Mana Ashida as Kirara Sasaki, nicknamed "Post" (ポスト), a
tomboyish, headstrong, wise, and perceptive 9-year-old girl and one of the first children at the orphanage. She is the leader out of all the children. Her nickname comes from her being abandoned at a
baby post. She also despises her real name due to its girly-sounding nature. Since she was raised by Maou, she is the most similar to him. Despite her tough personality, she has a soft spot when it comes to her friends. (For example, fighting off Piami's bullies, breaking into an apartment to save Pachi, helping Otsubone to leave her abusive home, and staying loyal to Locker when he made a mistake). •
Rio Suzuki as Maki Watanabe, (later Maki Kawashima), nicknamed "Donki" (ドンキ), A naïve, and somewhat spoiled, 9-year-old girl who was abandoned at the orphanage by her mother. Her nickname comes from the
Japanese word
Donki, (meaning blunt weapon), that her mother used in her assault towards her boyfriend. She rejects her nickname at first, as she does not want to live at the orphanage. However, she later accepts the name when she realizes her mother will not be back anytime soon. •
Hiyori Sakurada as Naomi Toba, nicknamed "Piami" (ピア美), an elegant, girly, and romantic 9-year-old girl. She is talented at the
piano, hence her nickname Piami, (a combination of her given name Naomi and the word piano). •
Konomi Watanabe as Yuiko Tōjō, nicknamed "Bombi" (ボンビ), a bubbly, excitable, and childlike 9-year-old girl with a big imagination. Her Dream is to be adopted by
Angelina Jolie and
Brad Pitt, due to their several international adoptions. Her nickname comes from a combination of the words
Bimbō, a
Japanese word for
poverty, and Disney's
Bambi . Her parents died in a natural disaster, but their bodies were never found, hence, she secretly believes her real parents are poor and will come back to get her when they have enough money. •
Shohei Miura as Locker (ロッカー), A good-hearted, quiet, 21-year-old man who was the first ever child at the orphanage. He was never adopted, so he continued to work as a staff member and their
chef. At first, he suffered from
Selective mutism, but later found his voice. Despite his own trauma, he is one of the most kind-hearted persons at the orphanage. He also seems closest to Post out of all the children. •
Suzuka Ohgo as Otsubone (オツボネ), an emotional, naïve, and somewhat desperate 17-year-old-girl who still has hope of being adopted, despite being the
age of majority, and will be forced to move out of the orphanage. She suffers from
heterochromia, caused by a piece of broken beer bottle thrown at her by her mother, and wears a patch over her right eye. Her previous nickname was
Usa-Tan (a combination of the
Japanese word
Usagi, meaning
rabbit, and the
Japanese honorific -tan, which is used to sound cute). Her nickname comes from the
Japanese slang word
Otsubone, meaning an older woman who has been stuck in the same working position for several years. She often goes to Post for advice on her situation. •
