The Great Jahy Will Not Be Defeated Review: A Long and Sweet Anime That Exists

After combing through the series episode by episode, it is now time to look at The Great Jahy Will Not Be Defeated and figure out if all the time we spent watching the series was worth it. In original Japanese, the series is also known as Jahy-Sama Wa Kujikenai. Let’s get right to the review!

The Great Jahy Will Not Be Defeated Review- The Plot

Jahy-Sama Stars

“Simultaneously combating starvation, the lack of A/C, and the unavoidable weakness of turning child-sized, Jahy—previously the second strongest being in the Dark Realm—is under great stress. If it weren’t for the destruction of the mana crystal which used to power the Dark Realm, Jahy would still be living a life of power and luxury.

And yet, at the moment, brawling with the landlady over rent is a recurring event for Jahy. Just to have a place to stay and food to eat, Jahy must work part-time. However, her immense pride will not allow her to live under such poor conditions for any longer than necessary. Vowing to reinstate the Dark Realm to its former glory, Jahy continues her journey to reassemble the mana crystal.”- Courtesy MAL Rewrite.

Jahy Speech

The plot to Jahy Sama isn’t the draw for the show, to say the least. It is a rather simplistic one, featuring a tale that we’ve seen quite a few times in shows such as this. It is a tale of wanting to restore your original home back to how it was, a variant of the “I want to go back home” kind of plot. It is not a bad story, by any means. However, it is a little derivative of similar stories that came before it.

What sets The Great Jahy Will Not Be Defeated apart from every other show that came before it is the sheer positivity of it. It has a very straight-laced reward system based on karma, as in if you do good things, good gets done onto you and vice versa. It is a refreshing change from the usual suffering protagonists stumbling through life, making poor decisions and getting rewarded for it. Here, everything is clear as day, even if it isn’t explicitly explained to the viewer and left to interpretation.

Druj vs Jingu

While the main plot of almost every episode remains the same, i.e. Jahy looking for mana crystals to restore the dark realm, the show goes about them in different enough ways and with different enough characters that it doesn’t feel too similar most times. Although the 20  episode runtime was too much for a show such as this, and rather than staying true to the manga and adapting most chapters to the show, the showrunners should have picked the best ones and made the show a normal 12 episodes.

Overall, The Great Jahy Will Not Be Defeated has an emotional plot that manages to be great from time to time when it isn’t dealing with the sometimes tiring storylines and plot decisions that it subjects itself with. There is some brilliance here, especially at the start and towards the end when the plot is tighter, and the story isn’t going anywhere random just because it has to be 20 episodes instead of 12.

The Great Jahy Will Not Be Defeated Review- The Characters

Boss Jahy Puppet

Jahy Sama’s true strength lies within its characters, as most of them are well written and executed while having distinct personalities. Many of them follow the various anime stereotypes and tropes that we already know and love while putting a slight, almost always positive twist on it. On top of it all, the interactions with the main character, Jahy, are all top-notch and leave one wanting more.

Jahy is a sprightly hot-blooded menace who has fantastic interactions with everyone, either due to her not knowing how to live in the human world or her ego due to being the number 2 of the dark realm, as she tells us often. Her arc of going from a miserable and off-putting piece of work to a genuinely caring and supportive character is fantastic. Her character gets a lot of breaks due to her looking like a six-year-old half the time, but that works in her favour because she can show what she is without being judged like an adult. The show not lewding her chibi form is also essential, and I’m glad it doesn’t ever do that.

The side characters follow a very interesting quality pattern, which was weirdly related to their order of appearance. All the characters introduced at the start were the best parts of the show, including the Boss, the Landlord, and Druj, all three of which were phenomenal and played huge parts in the show. Their interactions with Jahy were usually fun but often delved into some very dark and emotional places. They helped Jahy the most out of everyone in the show while remaining their fantastic selves,

All the characters that came after them were on a sliding scale of quality, with the last of them being the worst of the bunch. Saurva and Kokoro were lovely additions to the show, each providing a different and much needed dynamic to Jahy- archenemy and best friend, respectively. Jingu, or the magical girl, was fine at times and overbearing at some others. The Dark Lord and her sister were horrible characters and should have never been in the show. They didn’t fit with the rest of the show while taking it in weird directions.

The Great Jahy Will Not Be Defeated Review- Art and Music

The Great Jahy Will Not Be Defeated operates on the “just enough” scale for both of these aspects. Silver Links is a perfectly adequate studio that makes perfectly adequate anime that doesn’t even aspire to be anything else but “okay” in quality, at least visually. While this Jahy Sama review is more about the happenings inside the show than its appearance, a good look always helps, and a good soundtrack is even more so.

The animation and sound quality in The Great Jahy Will Not Be Defeated is fine. You won’t ever remember any of the OSTs after you switch off your screen, and no frames will stick out to you as particularly beautiful. However, nothing ever looks bad or even mediocre. The opening themes are a different story altogether. While the show’s first opening was perfect for the show and an earworm that you couldn’t get out of your head, the second opening was barely even listenable in how bad it was. The worst opening of both the seasons the show ran for, perhaps.

The Good Jahy Sama Opening

The Great Jahy Will Not Be Defeated excelled in the voice acting department, with big names such as Hana Kanazawa and Ai Kayano supported by some extremely talented seiyuus in the likes of Naomi Oozora, making for a great experience. These performances enhance all characters, and it’s no surprise that the worst character in the show turned out to be the one with no voice at all.


The Great Jahy Will Not Be Defeated was a decent show with a good heart and some great things to offer, but it was too long for its own good while making some weird decisions. You won’t regret watching it, and it will make you smile every once in a while.

Arifureta Season 2 Episode 2 Review: The Next Challenge

Arifureta Season 2 Episode 2 was a decent enough way to pass the time, but the show seems to be getting threadbare as time goes on. Something massive needs to happen soon to retain an interest in the goings.

Love Of Kill Episode 2 was a decent outing and an improvement from the first time we saw the show. There are things to improve alongside entire parts that need to be fixed, but it was good for what it was.
