The comedy/slice-of-life manga called "Kimi to Boku" by Hotta Kiichi has been animated with 12 episodes! The series started airing yesterday (October 3, 2011).

Story:
Shun, Kaname, and the twins Yuuki and Yuuta have been friends since kindergarten. It's a little hard to tell if they actually get along or not - but even as high-school students, they hang out together. Recently, they've had a new addition; a half-Japanese transfer student Chizuru, who has started to liven up the group. This manga is really just about their daily lives, which aren't particularly passionate or exciting. A tranquil and sometimes comedic story of youthful friendship... -MU
