My Fiance is a Monster Girl!? (Japanese: Boku no Iinazuke wa Monsterkko!?) is a video game that was released in Japan in 2011 under the 'Princess X' label. The title came from the team at the Poison@Berry group, which is one of the partners of the influential organization JAST USA (known as 'The Granddaddy of Eroge'). Being somewhat analogous to the Monster Musume series, the game features an array of fetishes as its protagonist interacts with various monster girls, including robotic and taur creatures.
