Isaku

In *Isaku*, you step into the shoes of Kenta, a high school student trapped with his classmates and teacher on the top floor of an abandoned school by the eldest Itou brother, Isaku. Your goal is to escape the locked building. The only exit is a stairwell, but each floor's door is sealed. Search rooms for keys and clues to unlock each level, descending toward a final confrontation with Isaku. This interactive adventure blends escape-game mechanics with map movement and features completely avoidable netorare and rape content, focusing on survival and tension.
