Alice on Deadlines

As punishment for slacking on the job, the shinigami Lapan is ordered to go to the Human Realm in the body of a skeleton to retrieve a wandering soul. However, much to Lapan's lecherous delight, a slip-up lands his soul in the body of the young Alice, a buxom student at a local all-girls' school. With the skirt-chasing shinigami (as Alice) leaving a storm of sexual harassment allegations in his wake, whatever is poor, beskeletoned Alice to do?!
