The average teenage emotionless non-human creature thingy. He's where I get my logo username from, so I'll use him in almost every RP I join.
Akuryuu is one of those quiet, shady guys that you normally see sitting alone in the dark. He normally only has conversations with friends (or enemies), and he mostly seems to have no emotion. However, even if he rarely shows it, he has some.
Since I'm into fantasy and anime-ish RPs, he carries (you guessed it) a sword. BUT NOT JUST ANY SWORD!!! He has a demonic katana (Titled Ankoku, which means darkness) which is stronger than every normal weapon and most magically enhanced weapons.
In almost every RP, he'll normally start off as an innocent young boy who either was an orphan or had an abusive parent. If it's an abusive parent, he normally ends up killing them when he discovers his true power. Because of such, he normally lives alone and sleeps outside, either next to a tree, in a cave, or on top of a gravestone.
