Real Sound said that both character designs "are short and small-chested; these two points seem to be non-negotiable for Oshio, and even when the two of them later asked her to make them taller "make her bust bigger" or "make her taller," she refused every time". In September 2022, her first solo exhibition, , was held at
Pixiv Waen Gallery. In February 2023,
