The Business of Death has lots of opportunity for travel. Tsuzuki and Hisoka travel to Okinawa on assignment to help fellow Guardian of Death Chidsuru find out just what is behind the Miyagi Inn's recent troubles. Is the Miyagi Inn really haunted, or is it all a vicious rumor spread by the wicked president of the neighboring resort hotel? Back in the Ministry of Hades, Watari convinces Tsuzuki to help test his new sex change potion. But something's wrong with the formula, and instead of turning into women, they turn into kids! The antidote calls for belladonna flower, but the Count's garden of poisonous plants has two varieties- red and black. Which is the right flower...and what will happen if they choose wrong?
