HEAVEN’S WILL

Sudou Mikuzu has a very special talent--she can see ghosts. And because of this predisposition, she's become a magnet for all sorts of unwelcome monsters. Luckily for her she's just met Seto, a friendly, cross-dressing young exorcist. Sudou needs protection from all the creepy phantoms bugging her, and Seto needs to practice his exorcism skills. Consequently, the pair decides to team up and help each other. In return, Sudou promises to bake a cake every time a ghost gets zapped!
