OPPAI Ero App Academy: Bigger, Better, Electric Boobaloo

OPPAI Ero App Academy is a visual novel set in Toaru Academy, an all-girls school where the protagonist, Shimojo Kazuma, becomes the first male student. After accidentally manifesting a rare erotic ability during a school entrance exam, Kazuma is transferred to this elite academy where a student's bust size correlates with her special power level. The story kicks off when Kazuma acquires a mysterious smartphone from an interdimensional shop, loaded with "super erotic apps" that manipulate reality in increasingly absurd ways. Each app—from teleporting to bathhouses to transforming into swimwear—enables him to pursue romantic and sexual encounters with the academy's female students and characters from a video game that have somehow crossed into his world. Gameplay revolves around using various erotic apps to "conquer" the game's ten main heroines, each with distinct personalities, powers, and sexual scenarios. The narrative weaves together slice-of-life school comedy with explicit sexual content, including harem and incest routes, parent-child scenarios, and large-scale group encounters. Side characters and NPCs also feature dedicated erotic scenes accessible through progression. The game emphasizes variety in scenario design—beach episodes, bathing scenes, transformation fetishes, and multiple-girl encounters—alongside over 110 CG images and animated sequences for main characters.
