5 Anime to Watch This September for Every Type of Fan
September 2026 is quietly one of the best anime months of the year, and almost nobody is framing it that way. Everyone's talking about JoJo's Bizarre Adventure: Steel Ball Run finally getting a real release schedule, but that's only one piece of it. A Satoshi Kon masterpiece is hitting a major streamer for the first time ever this month, a dark fantasy trilogy is closing out, and a Fullmetal Alchemist creator's new series is deep into its most unsettling arc yet. Whatever kind of anime fan you are — shonen loyalist, horror completionist, or someone who just wants to see how a trilogy sticks the landing — there's a September 2026 anime pick built for you. Here are five, sorted by fan type.
⚡ Quick Answer
The best anime to watch in September 2026: JoJo's Bizarre Adventure: Steel Ball Run for shonen fans (Netflix, Sept 25), Daemons of the Shadow Realm for mystery fans (ongoing weekly), Perfect Blue for horror/classic-cinema fans (new to Netflix Sept 1), Mononoke: The Ashes of Rage for dark fantasy fans (Netflix, Sept 29), and One Piece's Elbaf Arc for loyal binge-watchers (ongoing weekly).

For the Shonen Action Fan: JoJo's Bizarre Adventure — Steel Ball Run
If you've been waiting on Steel Ball Run, September is finally the payoff. After a single-episode release in March 2026 sparked real fan backlash, Netflix corrected course: the show's 2nd and 3rd Stages — 11 episodes covering Johnny Joestar and Gyro Zeppeli's crossing of the 750-mile "Devils' Palm" desert — begin streaming weekly every Friday starting September 25.
📊 Key Stat: This is Part 7 of Hirohiko Araki's manga, and the anime's first season already covers five prior JoJo arcs available on Netflix — Phantom Blood through Stone Ocean — so newcomers have a real on-ramp before Steel Ball Run's cast even shows up.
In my experience, JoJo is the rare shonen where the fandom's patience actually gets rewarded. I sat through the original one-episode drop back in March fully expecting the usual "and then nothing for a year" letdown, and watching Netflix actually walk it back into a proper weekly cadence felt like the platform finally listening to its own most vocal audience.
Who it's for
- Anyone who's already watched Stardust Crusaders or Golden Wind and wants the next escalation
- Fans who like their shonen with a genuinely weird premise (a horse race across 1890s America with superpowers)
- Weekly-watch people who'd rather ration episodes than binge a whole cour at once
For the Mystery Fan: Daemons of the Shadow Realm
From Fullmetal Alchemist creator Hiromu Arakawa, this Bones-animated series follows twins Yuru and Asa, separated in an isolated village until an attack leaves the adults dead and Yuru face-to-face with a woman claiming to be his true twin sister. He's rescued by outsider Ryuu "Dera" Tadera, who has him summon a pair of daemons bound to uncover what actually happened. New episodes have been landing on Sundays through the summer, and September keeps the mystery escalating heading toward its next cour break.

Who it's for
- Fullmetal Alchemist fans looking for a spiritual successor with a fresh cast
- Viewers who want mystery box storytelling that reveals a little every week
- Fans of grounded fantasy that mixes rural folklore with modern-world danger
For the Horror & Classic-Cinema Fan: Perfect Blue
This is the one I've been waiting to recommend for years. Satoshi Kon's 1997 psychological thriller — about a J-pop idol, Mima Kirigoe, who leaves her group for an acting career and is stalked by an obsessive fan as her identity starts fracturing — arrives on Netflix for the first time on September 1. It's a film that predates and arguably out-does most modern "unreliable narrator" thrillers, animated or otherwise.
💡 Pro Tip: Watch this one alone, at night, with subtitles rather than dub — the sound design does a lot of the psychological heavy lifting.
When I first tracked down a VHS copy of Perfect Blue years ago, half the appeal was how hard it was to find. Having it sit on a mainstream streaming service now feels almost strange — but it also means an entire generation of horror fans who've never had legal access to it finally can.
Who it's for
- Psychological horror fans who want something smarter than jump scares
- Anyone curious about the anime that visibly influenced Black Swan and Requiem for a Dream
- Film-history completionists finally getting a legal, easy way to watch it
For the Dark Fantasy Fan: Mononoke — The Ashes of Rage
The third and final film in the Mononoke movie trilogy, directed by Kenji Nakamura, arrives on Netflix September 29. The Medicine Seller still senses an ominous presence inside the inner palace, and this closing chapter has him facing a Snake God that's been strangling maids to death within the Inner Chambers. Mononoke's visual style — flat, painterly, almost stage-play-like framing — remains one of the most distinctive looks in modern anime, and this finale is the trilogy's highest-stakes entry.
| Pick | Where to Watch | September Date |
|---|---|---|
| Steel Ball Run | Netflix | Weekly from Sept 25 |
| Daemons of the Shadow Realm | Netflix / Crunchyroll | Weekly, Sundays |
| Perfect Blue | Netflix | Sept 1 |
| Mononoke: The Ashes of Rage | Netflix | Sept 29 |
| One Piece: Elbaf Arc | Netflix | Ongoing, weekly |
Who it's for
- Fans of visually distinctive, stage-inspired animation styles
- Anyone who's already seen the first two Mononoke films and wants closure
- Folklore and yokai horror fans
For the Loyal Binge-Watcher: One Piece — Elbaf Arc
If you've stuck with One Piece for years, September is the last full month before Part 1 of the Elbaf Arc wraps up in early October and the series shifts to a seasonal release format. That makes this the natural point to catch up before the anime goes on hiatus into 2027 — a rare case where "watch it this month" is genuinely time-sensitive advice rather than marketing copy.
⚠️ Important: One Piece is moving to a seasonal release schedule after this arc wraps in October, so September is your last stretch of weekly episodes for a while.
Who it's for
- Long-time One Piece fans who don't want to fall behind before the hiatus
- Anyone who wants a low-effort weekly watch alongside something newer
The Bottom Line
September 2026 rewards patience more than any month this year — the show everyone's been waiting on finally has a real schedule, a 29-year-old psychological thriller is easier to watch than it's ever been, and two long-running franchises are hitting genuine turning points. Pick the one that matches how you actually like to watch anime, not just the one with the loudest marketing push.
