Mushoku Tensei: Isekai Ittara Honki Dasu - Eris no Goblin Toubatsu

I usually don’t review OVAs, but I’m still bitter about the failure of my actual Mushoku Tensei review, so here I am.

This episode is pretty great. It's an Eris side-story with awesome action, new characters, extra world-building, & even a satisfying little mini-arc where Eris finally gets to take the lead & do something herself. Mushoku Tensei is the only isekai that actually makes me feel like I’m watching another world, & getting to see more of its beautifully realized setting will always be a delight.

If it didn't go without saying, anyone who enjoyed the series will also enjoy this OVA.

Thank you for reading.

Just a disclaimer. I am absolutely obsessed with the MT series and this review is very obviously biased. But then, what review isn't?

Alright so I just watched this and I don't think I have ever squealed with delight as much as I have watching this OVA. Heavy spoilers ahead, needless to say.

Story 8/10

The story was simple nothing to complex. Its just one of Eris' side adventures that wasn't animated along with the main storyline since it would've affected the mood. Simple doesn't mean "not good" and I thoroughly enjoyed it. It introduces a couple of new characters that will be very important down the line ... and for me they were all done absolutely right.

Art 10/10

The art was outstanding as usual. The perfection that we have come to expect from Studio Bind. Nothing like Demon Slayer Season 2 but an art style that perfectly fits the MT universe. Besides the action scenes were just an absolute feast for the eyes.


Sound 10/10

Both the OP and ED are the same ones from Part 2. Regardless I got chills from the OP regardless and the soundtrack was also the same. I dont really have a lot to say apart from the fact that I enjoyed it.

Character 10/10 not even a question

The characters are what make Mushoku Tensei and that stays true for this 20 minute episode. The sheer delight on Eris' face as she explored the city, Cliff's arrogance that was perfectly captured and Ruijerd following Eris juuuust to make sure. Everything was perfect.

Enjoyment 10/10

If its not quite obvious yet I am insanely obsessed with Mushoku Tensei. For me it is just the perfect blend of characters, visuals, story and fantasy. As someone who has read the LNs I obviously see it with rose coloured glasses but knowing that doesn't dampen my enjoyment in the slightest. The VAs are objectively amazing as is the art and sound.

If you liked the main series DO NOT skip this OVA because who wouldn't like more Mushoku Tensei. Or fans of the series at least.

Mushoku Tensei's special episode, "Eris the Goblin Slayer" continues the series' strong trend in delivery with its content from the writing to the animation as usual.

There's more focus on Eris and what she's up to in Millishion during the events of Episode 16 in her own adventure, and the show does a good job in showing how much she has grown in her journey with Rudeus and Ruijerd from not only a combat standpoint but a maturity standpoint too. Sure she has her bursts that make her feel like the old Eris but she also gives a lot of thought into whatever decision she has ... to make, and tries to do good deeds on her own too to continue with helping out the Superds in the process while just enjoying her own adventure in the process. She's attached to Rudeus but she also wants time to herself to see how far she has progressed and this OVA showed that off well.

Even had a great character introduction in Cliff, and the episode sets up well for future seasons to deliver upon whether it is with Cliff as a character or the politics teased in the episode with what's happening underneath the heavenly looking country.

Action was stellar as usual, the staff just knows how to make action feel quick yet impactful and brutal without wasting any time on meandering dialogue. Again, shows how much Eris has grown as a fighter too given her amount of training with strong people like Ghislaine and Ruijerd over many years.

This was a super fun episode that actually has some plot relevance for a special episode and not just being a fanservice, waste of time kind of episode. Delivers a lot for Eris' character, and some really good build for future seasons to come, especially with Cliff's character. I loved the opening montage that visualized his life in the past with unique direction choices too for this series rather than having a massive exposition dump of Cliff's life beforehand. Lots to love here, the staff and director definitely put a lot of effort into bringing the most out of this one chapter from both an animation and storytelling perspective.

This kind of episode fits being separated from the main anime due to feeling too different from what Rudeus was doing at the time which the anime was focusing on, but was still great on its own. For some people like me, even refreshing given how the series can explore its quality side characters even more in a free way with this kind of episode. I'm just excited for season 2 to come now, this series really does showcase tons of potential to being an all-time classic and this episode is just a part of that journey while still more than delivering enough to be a damn great episode.
