Robotics;Notes: Weakest – but not „weak“. [Englisch]

Disclaimer 1: While Robotics;Notes might be mostly known for its anime adaptation in the west, please don’t forget it’s based on a Visual Novel. An anime can only adapt such a limited amount of scenes from a VN that it’s always a pain comparing both mediums. Production I.G. managed to cover the Visual Novel events in an acceptable way, but the show is obviously missing out on a lot.

This review is written with Robotics;Notes in general in mind, so I’ll not foccus on adaptation flaws or where the anime could assumedly have been more faithful. However, I will add my own opinion on it at the very end. I’ll also state right away, that I haven’t yet read the Visual Novel myself as I’m not one of those lucky people who know japanese. Therefore, my knowledge about the source material consists of discussions with people who do, reading up on it and watching videos of the game.


Disclaimer 2: This review picks up on a few events which might be considered spoilers by some people. However, rest assured those won’t take away any key-points of the story and I personally don’t think they will limit your enjoyment of Robotics;Notes in any way. Those parts are simply included because I want to give a genuine and faithful insight into the plot’s premise. Without catching on to at least some events beyond the very beginning, this would not have been possible. While it’s written from the viewpoint of someone who already read Steins;Gate, and ideally also one of the two Chaos; titles (Chaos;Head or Chaos;Child), I tried to keep the review open for anyone. So please feel welcome to read it in any case 😉



Hold up! Sure, I know Steins;Gate. But… Chaos;Head? Chaos;Child? What are you talking about?“

What is "Science Adventure"?

So let’s take a step back for the ones unaware and a brief look on the…

Relation to Science Adventure

As you might notice in this article, I sometimes refer to Science Adventure, or short SciADV. In case you aren’t familiar with it, SciADV is a series consisting of several interconnected Visual Novel titles, including the overly popular Steins;Gate.

Everything started back in 2008 when Chaos;Head came out, and one year later Chaos;Head Noah as a completed, improved release of the original. While Chaos;Head itself focused on the so-called “delusional science”, its concepts layed out the base for all of the later SciADV titles. Steins;Gate came out in 2010, and by being advertised as “Hypothetical Adventure” it didn’t only focus on time travel, but picked up on aspects from Chaos;Head as well. Devices such as the time leap machine or Amadeus are based on Chaos;Head technology for example. Then, the only recently localized Chaos;Child is a direct sequel to Chaos;Head, builds up on its story and develops concepts even further.

Robotics;Notes entered the big picture back in 2012, along with an anime adaption produced by Ghost in the Shell’s Production IG at the same time as the Visual Novel. Two years later an improved edition called “Robotics;Notes Elite” was released, adding 3D models instead of character sprites as well as animated cutscenes.

Throughout all of SciADV there’s a main antagonist called “Committee of 300”, referring to the real-life conspiracy theory by the same name. Already being an important player in Chaos;Head, it continues to be present in Chaos;Child, Steins;Gate and Robotics;Notes. Of all SciADV titles the Robotics;Notes Visual Novel also happens to be the one which contributes the most to the committee lore.

In January 2019 SciADV received its newest entry as a sequel to Robotics;Notes. It’s called “Robotics;Notes DaSH”, and as the suffix implies it adds Daru to the cast. First and foremost it’s a direct sequel to the original Robotics;Notes, but also a crossover title between all previous Science Adventure titles. Therefore it has even more references to Steins;Gate and Chaos; than its prequel, and still continues to rely on their established concepts.




Weakest – but not weak.


Reading Steiner” is not only an important term for Okabe in Steins;Gate. It also refers to the online handle of Andrew Hodgsonone of the Visual Novel’s translators. Besides the main game, he translated uncountable amounts of side-content to Steins;Gate and other titles from the franchise it belongs to, namely “Science Adventure”.

Steiner is a passionate fan of SciADV, and very knowledgeable when it comes to this series. Therefore I would like to start this review with an actually encouraging comment once stated by him:



So yeah, Robotics;Notes. It’s that kind of title I personally always pushed back further and further. And that tweet was ironically amongst the reasons for my lack of interest. While Steiner explicitly stated ‘it’s not a weak title’, in combination with certain images I saw here and there, and hearing about how overly cheerful the story is supposed to be, the words weakest title’ always kept me off. And well… It surely is offering a somewhat more “happier” and “brighter” plot than you might expect from a part of the series.

So… In the end, will it live up to my expectations?“

You’re worried, unsure about what to expect? Especially after Steins;Gate or even more Chaos;Head and ;Child almost got your favorite titles because of their more serious parts? In that case you would be more than a fool to expect Robotics;Notes to be a straight out Slice of Life story.

It still is part of the Science Adventure series, and therefore you will…


…still dive into a fairly dark, twisted plot.

…still investigate a conspiracy theory.

…still encounter the Committee of 300.

…still be reminded of concepts shared amongst all SciADV titles.


In case you’re aware of the Chaos;-titles, the last point might be of particular interest for you. It’s especially true for Chaos;Head, because both titles are related in more ways than one. And there’s a lot more in for you than just a few references.

But yeah, let’s stay objective and somewhat grounded: Yes, Robotics;Notes also features a good amount of lightweight themes and situations. Now I’m not sure how sensitive you are about such stuff, perhaps you don’t even mind it at all and want me to finally shut up already. However the story isn’t just trying to be happier for the sake of being happy. While it attempts to build characters, next to motives and personalities, focus is especially given to how their dreams manifest as “GunBuild” slowly becomes reality. The generally lighter mood helps expressing those feelings a lot, and it would be absolutely unfair to describe it as ‘unfitting’ or even ‘weak’.

The reason why I’m penetrating that point so much is that it’s a common point of criticism when comparing Robotics;Notes to the rest of SciADV. Having been invented as last of the franchises‘ three settings, especially after two already successful prequels, a lot of people appear to be disappointed because it didn’t turn out to be “Steins;Gate 2” or “Chaos;Head 2”. However, Robotics;Notes builds up another world, far away from the ‘hypothetical’ Akihabara or the ‘delusional’ Shibuya. And simply because it’s a bit more lively, and perhaps a bit more cheerful, doesn’t render it inferior to the already established ones. So why not give it a chance as well?


General Setting

Contrary to the urban setting of Steins;Gate and both Chaos;-titles, Robotics;Notes is set on the small island Tanegashima, which is located in the southern area of Japan. The story is actively trying to bring in some fresh air, as many scenes are set in a rather natural environment. Not only does that affect vegetation in a lot of the more urban areas, the ocean is also close-by and relevant for various scenes. On top of that, some locations such as the Tanegashima Space Center, or even organizations such as JAXA, exist in real-life as well.

Time-wise it was supposed to happen in a year which is now present – 2019 – where Augmented Reality technology spread to a lot of handheld devices. Nearly each character owns one of the so-called PhoneDroids (or „PokeComs“), which are basically tablets running what we know as Android operating system. Similar to how it is in Steins;Gate, a player of the Visual Novel is able to use said device to browse Twipo (the in-universe Twitter) or open a map application („Deluoode Map“).

An important part of the whole story, and especially the novel, is also an app called IRUO. It can be described as a multi-purpose Augmented Reality interface, which allows the user to see, add and interact with notices, advertisements, geotags, event triggers and so on. It’s used a lot throughout the plot, and even allows you to actually examine the environment in-game. For example, it’s possible to read up informations tagged on characters or objects.

…and what is it about?

As for the story: In some reviews I saw Robotics;Notes presented as a story about building a robot. Period.

“That seems to be the gist of it, isn’t it?”

Well, that statement is not wrong at all. However it’s absolutely unfair to just omit the fact Robotics;Notes also focuses on a conspiracy theory as backing. That one brings in a lot of increasingly thrilling, shady elements and is more than equally important. As stated earlier, it’s still a fully fledged entry in the SciADV series.


That just as foreword, now really on to what it is about:


It’s time for robots…

As it is in all SciADV titles, the main protagonists are several students. Senomiya Akiho and Yashio Kaito, or short Aki and Kai, are members of their school’s “Robotics Research Club”. While Kai isn’t especially interested in robots, he joined at the request of Aki’s sister Misaki. Since Misaki decided for a career at mainland-based company „Exoskeleton“, she left Tanegashima right after graduation.

Being worried about Aki, she especially entrusted her to Kai with regards to her Elephant-Mouse-Syndrome: A blackout in stressful situations, causing Aki to see her environment “fast-forwarding”. Misaki’s confidence in Kai isn’t all that far-fetched, because he himself suffers from the opposite version of the very same syndrome. Instead of fast-forwarding though, he perceives everything in slow-motion. Both developed their syndromes several years ago, after a mysterious mass fainting on a ferry with the name “S.S. Anemone”.

The overall plot focuses on Aki’s intention to work on a huge robot, namely “GunBuild 1”. Its blueprints and initial construction origin from Misaki herself, however in the end time worked against her. After her graduation a half-finished GunBuild remained covered in a hangar, which served the former club members as headquarter. Pulling off the tarp from her sister’s dream, Aki almost feels pity for the enormous, humanoid robot. And so, being the only club member besides Kai, she puts in her best efforts to avoid its looming shutdown, and to find new members to finally conclude work on Misaki’s “legacy”.


…but there’s more:

As time passes, Kai starts hearing a recurring static sound from his PhoneDroid Pad. It always follows the same pattern: A few short beeps, and then – white noise. And it doesn’t stay like that: It’s not long until he even hears voices from the device’s speakers.

Still lacking interest for Aki’s GunBuild project, he begins investigating those phenomenons. The more he dives into them, the more it turns out there is something strange waiting for him inside IRUO. As a result, Kai is being dragged into an odd game. Its rules require him to “clear flags” by successfully solving quests put up within the AR application, so as to slowly walk down the path of a veiled truth. About which, each time a quest is solved, small pieces of information are revealed to him.

While completing this ominous puzzle, he gradually learns of an obscure theory about solar storms, uncovering an experiment which secretly has been conducted on Tanegashima’s grounds for almost a decade. And alongside, about a person called “Kimijima Kou”, who seems to be deeply involved in it…


What about the characters?

Left to right: Subaru, Kaito, Junna, Akiho. Frau is not present here.

The main cast consists of five persons, and two additional ‘mystery girls’ who better remain unexplained during this review. It may be revealed one of them originates from Steins;Gate though. The female part is made up of Akiho, Junna and ‘Frau Koujiro’, whose strange (and partially german) name corresponds to her online-handle. As for the male part, we should mention Kaito as the main character and least but not last Subaru. The story mostly focuses on Kaito and Akiho, who drive the plot forward. So I want to give a short reflection on at least the two of them, and Frau as well.


As for Akiho…

…she probably is the most energetic person amongst the club’s members. It’s her who continues to push the team forward, so as to reach her final goal. Her motivation is entirely rooted in her ambition to live up to Misaki, and so finishing GunBuild turns into her one and only dream. Even as severe problems arise, she isn’t willing to drop her sister’s construction for the sake of starting from scratch again. Her personality contrasts with Kaito’s one a lot, which also isn’t very healthy for the two of them right at the beginning. It’s not before the club gains its remaining members that Kaito and Akiho are able to spend their time sperate from each other, giving Akiho the possibility to follow her dreams more passionately.


Kaito on the other hand

…is a character who vastly lacks interest for robots, and neither of Akiho’s powerful speeches is able to change that. In fact, the only interest he ever has on the matter is ‚Kill Ballad’, a mech-focused fighting-game. He invests a lot of his time into it, becoming a fairly good opponent for many. As result, he often depends requests on Akiho’s behalf on whether she is able to beat him in a battle, which ultimately leads to her giving up.

Personality-wise Kaito is therefore a rather relaxed, and partially also sarcastic person. Due to his laid-back nature he sometimes doesn’t hesitate at choosing the easy way out by cheating and also reaches levels where he can be quite manipulative. Despite all of that, Akiho is still turning to him whenever she requires support for a difficult decision to make. Several times throughout the whole plot Kaito brings her back on track again as she is in desperate situations, which shows a lot of Kaito’s character appears to just be facade.


Frau ‚Kona’ Koujiro, Frau Bow or just Frau, …

…however she is referred to, is presented as a rather anti-social person right from the start. She was the main developer of Kill Ballad, and spends the majority of her time as a shut-in, locked into her apartment. As a result of her life-style she frequently uses netspeak expressions, refers to Japanese memes and lacks even the most basic social skills. A lot of Kona’s interest is also dedicated to the in-universe anime ‚Gunvarrel’, leading to her not treating persons kindly who talk poorly of the show.

Her personality rapidly shifts between bored aloofness and erratic excitement, which is often filled with loads of pervertedness. In a certain way, Kona might be seen as a female Daru, however she’s a lot more emotional as character. As she’s easily exaggerating, Kona tends to be quite insensitive at times. Such traits even caused Kaito, while normally being fairly calm, to snap at her after she called his Elephant-Mouse-Syndrom an anime cliché.

However Kaito and her still spend a lot of time together, as she finally joins the club as the team’s programmer. And so not only Kaito learns about Kona’s past, Kona also learns about what the depths of IRUO are harboring. It appears as if she intentionally moved to Tanegashima, and Kimijima Kou wakes her interest as well in one way or the other…


Musical style:

Background music

Takeshi Abo, as the main composer behind all SciADV titles, described Steins;Gate’s music as “cloudy” and Chaos;Head’s music as “rainy”. While everyone might come up with their own images about the general mood in both games, I think Steins;Gate portrayed a clean, scientific soundscape while Chaos;Head obviously attempted to capture feelings of fear and anxiety, along with the literal feeling of being ‘deluded’.

Robotics;Notes’ visual core elements are mainly “huge, complex machines” (read: robots), as well as irradiation and radio waves along with a conspiracy feeling. Especially with regards to the fact it focuses on robots, Robotics;Notes attempts to bring in a fairly cinematic, symphonic soundtrack. It perfectly blends with the mech-focused scenes and is a nice alternative to the more synth heavy soundtracks of Steins;Gate and especially Chaos;Head.

Imagine a person climbing up on a swaying tower in the midst of a typhoon. Or the jarring, creaking sound of an enormous robot collapsing. Those scenes accompanied by sharp violins, the threatening sound of a rumbling bass and the violent beats of drums. The OST easily allows more colossal and impactful scenes to take place, of which we have quite a lot in Robotics;Notes. As an example, listen to Hajimaru Houkai – which essentially translates to “Dawn of Collapse”.


Openings and Endings

The (original) Visual Novel’s Openening is called „Augmented Place“, performed by japanese rock-duo „Zwei“:

Robotics;Notes VN OP - Augmented Place - English Subbed

Overall it does a decent job at representing the game, and feels a lot more faithful to the story than its anime counterparts. Still, let’s not entirely forget about those:

Opening- and Ending-wise the adaptation feature’s two different songs respectively. Notable ones are „Junjō Spectra“ (the first opening) by Zwei as well, and „Topology“ (the second ending) by well-known SciADV singer „Kanako Itō“. Especially for the ones interested in the relation to Chaos;Head, I recommend paying attention to the lyrics to Junjō Spectra.


Robotics;Notes is coming to the west!

After months of attempts at raising Robotics;Notes‘ popularity and reaching out to western publisher Spike Chunsoft, Operation HiddenHand (see below) finally reached its goal! Even though the equally desired Chaos;Head NoAH won’t complete the currently community-translated Chaos;Head, we’re in for two entirely new conspiracy theories in the SciADV universe.

„Wait… Did you just say ‚two‘?“

Well, it’s not just Robotics;Notes Elite… The big surprise is: We’re getting Robotics;Notes DaSH as well!

Both titles are going to receive an official localization on PlayStation 4, Nintendo Switch as well as on Steam. This also marks the very first SciADV localization covering a PC (Windows only) version on the initial release day. Contrary to the other SciADV titles, none of the Robotics;Notes games has received a Windows port until this day. This means a dedicated port is happening as part of the localization process.

The release for Elite and DaSH is scheduled for October 13th 2020 in the US, and for October 16th in Europe:

Robotics;Notes Elite & DaSH Double Pack website and trailer available




The following section is outdated, however Operation HiddenHand is still a thing. As the Robotics;Notes announcement leaves us with hope for potential future localizations, you might also want to support the remaining SciADV titles:


Operation HiddenHand:

Instead of an official Robotics;Notes localization, the former publisher PQube brought over Steins;Gate Zero and Chaos;Child. Both of those were highly anticipated titles, and rather obvious choices for localizations of the SciADV franchise. After MAGES. transferred partnership over to North American publisher “Spike Chunsoft”, Steins;Gate Elite and Linear Bounded Phenogram received a western release as well.

As far as Steins;Gate goes, the only somewhat significant title left is “Darling of Loving Vows”, a comedic spin-off Visual Novel. It might be on Spike’s list, but its priority is rather questionable. So at this point we might expect another part of the SciADV series to be picked up by Spike Chunsoft and MAGES. for a release in the west. And realistically seen, the only relevant ones would be Robotics;Notes Elite or Chaos;Head Noah. (Robotics;Notes DaSH is too reliant on its prequel to be localized as standalone, even though it might appeal to Steins;Gate fans a lot more due to Daru being in the cast.) By now, it’s also no secret anymore a group of translators around Reading Steiner translated Chaos;Head Noah in an official capacity years ago. Unfortunately the translation was never released, as the game was judged as ‘too old’ by MAGES. CEO Chiyomaru Sakura.

And this is exactly where Operation HiddenHand comes in. It started as petition meant for Spike Chunsoft and MAGES. to bring Robotics;Notes Elite and as secondary thought also Chaos;Head Noah to the west. Both companies involved stated on various occasions that localizations would be considered depending on the interest, and on last year’s GDC an official announcement by Spike hinted that Robotics;Notes might be included amongst future, localized SciADV titles.

By now operation HiddenHand turned into a fan movement, along with an official Twitter account. Perhaps you would like to show your support as well? Their petition can be found and signed here:



A short commentary:

I wrote a short commentary on my personal opinion of the anime, also covering what bits and pieces of information from the Visual Novel I am aware of. You can read up on it by following the link below:

Robotics;Notes: Weakest – but not „weak“. [Commentary, English]



To give credit to a few helpful sources: (admittedly, I took a few parts for the characterisations pretty much exactly from the corresponding pages to Frau and Kaito)



Thank you!

If you made it this far then I would like to thank you for reading. I don’t normally write reviews, and I’m well aware that this article might not have been the best one. At least I personally think certain points came too short and I should have focused more on ‚why‘ Robotics;Notes is on par with other SciADV titles. But at this point I just lack the motivation to rewrite it all, if I want to be honest. So in case you still enjoyed it then I’m glad, in case you didn’t then you probably didn’t even read this far. No matter what, I hope awareness of Robotics;Notes continues to grow in the west. And perhaps this article woke interest in at least a few people who might not have known of the title 😉

Autor: Ghost in the Silence

Ever since late 2015 I've been following the Science Adventure series, and recently decided to write up an article about the weakest, yet not "weak", entry of the series: Robotics;Notes.
