あらすじ
Everyone recognizes my little sister as a "saint." But to me, she might be a "devil." Everyone praises my little sister, who attends church every day and actively does charity work, calling her a "saint." But because of this, our finances are always in trouble. My sister has donated all the money I've saved to the church. Then a handsome man appears, and he says he's an emissary from the kingdom, looking for a saint. Please, please, take my little sister with you. Right now!
