Oh, I could see Solider and Dragoon here, (your relation to Tidus, soldiers are supportive and defensive, although so are Dragoons - fiercely loyal to those that they love) although in the end, I think your blunt attitude is best reserved for the Monk class. Strong mix between Dragoon (reserved, loyal, defensive, quiet at times, etc) but I'm really getting Monk, here. The bluntness & honestly just doesn't fit the other classes, I don't think, and I believe that's one of your stronger qualities. :)
