You state you chose the name because it sounds cool and not because of its meaning, what is the word's meaning? - JayLR 09:19, 9 October 2007 (UTC)

I'm not completely sure, but the word "waru" means evil and "jin" means inhabitant. So, I think it means "The evil inhabitants of Siheika", but I've never mentioned a place named "Siheika". So , it's really a very senseless name. - SSJKamui 12:44, 9 October 2007 (CEST)
