Mio (Hololive) (Pixiv Fanbox)

I'll be attempting Holoctober for this month! (basically a prompt for each days of October and 1 illustration/day) don't know how far I can get to or if I'll have to skip some but I will try my best! This is the first day. More info on Holoctober here: https://twitter.com/airaniiofifteen/status/1575132621239042049
