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...

23rd century Japan... a land overflowing with moe, where little sister vs big sister vs childhood friend are the major questions of society... Or at least it was, until Gin and his sisters somehow changed the future! Now the prime minister is some old guy with glasses and all the signs are written in indecipherable kanji! This is bad! There's got to be some way to change the future back to the way it should be!
The 23rd century is back to normal: The prime minister is a 2D character again and kanji has been banished to the history books... Except for the appearance of the Special Cultural District that keeps up the old writing style and traditions, that is. But that shouldn't affect Gin Imose's life, after all. Until one day, he receives an email from someone who shouldn't even exist... his long-lost blood-related little sister!
Gin's summer is just beginning, and his family and all his little sisters (even old men that just take the form of little sisters) head to the beach for a little fun, which can only mean one thing: Literary Experiences galore! But Gin is still processing what happened that night in Kuroha's room... Something is changing in him and his relationship with Kuroha... And greater forces are beginning to make themselves felt from the shadows.
Gin continues to spend relaxing days with Yuzu and his sisters, though he can feel Kuroha's jealousy gradually accumulating. But one day, Professor Choumabayshi tells him something ominous: "If you don't get together with Kuroha, she'll be erased." Kuroha has become a key factor to changing history, and the forces of evil are aiming for her. For the sake of moe culture and everyone he loves, Gin paves the way to the future!
