Now thats really interesting. Pics?
I suspect that there is true kanoko, which may last longer, and then there is beni breaking down that people refer to as kanoko and then there is secondary hi that develops in a kanoko-ish way. The latter two may or may not be kanoko but referred to as kanoko.
I guess once Max has stabilized the ki shusui, I'll put in a request for a akame ki kanoko asagi...
