The Mad Dog is Returning to Mushoku Tensei

A Look at the New Trailer for Season 3 of Mushoku Tensei

Mushoku Tensei is coming back for its third season this July, and that means we’re getting into one of, if not the most important arcs, in the entire story. No spoilers from me, though! That would ruin the fun! However, our latest look at what comes next has confirmed that we are getting one arc that some people were worried we’d miss. And it has to do with the most divisive and controversial girl in the series: Eris Greyrat.

I could go on another tangent about how Eris messed up big time by sleeping with Rudy and then leaving him to go on her training arc, but I think I made my opinion on the matter clear. She screwed up, and when she reunites with Rudy, she is going to have to spend a long time making amends for breaking his heart and leaving him depressed for three years. Instead, let’s just focus on what this trailer revealed: we’re going to see Eris’ training arc.

In the anime, the last time we actually saw Eris, she and Ghislaine had left to train and get stronger. Eris had realized that she was too dependent on Rudeus for her own good, and that she wanted to be strong enough to protect him like he had been doing the same for her. With that goal in mind, and wanting to beat the snot out of Orsted, the two women head to the best place for a swordsman to train: the Sword Sanctum, home of the Sword God Style of swordsmanship. And, save for that quick cameo at the end of season two, that was the last time we saw Eris…in the anime.

What did Eris do on her Training Arc

Since the anime focuses on the story of Rudeus, it never really shows us what has happened to Eris while Rudy has been living his life. In the light novels and manga adaptation, though, readers periodically get glimpses into what Eris’ life of training at the Sword Santcum is like. She even gets a brief spin-off manga chronicling part of her time there and the adventures she went on. As is the case with a lot of Mushoku Tensei, though, there are going to be gaps during which we know nothing about the lives of the characters, but that’s not a bad thing. And while we don’t know how much of her time at the Sanctum that the anime will cover, the trailer shows that it’s including the most important parts. That includes the people that she meets, several of whom become important or recurring characters in the story from this point forward. In fact, we’ve already seen one of them back in season two.

Remember that time Linia and Pursena holed up in their room during the mating season of the Beast People and made Rudy fight off all their suitors? And then Badigadi showed up looking for a fight with Rudy? Right before Rudy got his first challenge, we saw a young, blue-haired woman looking at him. That same woman appears in this trailer for the Sword Sanctum arc as someone who knows Eris.

This is Nina Farion, another student training at the Sword Sanctum, and she and Eris come to have an interesting history. I can’t spoil too much about what happens, but let’s just say that Eris’s showing up has a major impact on Nina’s life, for both better and for worse.

While I can’t speak about how the rest of the fandom views Eris, I think a good chunk of us were probably hoping that the anime would cover her time at the Sword Sanctum. Given how she left Rudy to train there, it’s too important part of the story to simply gloss over! As for whether this will be a special episode like what we got for Sylphie or take place over multiple episodes, that is left up in the air. Regardless, I’m looking forward to seeing this gets adapted by the anime. And I’m looking forward to the return of Mushoku Tensei.

Mushoku Tensei Season 3 First Look!

Mushoku Tensei Season 3 Coming in 2026

Well, it would seem that my predictions for the next season of Mushoku Tensei were right on the money. Season three of one of the OG members of the Seven Summits will be coming in 2026, and we have the trailer to prove it, compliments of Anime Expo.

Full disclosure: I was on vacation as Anime Expo was taking place, so keeping up with it wasn’t a high priority. However, even I paid attention when I saw the trailer for Mushoku Tensei: Jobless Reincarnation’s third season came out. And this season could be what ultimately makes or break the anime, as its entering one of the most important phases of the story. And thats not just because of the return of a certain red-head.

What’s to Come in 2026

As was the case with every Turning Point, Rudeus’ life has been drastically altered in a short amount of time. On the one hand, his quest to save his mother ended with his losing an arm, his father Paul, and his mother Zenith’s stuck in a catatonic state. On the other hand, he reunited with Roxy, she joined the Greyrat family as his second wife, and now he’s a father himself. And he intends to keep living his second life to the fullest.

The majority of the trailer is meant to show off the various things that will end up taking place in Rudy’s life going forward. There’s a mixture of faces and locations both familiar and new that come and go throughout the trailer. Besides them, though, the things that fans really need to focus on are the book that we see Rudeus writing in, as well as the images that fly on the screen about fifty-nine seconds in. They only appear for a second, but if you slow down and take a look at them, you’ll notice how dark they seem to be as a group. And you would be right. I can’t say anything about what they’re about, but they’re connected to the book that Rudy’s writing in, and…lets just say that many people are going to end up crying when the anime gets to them. In fact, the anime may dedicate an entire episode to these moments just to show how bad things could get for Rudy.

One of two things that I can discuss at length, though, is the return of Rudeus’ ex, Eris Greyrat. AKA the heartbreaker.

Eris is Gonna Have to do a Lot to Make Up for What She Did

Outside of a quick shot of her in the montage for the end of season two, we haven’t seen Eris Greyrat since she ran out on Rudy. Even if you haven’t read the light novels, though, we all knew she was going to come back. Her going on her anime-training arc to get stronger to protect Rudy was the whole point of why she left. However, if you’ve read my reviews, then you’ll know that I have issues with how she went about things. As bad as Rudy can be sometimes, he didn’t deserve to be emotionally manipulated, stricken with ED, and then left in a state of depression for three years. Needless to say, when Eris does come back, she’s going to have A LOT to answer for, and have to do A LOT to make up for what she did.

The second thing we can discuss, though, is how this season will mark the return of the series equivalent of Sephiroth, Orsted. The trailer has images of him engaged in battle, most likely against Rudy or someone else. Given how their last encounter ended with him barely getting a scratch and Rudy and Eris with PTSD, his return is a big deal.

The bottom line is that when I say that this next season of Mushoku Tensei will be covering the most important arc in the series, I mean it. Novel readers have waited for this for years, and its going to change a lot of what we think we know about the series. And you can bet I’m going to be covering it!
