While she was just a lowly underling in the Dark Realm, Druj has risen in the human world to lead a Fortune 500-equivalent company, and even launched a highly-successful line called For J, inspired exclusively by her desire to see Jahy in outfits other than her usual strappy black number.
But Druj is still miserable as long as she’s not by Jahy’s side, and furious when she finds out Kyouko works for her at her pub (even though Jahy neither employs Kyouko nor owns the pub). Druj still manages to divine a convoluted reasoning for Jahy is still the Same Old Jahy…without any input from Jahy needed.
Jahy has been doing well of late in all aspects of her life in the human world, but she can’t get a decent night’s sleep, and blames it on the grungy futon the landlady gave her when she first moved into her apartment. Feeling like she deserves a reward for everything she’s accomplished, he hits up a home goods store and buys the best futon they’ve got.
Ryou-chan comes by and tells Jahy she’s been scammed, but that claim is undone when moments after testing out the futon, both the landlady and Jahy fall right to sleep next to each other. This is the scene that greets the manager, who is happy to see what good friends Ryou-chan and Jahy have become.
Unfortunately, the sisters came to Jahy’s to deliver a spot of bad news: the water of the apartment building has to be shut off for three days. Instead of going without a sink and toilet for that time, they invite Jahy to their apartment above the pub instead.
Jahy accepts the offer, and suddenly her living situation has been upgraded considerably. Little does she know the manager had been hoping Jahy came around her place so she could dress her up in all of Ryou-chan’s old clothes and then snap photos of her. Like Druj, the landlady wants variety in Jahy’s wardrobe.
The reason the clothes fit now is that even in her child form, Jahy has physically grown since first arriving in the human world. Jahy warns the landlady that this also means she possesses the power to destroy her at any time, but the landlady trusts that Jahy would never do that. And judging from what we’ve seen of Jahy, she’s absolutely right.
Besides, the true destruction comes shortly after the manager suggests she, Ryou-chan and Jahy put their futons together for the night. That’s when Jahy learns that despite her sweet nature while awake, the landlady is an absolute menace while asleep, flopping around like a fish and throwing vicious kicks and jabs. Ryou-chan, obviously used to this, retreats to the edge of the room, while Jahy plans to return to her apartment ASAP.
The post-credits sequence is actually the most significant part of the episode, overarching plot-wise. At first it seems to be a series of running gags where the Magnificent Saurva thinks of various ways to torture and torment Jahy, all while doing good deeds around town: picking up litter, returning a lost girl to her mom, and helping an old lady across the street.
The dissonance between Saurva’s thoughts and actions and idea of herself as the ultimate Evil Bad Guy finally comes to a head when some kind of sparkly benevolent being—who vaguely resembles the Demon Lord and may be her good counterpart—bestows power upon Saurva, and turns her black uniform white.
It’s possible Saurva accidentally became a magical girl, as she’s given the same mission: destroy the mana crystals. In addition to being an interesting twist in Saurva’s fate and potentially setting up the series’ endgame, it’s also immensely funny development to behold.
