One night, Yuto Hatano wishes his dull school life were more like After School Flare Star, a dating sim he has played countless times. He wakes up the next morning inside the game’s world, but not as the protagonist Shun Ogasawara. He has become Kanji Aku, the game’s villain. The setting is a Japanese high school where romantic events and rivalries play out according to the game’s logic. Every heroine starts with zero affection toward him, and any wrong choice leads to instant death and a forced restart. Kanji must use his expert knowledge of the original game to avoid fatal endings, raise the heroines’ affection scores, and survive every route successfully to find a way back to the real world. Each narrative arc focuses on a different heroine, where Kanji navigates her specific events using his foresight. However, once he successfully conquers a route, the heroine retains no memory of the events, becoming merely more friendly toward him, which forces him to begin anew with the next target while carrying the knowledge of his previous attempts.
