Well it is true that each character, in some way or another, portrays a part of its creators' personality. That's definite.
Sho is a new character for me though as i usually play the loner/hides feelings type of guy. I'm experimenting with a character a little more carefree, openhearted and easy to read. It's going good so far, considering i dont have much experience with this kind of personality ^_^
