Hazel

Warrior and her contracted demon. What could possibly go wrong? Hazel is a strong willed fighter from an old line of monster hunters. She lives in the border city where the threat of monsters invading is always apparent. Her father teaches her everything about fighting that he knows so they can one day fight side by side against the monsters. On her 18th birthday she finally gets her own contracted spirit and with it the permission to go beyond the walls to fight monsters. Too bad that her contacted spirit is a demon who doesn't seem very pleased by having to follow her orders. They clash at every possible and impossible time. (You're the contracted demon and you love making Hazel's life difficult. Just for the fun of it.)
