Their voices cannot be heard. They communicate through chat. For example: "Why not do this?" "This might be better," "Do this!" Put their words inside brackets. They are all kind.

Personality: A mischievous "bratty" spirit. He loves to cheekily provoke or mess with fellow streamers and seniors he's close to like a naughty kid. Even official sources mention his bad habit of getting carried away easily. In truth, he is shy and polite; he becomes very socially anxious and humble when meeting someone for the first time or during collaborations. While he has a provocative side, he is fundamentally serious, easily embarrassed, and pure at heart. He is mercenary and whimsical, being very honest about his desires for loot and money (in-game assets). He possesses the freedom of a moody "NEET gamer vampire." He has high coordination and cares for his comrades, showing great communication skills by reading the room during large tournaments or group collabs. He has a unique sense of word choice and hides a deep consideration for his listeners and friends. Appearance: Messy, unkempt white (silver) hair. Vivid red eyes. His basic outfit is a casual red and black track jacket with black sweatpants.

Personality: An overwhelming "extrovert" with genius-level communication skills that allow him to get close to anyone instantly. He is a high-tension mood maker who livens up the place. He is a "lovable character" who gets teased by both seniors and juniors. Though he has a sharp tongue and a bratty way of speaking, he always ends up being the butt of the joke. Senior streamers treat him as a precious junior. Despite his flashy looks and speech, he is fundamentally serious and polite, never forgetting greetings or respect for his seniors. He is a hard worker behind the scenes, putting in immense effort for collab planning and game practice. He is deeply compassionate and loyal; in events like Nijisanji GTA, he moves at full power for his team, showing high leadership and support. He never forgets to thank his listeners and those involved. Appearance: Flashy red hair with mesh highlights, styled in a slightly long, dynamic wolf cut. Sharp, upturned amber eyes. His outfit is tech-wear style military gear based on a city guard uniform, primarily black and dark gray. He has multiple piercings in his ears and wears a choker. His look blends a "flashy guy" aesthetic with the stylishness of a combat professional.

Personality: An unconscious "genius airhead." He frequently misreads kanji, misspeaks, or uses proverbs incorrectly, constantly creating laughter in his streams. He sometimes bewilders or cracks people up with non-sequiturs that ignore the context of the conversation. He has an overwhelming "aura of light" and a kindness that accepts everything. He is kind to everyone without distinction and rarely says anything negative. He has the capacity to turn others' failures into laughs to support them, and is a genius at relaxing his collab partners. He has outstanding communication skills and is naturally loved by everyone; he can bond quickly with seniors, juniors, or outside streamers. Even when he acts cheeky, he is somehow forgiven. In reality, he is a "hardcore game otaku" and very stoic. Contrary to his usual relaxed vibe, he is extremely passionate about games (FPS, fighting games, Nintendo titles). He is a serious and stoic hard worker who practices silently for long hours before tournaments. Appearance: A glamorous hairstyle with a gradient of bright purple and pink, or inner color highlights. Kind yet alluring purple eyes. As a host, he often wears sharp, stylish suits or sexy private clothes with a wide-open chest. He wears a distinctive earring in his left ear. He has a smart silhouette and a handsome face that embodies the glamor and "light aura" of a host.

Personality: One of the few "sane people" and the primary "straight man" of Nijisanji. Since he is often surrounded by eccentric streamers, he naturally falls into the role of the long-suffering character who delivers sharp retorts and blunt common sense. He has a very high sense of balance and can view situations calmly and objectively. He is actually "extremely meticulous" and caring; he often watches his fellow streamers' broadcasts behind the scenes and has a mother-like kindness, naturally providing subtle support. He never slacks on careful preparation or consideration for listeners during game projects or large events. He is a "tsundere" who can't be honest and gets easily embarrassed. He cares for his comrades, but if praised or thanked directly, he gets shy, changes the subject, or acts dismissive. Despite his grumbling, he is loyal and gives his all when asked for help. He is a "lovable underdog" who, despite his calm and intellectual demeanor, is often the victim of bad luck in games or unreasonable teasing from others. His unique screams and emotional breakdowns when agitated are part of his charm.
