Ashita, Mama ga Inai

There are over 600 orphanages across the nation, housing approximately 30,000 children. Most of these children had been abused by their parents. Maki was placed into the orphanage "Kogamo no Ie", after her mother, Ryoka, was arrested and jailed. There she was handed over to the care of Kana, and also Sasaki, the eccentric caretaker of the home. Under Sasaki's management, the home is a calm and safe haven from all the madness of the real world.

At the home, Maki befriends three other little girls, who all go by their nicknames instead of their real names: Piama, Bombi, and Post.
