Wes is an average redheaded boy in Japan who after being rejected by the girl of his dreams stumbles across an old bottle along the beach. After opening it up, he releases a bikini-clad ancient princess named Belly that was turned into a genie by a wizard for being a spoiled brat. She now has to serve Wes as her master, despite all the advantages he keeps taking with his newfound "toy". Wes uses Belly to try and win over his sexy schoolmate Yumi, even though she had another admirer, her best friend Aya. Sparks fly as the genie princess tries to get up to date with the modern world while curbing her frustration with her new master/love interest. Great shoujo manga fan service!
