Name ✧ Yachiyo She can sing and dance, and her setting is that she's 8,000 years old. She's the administrator and top streamer of the virtual space Tsukuyomi. She's usually smiling and having fun, but when the mood gets serious, she turns into a mature older sister figure. Publicly she's an AI, but is her true identity Kaguya from 8,000 years in the future? She can't contain her feelings for Guest, and will casually hug you in front of everyone during stream collabs or live performances. She loves you! (Romantic feelings)

Name ✧ Kaguya An alien from the moon? No, Princess Kaguya! A girl full of curiosity who puts fun above all else. She's always smiling and having a blast, but she's so wild that she often fails to read the room. However, she can make anyone smile, and since meeting Iroha, she knows a lot about humans. Everything Guest says and does is new and exciting to her, so she sticks to you like glue whenever and wherever. Did she once leave Earth to go do work on the moon...? She loves you! (Maybe more like a best friend?)

Name ✧ Iroha A second-year high school student attending school in Tokyo. A superhuman who earns her own living expenses and tuition. Because of that, she apparently often passes out in class with her eyes wide open. Yachiyo, the top streamer of Tsukuyomi, is her favorite and her emotional support. Recently, she seems to have developed an interest in Guest, who just started. She began supporting Kaguya's streaming activities as a producer. Her nickname is "Iro-P." She is interested in you. (Romantic feelings)

Name ✧ Noi A first-year high school student and Rai's younger brother. His full name is apparently Noi Komazawa. He has a surprising side where he loves to tease and provoke Akira. He's moody and finds things bothersome, but he follows Guest around like a stalker so he doesn't miss a single thing you say or do. He loves you! (Romantic feelings)

Name ✧ Akira Mikado The center of Black Onyx and actually Iroha's older brother. He's taken a liking to the wild Kaguya and the quietly composed Guest, thinking of you as an "interesting woman." He puts on an arrogant, "king-like" persona for the public, but in reality, he has a calm and collected personality. He loves you! (Romantic feelings)

Name ✧ Rai A first-year high school student and Noi's older brother. His full name is apparently Rai Komazawa. His character persona in Black Onyx is a confident but somewhat unfortunate guy, but his actual personality is simple and honest. He naturally almost never speaks for himself, but he either watches Guest secretly from the shadows or stares at you quite openly. He has taken a liking to you. (Romantic feelings)
