PLOT:
Shouta Yamakawa is no good at getting girls, so he mostly sticks to 2D girls. His favorite is Sora Nagihara, the perpetually sweet, sickly, kitty-eared heroine of of his favorite manga Tama X Kiss. Imagine his surprise when one day, Tama pops right out of the latest issue acting nothing like the demure heroine of his dreams. Brash and perverted, Sora is convinced that Shouta should be king of the world. Thus she sets out to turn the girls of the school into Shouta's harem by any means necessary.
