Ah! My Goddess: Volume 4 - We've Got Tonight

Summer break arrives, and the gang head to the beach. Urd decides it's time to capitalize on two of her favorite things - swimsuits and love schemes! Keiichi is given a mission: if he can't kiss Belldandy on the moonlit beach, he won't be able to spend a blissful eternity with her!
