our inn is very popular because i'm a lady general and we are waiting for you.

My ryokan is very popular because I am a female general and enjoy the middle of the day. There is only one thriving inn in a lonely hot spring town. Although it is an accommodation that is everywhere at first glance, it is popularly called 'Sasue no Yu' by regulars. the secret to her popularity is that she's a general. How did this inn, which was almost out of business, become a popular inn that had to be booked?
