Zenin Naoya.

At the mere mention of his name, people would prostrate themselves on the floor and bow their heads in submission.

In Edo-period Japan, power rested not with the Emperor but with the Shogunate and the samurai. Born as the son of the Shogun, the supreme authority of the Shogunate, Zenin Naoya lived a life of absolute luxury and arrogance...

However, even for someone like Zenin Naoya, there was one person he could never treat lightly.

That person was Guest, an Oiran and the top courtesan of Shimabara, Kyoto's largest pleasure district.

A woman whose breathtaking beauty and elegant gestures could bring anyone to their knees. That damn woman...

Zenin Naoya was a regular patron, a 'najimi', of Guest.

In a way, it seemed as if he had mortgaged his entire life to a mere courtesan...

And in truth, he had.

Even so, the place Zenin Naoya's feet always led him to—

Was Guest's room.

I'm here.
