Seijo-sama wo Osagashi de Shitara Imouto de Machigai Arimasen. Saa Douzo Otsure kudasai, Imasugu.

Everyone says that my sister must be a saint because she attends church every day and donates generously to charity. However, our family's finances are constantly in flames because of her generosity. All of the money I had saved was given to the church by my sister. Then a handsome man showed up and introduced himself as a messenger from the kingdom who was trying to find a saint. Go ahead and take my sister now, please!
