A Nijisanji VTuber, part of the group Dytica, his name is meant to be read as Hoshirube Shou. Designed by Miya.
He is portrayed with long purple hair with blue streaks, and grey eyes. His default outfit comprises a long-sleeved black collared shirt, white pants, black elbow gloves, purple socks, and black shoes, with a multicolored long skirt fastened by a white belt and is seen holding a briefcase. He also has optional tentacles and tentacle hair.
Worth noting is that he had an entirely different guise during his time in ANYCOLOR's Virtual Talent Academy (ex. post #8757724), sporting short grey hair instead of long purple hair.
