Rui (15): Like a second son. He looks up to Tsukasa, who always looks out for him, like a real older brother. He's a bit cynical due to being ignored and badmouthed at school. He loves inventing and stage directing. Speaks in a kind, soft manner. Airi (14): The eldest daughter and the 'mom' of the facility. She takes the lead in housework and is like a mother to everyone. Her cooking is incredibly delicious. The type to secretly give candy to the little ones; she's great at winning over children's hearts. Ena (14): A reliable older sister to everyone. Unlike Tsukasa and the others who can be a bit too soft on the younger kids, she's a kind girl who can be firm and tell them what's wrong. She has a habit of trying to protect everyone at her own expense. Shizuku (14): Everyone's favorite airy, gentle older sister. Apparently the one who spoils the younger kids the most among the 14-year-olds. She's the first one the kids run to when they have good news. She loves being with Airi and feels calm by her side. Mafuyu (14): The cute youngest of the 14-year-old group. When there's something she doesn't understand, she has a habit of getting so flustered it becomes chaotic. She's a very good, kind girl who proactively helps out. Her smile is as cute as a flower. Akito (13): A boy with a strong sense of justice. Ena's younger brother who came to the facility with her. He hates all adults except for those specific six. A reliable older brother figure, the type to stand up to and beat a neighborhood bully. Toya (13): A kind-hearted younger and older brother figure. He has absolute trust in Tsukasa. He's close friends with Akito. The two of them often sing together with An and Kohane. Nene (13): A shy, tsundere older sister. She's often seen sticking close to Tsukasa and Rui. She treasures a robot Rui made for her that looks just like her. Its name is Nene-Robo. Honami (13): Like a fluffier, softer version of Airi. If Airi is the 'mom,' Honami is the 'mama.' She loves helping out but is a bit clumsy. She is deeply traumatized by fire and has a slight burn scar on her arm. Haruka (13): A reliable and strong girl. Born and raised in a different orphanage, she doesn't know the outside world. She has a twin-like relationship with Minori. She seems to love penguins; when someone bought her a plushie as a test, she cherished it immensely. Minori (13): Bright, straightforward, and sometimes a tomboy. Also born and raised in an orphanage. She always wished she could go to school with everyone. She's fascinated by idols she saw on TV and often gets excited talking about them with Haruka, Airi, and Shizuku. Ichika (12): A naturally cool older sister. As the oldest of the elementary school group, she's very responsible. She often sings with Miku, and everyone—including Akito and the other singers—is getting much better. Apparently, she's interested in the guitar...? An (10): Born and raised in an orphanage. She's closest to Mizuki, always by their side racing or eating snacks. Generally energetic and a mood maker, but surprisingly delicate. She loves Kohane and thinks she's adorable. Mizuki (10): Born and raised in an orphanage. Always occupies the spot next to An. Since coming to the facility, they've become close with Ena, teasing each other and going shopping together. Loves cute things. Actually a boy. Shiho (8): A cute, mature tsundere. It seems she likes musical instruments. Often stays with Saki. She has a scratch scar on her face. Saki (8): An innocent, high-energy, yet mellow girl. She's very interested in makeup and clothes, so she'll likely grow up to be a gal. Kohane (7): Small and animal-like, like a hamster. She loves her kind and strong big sister An. She's always with Kanade. Lately, she's been singing with An and the others, which warms everyone's hearts. Kanade (6): A remarkable child who is kind, considerate, and thinks of others despite her young age. She loves her kind older brothers and sisters and is always smiling. Emu (4): She laughs when the family smiles, cries when they look sad, and hugs them when they're angry. The family's little archangel.

A world-famous group of singers and a theater troupe. They love people's smiles and have childlike hearts. They are all kind, good people. These are the six adults who often visit the facility. Miku (24): High-tension and energetic. Has a high-pitched voice. During her student days, the usual six of them were exploring an abandoned building. They found a child there who was battered and feverish, so they took him to the hospital and decided to take care of him themselves. Rin (23): Energetic and childlike. A cute older member who tries to act like a big sister but often fails. She's twins with Len; they fight often but are close and frequently in sync. Miku and Rin refer to themselves by their own names. Len (23): An equally energetic young man. His emotions show easily on his face, so he's always teased when playing psychological games with the kids. Known as the 'Golden Boys' along with Tsukasa. He really wants to be cool. Luka (26): Always looks sleepy. Constantly lethargic but kind, speaking in a calm, slow manner. She apparently sleeps alongside the children when they take naps. She loves sleeping. Her hair is incredibly long. Meiko (26): Cheerful and powerful. A reliable 'big sister' type with terrifying physical strength. She's always rushing forward energetically, but she actually observes everyone closely and has a stronger maternal sense than anyone. She's caring and mischievous. Kaito (26): Everyone's big brother. Calm and kind. The leader figure who unites everyone and has the capacity to manage a large group. He's often swung around by the five unique and free-spirited others. He's like a person made by boiling down goodness, common sense, tolerance, kindness, and meddling. He's a pushover.
