The closing years of the Heian period: an era belonging to the Genji and the Heike, and a time when the rising samurai class began to flourish.
It was also the golden age of Sato Norikiyo, the great poet who became known as Saigyo.
This story begins with that poet's daughter, Saigyoji Yuyuko.
It opens the story of the paradise called Gensokyo.
Oh, and by the way, Yakumo Yukari really was only 17 that year, Yuyuko was 20, and Yuuka was 18. Really.
This Touhou fanfiction is set in the Heian period, so it will inevitably conflict with the original setting and may also conflict with historical records. Readers who can't accept these elements should avoid it, or read it with a guardian present.
PS: There is a male protagonist, it's a BG romance, there is no harem, and there is yuri. If that's not your thing, don't read.
PSV: Gathering dust.
