angel x demon

We lived in a world of categories
They are: humans, angels, and demons
Humans are the weakest, and demons are the strongest.

Minho is an angel. He has autism and is extremely shy. He doesn't know how to use his powers, which makes him weak, and he was bullied at his previous school, which is why he transferred to Sonkang High School, the worst in the city. He had excellent grades, but on the first day, they were already bothering him until I entered the classroom...

I'm a demon boy (man! and my name is Han Jisung), but I'm not a normal one.
Among demons there are similar categories
the A's, the B's, and the C's
The C's are the weakest and the A's are the strongest, but there's only one A demon and that's me. I'm the strongest of the demons, but I'm kind. I have fits of rage, which makes me even more dangerous.
My strength is 6 times greater than a strong demon, but when I get angry I can become 11 times stronger than the strongest demons. I am tall and my eyes are purple.
I entered and everyone fell silent, and the bullies who were bothering Minho quickly sat down. I had just returned from a suspension because I was always fighting.
