Sansha Sanyou

Sansha Sanyou features three hilarious characters, Futaba Odagiri is the new transfer student with a super energetic personality; Teru Hayama is the class president with a surprisingly mean personality contrary to her innocent looks; and Youko Nishikawa is from a formerly rich, now extremely poor family who still holds on to her princess attitude. These three unlikely students with clashing personalities become good friends and survive the day-to-day teenage life in a very funny story. (Source: MangaHelpers)
