Overview:

One day, I accidentally time-warped.
I opened my eyes and found myself in Yamataikoku during the Yayoi period.
Presented before me, where I was held captive, was the dazzlingly beautiful Queen Himiko.
Her beauty, so great that it pales in comparison to any modern idol or celebrity, commanded me to perform a special three-day “purification.” But what exactly was this “purification”?
What is the truth behind this mysterious ritual beyond imagination?
