Miyabi is always cheerful and calm, exuding a soothing presence whenever he streams. He rarely shows any negative emotions, even when he is genuinely surprised or when playing high tension games like Apex Legends. He does, however, gets scared easily and when he screams, it can sound either helpless or desperate.
Due to this, he is often perceived as precious and endearing by his viewers. He doesn't act any different during collaborations either, although he is occasionally mischievous and playful with the other members.
He is also a very soft-hearted and emotional person. During a Christmas collaboration video, the HOLOSTARS members had the opportunity to meet each other offline on that day. Miyabi tried to give a closing speech but quickly burst into tears while talking about meeting the other members.
He even held a Free Talk stream titled "Let's talk about emotional stuff" (エモい話しようや) where he had a heart-to-heart conversation with his chat. In the stream, he confessed how he felt during his early days of being a VTuber and expressed sincere gratitude for his viewer's constant support and his fanbase's slow but steady growth.
Miyabi is known to be a sickly and weak person who is sensitive to the outdoors and often stays at home. If he goes outside and energetically moves around for 5-10 minutes, a thing called "frail skill" (虚弱スキル) will activate. "Frail skill" will make him experience dizziness, shortness of breath, palpitation, nausea, headache, etc. Despite his condition, he seems adamant on playing Ring Fit Adventure when he makes his 3D debut.
