Lucky☆Starらき☆すた

Lucky Star is a Japanese four-panel comic strip manga by Kagami Yoshimizu. The strip has been serialized in Kadokawa Shoten's Comptiq magazine since January 2004. Cameo strips were published in other magazines such as Shōnen Ace and others. Like many four-panel comic strips, it has no ongoing plot, and typically focuses on the daily lives of the characters.

In August 2005, a drama CD based on the series was released, and in December 2005, a Nintendo DS video game entitled Lucky Star Moe Drill, was released. A sequel, also playable on the DS, called Shin Lucky Star Moe Drill was released in May 2007, and a PlayStation 2 visual novel was released in January 2008. An anime adaptation produced by Kyoto Animation was broadcast in 24 episodes on the Chiba TV Japanese television network between April 8, 2007 and September 16, 2007. A light novel was released in September 2007. The anime has been licensed in the USA by Kadokawa Pictures and distributed by Bandai Entertainment; as of March 16, 2009, all six DVDs have been released. An original video animation (OVA) episode was released on September 26, 2008 accompanied by a drama CD. Bandai Entertainment released the OVA in an English-sub only version on August 4, 2009.
