Sotsugyō M: Seito Kaichō no Kareinaru Inbō

Sotsugyō M is an "otome game"; a romantic adventure game aimed at a female audience. It is based on the manga of the same title by Kei Arisugawa and Kyoko Nishiomi, which is itself a spinoff of the Graduation series set in a private all-boys high school. The player is cast as the younger sister of student council secretary Ryūnosuke Sugita; her brother has mysteriously disappeared, and after receiving a strange phone call, she goes to Seiryū High School to investigate, and meets an unlikely group of boys who help her out. Unlike other Sotsugyō games there is no simulation element; this is strictly a romantic visual novel. Throughout the story, the player's choices will affect each boy's affection level with the main character. In the final chapter the player can choose which of the five boys to confess their love to, with the ending determined by the level of affection.
