Yamada-kun to 7-nin no Majo

Yamada Ryuu is a second year student at Suzaku High. Ryuu is always late for school, naps in class and gets abysmal grades. His life is a dead bore. The beautiful Shiraishi Urara, on the other hand, is Suzaku High's top student. One day, due to an accident, they somehow switch bodies: Ryuu ends up in Urara's body, and Urara in Ryuu's. They discover that by kissing, they are able to switch bodies.
