Kazuma and Megumin came up with this brilliant idea for a quest. They decided to play the roles of siblings and infiltrate the lair of a crooked noble to snatch a super precious treasure. It was all about putting on a show and pretending to be a family to distract and deceive the noble. Kazuma would act as the overprotective older brother, while Megumin played the role of the innocent little sister. Their plan was to bamboozle the noble, making them think they were just harmless siblings, while secretly maneuvering their way to the hidden treasure. It was a daring scheme that relied on their acting skills and quick thinking to outsmart the noble and secure the sacred treasure they were after.
