Though very reluctant, the angel Rain has been chosen as one of the four candidates in for consideration to become the next god. He and the four other candidates will decend to earth for one year so that they may perform a test to determine their suitability for the position, with the ability to reveal their true identity to one human being of earth.

From Tokyopop: Shima and Kaori are two teenage detectives who have their own odd-jobs agency, Anything Inc. If they take your case, you know your satisfaction will be guaranteed! Shima is a smart kid with a knack for solving other people’s problems. He’s recently lost his parents to an arson’s fire. Now the sight of fire makes him cringe, often reducing the super sleuth into a pool of tears. Kaori, a supermodel, seems an unlikely partner for Shima, but they’ve been best friends since Kaori hired the junior Sherlock to rid him of a troublesome stalker. For some reason, Shima is comfortable mourning in front of the handsome Kaori; on his end, Kaori trusts Shima to help him suppress his over-aggressive modeling persona, Kyo.
