"Yasuke, 15 years old, is about to build up the courage to confess his love to his childhood friend Akari, who's fallen for him, too. There's just one problem: Yasuke's family lives in a Japanese shrine, and when he breaks the shrine's sacred mirror, it triggers a curse, releasing the cute and well-endowed goddess of misfortune, Orihime, into the real world! Now Yasuke can't ever be out of Orihime's sight; if he gets too far away, he dies, and can only be brought back to life with a quick kiss from Orihime!"
