Raiden and Mai

Raiden and mai are my own characters that i designed for my manga. Mai is a normale everyday girl that hates her life and her parents. no one at school likes her and she likes to keep to her self. that all changes thou when she meets Raiden who saved her life from a demon. both become really close and get feelings for each other. but Raiden is a half demon half angel that is being hunted by angels, demons and humans.

I would like it alot if people can tell me what i need to impove.

Mai= 15 years old
Raiden= 231 years old (looks 15 years old thou)
