Gintama: 3-Z Ginpachi Sensei Episode 4 has taken a different approach to storytelling compared to other episodes this spin-off series has released so far. This was the perfect tribute as a Halloween special, as it had the combination of Gintama humour, parody of other famous shows, and surprisingly also included an emotional message.
Time and again, Gintama has proven itself to be a layered show that is more than just comedy. Gintama: 3-Z Ginpachi Sensei Episode 4 is a blend of ghost stories, school hijinks, and the kind of absurdity only Sorachi Hideaki’s world can deliver.
A horror-themed field trip to the school’s seven mysteries

The episode starts with Shinpachi trying to enter the school during odd hours as he had to take an item he had forgotten. But turns out he meets Gintoki and Kagura as they, too, had forgotten something.
While for a second it seems like they had forgotten something important, Gintama: 3-Z Ginpachi Sensei Episode 4 reveals that each of them had forgotten extremely non-essential items: Gintoki forgot his copy of Jump, Kagura left behind her seven packets of sukonbu, and Shinpachi, ever the straight man, just wants to keep them out of trouble.
As they enter the school, the episode goes into a horror mode as they introduce "Seven Mysteries of the School," which is a parody of another anime, and yet again, the creators were not afraid to openly get inspired by the other series and copy-paste the premise as the plot of this episode.
Out of the trio, it was only Kagura who seemed to be braver than Gintoki and Shinpachi. Gintama: 3-Z Ginpachi Sensei Episode 4 captures the energy of early Gintama episodes, where punchlines are fast, unpredictable, and often end with someone screaming.
Almost all of the mysteries they came across were anticlimactic. The wailing ghost of the staff room was revealed to be a teacher suffering from hemorrhoids and secretly applying ointment.
The eerie piano music being played in the dark was, in be, none other than Katsura and Elizabeth playing random notes for no reason. Even Hijikata’s scene, involving mayonnaise, somehow fits perfectly into this comedic haunted-school setup. Every reveal is classic Gintama: Absurd, unexpected, and side-splittingly funny.
The perfect blend of parody and heart

What makes Gintama: 3-Z Ginpachi Sensei Episode 4 different and memorable than the previous instalments is how the last mystery turns out to be an actual ghostly boy. Although it was not revealed till the end, as the trio went up on the rooftop to find the final mystery, they saw a random boy who was about to take his life.
Gintoki, being the responsible one, tried to talk the kid out of killing himself, and the episode has an emotional moment. The humor in Gintama: 3-Z Ginpachi Sensei Episode 4 slowly fades as Gin’s real compassion takes over.
He reassures the boy that life is still worth living, that there will always be “more interesting things” ahead, whether it is manga, movies, or the idiotic classmates waiting in Class 3-Z. It is a signature Gintama moment: absurdity leading into an unexpectedly beautiful reflection on life.
The show closes on a bittersweet twist. During school hours the next day, Gintoki, Shinpachi, and Kagura review the student records and discover that the boy was, in fact, a ghost. It is a chilling yet touching reminder of how Gintama balances laughter with meaning, often sneaking in a life lesson when you least expect it.
Fan reaction: A perfect October episode

Fans online have been loving everything about Gintama: 3-Z Ginpachi Sensei Episode 4. As the episode aired right before Halloween, many praised how it mixed spooky atmosphere with Gintama’s trademark nonsense.
Moreover, the fandom agreed that it’s great to see the focus shift back to the original trio, Gin, Kagura, and Shinpachi, reminding everyone why their chemistry defines the series, and it was nostalgic to watch them embark on an adventure together again.
Final thoughts on Gintama: 3-Z Ginpachi Sensei Episode 4
Episode 4 hooked its audience with an absurd Halloween premise and left them feeling emotional by getting an important life lesson from Gintoki. This one episode is proof that Gintama can be released in any format, like this spin-off series, but there will be no other anime that could parody with purpose quite like Sorachi’s gang. Whether you are a long-time fan or new to the Ginpachi Sensei spinoff, this is Gintama at its best, unpredictable, unapologetic, and oddly inspiring.
