otomo (cecilia immergreen)

Otomo is the mascot of Cecilia Immergreen of hololive English, a tiny companion robot as cheerful and curious as its owner. It is a small round robot shaped like a ball, with a winding key sticking out of the top of its head just like the one Cecilia wears. It has simple dot eyes and is often perched on Cecilia's shoulder or bouncing around her feet.
