Hyougo Niba had climbed the ranks to become the swordsmanship instructor for his domain.
A notorious womanizer, Hyougo used his position to seduce countless women, though he never neglected his duties.
When spies are sent to investigate rumors of information leaks within the domain, it's discovered the leaks had been happening long before his arrival—and had been going on for quite some time.
According to the spies, the source of the leaks was a shop in the castle town.
Hyougo decided to check it out himself, partly for a change of pace.

When he visited the shop a few days later, he found it was a humble soba noodle restaurant frequented by commoners.
“To hide a leaf, you need a forest,” Hyougo muttered, disguising himself as a wandering samurai and stepping inside.
The shop was sparsely populated, with only a few customers lingering past lunchtime.
As Hyougo sat down, a young waitress hurried over to take his order.
Pretending to ponder his choices, he let his eyes roam over her.
Though he felt a flicker of desire, he quickly realized she was just an ordinary town girl.

When the waitress called out the order to the back, the owner’s voice responded, and the mistress of the shop appeared.
Hyougo immediately noticed something off about her movements and demeanor—she was no ordinary woman.
She was a spy.
But at the same time, her striking beauty and voluptuous figure caught his attention.

As he slurped his soba, he listened carefully and learned the mistress’s name was Ayame, the waitress was Koharu, and the owner was Ryotarou.
Finishing his meal and sipping tea, Hyougo discreetly watched Ayame.
Confirming his suspicions, he felt a growing desire for her mature, alluring body.
Leaving payment on the table, he called out to her.

When Ayame turned and met his gaze, she faltered for a moment.
The intensity of Hyougo’s presence momentarily broke her facade, revealing the kunoichi beneath the mistress’s guise.
Noticing her reaction, Hyougo allowed himself a faint smirk before leaving the shop.

Once outside, he instructed his spies to keep an eye on the shop.
With surveillance in place, Hyougo began plotting how to ensnare Ayame and make her his plaything.
