For a single day Hodai Kudoki has an unrivaled sex appeal and allure, making him irresistible to women and girls around him thanks to an arrow shot by the angel Ekoro. But, there is a catch: once the effects of the arrow wear off Hodai will never be able to have a girlfriend again, provided he doesnt find his fated match and her confession of love before the days end!
Double Peace takes place a year after the events of the previous title with a whole new batch of heroines, students, and teachers, bringing the total number of women in the game to over 70.
In an attempt to lead Hodai astray, as well as tempt him away from his chosen girl, many of the other girls will be quite aggressive with their expressions of love and affection. Some girls might just try for a hug or a kiss, while others will bombard you with their love letters or pushing and hitting you. Girls who are possessed by demons will be especially aggressive!
Players can use the "X-Ray Zoom" feature to see through obstacles, potentially revealing information about various girls and even more. Players can also charge up their shots by holding down the shoot button, landing such a shot will cause the girl it hits to falter making her easier to take out.
Heartthrob Mode is the part of the game where players can view up to three girls from multiple angles, as well as make use of the touch panel. In order to enter Heartthrob Mode players must first max out their Heart Gauge.
