Pita-Ten

Pita-Ten (ぴたテン) is a Japanese manga created by Koge-Donbo which was serialized in MediaWorks' shōnen manga magazine Dengeki Comic Gao! between the October 1999 and August 2003 issues; eight bound volumes were released. The manga has been translated into English by Tokyopop. The manga was adapted into a 26-episode anime produced by Madhouse that aired on TV Tokyo between April and September 2002. The title Pita-Ten is short for "Pittari Tenshi" (ぴったり天使, lit. "clinging angel"). The plot of Pita-Ten centers primarily on the upbeat character Misha and her attempts to become a licensed angel, and Kotaro, her neighbor. It is generally light-humored, but the anime and the manga end with a serious tone. Three light novels, written by Yukari Ochiai, were published by MediaWorks under their Dengeki Bunko imprint between April 2002 and February 2003. The novels were licensed by Seven Seas Entertainment for release in English. The first novel was released in March 2008, the second volume in July 2008, and the third was scheduled for release in November 2008, but was never published due to Seven Seas putting their light novel line on an indefinite hiatus.
