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 recently lost his parents in an arsonist’s fire. Now, a mere glimpse of the smallest fire makes him cringe, often reducing the super sleuth to tears.
Kaori, a supermodel, seems an unlikely partner for Shima, but they’ve been best friends ever since Kaori hired the junior Sherlock to rid him of a troublesome stalker. For some reason, Shima is comfortable mourning in front of Kaori; on his end, Kaori trusts Shima to help him suppress his over-aggressive modeling persona, Kyo.
