Hell Teacher: Jigoku Sensei Nube

IS THIS WORTH WATCHING? Here are my points to consider If you have read the OG source and expecting some heavy fan service in this anime, then you would be disappointed If you have watched the 1990's anime version and also expecting some fan service in this anime, then you would be disappointed yet again There’s a gap in my review timeline because I took some time to read the original source material and watched some episode of the 90's anime. After doing so, I must say that I think the anime stands well on its own without the fan service. If it's included, then it would be highly controversial The studio did an excellent job of preserving the nostalgic ’90s feel of the anime while seamlessly blending it with modern animation techniques The animation mostly doesn't looked like it has been half-assed The anime does contain some gory elements, but the studio did a good job of toning them down It may not be as good as Spooky Kitaro, but it serves as a solid alternative for fans looking for a similar experience.

The episode opens as though the previous events have been reset, or at least temporarily put on hold. Nube eventually learns one of Remugyo's weaknesses, providing a glimmer of hope against the seemingly overwhelming threat. The episode also leans on a familiar trope, which isn't too surprising considering the series is an older one. While it may feel predictable by today's standards, I think it fits the storytelling style of its time 🤔

A familiar villain from the previous episode returns, and the episode title makes their identity fairly easy to predict. On top of that, a new and even greater threat makes its debut, one that seems far more dangerous than the returning villain. The suspense keeps building the whole time, and just when it feels like things are about to explode, the episode ends with a cliffhanger that leaves you wanting more.

The yokai featured in this episode belongs to the same category as those introduced in episodes 3 and 5. Interestingly, this yokai is part of Japanese folklore used to frighten children into being more responsible with their possessions. If you have watched Nuraryon no Mago, you may also recognize the phenomenon associated with this yokai. Going into the episode, I expected a darker tone, but it ended up being far more lighthearted than I had anticipated.

This episode takes on a much lighter tone, yet it still delivers a strong emotional punch. The featured yokai this time is, in my opinion one of the more recognizable and less threatening figures in Japanese folklore. Interestingly, its origin closely follows the traditional folktales associated with it, which is a creative touch. This episode is a breath of fresh air after the darker episodes that came before it.

This episode introduces another of Nube's students, and he's just as quirky as the rest of the cast. The supernatural phenomenon featured this time is particularly unusual, blending modern elements with the supernatural. It feels somewhat similar to the one in Ep 6, although I haven't come across anything quite like it before. As for the animation, there is one brief moment that looks a little off but it's so minor that it's easy to miss.

This episode introduces a very popular yokai along with a new character in the series. The story of how she first met Nube is pretty interesting, and her role adds extra spice to the story. The animation in this episode captures the charm of classic anime while incorporating modern techniques that give it a fresh and updated look. P.S. Given that Nube originally featured elements of fan service, the studio opted to preserve Yukime's yokai outfit rather than redesigning it for the adaptation 🤔

This episode is quite different from the previous ones because the " threat " isn't technically a yokai, but an onryo rooted in modern urban legend. The episode is packed with horror and suspense plus the ending is incredibly satisfying. The episode also introduces another function of Nube's left arm, adding an intriguing layer to his abilities.

Great mix of horror + comedy , creepy enough to give chills, funny enough to keep it comfy.

You may find that the yokai this time is pretty much the same category on ep 3, although this one is pretty much rigid and malicious. Katsuya has a good character but did a foolish decision at the start. This is my hunch but something/someone is deliberately sabotaging some stuff, I don't have much of a proof but I can feel it 🤔. The episode isn't graphic considering the nature of the yokai and it was an entertaining yet thrilling watch.

What an odd rendition of the Rokurokubi yokai 🤔. There's an odd animation during Nube's running scene at the start but aside from that the overall animation is quite smooth. Nube should really pick his words carefully, it really has caused misunderstanding 😅. This is quite a dumb yet entertaining episode, especially the unique rendition of the yokai Rokurokubi and Miki's overall character.

I really thought that the episode would be a light hearted one, turned out to be horror. The yokai this time is quite graphic, the studio really made it detailed on the focus shot 😅. The ending felt like an ending of a Spooky Kitaro episode, it felt unsettling and creepy.

Warning before watching: there is some gore scene in this episode, it isn't that heavy but it is still considered gore. It's like a one-two combo punch with this episode, a strong first episode followed by an episode that will not lose to the quality of the first episode. I didn't expect that Hiroshi's condition was premeditated 😯. The studio really flexed their animation in this episode.

To be honest I haven't watched the OG anime, this has completely slipped off my radar considering I have watched City Hunter and OG Gundam way back in my childhood. The studio did a good job adding some modern elements in this reboot while it also feels like I'm watching an old anime (maybe its the character design 🤔). They also didn't get sloppy with the effects and animation. It's a strong first episode, the story also got me hooked since I'm quite a sucker with stories involving yokai 😅

I was a big fan of nube and watched the Og series in 90s.. watching the first episode of this 2025 reboot all i can say that the animation quality is superb, the pacing is kinda fast and it has nice portion of easter eggs to the Og series, very recommended to watch

this episod introduce the meisuke nueno and domori 5th grades students. it shows that Nube brings the supranatural vibes at the start that make the students mocking at them. the old anime soundtrack also played in while nube introduce himself, which is sound nostalgic.

A more mysterious confrontation mixing folklore and morality , Nube must mediate between conflicting spirit forces

Showcases Nube’s iconic demon hand in a showdown, reinforcing his role as protector and martial-spiritual guardian for the kids.

A classic yokai trope where many spirits converge , resulting in big spectacle sequences. Good pacing and high tension.

A lighter, more heartwarming arc involving a girl yokai tied to happiness. Balances the series’s darker beats with softer character work.
