[RIP Gorou, basically. The nails could very well be a boon here, especially if he scratches behind one of them, just sayin'.]

I don't know if I'd call them that fluffy. You won't see too many here in Tokyo, but over in the West, most of the people you see are Yokai, so there's no shortage of people with fluffy ears. Especially in Kyoto, since it's mostly Kitsune.
