The great Jahy will not be defeated! 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.

It's a comedy about the daily life of a loli (not really tho), what do you expect?

This show is surprisingly good, the comedy might not hit everyone, but the wholesomeness and characters surprised me. This anime is dumb, but in a good way, it's a nice escape from other animes.

I'll make this short, this show has semi-low lows and kinda high highs. The first few episodes may be repetitive and kinda boring, and I think they could have done better at expositions, but as the show progressed it got pretty good. The jokes may not be for everyone, but that's not all to the read more

Is my review biased because I’ve read the Jahy-sama wa Kujikenai! manga before watching the anime? Yes. Alright, now with that out of the way let’s continue.

I am not the type of person to get hyped for things. I have only ever felt minor excitement for new or continuing, video games, anime series, book series, manga series, albums, or nature documentaries. However, I felt a moderate amount of hype for Jahy-sama wa Kujikenai! Upon reflecting on why I felt this way, I concluded that it was because this was the first time I have ever read the manga before watching the anime. An unimportant read more

"The longer the journey, the more profound its challenges, the more it changes all who endure it." - Maghra

Season 2 of Hataraku Maou-sama! has finally been greenlit and confirmed, and Jahy-sama wa Kujikenai! is now once the perfect stop-gap show while waiting for the MgRonalds Madao Satan Demon to rescindle his rightful position. But is this show more than enough to warrant watching this weekly and tirelessly for the 5 months while this aired? Let's find out.

The adaptation from mangaka Wakame Konbu's work of the same name, and you can immediately put two and two together why I and so many others compare this to read more
