"Kakushigoto" centers on Kakushi Gotou, a single father and manga artist who creates risqué comedy manga under the pen name "Goto Kakushi." Determined to shield his young daughter, Hime, from the potentially embarrassing nature of his work, Gotou goes to great lengths to keep his profession a secret. The series alternates between two timelines: one depicting Gotou's daily life as he juggles parenting and his career, and another set a decade later, where Hime, now a teenager, begins to uncover the truth about her father's hidden life.

In the present timeline, Gotou employs various comedic and often elaborate schemes to prevent Hime from discovering his manga career. These include hiding his manuscripts, lying about his workplace, and enlisting the help of his eccentric assistants, Rasuna, Ami, and Aogu, to maintain the facade. Despite his efforts, Gotou's overprotectiveness and paranoia often lead to humorous misunderstandings and heartfelt moments, highlighting his deep love for Hime.

The future timeline reveals Hime's journey to piece together her father's past after his sudden disappearance. Through flashbacks and discoveries, she learns about Gotou's sacrifices, his struggles as a single parent, and the lengths he went to ensure her happiness. This dual narrative structure creates a poignant contrast between Gotou's comedic struggles in the present and the emotional revelations in the future.

The series balances humor and sentimentality, exploring themes of family, identity, and the complexities of parental love. Gotou's character is defined by his dedication to Hime, while Hime's curiosity and growing independence drive the narrative forward. The supporting cast, including Gotou's quirky assistants and Hime's classmates, adds depth and humor to the story, enriching the dynamic between the central father-daughter relationship. "Kakushigoto" ultimately delivers a heartfelt exploration of the bonds that connect families, wrapped in a blend of comedy and emotional resonance.
