Nippon Ichi Software

Nippon Ichi Software, Inc. (株式会社日本一ソフトウェア Nippon Ichi Sofutowea, known as Prism Kikaku Ltd. from July 1993 to July 1995) is a Japanese video game developer and publisher. They are responsible for such titles as the Disgaea and Marl Kingdom tactical role-playing series, as well as Phantom Brave and La Pucelle: Tactics. More recently, particularly through their North American branch, NIS America, they have also published anime titles. Its corporate mascot is the Disgaea demon Prinny.

A North American branch of the company, NIS America was founded in 2003 in order to focus on publishing and localizing games for North America. Until 2007, Nippon Ichi Software did not have a branch for PAL regions, resulting in the company partnering with multiple third-party publishers, such as Ghostlight, Koei, Square Enix, and Ubisoft.
