Adapting to life at Tokyo's prestigious Lillian Girls' Academy can be difficult, so the school has developed a long tradition of older students "adopting" younger girls and serving as their advisors and confidantes. Even so, shy young Yumi Fukuzawa is startled and flustered when a beautiful and popular upperclassman Yumi has admired, Sachiko Ogasawara, unexpectedly expresses interest in taking Yumi under her wing. Is Sachiko really serious? And if she is, is Yumi ready to be thrust into the spotlight of public scrutiny that comes with becoming the "petite soeur" to one of the student council's inner circle, the Roses? As the gossip and speculation surrounding the nature of their relationship increases, Yumi finds her life and perceptions changing in new and unexpected directions in the complete collection of the anime classic MARIA WATCHES OVER US.
