care so much about a troublemaker like him; what could be the reason behind her actions?
Yoshikawa Miki was an assistant of Mashima Hiro when he was makin' Groove Adventure Rave, so that's what can see the evident influence that she got from him: The surprised faces, gags and the style of drawing (Macchi looks like Natsu for example).
Natsu, Gray and Erza are like the yankees in Yankee-kun to Megane-chan (Adachi, Shinagawa and Izumi), and there are someone who has common sense (Lucy & Chiba), they are in an Organitation who helps people with troubles (Fairy Tail Guild, and the Student Council).
Both mangakas, likes to draw werid characters (for example, the sun-face of Rave Ichiya, the girlfriends of Nerima or that strange teacher who teachs Shinagawa)Yoshikawa and Mashima are very good friends too, that's why they make Fairy Megane, a crossover of their respective series.
