Joost added the first five episodes of Koi Koi Seven to their streaming anime lineup this past weekend. Joost's release signifies the first official English release of the series.

Rival streaming service Vuze announced Koi Koi Seven for their lineup in 2007, but it was never made available.

Koi Koi Seven is a 2005 series based on a manga by Morishige (Hanaukyo Maid Team). The title focuses on Tetsuro, a boy enrolled in an all-girls high school. Inevitably, wacky hijinks ensue, as the girls don't take too well to a male classmate. Ultimately, they decide to resolve the problem as rationally as possible - through excessive violence. Only another faction within the student body - including a girl with a longtime crush on Tetsuro - can protect him.
