After the demon realm is destroyed by a hero, The Demon realm's second in command Jahy and her underlings get sent into another world. This new world is void of magic or any royalty/peasantry status so Jahy is forced to succumb to the work culture in order to make ends meet while also finding red crystals to repair the demon realm. As Jahy becomes more accustomed to this new world she finds it isn't as bad as she initially thought and befriends many humans; She also finds many comrades who have become successful or just plain lazy. The great Jahy will never be defeated is a fun and playful comedy reverse-isekai with a lot of promise, will Jahy be able to repair the demon realm or will she prefer the new life as a bar waitress?
Story & Characters: 7/10
The story at first didn't appear interesting but after watching the first few episodes, I was hooked. Although comedy is a large element in the show, there are underlying elements like plot and narrative goal as well as fairly clear world building. Jahy is a playful take on good vs evil and shows us that change in environment and personal influence can have a significant impact on a person's way of life. After many hardships and successes, Jahy grows to find that there is more to this new world and grows fond of its people. However, that isn't all the story; Despite its comedic appeal the great Jahy has an unpredictable storyline with bad people becoming good and good people becoming bad - It doesn't have the level of violence as other demons series but it raises an interesting idea that "yesterday's enemy is today's friend". After Jahy transports she has many fights which usually end in a stalemate where she drops the rivalry and befrienss her enemies. I really enjoyed this approach instead of losing a character to her own character development. Many of the human characters in the great Jahy aren't scared of Jahy but instead help her in hard times or even fight her which may be the biggest influence in her change of demeanor. Overall, the story is more playful and doesn't unnecessarily kill characters for the main character's development.
Art & Sound: 7/10
The art style is good quality the animation as well for that matter. The character designs for Jahy are generally on the moe-side and in adult form it's more explorative. I enjoyed the set designs because they're consistent throughout the entire show as well as a lot of the character designs. The art tends to fall apart in wide shots and series itself implements a lot of wide shots but they and the slideshow animation don't devolve the overall visual experience as much as I thought they would.
Some of the music in this series is used to sound adventurous and fun which is a good approach. Many of Jahy's hardships come from her ability to transform into an adult so in her child form there is a lot more comedic elements at disposal on her and sound is one of the better elements used. The voice acting is suitable and very entertaining especially from the landlady, Jahy and the hero.
Overall & Enjoyment: 7/10
I'm glad I was able to watch this show; There are a lot of flaws with this type of show like its comedy delaying a lot of plot progression especially in the beginning or some events feeling longer than expected. However, overall I really did enjoy the friction build up especially toward the end of the show with the Demon Lord and Justice.
