Mayoi Neko Overrun!
From Wikipedia, the free encyclopedia.

Mayoi Neko Overrun! (.........!?) is a Japanese light novel series by Tomohiro Matsu, with illustrations by Peko. As of November 25, 2009, seven volumes have been published by Shueisha under their Super Dash Bunko imprint. A manga adaptation by Kentaro Yabuki started serialization in the sh.nen manga magazine Jump Square on January 4, 2010. An anime adaptation will start broadcast on April 6, 2010. [1]

The story revolves around Takumi Tsuzuki, a boy who lives with his older "sister" Otome, although the two have no blood ties between them. Otome manages a run-down confectionary store called Stray Cats. One day, Otome picks up a mysterious beautiful girl off the streets.[2] Also, many of the characters from the series To Love-Ru can usually be seen amongst the characters, suggesting this is in the same city as that series.
