Mimi Yamato
One Time Luck
They attend a school for higher beings (humans that can use magic, demons, etc.) They dislike one another but are forced to be partners in and out of class. She's the popular, queen be type and he's more of a bad boy. They're both stubborn and refuse to work together during their first battle together and lose. In some time they actually start to trust each other more and romance gets build up from there.
