Sansha Sanyou

Futaba Odagiri is the energetic transfer student who befriends Teru Hayama, the class president who is meaner than she looks, and Youko Nishikawa, a former rich girl who still acts like a princess. Three very different girls who only share one thing: the kanji for leaf in their names. Balancing school and life is hard enough, but what about dealing with clashing personalities on top of it all?
