Honestly, trying to figure out the blue exorcist episode guide is a total headache for newcomers. You start watching, things are great, and then suddenly the plot takes a sharp left turn into a brick wall of non-canon confusion. It’s one of those rare cases where a studio—A-1 Pictures, in this case—got a little too ahead of the manga and decided to just wing it.
The result? A timeline that looks more like a broken mirror than a straight path.
If you’re diving into the world of Rin Okumura and his blue flames, you can't just hit play and hope for the best. You'll end up seeing characters die who are alive three episodes later, or watching emotional arcs that literally never happened in the original story by Kazue Kato. It’s messy. But once you know where the "filler" trapdoors are, the show is actually a masterpiece of shonen storytelling.
The 2011 Split: Where Everything Went Sideways
The first season of Blue Exorcist (Ao no Exorcist) started in 2011. It was huge. People loved the dynamic between Rin and his straight-laced brother Yukio. However, about halfway through, the anime ran out of source material. Instead of pausing like Bleach or Naruto usually did, the producers chose to create a completely original ending.
Episodes 1 through 15 are mostly safe. They follow the manga’s introduction and the Exorcist Cram School Enrollment arc. But keep your eyes peeled. Once you hit episode 17, you aren't watching Kazue Kato’s story anymore. You’re watching an anime-original "filler" finale that involves a giant floating castle and a version of Satan that doesn't quite match the manga's later lore.
It’s weird.

For years, fans thought that was just how the story ended. Then, in 2017, the show came back with Kyoto Saga. The problem? Kyoto Saga completely ignores the last nine episodes of the first season. If you watch the 2011 ending and then jump straight to the next season, you’ll be incredibly confused. You’ll ask, "Wait, why is everyone still mad at Rin?" or "Didn't that guy die?"
The "True" Watch Order for Season 1
To keep your sanity, you basically have to treat the 2011 season as a "choose your own adventure." If you want the real story that leads into the sequels, you stop at episode 17.
Actually, even episode 16 is a bit of a stretch, but it's okay for flavor. The real divergence is the middle of the trial. In the manga, the trial of Rin Okumura leads into a very specific set of consequences that the anime totally skipped to give viewers a "big" final battle. If you're using a blue exorcist episode guide to stay true to the creator's vision, you watch 1-17 and then jump across a six-year gap to the next series.
Moving Into the Kyoto Impure King Arc
In 2017, Blue Exorcist: Kyoto Saga (Kyoto Fujouou-hen) arrived. This is where the show fixed its mistakes. It picks up exactly where the manga's "Impure King" arc starts.
This season is 12 episodes long. It’s tight. It’s focused. It deals with the aftermath of the world finding out that Rin is the son of Satan. Everyone is terrified of him. His classmates, who were his friends just a few episodes ago (in the canon timeline), now won't even look him in the eye. It’s a grounded, emotional arc that focuses on the Kyoto branch of the Order of the True Cross.
The animation quality also took a noticeable jump here. The flames look better. The pacing feels less like a frantic race and more like a character study. If you skipped the filler at the end of the first season, this transition is seamless. If you didn't, the first three episodes of Kyoto Saga will feel like gaslighting.
The Shimane Illuminati Arc and the 2024 Revival
Fast forward another seven years. Yeah, Blue Exorcist fans are patient. In 2024, we finally got Blue Exorcist: Shimane Illuminati Saga.
This season is crucial. It moves the plot away from the school and into a much darker, global conspiracy. We start learning about the Illuminati (not the real-world conspiracy theory, but the in-universe organization led by Lucifer). It covers volumes 10 through 15 of the manga.

What’s interesting is how the production changed. Studio VOLN took over from A-1 Pictures. Some fans were worried about the shift, but the core energy remained. The blue exorcist episode guide gets a bit simpler here because, thankfully, they stopped trying to invent their own endings. They realized the fans just wanted the manga on screen.
Beyond the Illuminati
Following the Illuminati arc, we transitioned into Blue Exorcist: Beyond the Snow and Blue Exorcist: The Blue Night Resonates. This is where things get heavy. We start getting answers about the "Blue Night," the event where Satan slaughtered a bunch of high-ranking priests years before the story began.
It’s dark stuff.
Don't Forget the Movie and OVAs
There is a Blue Exorcist movie. It came out in 2012.
Is it canon? Not really. Does it matter? Honestly, yes, because the art is gorgeous. It was directed by Atsuhiro Takahashi, and it has a much different "vibe" than the TV show. It’s set during a festival in True Cross Academy. While it doesn't impact the main plot of the Kyoto Saga or Illuminati Saga, it’s a great piece of atmospheric storytelling.
Then there are the OVAs (Original Video Animations).
- Kuro Runs Away From Home: This is a cute side story about Rin’s cat-sith familiar. It’s wholesome. Watch it whenever you need a break from the trauma.
- The Snake and the Poison: This came out with the Kyoto Saga and gives some much-needed backstory on Mamushi and Juzo.
The Absolute Best Way to Watch Blue Exorcist Right Now
If you want the most coherent experience without the fluff, follow this specific path.
Start with Season 1, Episodes 1 through 17.
Stop there. Seriously.
Don't watch the "Satan's Heart" or "Floating Castle" nonsense unless you just want to see some cool explosions that don't mean anything later.
Next, jump straight into Blue Exorcist: Kyoto Saga (12 episodes).
After that, watch Blue Exorcist: Shimane Illuminati Saga.
Then move on to Beyond the Snow and The Blue Night Resonates.
If you do it this way, the character development makes sense. Rin’s struggle to control his flames feels like a steady progression rather than a weirdly oscillating power level. You also get to see the relationship between Rin and Yukio evolve naturally. Yukio, in particular, has one of the most complex "good guy" arcs in modern anime, but the filler episodes in Season 1 kind of ruin his motivations by making him go "evil" way too fast and for the wrong reasons.
Why the Fillers Happened
You might wonder why A-1 Pictures didn't just wait. Back in 2011, the "seasonal" anime model wasn't as dominant as it is now. Shows were often expected to have a "finished" feel if they weren't sure they’d get a second season. They wanted to give the audience a climax.
Unfortunately, Kazue Kato was still writing the story. The anime writers had to guess where she was going, and they guessed wrong. They made Satan a generic villain, whereas in the manga (and later anime seasons), the lore behind the demons and Gehenna is much more nuanced and "grey."
Summary of the Canon Timeline
- Blue Exorcist (Season 1): Episodes 1-17 (Canon).
- Blue Exorcist: Kyoto Saga: Episodes 1-12 (Canon).
- Blue Exorcist: Shimane Illuminati Saga: Episodes 1-12 (Canon).
- Blue Exorcist: Beyond the Snow: (Canon).
- Blue Exorcist: The Blue Night Resonates: (Canon).
Ignore episodes 18-25 of the original run if you are strictly interested in the official story. They are basically an "alternate universe" ending.
To get the most out of your viewing, keep a mental note of the "True Cross Academy" geography. The school is massive, and as the series progresses, the battles move from the small classrooms to the sprawling outskirts of the city. The detail in the background art is one of the show's strongest points, especially in the newer seasons.
If you find yourself confused during the transition from the 2011 series to the Kyoto Saga, just remember: the trial in the forest was the turning point. In the canon version, Rin is put under probation and forced to pass the exorcist exam under heavy surveillance. In the filler version, the world almost ends. Stick to the probation storyline; it leads to much better payoffs in the long run.

Now that you have the layout of the blue exorcist episode guide, the best thing to do is start from the beginning but keep your finger on the "skip" button once you hit the late teens of the first season. The real meat of the story is in the character growth and the mystery of Rin's origin, which is handled much better in the later, canon-compliant seasons.
Go watch the first few episodes and pay attention to Shiro Fujimoto. His influence hangs over the entire series, and almost every major plot point in the latest seasons ties back to his secrets.
Next Steps for Fans
Check out the manga starting at Volume 1 if you want to see the slight differences in tone that the anime missed. Also, keep an eye on official streaming platforms like Crunchyroll or Hulu, as they often categorize the seasons under slightly different names, making it easy to accidentally start the wrong one. Double-check the release years: 2011, 2017, and 2024.
