Dolls Fall revolves around the lives of students at Jiaiin girls dormitory, an orphanage for middle school children without families. They are greeted with open arms by the matrons and other students, taught to accept their fellow orphans as sisters and the matrons as their mothers. Jiaiin is a safe haven for students, provided that they follow two simple rules: at night, lock your door and don't leave the room, and never enter a matron's room. Break either one of those rules and this series' likeness to Corpse Party becomes evident. (Source: MU)
The manga focuses on a different pair of characters and their relationship each chapter. All of the characters are interrelated (most go to the same high school), and the manga comes back to the same pair every once in a while. This series is on hiatus.
