Hell Teacher: Jigoku Sensei Nube (Season 1, 2025) – A Supernatural Reboot That Redefines Nostalgia with Guts and Heart

“Heavens and earth, give me the power to defeat this demon and bring forth the light of dawn!” These words, spoken by the indomitable Meisuke Nueno (aka Nube), echo through the halls of Dōmori Elementary in Hell Teacher: Jigoku Sensei Nube’s 2025 anime reboot, a revival that doesn’t just revisit a ‘90s classic but reimagines it with a boldness that demands attention. Studio Kai’s adaptation of Shō Makura and Takeshi Okano’s beloved manga (originally serialized in Weekly Shōnen Jump from 1993–1999) is a masterclass in balancing retro charm with modern sensibilities, delivering a Season 1 that’s equal parts spine-chilling, heartfelt, and unexpectedly introspective. This review dives deep into why Hell Teacher Season 1 stands as a next-level triumph, blending occult action, emotional depth, and a daring narrative overhaul that sets it apart from any other reboot in recent memory.

A Reboot That Takes Risks and Wins

When Hell Teacher: Jigoku Sensei Nube premiered on July 2, 2025, with a one-hour special featuring episodes titled The 99-Legged Bug and Rampage of the Fox, fans of the original 1996 anime and manga braced for a nostalgia trip. What they got instead was a bold reimagining that respects its roots while carving a new path. Unlike other recent remakes (Ranma 1/2, Rurouni Kenshin), which often stick closely to their source material, Studio Kai takes a daring approach by restructuring the narrative. The first two episodes alone condense and resequence manga chapters, introducing key characters like Hiroshi Tateno and the fox spirit Tamamo earlier than expected, while reworking their arcs for maximum impact.

This isn’t a lazy retread. The reboot’s narrative changes—such as making Hiroshi a temperamental new student rather than an established one—add fresh stakes and emotional weight. By accelerating certain plotlines (e.g., Ms. Ritsuko’s skepticism of Nube’s paranormal antics), the show establishes its core themes—duty, protection, and the clash between the mundane and supernatural—within the first hour. These choices could have alienated purists, but they succeed because they preserve the spirit of the original while making it accessible to newcomers. The result is a reboot that feels both familiar and thrillingly unpredictable, a rare feat in an era of safe adaptations.

Nube: The Heart of the Show

At the center of Hell Teacher is Meisuke Nueno, voiced with infectious charisma by Ryōtarō Okiayu (Demon Slayer, The Prince of Tennis). Nube is a paradox: a clumsy, easygoing teacher who’s also Japan’s only psychic educator, wielding a demon-possessed left hand to exorcise supernatural threats. Okiayu’s performance captures Nube’s duality—his goofy charm when bantering with students and his steely resolve when facing horrors like the 99-Legged Bug or a vengeful anatomy doll spirit. His catchphrase, “Keep your hands off my students!” isn’t just a battle cry; it’s a vow that underscores his role as a protector, making him one of anime’s most compelling teacher protagonists since Great Teacher Onizuka.

Nube’s Demon’s Hand technique is more than a cool gimmick. It’s a narrative device that symbolizes his burden: the power to save comes at the cost of carrying darkness within. The show doesn’t shy away from exploring this tension, particularly in episodes where Nube hesitates to unleash his full strength, fearing collateral damage. This introspection elevates him beyond the typical shonen hero, grounding the supernatural spectacle in human stakes.

A Haunting Blend of Horror and Humor

Hell Teacher’s greatest strength is its genre-blending alchemy. The show is a love letter to Japanese folklore, urban legends, and occult horror, with each episode introducing a new supernatural threat—be it a multi-legged insect demon, a fox spirit, or a sentient anatomy doll wielding broken glass. These creatures are genuinely unsettling, with Studio Kai’s retro-inspired designs (huge eyes, spiky hair) juxtaposed against macabre visuals that evoke ‘70s and ‘80s anime like Gegege no Kitarō. Episode 3, in particular, delivers a twist ending so creepy it’s tailor-made to haunt Japanese schoolkids, though its impact resonates universally.

Yet, the show never feels oppressively dark. It balances gore and scares with slapstick humor and heartfelt moments. Nube’s bumbling attempts to woo Ms. Ritsuko or his students’ mischievous antics (like mocking his paranormal obsession) provide levity without undermining the tension. This tonal tightrope walk is a testament to director Yasuyuki Ōishi and series composer Yoshiki Ōkusa, who ensure the show feels cohesive despite its episodic structure. The kids in Class 5-3, especially Hiroshi (voiced by Ryōko Shiraishi), act like real children—spunky, flawed, and vulnerable—making their brushes with danger all the more affecting.

Studio Kai’s Visual and Sonic Triumph

Studio Kai, known for smaller projects like 7Seeds, steps up in a big way with Hell Teacher. The animation, while occasionally simplistic in action scenes (low frame rates and recycled frames), compensates with vibrant character designs and a retro aesthetic that feels like a love letter to pre-digital anime. The bold colors and exaggerated expressions capture the manga’s essence, while atmospheric touches—like shadowy corridors or eerie yokai designs—enhance the horror. The opening sequence, storyboarded by Ai Yoshimura, is a visual feast, blending occult imagery with dynamic character shots, set to a haunting score by Evan Call (Violet Evergarden).

The voice cast is a standout. Okiayu’s Nube is the emotional anchor, but Shiraishi’s Hiroshi brings a raw intensity to the troubled student, making his growth from hothead to hero-in-the-making compelling. The ensemble, including Misano Sakai and Misuzu Yamada, breathes life into the diverse cast, ensuring even minor characters feel distinct.

Why It Stands Out

What makes Hell Teacher Season 1 truly next-level is its willingness to evolve the source material while staying true to its core. The manga, with over 29 million copies in circulation, is a cultural touchstone in Japan, and the reboot honors that legacy by addressing modern anxieties—trauma, belonging, and the pressure to protect—through a supernatural lens. Unlike DAN DA DAN, which leans heavily into chaotic humor, Hell Teacher grounds its occult action in emotional stakes, making every victory feel earned and every loss poignant.

The show also subverts expectations by humanizing its monsters. The anatomy doll spirit, for instance, isn’t evil but a product of neglect, embodying the idea that loved objects develop souls—a concept rooted in Japanese animism but universally resonant. This nuance, combined with the show’s episodic yet interconnected storytelling, makes it a standout in the crowded 2025 anime landscape.

Room for Improvement

No show is perfect. The animation’s occasional budget constraints are noticeable in high-action scenes, where static frames or recycled sequences can disrupt the flow. Some fans may also bristle at the narrative changes, like Tamamo’s early introduction or the compressed Ritsuko arc, which skip beloved manga moments. Additionally, while the kids’ trauma is acknowledged, the show could delve deeper into their psychological aftermath, especially for Hiroshi, who witnesses horrors no child should.

A Must-Watch for Old and New Fans

Hell Teacher: Jigoku Sensei Nube Season 1 (2025) is a triumph of reinvention. It captures the spooky, heartfelt essence of the original while forging a fresh identity that speaks to today’s audience. Whether you’re a ‘90s kid revisiting a childhood favorite or a newcomer drawn to occult action, this reboot delivers chills, laughs, and a protagonist worth rooting for. Streaming on YouTube and airing on TV Asahi’s IM Animation W block, it’s a perfect blend of nostalgia and innovation.

Final Verdict: 8.5/10 – Hell Teacher Season 1 is a bold, refreshing reboot that honors its roots while pushing boundaries. It’s a love letter to horror fans, shonen enthusiasts, and anyone who believes a teacher’s greatest power is protecting their students—no matter the cost.

“Keep your hands off my students!” Nube’s back, and he’s never been better.
