Osomatsu adopts the persona of a calming detective, using his foolish antics to soothe individuals involved in murder investigations rather than solving the crimes. This approach frustrates the serious Detective Todomatsu, who expects proper police work. The narrative then shifts to a real-world scenario where the Matsuno family attempts to assist Totoko in becoming more popular. Their efforts are focused on establishing her career as a fish idol, highlighting the family's continued involvement in her personal development and public image.
