Maga-Tsuki

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 wellendowed 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!
