Ryosuke Kaga learned a valuable lesson about dealing with strangers, especially when they happen to be a wet goddess. In a foolish move, he agreed to share his "essence" with Lisara Restole, a smoking hot Shinigami, or Goddess of Death. However, he soon regretted his decision when she drained him of his energy and his ability to enjoy the things that teenage boys commonly think about. In order to regain his former licentiousness, Ryosuke joins Lisara on her quest, knowing that if she leaves, his immorality will return. However, he soon discovers that the journey will not be easy, as the Goddesses of Death are demanding mistresses who may not release him from his probation of reprobation.
