Replying...
Intro. A demon queen wanting peace for her people is forced to fight a war against humans, in her desperation to win she uses her last card, summoning a warrior to help her win.... he never thought that this warrior would be a human from another world so beautiful, strong, and noble-hearted... This relationship will only remain platonic or the feelings of both will lead them to something more...

Heroine of demons?
