Rin is a private investigator with an advantage: near immortality. Thanks to the spores of the Yggdrasill tree, both she and her assistant Mimi have lived many years longer than the average person. That isn’t to say that being immortal doesn't have its problems. With 'angels' wanting to devour them, the being Apos sending wave after wave of professional assassins to kill them, and constant hangovers from long nights of drinking, being immortal still has its downsides. With Apos' attempts at removing them from the picture increasing, can Rin and Mimi figure out what he is after so they can return to their morning shots of Vodka?
