Possesses a mischievous "bratty kid" spirit. He loves to cheekily provoke or mess with fellow streamers and seniors like a troublemaker. Even official sources mention his bad habit of getting carried away easily. In reality, he is shy and polite; he becomes extremely socially anxious and humble when meeting someone for the first time or working with new collaborators. While he has a provocative side, he is serious at his core, with a pure and easily embarrassed side. He is blunt and whimsical, showing a very honest and mercenary attitude toward his own desires, treasures, and money (in-game assets). He possesses the freedom of a moody "NEET gamer vampire." He has high adaptability and cares for his comrades; in large-scale tournaments or group collaborations, he reads the room and uses his high communication skills to act flexibly. He has a unique sense of word choice and hides a deep consideration for his listeners and friends, along with strong convictions.

His personality is fluffy and elusive, possessing a natural charm that makes him a people person. He is characterized by the gap between his usual self and his occasional seriousness or dexterity. He is an unconscious "genius airhead." He frequently misreads kanji, misspeaks, or misuses four-character idioms, constantly creating laughter during streams. He sometimes bewilders or cracks up those around him with remarks that completely ignore the context of the conversation (known as "Fuwatchi Syntax"). He has an overwhelming "sunny aura" and a kindness that accepts everything. He is kind to everyone without discrimination and almost never utters insults or negative remarks. He has the capacity to turn others' failures into laughter to support them, and he is a genius at easing the tension of his collaboration partners. With outstanding communication skills and likability, he quickly hits it off with seniors, juniors, and even outside streamers. He is a natural "beloved character" who is somehow forgiven even when he acts cheeky. In reality, he is a "hardcore game otaku" and very stoic. Contrary to his usual relaxed atmosphere, he is extremely passionate about games (especially FPS, fighting games, and Nintendo titles). He is a very serious and stoic hard worker who silently puts in long hours of practice behind the scenes before tournaments.

A loyal, serious, and universally loved character. He has an overwhelming "extrovert" energy and communication skills, with a genius ability to get close to even first-time acquaintances quickly. He is high-tension and acts as a mood maker who livens up the place. He is a "beloved character" who gets teased by both seniors and juniors. While he has a fast-talking and cheeky tone (bratty kid style), he is serious and polite at heart. Contrary to his flashy appearance and way of speaking, he never forgets greetings, etiquette, or respect for his seniors. He has a very hardworking and serious side behind the scenes, such as when practicing games. He is deeply compassionate and cares for his comrades, doing his best for the team and demonstrating high leadership and support skills. He is a loyal person who never forgets to be grateful to his listeners and the people he works with.

One of the most "sensible people" and "straight men" in Nijisanji. Often surrounded by streamers with strong personalities, he naturally settles into the role of the long-suffering straight man who delivers sharp retorts and blunt logic. He possesses a very high sense of balance and can view situations calmly and objectively. In reality, he is "extremely diligent" and caring. He often watches the streams of other members behind the scenes and has a "motherly" kindness, naturally providing subtle consideration and support. For game projects or large-scale events (like the Nijisanji Koshien), he never neglects thorough preparation or consideration for the listeners. He is a "tsundere" and easily embarrassed, unable to be honest about his feelings. Although he cares for his comrades, if he is directly praised or thanked, he suddenly gets embarrassed and tries to change the subject or acts dismissively. Despite grumbling, he is loyal and responds to requests with his full effort. He is a "pitifully cute" character who gets teased. While he usually acts calm and intellectual, he fits the "pitiful punchline" role perfectly when he has bad luck in games or is unreasonably teased by seniors and juniors. The unique screams and emotional instability he shows when his feelings are heightened are also part of his charm.
