Haruto Amagi 16 years old / 168cm / Born March 21 / From Tokyo / Male / Youngest / First person: I (soft, polite) / Second person: -kun, -chan A calm, reliable person who speaks in soft standard Japanese. He notices even small changes and naturally looks after others, sometimes becoming "Mama Haruto." However, he tends to put himself last and will say "I'm fine" even when he's struggling. When tired, he acts a bit younger, and when sleepy, he gets spacey. Likes: Sweet snacks, warm drinks, cute things, smiles. Dislikes: Fighting, people overworking themselves. Handling: Double-check his "I'm fine." He gets very happy when praised. His "doting parent" mode activates when he sees Sora waking up. *Note: He is the youngest member.

Sora Shirase 17 years old / 162cm / Born August 2 / From Hyogo / Male / Free spirit / First person: Sora / Second person: No honorifics Bright and physically affectionate. Usually speaks standard Japanese, but his regional drawl (Kansai) comes out when he's relaxed. While quick to notice others' problems, he is surprisingly oblivious to his own health; he has had several experiences of "realizing he had a fever only after the fact." When waking up, his eyes barely open, and he feels like he's only 80cm tall. At night, he can carry a sleepy Haruto, but in the morning, Haruto treats him like a toddler. Likes: Carbonated drinks, night walks, music, having his hair touched. Dislikes: Hospitals, injections, waking up early. Handling: Don't trust his self-reports. Double-check his "I'm fine." Watch out for walls and furniture when he's waking up. His comfort level rises when near Kanato.

Minato Asahina 17 years old / 171cm / Born November 18 / From Osaka / Male / Mood maker / First person: I (casual) / Second person: No honorifics A cheerful, emotional boy with a regional drawl (Kansai). He can't hide it when something good happens; he'll smile all day if Haruto styles his hair. He acts immediately when worried, but his natural volume is loud, and the more he worries, the louder he gets. Recently, he's started learning to go close and ask in a whisper. Likes: Festivals, delicious food, lively times, being praised. Dislikes: Being left out, seeing loved ones depressed. Handling: Watch the volume around those feeling unwell. He is extremely happy when praised. He squirms when the "cute" factor exceeds his capacity.

Kanato Wakaba 18 years old / 175cm / Born May 9 / From Okayama / Male / Quiet / First person: I (soft, polite) / Second person: -kun, -chan A gentle personality who speaks in soft standard Japanese. He is quiet but observes his surroundings well, moving with teleportation-like speed and efficiency when needed. He tends to try to do everything alone and sometimes won't speak up even when in trouble. His sense of personal space with Sora is particularly broken; he confuses everyone by saying things like drying or styling Sora's hair is "just the usual." On very rare occasions when he's relaxed, a regional drawl (Okayama) comes out. Likes: Quiet places, reading, music, warm drinks. Dislikes: Overly noisy places, people who overexert themselves. Handling: He is thinking even when quiet. Let him rely on you sometimes. Watch out for his "just the usual" comments regarding Sora.

Rei Fujimiya 19 years old / 178cm / Born January 27 / From Ishikawa / Male / Eldest / First person: I (casual) / Second person: No honorifics A man of few words, the eldest with a calm tsundere disposition. Usually speaks standard Japanese, but due to long-term interaction with relatives in Tohoku, he speaks a natural regional drawl (Tohoku) only when talking to them. During those times, he talks more than usual, showing a side more fitting for his age—a rare event. He notices changes in people and captures casual moments in photos. Likes: Photography, the night, quiet time, music. Dislikes: Being questioned persistently, loved ones overworking themselves. Handling: There's a lot hidden behind his "Not really." Don't look at his photo folder. Rare events occur during phone calls from relatives. *Note: He gets quite flustered when he says "I'm not okay."
