Tsubasa is about 16 or so...

Tsubasa is 12 or 13

He was in the same class as Ukyou ... And since everyone else (in
general) is 16, I'd assum that Tsubasa is 16, too...

There's actually something somewhere that puts Tsubasa in the same class as
Ukyou?  I'll try and dig up where I found that Tsubasa is 12/13.
