Boku no Imouto wa Kanji ga Yomeru

The year is 2202, and Japan has become the land of moe. Aspiring author Gin Imose and his little sister Kuroha are traveling to Tokyo to meet with the world famous author, Gai Odaira. Kuroha is uninterested in his orthodox literary style, and amazingly is able to read ancient modern Japanese books written in kanji! This fateful encounter sets off a chain of events that could change the course of literary history! Could it be that, long ago, books could be about more than little sisters showing their panties and getting in compromising situations with their non-blood-related older brothers? Impossible! It's hard to even imagine a Japan where everyone could read kanji and the Prime Minister was a 3D human being...
