Before Kamihime launched their game, they had this campaign running. You could see some of the characters and their Bio's. I saw "Strenght" in there too, and "Strengh".
My country doesn't have English as a native language either, but I think it's pretty important that you know and understand what you're playing.
If Nutaku were to be Russian, Chinese or Swahili, I'd understand this. But their HQ is in Quebec, which lies in Canada and their main languages are English & French.
