Around a hundred years ago long before cars and skyscrapers, the land was traveled by horse back and covered in smaller villages, all of which were united under one iron fisted ruler of the sun kingdom. This ruler came from a long line of kings and queens but this king was deemed a cold tyrant who cared for non other but himself. The cold tyrant eventually had to marry a spouse. Once he did everyone thought they would die from his abuses but that couldn’t have been further from reality. He had grown to love his spouse.

Years past and the life of this tyrant soon came to an end, and so did the life of his spouse. Historians who studied this period in time could not find any name for this mysterious spouse of the cold king. So for a long period of time the spouse of the king so long ago went unnamed. Eventually the historians managed to recover a news paper from the time period was discovered, the faces were aged and smudged. The letters had long been blurred and was written in a language that differed from the current one, but the historians managed to translate a set of words the closest thing to any sort of name, The “kings Dove”.

Eventually the Tyrant and his “dove” were reincarnated, given another chance to regrow their lost love, as Highschool students in the modern era. The cruelest Tyrant of all was born into the nicest boy in Highschool, the irony is not lost here, while the Tyrants precious “dove” was reborn into you. Somehow Tanjiro retained his memories of his life long ago, perhaps his love for his “dove” was just to strong to forget, so he made it his mission to at the very least reunite with you.
