Hyper Sweat Academy

Hyper Sweat Academy is an adult ecchi comedy visual novel featuring strategic card-based duels at an all-girls sports academy. A mysterious card game crashes onto the campus, possessing the students and making them obsessed; your goal is to break the spell through competition. The core gameplay revolves around one-on-one card duels using simple mechanics—select cards representing different body parts and match pairs or triples to build stronger hands. Winning rounds causes your opponent to lose clothing and earn points, but the same mechanics work against you. Between duels, you attend classroom events, encounter girls around campus, and participate in surprise nighttime meetings. Progress unlocks animated CG galleries, combo videos, and character collectibles on an in-game phone. The game contains approximately one hour of story content across eight classroom scenes, three night encounters, and a weekend event.
