ChäoS;HEĀd NoAH, Science Adventure Series #1, is a complete version of Chaos;Head PC (which I read years before this, meaning that the common route of NoAH was like a reread for me).

It is a very ambitious work, and a bit risky in some aspects. It's ambitious due to how many various concepts it juggles and the different directions the routes go into. It's risky due to Takumi not being a surface-level likable protagonist, character or person.

It goes into varIous sci-fi concepts such as various scientific and philosophical ideas of reality being what you you perceive it to be, gigalomania, interdimensional concepts, and more. Thematically, though, all of it connects back to the main theme of "you love yourself NOW", which, while not being the most original (I'm sure anime-related media consumers can think of several stories that go over this), is executed very well and provides many, many different examples and way this can be applied.

Takumi is beyond awkward. He is socially inept with other people, barely getting a word in, while in his thoughts or when he's alone in his construction container of a room, he mocks others. He jumps to conclusions, and is insanely paranoid. It even turns out that he's not an ordinary human being either. Driven into despair and at a loss for what to do, it's this kind of protagonist, the opposite of the gallant and likable heroic figure that you might often see, that is perfectly suitable for the messages this story tries to communicate.

The vibe in this is great. The feel of the city is palpable, and Takumi's paranoia and the reader's becomes one.

The NoAH routes are a great addition for the most part, barring Yua's and Nanami's routes. For the former, it's very unambitious unlike other content in the VN, and Nanami's just felt very mediocre. The other three are amazing, though the issue that I have with SciAdv as a whole starts to seep through the cracks in Sena's route. It's still good, though. In addition, I didn't really like how you had to repeat ending A/AA's finale for the true ending, but it still hit hard.

So what are some issues I have? Well, it is quite often boring, and sometimes it goes over the top with Takumi being disgusting, especially in negative delusions. Kozupii's route also went over the line in one aspect. And the aforementioned Yua and Nanami routes aren't impressive.

Overall though, very cool.

Been meaning to get to this as I did play Chaos;Child a while ago and liked it quite a bit, though can’t actually remember if there were specifics about Chaos;Head’s story to spoil much about it at least. I also played this with the Committee of Zero PC patch, as the official version is apparently so poor it was highly recommended to have it installed as a fix before playing. But was easy enough to get working and didn’t notice any issues with it

This VN was uhhh… good I guess. I think this was definitely more horror esque than I recall from Chaos;Child, mainly due its focus on fear and paranoia. I can understand why this one is more divisive than others in the SciAdv series, as whether you like it or not probably depends on how much you can tolerate the main character Takumi, an immensely pathetic and delusional shut-in, and the game very much tries to make him as unlikable as possible. While I don’t mind the idea of a protag like this, I feel it goes too far with this to the point where it just got exhausting to follow him, and his frequently perverted delusions/dialogue was really not it for me. But will say it was compelling to watch how badly he falls apart as the story progresses

Speaking of, delusions are basically the main mechanic of the game and you choose between a positive or negative one. Though for the most part didn’t really care for this, as for the first playthrough it has no bearing on the story aside for seeing some minor scene changes (Chaos;Child was like this also I think). This changes after you finish the first time and I think leads to the different endings depending on what you choose (though I don’t see how you can get those without a guide tbh), but note to get the true ending of the game you have to get every other ending first, which basically means you’ll be restarting the game and fast forwarding through over and over. The skipped text will also keep getting interrupted by the delusion prompts each time which got tedious

As of now I think I prefer Chaos;Child, but I might get around to replaying it to better compare and use the PC patch it has also. Chaos;Head’s an interesting horror VN, but do feel as the first in the series you can tell where its successors refine on it a bit more

my creepy laugh kind of annoyed me, so i kicked the plastic bottle at my feet.


While the atmosphere, mystery, and general sense of unease during the first few hours was enough to get me interested, Chaos Head never really capitalized on those elements in a meaningful way. The mystery never actually goes anywhere, the tension in the atmosphere soon gives way to some sort of shitty chuunibyou power fantasy, and none of the ideas or concepts at play ever get more than a surface level analysis (and most don't even end up mattering to the overall narrative).

Very little of what Chaos Head does past its first 3-4 hours really felt worth experiencing. The delusions are painfully underdeveloped as a mechanic and just feel like a way the game can do whatever it needs to move the story forward, the side characters may have one or two interesting aspects about them but rarely contribute in a meaningful way outside of the one chapter where they play a role, and the main character's schtick of being a paranoid shut-in is interesting at first but quickly runs out of steam.

But what brings this from mediocre to outright bad is just how badly Chaos Head manages to botch its pacing. The game has its two main routes (though one is essentially just an infodump for clearing up loose ends that never got explained elsewhere) as well as an additional route for each of its heroines. You need to get through all of these before you can unlock the true ending, effectively requiring 8 playthroughs. But the game makes doing this such a monumental pain because of how they are spread out.

The two main routes are simple enough. You just gotta get through the story and make specific choices each time. But what's especially annoying is the 6 character-specific routes since the point at which you 'enter' a route is near the very beginning of the game but everything is the same until quite late into the game, meaning (barring a small handful of extra scenes) you need to spend 20-30 minutes per route just skipping through text you have already read. And this is made even worse by the fact that the skip function is very finnicky, stalling the game whenever it reaches a choice, often not skipping certain voice lines for unclear reasons thus slowing down the speed at which you can get through the game, and refusing to skip certain scenes entirely because one line changed even though 99% of the scene is exactly what you've seen before.

Put that together and you're looking at around 15% of your total playtime being nothing but skipping scenes and a very large chunk of the rest of the story being very poorly paced for other reasons. Get through all of that and you can finally get to the true ending... which literally turns out to be one extra scene that adds no meaningful details about anything that happened in the story. I genuinely feel like 15 hours of my time was wasted in the hopes that something towards the end might reignite the interesting stuff the game was doing at first. Some sort of twist or extra detail that might compensate for the game's other shortcomings. But that was not to be.

So yeah... I wouldn't bother. The few areas that Chaos Head did well never really mattered while its flaws grow ever worse as the story goes on. I really can't think of a good reason why I might recommend this to somebody because even somebody who is interested in the premise and has low standards for everything else would still probably walk away disappointed.

There's something very steady about this game which makes it fine but the more I sit away from it...after doing all the endings...the more I feel like it was a game that went through the motions with some interesting concepts but just felt rather emotionally flat. Which isn't great when you are playing a visual novel since you don't really have other things you are doing to engage you. In a sense I'm torn between rating this higher and lower and ultimately settled in the middle because

Things I liked
-Presentation in terms of visuals, animation and sound effects. they definitely spent budget here. voice acting also excellent.
-Chapter pacing. No chapter felt overly long.
-Not "redeeming" a character just because they are supposed to be on the "good guys" side for the most part.

Things I disliked
-Without saying too much, half the cast, even in their own routes, don't feel really developed. I only ended up caring about one of the 6 girls. 2 were developed okay but I didn't care for them. 3 did have their stories but it also felt like they were there for the count.
-The true ending. I did not like it. It doesn't help that I didn't like the girls' routes that much, except for one.
-Just in general. Like I didn't hate the creepiness of the otaku main character but it also really didn't feel like it had a point emotionally.

Funnily enough I liked the "worst" of the endings the best. Maybe because that's just how I saw the protagonist.

"Don't expect a masterpiece like Steins;Gate"
No, this is better

O Takumi é tão bom que eu sinceramente queria que ele estivesse em uma obra mais consistente (não que eu tenha desgostado de Chaos ou coisa do genero, mas é que o Takumi pra mim ao menos ta em um patamar de qualidade um pouco acima do resto da obra)

melhor que subahibi

Chaos;Head Noah was just a miserable time for me from start to finish. It is ambitious in a way, and there are some enjoyable moments, but ultimately the game fails at just about everything. First of all, the main character is probably the worst protagonist I have ever seen in any media whatsoever. Not simply because he is an incel, but because the game never comments on anything he does or just in general, has anything meaningful to say about this type of personality disorder. Side characters are as bland as possible and most of the time they just serve to drive the plot forward. The story in itself is basically just pseudoscience that never establishes any rules on how this pseudoscience functions, meaning that the game can basically pull anything out of its ass if it wants to. Also, sexualizing minors is a fucking no-go, regardless of the country in which this game was developed.

I really enjoyed delusional and paranoid part of this game, it's really unsettling and you along with the protagonist really don't know what is coming next. It's true psychological terror. When it gets to more action scenes later it gets more cheesy. I also wish true end was more in depth.

I played the original version a couple years back and I enjoyed it despite some pretty big faults in my eyes, so I was curious how this enhanced version would hold up since I had played a large chunk of the content already. Ultimately my stance was pretty solidified without much change, this game has some really awesome plot writing (it would be spoilers to get into it too much) but is hampered by a pretty bland supporting cast and a truly obnoxious main character that takes way too long to become even partially tolerable. The Noah additions to the game are a highlight though, it makes the side characters a bit more fleshed out and interesting for the most part which is appreciated. Ultimately the super dark murder mystery and crazy sci fi elements make this a good story overall but the character shortcomings keep it firmly in last place in the franchise for me (DaSH didn’t happen).

Whose eyes are those eyes?

This is the first SciAdv VN I've read and the only one so far. The storytelling is gripping; you do find yourself pulled into the mystery. Of course, your conclusions and expectations are unlikely to be met, but the climax of C;H is satisfying nevertheless.

This VN looks absolutely awesome on the presentation at the point it makes me wanna play this than Higurashi/Umineko (which, I know, are peak, but let's face it: the presentation in the original/Steam versions has barely any budget unlike Mages Inc.'s games).

I'm about to go out and get some McDonald's, today is such a joyous day :)

they were feeling extra spicy on the nanami route

The very definition of pathetic. It is a constant vicious cycle exercise of self-hatred screaming "I'm sorry for what I am" while regurgitating on the otaku culture that it is so ashamed to belong to. Obviously, neither aspect is remotely well done (though I must admit that the beginning may deceive to think that the game has anything to do, which ends up being revealed to be the worst smelling kamikaze dumpster of fire) and there are some outlines of what the game wants to really do without shame (not to confuse with competently realized, the sci-fi leaning segments hint on what I hope the developers set out to do in further games that ends up being anecdotal in here, the most common storytelling segments regarding more conventional tones like suspense and horror can only be complemented with mediocre when most inspired). This is a game so disgraced that despite its obvious yearn to show the most degenerate and repulsive imagery as part of its critique/fascination self-conscious ironic contradiction it may be one of the few games published by Nitroplus, one of the biggest names on the VN industry that hasn’t yet heard of the word “delicacy”, and come out without even one hentai scene resorting to ridiculous and even more disgusting placeholders instead.

At times, I feel sorrow towards the people who made this, just as they want you to feel some shame for their otaku beyond salvation misogynist walking dirtbag of a protagonist. At the end, both unapologetically embrace the mess of their own heads with so little thought that I just stop caring.

Nishijou Takumi is literally me.

unironically the only character that was enjoyable to have on screen was misumi

the only good writing was the narration of takumi in the horror sense of being seen with the whole whos eyes thing. takumis depiction of anxiety was pretty okay, the nanami ringtone scene in his room with the hand was definitely really, really well executed, so much that i'll give this game an extra star (2 in total, wow!)

many of the elements of the games story cater to a 12 year olds fantasy.. or fat people who live in their moms basement and unironically use terms like waifu

terrible main character. the attempt of redeeming him after 15 hours of torture is pathetic. plot is almost interesting but.. cheesy with all the swords and stuff. so unnecessary. terrible pacing throughout the chapters. weak ass plot twists too

just play steins gate instead. this is not worth playing if you are interested in intricate fiction, for the time investment of a visual novel, it sucks.

though i finished one ending, i don't think i even want to play the other endings. also put me off playing chaos child.

seemingly pivots its unhealthy painting of CHUUNIBYOU-ISMS and such as actually totally alright and not worth examining at all. shut up and wield your magic sword; there are pretty women out there who LOVE YOU for no reason!!!

it's all fun and games about getting into the headspace of a real anxiety ridden, delusional NEET boy and maybe identifying we should better ourselves..... at least until the thing decides to just LOSE its fucking mind and totally forgoes that potentially relatable human feeling shit for an unironic power fantasy about ACTUALLY saving the world from evil mind-control corporations.

seriously tho??? even when the story already SHOWED US just how stupid it sounds to be so paranoid and self important thinking????? It WASN'T ironic??????? what a fumble...

i think every so-so vn I've ever read has been bolstered up a few points now that I have this real nothing burger of an experience to compare to. you are NOT valid in your delusions, kids. grow up and learn how to talk to people. please!

So I beat the normal endings back when the CoZ patch came out but I just went back and finished all the bonus routes and got the true end so I feel better equipped to do a real review.

This game is an absolute mess, a weird and wild patchwork of edgelord horror tropes, evangelion-level psychobabble, bishoujo stereotypes, and straight up magical girl anime nonsense. It's excessive, and it's kind of embarrassing, like peeking into someone's journal of half finished fanfics. And yeah, I love it to pieces.

What I love about the VN space is that I just can't think of any other genre that could get away with something like this. It is, straight up, a psychological horror game, but it's also a game where a bunch of anime girls are inexplicably drawn to just some fuckin' dude and wield psychic swords borne of their own traumas. For all intents and purposes, this shouldn't work.

But it really, really does, and I think that speaks to level of craft on display here. This game has an impeccable sense of mood and atmosphere, masterfully wielding sound design, tricks of prose, and sudden edits to make the fairly rudimentary silicon graphics presentation utterly envelop the reader. When the game had me, it really fuckin' had me, in a way that few other horror VNs manage as well.

I also think that focusing the story on Takumi allows the story to both comment on its own excesses while giving us the insight to empathize with a genuinely awful dude who, if we're being honest, we at one point had more in common with than we'd like to admit. The fact that most of the early delusions come from a wastoid otaku has the neat effect of making the later story developments actually feel grounded by comparison, and the delusion concept itself allows the story to play with fire without (usually) burning itself.

And the way the game has empathy, but not sympathy, for Takumi is genuinely compelling. He's an awful, selfish, shallow guy, who is also deeply traumatized and dealing with a severe and debilitating anxiety disorder, and the game allows both to exist simultaneously without one overwhelming the other. People are complicated, and you really never know what they're going through, for good and for ill.

That's not to say this game always succeeds. This is the first of the SciADV games and it gives the impression that the writers were afraid they'd never get to do another, because it throws everything at the wall. And, especially with 6 routes added by Noah, not all of it sticks. Sena's route is dull and of interest only for the lore-heads; Nanami's is a complete waste of time; and there are several chapters that, upon revisiting, have that Kojima monologue feeling of "hey, wanna hear something cool I read on wikipedia?"

But that all said, I'm glad I came back and fully finished the game—the extra character development really does add some depth and edge to the game's bishoujo critiques, and Rimi's route is genuinely some of the best written material in the game. The impression I've gotten from the community is that this is thought of as the worst of the series—if so, i'm stoked to see what's next.

waited 5 years to read C;H Noah which is similar to the OG but only adds additional character routes that sorta flesh out the characters. was a bit let down but makes me more excited to start A;C!

A rota da Nanami e da Yua é uma bosta, a resolução do murder mystery é ruim e os vilões são terríveis.

De resto impecável o Takumi é um dos melhor personagem ja feito

Route Ratings:
Silent sky: 7.5/10
Cry Sky: 6/10
Nanami: 5/10
Yua: 2/10
Ayase: 7/10
Kouzupii: 7.5/10
Sena: 8.5/10
Rimi: 8.5/10
True: 7/10

This game is definitely not for everyone.

But it certainly was for me.

I really don't know... I just loved this VN.
I played through every route, got every ending and all the achievements for it.

I just loved it. I am so happy with my introduction to the science adventure series and I'm super excited to continue on with the rest of the series.

I've literally just finished the game so I'm still reeling a bit from the true ending and just wow.... I wish I could express jus how much I've enjoyed this game but I need some more time to formulate my thoughts.


I played the original many years back as a teenager, it was cool, quite scary for a kid. Nowadays as a full fledged NEET, the game just hits different, relating to the paranoid Nishijou Takumi is not cool by all means, but his messed up head and personality make the whole experience so much better. Mastering the game was awesome as well ESPECIALLY for the True Ending of the Game, it gave me the chills "Sakihata Rimi Inoru". Long story short, the game is a very close experience to putting your feet in the ocean of insanity and paranoia.

Pulling the plug at chapter 7. Easily the most insufferable protagonist I’ve ever encountered in any format of storytelling. The underage characters are empty and over-sexualized, the writing is amateurish, and the plot is meandering and boring. Upset I actually wasted so much time waiting for this to get better.

Absolute peak, Takumi is just like me, characters route are kinda meh and you can't really grow affection for said characters
