With the premise set up out of the way, this episode is able to cut loose and actually have some fun with it. This is largely accomplished by bringing Emilia, the hero from the last episode who forced Satan to Earth in the first place, into the fold.
Where the demon duo have adjusted to life on Earth fairly easily, the transition isn’t quite so smooth for the hero. It’s played for laughs, which makes for great entertainment, but it also helps build up sympathy as she quickly falls into the role of “woobie”. It gets to the point that even Satan starts to show her some sympathy later on in the episode.
The dynamic between the two also makes for great comedy. The enmity between sworn enemies, when transferred to Earth, becomes a lot more petty. True, Emilia does come at Satan/Sadao with a knife when the episode opens, but reality ensues and the police intervene and write it off as a lover’s quarrel.
It only goes downhill from there as Emilia gloats that she destroyed and discarded the umbrella that he had given her last episode when he insists on getting it back. The favor is returned, though, when she appears at his apartment to kill him, only to find herself locked out, begging to be let in.
Her attempts at recon go about as well. The episode has quite a bit of fun with this, as she’ll hear Sadao and Alciel/Shiro talk as if they’re about to enact some nefarious scheme, only to reveal that they’re doing something completely mundane.
It gets to the point where Emilia becomes convinced that Satan is content to live a quiet, peaceful life on Earth. She even offers to just let him be and return to Ente Isla, since there’s no point in killing him like this. It’s a pretty big character moment for her, all things considered.
As he had earlier in the episode, though, Satan declares that he is still a dark lord and intends to conquer both worlds. It’s an odd play when you think about it. True, it maintains the status quo and reaffirms that Sadao is, in fact a villain, but from a tactical standpoint, wouldn’t it have been better to lie and take her offer to live peacefully? She’d be gone, leaving him free to take over. From there, he’d have a much better stronghold to facilitate taking over Ente Isla. It’s not a deal breaker, but it is a head scratcher.
While the episode certainly has a lot of fun showcasing the disparity between the two leads’ epic fantasy struggle and the mundane day to day existence of life on Earth, the weight of the prior is never completely tossed aside.
On the contrary, it ends up being a prominent plot point as a mysterious assassin attacks the two with magic bullets, suggesting that someone else came through the portal. It adds a nice element of mystery and tension to the largely comedic proceedings.
All in all, this was a really fun episode. The writers were allowed to flex a bit more, leading to stronger interactions and better comedy. I’m looking forward to seeing where things go from here.
