That's what I've been saying though. The five just happened to be using wind decks.

And Hibiki does have a personality. I described him, in brief, that he was analytical and socially awkward. He was modeled after Spock, but obviously has some differences, like not going into heat every once in a while.

The four years thing though was an oversight on my part. I hadn't caught anything that noted it was a shorter school time because as an American, I'm used to high school being 4 years.
