So Korone recently had a bit part in Youkai Watch voicing an unnamed girl.

Korone: I'm not in the series I'm just voicing an unnamed character.

The character turns out to actually be Korone without her dog ears but keeping her bone hairclips. Also the room is very similar to Korone's streaming background, I was expecting a koronesuki to sneak by the window.

I hope they ask her back to do more voice work. Perhaps this character could make little appearances now and then. At the very least she needs to get revenge for her stolen ramen.
