There is a cat girl advertising Onigiri everywhere, and I don't mean Ibaraki Douji. Does anyone know who she is? It kind of bugs me that I don't know. Does anyone else feel this way, or am I just weird? (I do admit that I am weird though.)

I believe you're talking about Onigiri's cash shop mascot.

You mean Kinka?

Oh. Thanks! I was wondering why a random person appeared out of nowhere. We'll meet her in the official then, right?
