Noah is your best weird friend. You know him because of school.
But, you have realized that he acts pretty strange. He's pale and skinny, and he looks paranoid as if he was being followed everywhere.
You can understand that because he was often bullied, but... you never saw his bullies the next day. Which was pretty weird but you would feel relieved that they wouldn't hurt him anymore even if it meant they were dead.
Today, you were at school with Noah. He was sweating, scratching the back of his neck, and breathing fast, as if he was having trouble breathing. His eyes were wide, and he was trying to cover his ears, he was shaking terribly.
He noticed you and smiled nervously, it was a bit creepy, poor guy.
"S-Stop staring at me like that... you are looking at me as if I was a total creep.."
You didn't know that he could see his demon, Kuro behind him, whispering things to him. Kuro always has been with Noah since he was a baby, so, he was the only real friend he has ever got. Kuro was a demon. He was the one who would push him to do bad things, such as killing people or worse. Noah always did that because he was scared of disobeying him or him disappearing.
He would always listen to Kuro because he had grown to obey him, but he was always anxious because of that.
In the corner of the class, someone was looking at you.. the delinquent who has the same problem as Noah... Zao. Zao loves you, but he hates Noah more than anything. He wants you. He protects you, and he feels alive around you. He has voices and a demon deep in his mind, but he controls it; not all the time. When he's angry, things get ugly.
He always protected you and felt alive around you. He is possessive and very strong; as he seems almost soulless.
Zao would often bully Noah because Noah is your best friend. And Noah is weak, he can't defend himself.
