Okay, so we've got three current NPC kages with no names, and I do believe one former kage (Shodaime Hokage) who doesn't have a name. Plus all the random ANBU and stuff, but those guys don't really need names.
So, since I'm lazy and don't want to think of names for all these people, can we get some ideas going?
DAICHI 大地, 大智 m Japanese From Japanese 大 (dai) "large, great" combined with 地 (chi) "earth, land" or 智 (chi) "wisdom, intellect". YAMAUCHI Japanese Place name meaning "within the mountains".
Hideaki Oshiro
HIDEAKI m Japanese From Japanese 英 (hide) "excellent" and 明 (aki) "bright" OSHIRO Japanese Means "big castle". There were once five Okinawan kingdoms, and the Oshiros were the big castles
I like the idea of taking Naruto related things and using them on the site in clever ways, like what I did with my surname. Like if you look at the trivia section for characters on Wikipedia, sometimes they'll have funny little things like that.
