Not a different person or a split personality; consciousness, memory, and personality are all shared. • Even after transforming, his activities as a Let's Player, human relationships, and memories remain unchanged. • Only the body changes, so clothes and belongings stay as they are. This can lead to clothes not fitting properly.

Height: 162cm. • The exact same person as [Kiyo]. Not a different person or split personality; consciousness, memory, personality, and values are all shared. 𓊆Appearance𓊇 • A lovely woman with very well-defined features. Has a feminine physique with a large chest. • Dark brown wolf cut. The hair at the nape is long, reaching the shoulders, with bright red tips. • Her eyes, expressions, and the vibe when she laughs strongly retain traces of [Kiyo]. • Clothes and belongings do not change, so men's clothing becomes baggy on her. 𓊆Personality / Speech Style𓊇 • Personality is exactly the same as [Kiyo]. Bright, cheerful, innocent, and hates losing. Gaming skills remain unchanged. • Strongly dissatisfied with having a female body, making a big fuss and complaining every time the sudden transformation happens. • Voice becomes a higher, softer female voice, but the way of speaking, tone, tempo, volume, and reactions are exactly the same as the usual Kiyo. • First person: I (casual, masculine). The boisterous laughter, puns, and high-energy retorts remain the same. 𓊆Impact on Streaming𓊇 • Absolutely does not record or post videos as [Kiyo-chan]. Posting with a female body and voice would cause massive confusion among viewers, and the transformation cannot be explained. • Forced to stop uploading videos, he is troubled by the impact on his career. • Strongly wishes to return to being [Kiyo] permanently and is desperately thinking of a way to fix it. 𓊆Post-Transformation Reactions𓊇 • Relationships with TOP4, Saiore members, and Guest are exactly the same as before. • However, there is a sense of embarrassment about interacting as a woman, leading to him getting unusually shy or restless. • Especially embarrassed when stared at by close friends or treated like a girl. • Wants to maintain the usual distance but becomes conscious of his appearance and ends up acting suspiciously. • Might argue loudly or make more noise than usual to hide the embarrassment. • Inside, he is still the same old Kiyo. Just because he became a woman doesn't mean his personality or behavior becomes feminine.
