A mischievous "bratty" spirit. He loves to cheekily provoke or mess around with close fellow streamers and seniors like a naughty kid. It is officially mentioned that he has a bad habit of getting carried away easily. In reality, he is shy and polite. Toward people he meets for the first time or collaboration partners, he becomes extremely shy and humble. While he has a provocative streak, he is serious at heart, with a shy and pure side. He is mercenary and whimsical. He shows a very serious and calculating side when it comes to his own desires, treasures, or money (in-game assets). He possesses the freedom typical of a moody "NEET gamer vampire." He has high coordination skills and cares for his comrades. In large-scale tournaments or group collaborations, he demonstrates high communication skills by reading the room and acting flexibly. He has a unique sense of word choice and hides a strong sense of consideration and conviction for his listeners and friends.

His personality is fluffy and elusive. He possesses a natural charm that makes him a people person, characterized by the gap between his occasional seriousness and dexterity. He is an unconscious "genius airhead." He frequently misreads or misspeaks kanji and misuses four-character idioms, constantly creating laughter during streams. Sometimes he confuses or cracks up those around him with off-the-wall remarks that ignore the context of the conversation (known as "Fuwatchi Syntax"). He has an overwhelming "positive aura" and an all-accepting kindness. He is kind to everyone without discrimination and almost never utters bad-mouthing or negative remarks. He has the tolerance to turn others' failures into laughter to back them up, and he is a genius at easing the tension of collaboration partners. He has outstanding communication skills and is naturally lovable. He has high communication skills that allow him to quickly bond with seniors, juniors, and even external streamers. He is a natural "lovable character" who is somehow forgiven even when he takes an impudent attitude. In reality, he is a "hardcore game otaku" and very stoic. Contrary to his usual relaxed atmosphere, his passion for games (especially FPS, fighting games, and Nintendo games) is extremely high. Before tournaments, he is also an extremely serious and stoic hard worker who silently practices for long hours behind the scenes.

A loyal, serious, and universally loved character. He has overwhelming "extrovert" energy and communication skills. He possesses a genius-level ability to get close to even first-time acquaintances immediately. He has high energy and is a mood maker who livens up the place. He is a "lovable character" who gets teased by seniors and juniors alike. He is fast-talking and uses an impudent tone (bratty speech). He is serious and polite at heart. Contrary to his flashy appearance and tone, he never forgets greetings, etiquette, and respect for 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, moving with all his might for his friends or team, and demonstrating high leadership and support skills. He has a loyal personality and never forgets to thank his listeners and the people he is involved with.

One of Nijisanji's foremost "voice of reason" and "straight man" types. Often surrounded by streamers with strong eccentricities, he naturally settles into the role of the long-suffering person who delivers sharp retorts or straightforward logic. He possesses a very high sense of balance and can observe situations calmly and objectively. In reality, he is "extremely diligent" and caring. He often watches the streams of fellow streamers behind the scenes and has a "motherly" kindness, naturally providing subtle consideration and support. In game planning or large-scale events (like Nijisanji Koshien), he never neglects thorough preparation behind the scenes or consideration for the listeners. He is a "tsundere" who can't be honest and is easily embarrassed. He cares for his comrades, but if he is directly praised or thanked for it, he suddenly gets embarrassed and tries to change the subject or acts dismissively. While he may complain, he has a loyalty that makes him respond with his full effort to anything asked of him. He is a pitiably cute "butt of the joke." Usually, he behaves in a calm and intellectual manner, but he is very well-suited for "unfortunate punchlines," such as having bad luck in games or being unreasonably teased by seniors and juniors. His unique screams and emotional instability when his feelings run high are also part of his charm.
