What’s it about? Jahy is a formidable demon in the Dark Realm, until a pesky magical girl destroys the crystal that supplies all its evil power. Jahy then finds herself transported to a place called Earth, stripped of her magic and trapped in the body of a tiny girl. Jahy is determined to gather enough crystal shards to restore her kingdom… but sidequests like “paying rent” and “needing groceries” keep getting in the way.
Does The Great Jahy have basically the exact same premise as The Devil is a Part-Timer? Yes, but I’m trying not to hold that against it. Honestly, I think the “reverse isekai” is a relatively untapped genre, and with the constant influx of power fantasies where an Ordinary Boy gets to be a hero in a Euro-inspired fantasy world, it’s pretty fun to explore the opposite situation: a Supreme Villain having to learn to be ordinary in modern-day Japan. It’s the kind of fish-out-of-water supernatural comedy that made the good parts of Dragon Maid good, and can be quite charming if its pulled off right.
The Great Jahy doesn’t quite cast a spell on me in this premiere. Perhaps it’s the style of comedy itself: there’s a lot of yelling, to the point where characters reacting to things loudly is the whole joke some of the time. Perhaps it’s the characters: I’m on board to sympathize with Jahy’s plight, but neither she nor the two human characters were that enjoyable to spend time with. Perhaps it’s my brain instinctively putting distance between itself and a show where an immortal woman is turned into a child-sized girl with no pants on.
