Necronomico no Cosmic Horror Show

Miko Kurono is a lesser-known streamer, "Necronomico," who plays video games for her small audience. She has been covering the hospital bills of her close friend and fellow streamer, Mayu Mayusaka, ever since she and other popular streamers mysteriously fell into a coma three months ago.

Desperate for money, Miko agrees to participate in a top-secret beta test for a cutting-edge VR game. After clearing the first level, she and six other streamers come face-to-face with the Old Ones—ancient, evil gods who have returned to take over the Earth but are currently trapped inside the VR world. Miko becomes enraged when she discovers that one of the gods, Cthulhu, has taken the likeness of Mayu and is the one responsible for her condition.

Alongside the others, Miko is now a part of the Old Ones' twisted game called the Cosmic Horror Show, where the elimination of all the players results in humanity's doom. However, knowing that the winner is granted a single wish, Miko sets out to beat the game and save Mayu.

Preliminary (5/12 eps)

My personal criteria goes as such: brush and easy to anger girl protagonist, check. Majorly female main cast, check. Loads of nasty examples of human character which anger me to no end but also that for me is like a chili curry for a spicy food lover. Check. And the absurd chaos of whatever is going on that somehow fits very logically into the overall premise. Check.

In fact, and this is just my experience so don't @ me, watching this reminds me of 2013 and watching Kill la Kill, but without Trigger's insane animation and without the, uh, sheer nakedness of it all. Although there ... is at least one character with a huge bouncy chest and a thong that's holding on a prayer, if that's something you can't live without in your anime. "What is left then" - well, the combination of a determined angry yelling girl protag, the starting plot structure of "a bunch of overpowered enemies whose games you have to play if you want to achieve your goal but be warned the rules are WHACK" and the frequent "yes, and" the plot seems to play with itself.

Animation is completely fine by me - it may not be an action-y masterpiece, but it gets the job done. The occasional 3D CGI wasn't too offensive to me either, most of it fits well contextually. The acid brightness of colors adds to the chaos, I dig the exaggerated facial expressions a lot and the general designs of characters are very pleasant to my eye, somewhat unconventional proportions included. The only thing that kinda pulls me out of it sometimes are the squished side profiles. Weird choice of style on that part.

Voice acting is stellar. The writing so far is fast-paced, but not overly so. They have time to shoe in flashbacks to flesh out even episodic characters, so they're doing fine in my book. It also feels like the plot is still gearing up to go full throttle, which is about time considering there's only 12 episodes.

Excited to see where this goes next, may have found my personal anime of the season. Leaving it at 7 for now, 'cause I reserve the highest scores for animes that really shook me, but I will say this has potential to rise higher considering the topics that are getting introduced.

Mixed Feelings

Necronomico no Cosmic Horror Show: a story with potential that ends up going nowhere

I started watching this anime attracted by its curious character design and color palette. And although the story seemed to have potential, I feel that after watching all 12 episodes, it ultimately went nowhere. Don’t get me wrong, this anime has some good aspects, but not solid enough to fully recommend.

The good:

A unique character design and color palette.

A story with potential, trying to show how ancient gods use virtual reality and the internet to conquer and destroy the world.

... A soundtrack that does its job well.

Some interesting characters (mainly Kanna, who basically tries to “carry” the anime on her own).

The bad:

Despite the interesting character design, the animation quality is not great.

Many plot holes in both the story and characters that negatively affect the narrative.

While there are some interesting characters, others fall completely flat. Eita, for example, could have been a compelling character with better development, but he ends up wasted. Even Miko, supposedly the protagonist, only starts to get some development in the last two episodes… and it leads absolutely nowhere.

The anime is so poorly balanced that Kanna ends up feeling like the real protagonist, and honestly, she’s the only character who had proper development throughout the story.

Necronomico and the Cosmic Horror Show — A balls-out-of-the-wall idea that has potential but gravely missed the mark.

Look, I get it; we all do: original anime is pretty much a "high-risk, high reward/return" kind of investment that very few companies today would try to offer something that's different than what the AniManga space has in this day and age, all because of one thing: money. And while some will succeed and some will fail, there's but one entity that pretty much carries this philosophy all around: CyGames, the company behind IPs such as Uma Musume: Pretty Derby, Rage of Bahamut, and Granblue Fantasy, to name ... a few. In fact, CyGames has been knocking around for the last decade or so making anime adaptations out of their mixed-media IPs and are still proposing ideas left and right for the next big thing. Many will say that this is quite the danger because of the high risk-return methodology, but while there are times we can praise them for originality and ingenuity, as is the case with last season's Apocalypse Hotel, others have failed in pretty much the same regard, as is Necronomico no Cosmic Horror Show here.

A VR game project parading around as a survival game of sorts — that's not what the show's MC, Miko "Necronomico" Kurono, is after, and her days of living off her dream as a livestreamer, as much as it is reality, are also the people that she regards as being close to her: the beauty livestreamer influencer Mayu Mayusaka, who ended up being a victim of this game project that involves cosmic beings wanting to take over the world by way of a company promoting VR games at the same time to infiltrate and share the wealth of torturing Earthlings just for their amusement. Alas, as forced as this sounds, it ended up being a trap that would see Miko, alongside other influencers and colourful figures that, like her, have to survive the infamy of the Cosmic Horror Show that's hosted by the Great Old Ones, while putting their own SAN-ity on the line. Lose it completely, and like SAO, they die in real life.

Sure, you might be thinking, "Why would I want to watch a show where it's basically seeing people compete in a Fall Guys-like setting, not to mention how the anime was screwed from the get-go, no thanks to Crunchyroll's incompetency experimenting with AI subtitling?" I'm not going to sugarcoat things: it's exactly this double-whammy culmination of things that are, for the most part, foreign towards anime logic, and at least CyGames tried their hands on this idea that just sadly didn't pan out well for the series to come, which is just your stereotypical strategy game in the vein similar to Summer 2023's Liar Liar and Spring 2024's Kami wa Game ni Ueteiru. a.k.a Gods' Game We Play. And as much as the series past its controversies started stabilizing itself to present the pretty-much familiar game survival story, I'm afraid to say that the show's no better than when it started, with strange games and death-defying stakes attached to it for a "winner takes all" survivability rate, alongside characters who are, for the most part, one-dimensional characters so focused on what they do best to help others ascend to finish the race of saving humanity (which spawns some good moments at times) or defecting to the cosmo's side and indoctrinating fellow humans as an egomaniacal, egoistic way for a win-lose outcome.

When all is said and done, it's just no different than your below-average psychology-level "war games" that just pit both aliens and Earthlings against each other for world domination, which this simple premise and outcome itself might've been too ambitious from the get-go.

Say what you want about the production, it's going to overwhelmingly take the majority out of the experience (especially from the get-go with Episode 1's depiction of Fall Guys) and the usual 2D support from thereafter to keep the survival games going. Studio Gokumi is an alright pick for this one, though it's much in an experimental phase trying to depict Fall Guys-like 4D games that just didn't pan out so well. Even the OST itself feels lacking, while the OP/ED songs themselves, sung by VTubers, are just decent to OK but definitely forgettable.

CyGames, it's a good try with what you've created with Necronomico no Cosmic Horror Show, but the anime probably came out way too harsh with the overtaxing and overcomplication of ideas that depict a survival game show. A good effort from everyone involved with this original anime project, but this is just not it.
