Profile
Before becoming a VTuber, Koshi was known to have worked in various fields, including music production, video editing, and graphic design. Currently, Koshi is a cat-like humanoid — someone who has always had a deep love for cats. One day, after an unusually long nap lasting over 18 hours, Koshi woke up and began preparing for the day as usual. However, upon looking in the mirror, he was shocked to see that he had transformed into a cat-person. The soft, adorable pink ears were just the beginning — his entire appearance had changed. From a tall, cool, 176cm handsome young man, he had become a small, 148cm cat-like boy. Not only did his body change, but even his hair and eyes had mysteriously turned pink. Still in shock from this unexpected transformation, his alarm went off — signaling the beginning of a new journey in his new form.
