No, it's just his hairstyle, like mine :) Back then, when I was growing out my hair, I grew it out in a standard way. Then summer came, and it got really hot with my hair, and I didn't want to cut it, so I came up with the idea of only growing out the hair on the back of my head, and cutting the hair on the top and sides. That's how the hairstyle came about, and then I discovered Guilty Gear :) And my ponytail isn't that long either.
