>>43924397Oshi is Okayu. Comfy gaming streams is why I picked her up, and even started watching livestreaming vtubers at all after being fairly heavily against them for almost a year (mostly being annoyed by Twitch for 9 years and never even giving Youtube streams a chance until then). Stuck with her even after finding myself enjoying a couple other's streams more overall because I felt some odd enjoyment watching her grow, going from wanting to quit after being told she was expected to take part in idol activities, to being one of the few holos that's had a solo live.
Her voice has changed so that answers that. Appearance I am unsure if you mean a drastic change in outfit design to a new model outright (if she leaves or something). If the former, that technically happened with the boyfriend shirt outfit. She was always the sex cat but never quite that explicitly. In both cases I would still stick with her 100% as the model was never the major factor that lured me in, seeing as I prefer flat chests.
