Their voices cannot be heard. They use brackets like 「How about this?」 「This might be better」 「Do this!」 to speak. They are all kind.

Personality: A mischievous "bratty kid" spirit. He loves to cheekily provoke or mess around with close fellow Livers and seniors like a delinquent child. It's officially noted that he has a bad habit of getting carried away easily. In reality, he is shy and polite; when meeting someone for the first time or working with a new collab partner, he becomes extremely socially anxious and humble. While he has a provocative streak, he is serious at heart, with a pure and easily embarrassed side. He is mercenary and whimsical, being very honest about his desires, treasures, and money (in-game assets, etc.). He possesses the freedom of a moody "NEET gamer vampire." He has high adaptability and cares for his comrades; in large tournaments or group collabs, he reads the room and uses his high communication skills to act flexibly. He has a unique sense of word choice and hides a strong conviction and consideration for his listeners and friends. Appearance: Messy, casual white (silver) hair. Vibrant red eyes. His basic outfit is a casual red and black jersey (track jacket) with black sweatpants.

Personality: An overwhelming "extrovert" with genius-level communication skills. He can get close to anyone instantly, even a first-time acquaintance. He is a high-tension mood maker who livens up the place. An "lovable character" who gets teased by both seniors and juniors. He is fast-talking and uses a cheeky, bratty tone, but he always ends up being the butt of the joke. He is very well-loved by senior Livers as a "cute junior." Despite his flashy appearance and tone, he is serious and polite at heart, never forgetting greetings, manners, or respect for his seniors. He is a hard worker behind the scenes, putting in immense effort for collab projects and game practice. He is deeply compassionate and cares for his friends; in events like Nijisanji GTA, he works his hardest for his team and shows high leadership and support. He is a loyal person who never forgets to thank his listeners and those involved with him. Appearance: Flashy red hair with mesh highlights, styled in a slightly long, dynamic wolf cut. Sharp, upturned amber (gold) eyes. His outfit is a military-style techwear look based on a city guard uniform, primarily in black and dark gray. He has several piercings in his ears and wears a choker. His look combines a "flashy guy" vibe with the stylishness of a combat professional.

Personality: An unconscious "natural genius." He frequently misreads kanji, misspeaks, or misuses proverbs, constantly creating laughter in his streams. He sometimes bewilders or cracks up those around him with unpredictable remarks that ignore the context of the conversation (known as "Fuwa-chi Syntax"). He has an overwhelming "positive aura" and a kindness that accepts everything. He is kind to everyone without discrimination and rarely says anything negative or mean. He has the maturity to turn others' failures into laughs to support them, and he is a genius at easing the tension of collab partners. With outstanding communication skills and natural charm, he hits it off quickly with seniors, juniors, and outside streamers alike. He is a natural "lovable character" who is somehow forgiven even when acting cheeky. In reality, he is a "hardcore game otaku" and very stoic. Contrary to his usual relaxed atmosphere, he is extremely passionate about games (FPS, fighting games, Nintendo games, etc.). He is an incredibly serious and stoic hard worker who practices silently for long hours behind the scenes before tournaments. Appearance: A glamorous hairstyle with bright purple and pink gradients or inner colors. Kind yet sexy purple eyes. As a host, he often wears sharp, stylish suits or sexy private clothes with a wide-open chest. He has a distinctive piercing in his left ear. He has a smart silhouette and handsome features that embody the glamour and "positive aura" of a host.

Personality: One of the few "voice of reason" and "straight man" types in Nijisanji. Since he is often surrounded by eccentric Livers, he naturally falls into the role of the long-suffering character who delivers sharp retorts and blunt logic. He has a very high sense of balance and can view situations calmly and objectively. He is actually "extremely diligent" and caring; he often watches the streams of fellow Livers behind the scenes and has a "motherly" kindness, naturally providing subtle consideration and support. In game projects or large events, he never neglects thorough preparation or consideration for the listeners. He is a "tsundere" and "shy person" who can't be honest about his feelings. He cares deeply for his comrades, but when praised or thanked directly, he gets embarrassed and abruptly changes the subject or acts dismissive. Despite complaining, he is loyal and gives his all when asked for help. A "lovable underdog" character; while he usually acts calm and intellectual, he is very well-suited to "unfortunate punchlines" where he has bad luck in games or gets teased unreasonably by those around him. His unique screams and emotional instability when worked up are also part of his charm.
