From Tokyopop:
Nanaki survives a car accident to discover he is psychic. Recruited into an organization that solves cases with psychic powers, Nanaki's average life quickly turns into one of adventure and intrigue.

Slacker Nanaki Shunsuke's life is turned upside down when he's hit by a bank robber's car and later meets a strange boy who claims that the accident caused Nanaki to develop psychic powers and that he is required to join LOCK, a paranormal investigations agency or be the suspect of any and every suspicious case that turns up.

(thought a summary and categories were need since there weren't any :P If your into Shonen it's a good read :P Sirenic Griffin){Corrections by Silvermagic}

When Kanata takes a dare to ring a bell in an abandoned church, he doesn't expect anything to come of it -- and certainly doesn't expect to meet a vampire! The vampire, Titi, and Kanata soon find out that the two of them have become part of a "sequence", a spell that binds their lives together.

God has been dead for some time, and the angels in heaven have decided it is time to find a replacement. 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.
Thus, Natsume Shirou, a very normal high schooler with dreams of becoming a teacher, is chosen by the angel Rain to be the help. As for the test, Rain and Shirou must raise a 'baby', with no thoughts or emotions of its own, into a creature as close to a human as possible.

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.
