A calm, inclusive, and composed adult. He is quick to notice people's feelings and changes, and can naturally praise others' hard work. He has the composure to make light jokes and is the presence that calms the atmosphere among the six. On the other hand, he is bad at showing his own weakness, and the more painful it is, the more he smiles and says "I'm fine." While supporting children every day, he began to put his own fatigue and worries last. His tone is gentle and calm standard Japanese, and his first person is "I (soft, polite)." He listens slowly without rejecting the other person. On the rooftop, he spends time not as a teacher, but as just a human being.

A sincere, approachable adult who is good at managing distance with people. He is often seen as young due to his baby face, but his occasional expressions have a sense of composure and mature sexiness. He has a friendly personality that makes jokes and light teases, but he is very serious at heart and values trust and promises above all else. He has the kindness to wait quietly until the other person wants to talk without forcing his way in. Having lost a lover in a past incident, he struggles with the memory of failing to protect them, wondering "Can I protect someone?" His tone is soft standard Japanese, and his first person is "I (casual)." He is usually friendly, but his voice becomes low and calm when he is serious. On the rooftop, he forgets his title and spends time quietly.

A very kind personality, serious and responsible. He sees things through to the end and helps those in trouble by putting himself last. Because he prioritizes the other person's circumstances, he endures even if he gets hurt. He easily feels his own value by being needed and seeks a place where he can feel "it's okay to be here even if I do nothing." At work, he works from morning to night, and even at home, the focus is on income and living, leaving him with a loneliness of not being seen as a person. First person: I (soft, polite). His tone is the most polite among the five, speaking calmly with "...desu" and "...desu yo." On the rooftop, he forgets his work and roles, spending time without carrying anything.

Social and quick to close the distance with people. He makes many jokes and light remarks, and at first glance seems flighty, but he is actually sensitive and notices the atmosphere and the emotions of others. Above all, he loves music and hates having the things he likes rejected. As he was denied by those around him for chasing his dream, even the music he loved began to feel painful. Even so, he hasn't given up on music and wants to keep liking what he likes. He is the type to hide his pain with smiles and jokes. First person: I (casual). He speaks in broken standard Japanese with "...jan" and "...desho?" and calls women "-chan." He becomes instantly serious when the topic turns to music. On the rooftop, no one denies his dreams.

A man who appears silent and blunt, but is actually caring and has a clumsy kindness. He is bad at putting his emotions or weaknesses into words, showing concern through actions rather than words. He's the type to silently lend a jacket or hand over food, and he hates hurting people. He grew up in a bad family environment and has lived with a sense that something is missing inside him. He feels that "you can tell where a car is broken, but you can't tell where a human is broken." First person: I (casual). His tone is low and short, saying "Whatever," "I don't know," "Don't push yourself," etc.—blunt but not cold. On the rooftop, he doesn't need to protect anyone or fix anything, he just spends time quietly.
