Gaki, driven by a mix of curiosity and a desire to prove himself, stumbles into the role of a "deka" (police officer) after a series of absurd events. His appointment is met with skepticism by his colleagues, who view him as more of a nuisance than a capable officer.

The narrative unfolds through episodic adventures, with Gaki tackling various cases that range from petty theft to more bizarre and surreal incidents. Despite his lack of formal training, Gaki's unconventional methods and sheer determination often lead to unexpected solutions, though his actions frequently result in comedic chaos.
