Chaos;Child is a visual novel by 5pb. and the fourth installment in the Science Adventure Series. The game was first released for the Xbox One in 2014 and later released for the Vita, PS3, PS4 and PC.

The PS4 and Vita versions were localised for release in North America and Europe in Q3 of 2017. An english patch for the PC version was released by the Commitee of Zero group in July 2018 and the game got an official Steam release in 22th January 2019 (The Commitee of Zero patch also works for this version and fixes some bugs and translation mistakes)

An anime series produced by SILVER LINK. started in January 2017. The first PV for the series can be seen here. It's licenced for streaming on Crunchyroll and Funimation with the latter providing a simuldub for the series.

The story is set in Tokyo's Shibuya district in 2015, 6 years after the events of Chaos;Head.


Takuru Miyashiro is a high school senior and president of the school's newspaper club whose family died in an earthquake 6 years before. Accompanied by his childhood friend Serika Onoe, foster sister Nono Kurusu, newspaper club members Hana and Shinji; Hinae, an eyewitness to a murder; Uki, who has spent years isolated from the world; and Mio, a misanthrope who has been sent in to aid the police. They all deal with the bizarre events referred to as the "Reincarnation of the New Generation of Madness" (or the New New Generation murders) while also using the superhuman powers that some of them possess.

Like it's predecessor, the game uses the "delusion trigger" system where the player can opt to view one of Takuru's daydreams/delusions. Additionally, the "Mapping Trigger" system is added in which the player uses their own wit to match clues together in the ongoing investigation of the "Reincarnation of the New Generation of Madness".


Chaos;Child provides examples of:

  • The Anime of the Game: The original game was released on December 18, 2014 and the anime aired in January 2017.
  • Adaptation Distillation: It takes about 50 hours to complete the entire game as well as the true route. The anime however adapted this story into merely 12 episodes and an OVA. Just like the C;H anime this adaptation is considered to be mediocre at best despite being loyal to the source material.
  • An Arm and a Leg: The first murder of the game, Yuuma Ootani, had not only cut off his own arm, but eaten bits of it without knowing.
  • Arc Words: Much like Chaos;Head's "Whose eyes are those eyes?", but instead it's "Those eyes are God's eyes". They don't really mean anything, though.
  • Because You Were Nice to Me: Takuru was given the RV in the homeless park because he, along with the rest of Aoba Dorm, helped them out.
  • Big Bad: Three. Shuichi Wakui, a teacher at Hekiho and an agent for the Committee who wants to clean up the appearance of Chaos Child syndrome and the partial Gigalomaniacs after the earthquake, Wataru Sakuma, Miyashiro's foster father and a former member of the Committee who wants to have fun and continue his experiments on Gigalomaniacs, and Serika Onoe, childhood best friend of Miyashiro who wants to give him what he wishes for.
  • Bittersweet Ending: The True Ending. The mastermind of the murders has been more or less dealt with and Senri, Hinae, Hana, and Uki are shown to have been cured of their Chaos Child Syndrome and are living happy lives whilst Serika gets a chance to live a normal life. However, Takuru is being taken away by the police and put in isolation due to his role in the New New Generation murders, Serika seems to be remembering what she's done and Wakui (and by extension the Committee of 300) is still out there.
  • "Blind Idiot" Translation: The official English translation is full of name errors and typos much more than a normal VN would be expected to have. It notably uses the wrong names in some places. Fortunately the Committee of Zero patch fixes all of these issues and even edits untranslated CG/images and backgrounds.
  • Continuity Nod:
    • The earthquake and the white light from Chaos;Head are major plot points.
    • The second coming of the New Generation Murders.
    • Senri's mother is a member of the Cosmic Church of the Divine Light.
    • One of Hana's online friends in her game Ensue 2 is Neidhardt a.k.a. Takumi Nishijou. He even helps her understand her powers and helps her and Takuru avoid Wakui and the Committee during her route.
    • Kunosato Mio appears for the first time talking in English with someone called Chris, later she gives instructions to Takuru and his friends to flee to Akihabara, where her quirky hacker acquaintance can keep them safe.
    • Gunvarrel appears in a poster.
  • Cool Old Guy: Gen-san, an alcoholic hobo who's friends with Takuru and claims he's a decedent of royalty. He's also more or less the leader of the section of the homeless park he lives in and shows himself to be very capable when needed, despite being drunk all the time.
  • Dead All Along: Nono Kurusu.
  • Dead Person Impersonation: The real Nono Kurusu has been dead since the earthquake and Senri Minamisawa had taken on her appearance, unintentionally though.
  • Death of a Child: Takuru and Nono's foster sister Yui ends up a victim of the murders, being killed and dismembered by a mind controlled Shinji.
    • Uki, who is Yui's age, dies in her second good ending.
  • Distressed Dude: Takuru of all people ends up being completely useless in Kazuki's route. It's no exaggeration to say that he could be killed along with the pyromaniac and nothing would change.
  • Downer Ending: Both of Uki's endings, as well as Kazuki's, though the latter ends on a high note despite outright saying the world is their enemy a few lines before.
  • Evil All Along: Takuru's foster dad Wataru Sakuma and his club's advisor Shuichi Wakui are both members of the Committee of 300 and were heavily involved in the conspiracy, the former being the one who helped in committing all the murders, with the one who orchestrated them being Serika Onoe, Takuru's childhood best friend.
  • Even Better Sequel: Regarded by many as the best entry in the Science Adventure franchise.
  • Evolving Credits: The anime's opening changes Nono to appear as Senri following Episode 8.
  • Foreshadowing: The anime has several clues leading up to the reveal of Nono's true identity as Senri Minamisawa. The most obvious being a flashback in an early episode where Senri is seen next to Nono's dead body. Later, Hinae's ability reveals that 'Nono' is lying about having seen Senri die in the earthquake (because it was actually the other way around).
    • A lot of Takuru's delusions tend to get a comment or portrait change from Serika if something weird happens in them. She makes these comments not because he says something, but because she can read his mind.
  • First-Name Basis: Takuru is on a first name basis with the other residents of the Aoba Dorm, and his switch to calling Nono by her family name instead is a point of contention between them throughout most of the game. He later does the same to Uki when she first joins the Dorm. Unfortunately, possibly due to this only being talked about once by Nono fairly late in the game, the game’s translation is inconsistent on which name he uses for Uki despite being consistent for Nono. He even refers to her as Uki within lines of the scene where he’s asked to stop calling her Yamazoe, making it a very jarring request.
  • I Read It for the Articles: In one of his delusions, Takuru claims to read Cool Cat Press for the normal articles rather than the more questionable content. Though considering even the normal articles are still about things one would be embarrassed to talk about and full of misinformation that Taku ends up taking to heart, he's still pretty embarrassed at the thought of even Serika figuring out he reads them.
  • Living Lie Detector: Hinae's ability, which is being able to spot lies with absolute certainty. Though there are multiple ways around it, as proven near the end of the common route.
  • Mass Empowering Event: The white light from the Shibuya earthquake created multiple gigalomaniacs.
  • Multiple Endings: As per most visual novels. In an interesting case, you're forced to go through a specific route that acts as Serika's route first before you're given the options to go through either Uki's, Kazuki's, Arimura's, or Nono's routes. Uki is particular noteworthy, as her route splits from the common route later on and has a total of six endings, two good and four bad, instead of the normal one good/bad ending Kazuki and Arimura have, or the one Nono has.
  • Orange And Blue Morality: Serika doesn't have a normal sense of morality, with her only view on what's "right" being that Takuru is interested in something. Kazuki's route even has her called out on this after she allows someone to kill him because she deemed it to fit her morals. Though this is justified, as she was created from nothing specifically to serve this purpose.
  • Playing with Fire: One of the killer's powers is pyrokinesis. They were originally thought to be Senri but it was another person named Riko Haida impersonating her while using their power.
  • Punny Name: Some of the deaths are given this. Gottsuan Deathnote  and Revolving Dead are two of them.
  • Reality Ensues: Nono's route deals with this when Sakuma dies and doesn't have life insurance to support Aoba Dorm.
  • Recap Episode: The hour-long first episode of the anime spends its first half recapping the main events of Chaos;Head for viewers who didn't play the VN or watch the anime adaptation.
  • The Reveal: Serika and Sakuma were behind the murders and Serika was actually created into existence by Takuru himself to be his friend with his powers after the earthquake. She was carrying out the murders to fulfill Takuru's desire to recreate the New Gen murders and be in the same position as Takumi Nishijou who he thought was cool for revealing the true culprits of the original murders.
  • Story Branching: Happens upon fleeing from the attack on Takuru and Arimura from the pyrokinetic. Where Taku ends up and whether he's with Arimura or not is a result of the route he's on.
  • Story-Breaker Power: Deconstructed. Kazuki, Takuru's clubmate has the power of imagination, which would theoretically allow them to do whatever they want on a whim. But instead of their imagination, it's the power of the imagination of other people and is triggered when Kazuki says something and multiple people imagine the same thing, explaining why she's only speaks in grunts all the time. It ruined the life of the user's best friend and causes the entire plot to derail in one route, all inadvertently.
  • Superpower Lottery: Of varying levels, though it's not a "true" lottery because of how Gigalomaniacs came to be. Though most powers have drawbacks in spite of their awesomeness, one character in the story is the biggest loser, having only the ability to sense the emotions of a single person. There are also two winners: Wakui, who isn't limited to any specific power, and Takuru, who is not only stronger than Wakui, but is capable of doing even more if he had any real experience, due to both of them being True Gigalomaniacs.
  • This Loser Is You: Takuru. He gets better as it goes along.
  • Title Drop: The Chaos Child Syndrome, a condition that manifested for kids when they became Gigalomaniacs during the Shibuya earthquake.
    • It's also the name of the VN's True Ending.
  • Too Long; Didn't Dub: The fourth death is dubbed Gottsuan Death even in the English translation of the VN, due to how difficult it would be to make a proper translation. For those who don't know, gottsuan is a very polite sumo-specific way of saying "thank you" and doesn't have anything resembling an English version.
    • According to the title card, chapter 2 in the VN is called Rikishi Sticker, which would translate to Sumo Sticker. Weirdly, both the text log for the title card and the save screen do translate it as such, and “Sumo Sticker” is also used in the game otherwise. However, any CGs that show characters with “RIXY” shirts on also leave the text unaltered.
    • Kazuki’s route depends on placing pins on specific points on a large map of Shibuya according to the dialogue. Unfortunately, all of the map’s text is left untranslated, so any player who can’t read Japanese is left either resorting to a guide or just trying to guess the correct points based on the map’s features. (Fortunately this and all of the other issues are fixed with the Commitee of Zero patch)
  • Tulpa: Serika Onoe, Takuru's best friend, start as his Imaginary Friend and become an independent human due to his power and wish during the Shibuya Earthquake.
  • Wham Episode: Episode 07, "untitled".
  • Yaoi Fangirl: A positive delusion in chapter 3 has Arimura be one of these by having Miyashiro read a yaoi doujin she made.
