Love 2 Quad  

러브 2 Quad, らぶ2Quad

One day, Aoi-sensei, a popular teacher at Akakura Gakuen, approached Wataru and requested his assistance immediately. She was an agent from Cradle, an international defense organization, tasked with battling against the enemy "4D". To defeat them, Wataru needed to participate in ecchi activities that would grant him energy through love's power. His imouto-like osananajimi Honoka, classmate Ermalit, expressionless Mirai from the future, and chibi Chitose from the past joined forces but were unsure of their next steps. This marked the end of Wataru's peaceful single life.
