Shouran was and orphan with a demon named Kaikon seal up inside of him.(if u even think this is naruto its not) throughout his life he hated his birthday(August 16 hint hint my bd) because of Kaikons hidden memories of Kaikon the dog demon killing Shourans parents. The kid never know a lot about his parents except a few thing 1.) his parents were extremely well known assassins, 2.) through Shouran full family they had an ability called Materialization where from anything he could summon anything to be in his hands (e.g. weapons, clothes anything but food). and 3.) His father was a huge player.
Shouran is a skinny tanned boy with some what the shaggy wax haircut from maplestory, he has dog ears, a long dog tail with the agile-ness of a monkey tail. (i will try to make my character to look like him)
Shu finally can control Kaikon powers, but he is still discovering newer and newer abilities. When Shouran couldnt controll Kaikon the only thing that could calm him down was ectasy
