Pita Ten

Plot
Kotaro, who has lost his mother, was pretty much supposed to be your average boy, worried about the pressures of education while enjoying a simple life with his friends. Much to his despair, he one day finds the overly cheerful Misha at his door, asking to be friends out of nowhere. Even more shocking is that Misha is an apprentice angel, yet she does more bad then good. Along with Kotaro's school friends Takashi and Koboshi and the so called devil Shia (once again a demon apprentice being able to do more good then bad), the group of friends spend their days getting into all sorts of adventures and troubles.

Kotarou continues his daily life until Shia absorbs his life energy and leaves town. Kotarou investigates and discovers Shia is his great-grandmother who is searching for his dying great-grandfather, Taro Higuchi. After the revelation, Shia mourns Taro's death before she also dies. Afterwards, Kotarou learns that Misha's angel exam is to help Kotarou find happiness; regardless of the result, the two will separate when the exam ends. Realizing Heaven's true intent, Kotarou asks Misha to rid him of his ability to see angels as he has to search for happiness himself. His actions allow Misha to become an angel and the two live their separate lives.
