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.
