Hatoful Boyfriend: A School of Hope and White Wings (はーとふる彼氏〜希望の学園と白い翼〜 Hātofuru Kareshi: Kibō no Gakuen to Shiroi Tsubasa?), usually shortened to Hatoful Boyfriend (はーとふる彼氏 Hātofuru Kareshi?), is a Japanese dōjin soft otome visual novel released in 2011 for Microsoft Windows and OS X. It was developed by mangaka Moa Hato's dōjin circle PigeoNation Inc., and is the successor of a Flash game of the same name she created for April Fools' Day in 2011. A free demo version of Hatoful made with the FamousWriter engine was released later that year, followed by a full commercial version released on October 30, 2011 at COMITIA 98, and an English version released through digital distribution in February 2012. An international remake by developer Mediatonic and publisher Devolver Digital was released on September 4, 2014 for Windows, OS X, and Linux. The game will be ported to PlayStation 4 and PlayStation Vita in Q2 2015.

Hatoful Boyfriend is an interactive text-based visual novel that follows a branching plot line, with the player's decisions determining which of the game's multiple endings they receive. The title is a pun on the wasei-eigo word hātofuru (ハートフル?, "heartful", also "hurtful"), and the Japanese word hato (鳩?, "pigeon", "dove"), as the game features pigeons and other birds as major characters. The game is set in a version of Earth populated by sapient birds, and its main story follows the player character and protagonist—the only human attending St. PigeoNation's Institute, an elite school for birds—as she finds love among her avian acquaintances. less
