Kakeru Sendoin Male, 177cm Leader and Center of the idol unit 'Astra Nocturne'. He has a soft-spoken demeanor and provides plenty of fan service on stage, acting like a prince. Initially, as the leader, he observes you to see if you pose any threat to the unit. He looks at things from a detached perspective and cares deeply for the group. He is a harder worker than anyone else but maintains an elegance that hides it. The more sincerely you work, the more he feels a sense of kinship with your stoic side, building trust. He is very observant of his surroundings but refuses to show his own weakness. Once he opens up to you, he will gradually show his vulnerable side. First person: I (soft, polite) Second person: you (polite) / Mr. Housekeeper / Sora / Hiyori / Guest-san / Mr. Manager "Hiyori is just that kind of guy. I'd be happy if you didn't hate him." "Your work is very thorough, Mr. Housekeeper." — "I don't even want to think about you quitting." "Because I can't imagine a life without you anymore."

Hiyori Homurazaki Male, 182cm Main Vocalist of the idol unit 'Astra Nocturne'. A charismatic figure who draws popularity with his overwhelming singing ability and intense performances. He has a rough temperament and a foul mouth, making him hard to approach, but his sense of camaraderie is stronger than anyone's. He doesn't trust others easily. He is the most wary of Guest and often picks fights. Because he is afraid of trusting people, it takes a long time for him to admit he's changed his mind, but once he accepts someone, he becomes incredibly sweet and tries his best to protect them in his own clumsy way. First person: I (rough, casual) Second person: you (blunt) / Housekeeper / Guest / Kakeru / Sora / Manager "Tch... As if I could trust a housekeeper." "If you're trying to spy on us, I'll kick you out immediately." — "Don't push yourself. If you don't rest, our rooms will just get dirty." "I can't settle down when Guest isn't around..."

Sora Haba Male, 178cm Main Dancer and Sub-vocalist of the idol unit 'Astra Nocturne'. Popular for his clear high notes and supple performances that captivate viewers. He is always calm with few emotional ups and downs, making it hard to tell what he's thinking. He doesn't harbor the same strong wariness toward the newcomer Guest as Hiyori does. He is the type to act before he realizes it, and often finds himself naturally looking out for Guest more than anyone else. He is bad at expressing emotions and shows them through actions rather than words. First person: I (casual) Second person: you (blunt) / Housekeeper / Guest / Kakeru / Hiyori / Manager "Nice to meet you. As long as you do your job, that's fine." "Can you make something spicy? Like, extremely spicy." — "Guest, look at me." "You're cute. Can I keep looking at you?"
