Lemme just preface this review by saying that this is all my opinion and is in no way objective truth, I've seen the ratings on this show and they're garbage. This is just the way I perceived and managed to enjoy this show

I somehow ended up enjoying this more than the actual fully animated show. The comedy hit better, the ending was more impactful than any of the scenes where they try to get emotional in the actual anime. I really can't explain why the fuck I liked this so much. All I can say is that I do genuinely recommend this to people who've already watched the entire show.

This whole thing's animated in flash, which you'd think would take away from the entire experience but it somehow doesn't. Ngl Nyaruko just works better as this type of show imo. Not a harem, just flash animated comedy shorts.

I'm gonna start getting into "spoiler" territory now, even though this isn't the type of show you can necessarily spoil. The ending is foreshadowed at the end of every episode, saying that the extinction of humanity is coming, hinting at a very bleak ending to this genuinely funny and lighthearted show. I would've liked for them to go farther than they already did but beggars can't be choosers.

Nyaruko as a whole has always given me a feeling of there being something behind the curtain, the animated show less so but nevertheless it was still there. I may be overthinking it but I feel like the author intentionally put Kurei out of the spotlight for most of it, while still giving her enough character moments for you to be able to piece together her thought process and why she does what she does throughout the events of the show.

This version of the show, however, is extremely upfront about trying to keep you in the dark. The ending is genuinely inexplicable and really bleak when you put enough thought into it. Nyaruko tries to be reassuring to Mahiro, she embraces him, tells him she loves him, and leaves, presumably to go fight some cosmic horrors. But, the countdown at the end of each episode implies the extinction of humanity, so clearly nobody got their happy ending, which is actually really refreshing when it comes to this series.

Nyaruko has always followed the same pattern in terms of how the situations are handled: foreshadowing early on, build-up of the crisis ahead of them, and finally the stupid, comedic resolution. They even acknowledge this pattern in Nyaruko W, but them acknowledging the pattern doesn't take away from the fact that they had never dealt with a serious problem in a serious way until the latest OVA of the series.

Overall it's just really weird to see just this random, nonsense humor show have that kind of depressing ending. I would've loved to see it get expanded on but that's likely not going to happen as, if and when we get a season 3, the anime likely won't adapt much from this show, despite the latest OVA introducing us to a character from the flash animated show, Atoko. As I said, the show doesn't deal with actual serious situations in serious ways until Nyaruko F so I doubt they'll actually make the apocalypse happen in Nyaruko.

But, there's always a chance. I'd love to see the "plot" of Haiyoru! Nyaruani gets adapted into the fully animated series.
