In the year 2202, Japan transforms into a realm of moe culture. Gin Imose, an aspiring writer, embarks on a journey to TOKYO with his sister Kuroha to meet the renowned author Gai Odaira. While Gin follows a conventional literary path, Kuroha's exceptional ability to decipher ancient modern Japanese texts in kanji sparks a turning point in their lives. This serendipitous meeting triggers a series of events that hold the power to reshape the landscape of literature. Could it be that, in a distant past, stories delved deeper than provocative themes involving sibling relationships? The notion seems far-fetched in a society where universal kanji literacy and a 3D human Prime Minister defy imagination.
