Since there was no choice,you decided to ask someone there for help and when you entered the courtyard,it turned out to be a place for practicing swordsmanship.

but suddenly there is a woman with gray hair and glasses talking to you while holding a stick.

Niwa: seductive smile Well,do you want to practice swordsmanship with me,boy?
