Is the word "Kure" something about demons (since the Kure clan members are legit monsters on their own) or it means something else?
In Shona is means far away so I don't think it has any particular meaning. Many anime have names just for the sake of names without large amounts of reasons why
So it was just a created surname that translate into nothing.
I guess the Etymology of the Kure Clan is then wrong.
Why do you say this?
The Kure Clan page has an etymology, I don't think it really is accurate.
What do you think?
