무샤미 ～찻집 명물은 갑옷 무사 소녀～

A long time ago, for searching and subjugation of monsters,
the feudal government established "Task force against monsters."
A samurai girl called Uraha and a ninja called Genmai belong to the task force.
They drop by a teahouse for information gathering and rest.
There is a poster girl called Renge at the teahouse, and she is working alone.
However, through the Genmai's carelessness, the fact that Renge is a dragged-up man is revealed.
His real name is Shouma, and he disguised himself as his older sister Renge.
Renge was very popular with patrons of the teahouse.
Since their parents became sick, she became unable to work because of concentrating on nursing.
If Renge is not there to serve, sales at the teahouse would be reduced drastically,
so he committed himself to disguise her.
Now, the guise came to light, reputation of the shop is damaged,
and Shouma despair of the future of the shop.
