Weird, I thought her name was spelled "Karua", But eh, Whatever.

Mexican coffee.

If we guide ourselves by that logic, the correct spelling we call that drink over here is "Kahlua"

Although I'm honestly surprised no one has done anything with Karua, Or, "Kahlua"?, Yet, Shocking IMO.

The current naming scheme is, their names are written in Kanji so we're using the Japanese romanized pronunciation of them. So, tagging it char:karua (until a proper family name is given).

However, they clearly are meant to sound like "Mocha", "Cocoa", and "Kahlua".

Same family name as Kokoa. No official romanization that I know of, but I figure "Kahlua" is as good as any until proven otherwise.
