Shinu was born with a curse, demons were sealed inside his soul, it causes him to lose consiciousness and attack whoever he loves most. Because of that Shinu never let any one get close to him, but he has been trying to free himself and is looking for the sacred documents of joukai from the Shinigami. He bears a sword and uses it to fight of the demons that try to stop his quest for the documents... and yea i just thought it up so its not perfect.
