Shintaro Kago's style has been called "fashionable paranoia," although he has stated the term stems from Western media and he doesn't use it himself.

Many of his manga have strongly satirical overtones (heavily influenced by Monty Python),[1] often parodying Japanese and Russian politics.

Separately, he deals extensively with grotesque subjects such as extreme sex, rape, scatology and body modification (to the extent of forniphilia).

He has also written non-guro sci-fi manga, most notably Super-Conductive Brains Parataxis (超伝脳パラタクシス) for Weekly Young Jump.

He frequently breaks the fourth wall, and he likes to play with the page layout in extreme ways, mostly for comedic effect.
