Gal*Gun: Double Peace (ぎゃる☆がん だぶるぴーす Gyaru Gan Daburu Pīsu?) is a rail shooter Bishōjo video game developed by Inti Creates. The game was released on August 6, 2015 in Japan, July 22, 2016 in Europe, and August 2, 2016 in North America. It is the sequel to the 2011 game Gal*Gun.
Ekoro, a student cupid angel in the process of an exam, must strike a student with a love arrow, which will help the student find the love of their life. The target is protagonist Houdai Kudoki, an unpopular male student at the academy. However, Ekoro notices that Kurona, a demon angel who is also doing a practical exam, has the same intended target of Houdai. In an effort to strike the target first, Ekoro accidentally increases the dose of the arrow by thirty-two times the original intended amount. This makes every girl at the school grow madly in love with Houdai, frantically running after him in an effort to claim him as their partner. At the same time, the aforementioned demon angel is striking girls with her staff, which makes the girls love Houdai in a more physical fashion, which includes injuring him in a fashion similar to bondage. However, the increased dose has an unintended side effect; if Houdai does not find his true love by sundown, he will be destined for a life alone, with no one having any affection for him, not even his relatives.
Sisters Shinobu and Maya, two students at the academy and childhood friends of Houdai are also relevant to the plot. Not affected by Houdai's curse due to a hidden profession as demon hunters, the sisters spend the game hunting Kurona, whilst also rekindling a bond with Houdai, whom they have not spoken to in three years.
The game itself features branching paths and multiple endings.
