Chaos;Child[a] is a visual novel video game developed by
5pb. It is
the fourth main entry in the
Science Adventure series, and a thematic
Chaos;Head (2008). It was released in
Japan in 2014 for Xbox
One, in 2015 for PlayStation 3,
PlayStation 4 and PlayStation Vita, in
2016 for Microsoft Windows, and in 2017 for iOS and Android. The
PlayStation 4 and
PlayStation Vita versions were released by PQube in
North America in October 2017.
The player takes the role of Takuru Miyashiro, the president of his
school's newspaper club, who experiences delusions. At multiple points
throughout the story, the player gets the option to choose if Takuru
should experience a positive or negative delusion, or neither: these
choices affect the plot's direction, causing it to branch off from the
main narrative into different routes.
The game was created to have "psycho-suspense" elements similar to
Chaos;Head, while also adding a larger amount of horror elements. For
the game's aesthetic, the developers aimed for it to be "unmoving", in
contrast to the previous
Science Adventure game, Robotics;Notes
(2012). The music was composed by
Takeshi Abo based on notes of his
impressions of the story and emotional flow, to ensure a good
relationship to the game's worldview. The localization was handled by
Adam Lensenmayer, whose experience with translating the Science
Steins;Gate 0 (2015) ensured a smoother localization
process, with a lot of communication with the developers. Chaos;Child
was well received by critics, but the
Xbox One and PlayStation 3
releases failed to chart on the Japanese sales charts. Other media
based on the game has been produced, including an anime adaptation,
two manga series, an audio drama, and the spin-off game Chaos;Child
Love Chu Chu!! (2017).

The player changes the direction of the plot by choosing to experience
positive or negative delusions, or neither.
Chaos;Child is a visual novel, which is split into multiple different
story routes. During a first playthrough of the game, the player can
only play the main narrative; after finishing the game once, other
routes that branch off of the main narrative at different points
become available. Each route focuses on one of the game's characters,
dealing with character motivations and secrets not revealed in the
At multiple points, the player gets the option to choose whether the
player character should experience a positive delusion or a negative
one; they can also choose neither and stay rooted in reality. These
choices change the player character's world view, as well as who he
trusts, and are what causes the story to branch into different
Setting and characters
Chaos;Child is set in
Shibuya in 2015, six years after the events of
Chaos;Head, where an earthquake nearly leveled the area. It
follows a group of high school students who survived the
earthquake; among them is the player character Takuru
Miyashiro, who is a senior in high school and president of the
school's newspaper club, and whose family died in the earthquake.
He is accompanied by his childhood friend Serika Onoe and his
foster sister Nono Kurusu, who are the game's main heroines and
romantic leads. Among other characters are the newspaper club members
Hana and Itou; 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. Several of the characters have superhuman
abilities: for instance, one can spot lies with absolute certainty,
while another can use pyrokinesis.
Six years after the events of Chaos;Head, the city of
Shibuya has been
rebuilt and the survivors have continued with their lives. However, a
new series of odd killings begin to occur on the same days of the New
Generation murders, and are done in similarly odd ways, leading people
to begin calling them the New New Generation murders. Takuru takes a
personal interest in the murders and begins investigating them with
the help of his fellow club members, much to Nono's dismay. Mio and
Shinjou are also investigating the murders on the behalf of the police
and Mio's own motives. Eventually, Takuru follows a set of clues to a
love hotel where he encounters Hinae, a fellow student at his school
at the scene of another killing. Hinae afterwards reluctantly agrees
to assist Takuru and Mio in their investigations.
After more killings, Takuru learns that they are all connected by the
presence of Sumo Stickers at the crime scenes, and he receives a tip
to investigate the basement of AH Tokyo General Hospital where the
creator of the Sumo Stickers is allegedly being kept. Takuru, Serika,
and Itou sneak into the hospital, where both Takuru and Serika have
flashbacks of a girl being experimented on. They then meet Mio, who
reveals that there is a secret facility under the hospital created by
the Committee to study Gigalomaniacs, individuals possessing the power
to create delusions. She breaks into the facility's computer network
and reveals the Committee created the Sumo Stickers and were
responsible for experimenting on Senri, the girl Takuru and Serika had
seen in the past. Mio then kidnaps another test subject, Uki, and the
group makes their escape. Afterwards, Mio further explains to Takuru
that he most likely is a Gigalomaniac himself, and Hinae manifests her
Di-Sword and demonstrates her ability to detect lies to prove it to
him. Takuru also surmises that all of the victims in the New New
Generation murders are also Gigalomaniacs.
Later, Takuru and Hinae are attacked by a pyrokinetic Gigalomaniac
whom they suspect to be the killer. Nono also reveals to them that she
was childhood friends with Senri and was aware of the experiments that
were being performed on her, and decides to help in their
investigation as well. Working together, Takuru and his friends manage
to avoid becoming victims in the subsequent New New Generation
murders, until the pyrokinetic herself is found dead. Everybody lets
their guard down, believing the murders to be over until Itou murders
Takuru and Nono's adopted younger sister, Yui. Itou claims it is
revenge for leaving Senri to die, but Nono concludes that Itou is
being mind controlled. Itou the collapses from the strain of the mind
Some time after Yui's murder, Takuru follows Nono to the roof of the
school, where he finds Nono and Serika battling each other with
Di-Swords. Takuru attempts to intervene, but Nono is killed by Serika,
who leaves the scene. Takuru is implicated in Nono's death and becomes
the prime suspect for the New New Generation murders, so he decides to
hide out with Mio. Serika then arrives and reveals that she is in fact
a delusion created by Takuru during the earthquake when his powers
manifested, her sole purpose being to protect him. She also reveals
that Takuru and Nono's adoptive father, Sakuma, is in fact responsible
for the New New Generation murders and is a Committee member seeking
to exterminate the remaining Gigalomaniacs. She pleads for Takuru and
his friends to flee
Shibuya before leaving. Hinae warns Takuru that
Serika was not being entirely truthful about her desire to protect
him, so he decides to confront her again to find out for sure.
Takuru heads for the Theater Cube to confront Serika again, but
instead met by Sakuma, who has his own Di-Sword and a backpack capable
of generating delusions. He traps Takuru in several delusions in an
attempt to destroy his sanity, but Takuru is able to hold on to his
sense of self and uses his own Di-Sword to kill Sakuma. He then
battles Serika and views her memories, finding out that Serika was
created to carry out his innate desire to be a hero like Takumi, who
solved the New Generation murders. In order to achieve this desire,
Serika manipulated Sakuma into arranging the New New Generation
murders for Takuru to solve. Realizing everything is his fault and not
wanting to play Serika's game any longer, Takuru uses his powers to
turn Serika into a normal girl.
In the aftermath, Takuru's surviving friends go about their daily
lives. Takuru himself is taken into police custody and Serika has gone
missing. Takuru is reported to have died while in police custody,
while Serika asks him if he was able to do what he wanted to do.
This route triggers if Takuru was able to intervene in Nono and
Serika's duel and saves Nono's life. Upset that Takuru saved Nono,
Serika leaves. Takuru asks Nono what her power is and she replies her
power is similar to Hinae's lie detection. Sakuma ends up becoming the
next New New Generation murder victim. Takuru, Nono, and their friends
attempt to continue a normal life afterwards, until Serika appears
again and reveals that Nono is in fact Senri. The real Nono died in
Shibuya earthquake, and Senri so desperately wanted to be like
Nono that she gained the power of transformation, taking on Nono's
appearance and identity. Takuru becomes angry at Senri for lying to
him and forces her away. However, he comes to regret his outburst
after realizing that despite taking on Nono's appearance, Senri's love
for him was still real. Takuru subsequently loses the will to live and
Serika arrives to kill him and fulfill his desire. Senri intervenes
and Takuru's desire changes to being with Senri. Seeing that she no
longer has any purpose, Serika kills herself. Afterwards, Senri takes
on her original identity and lives happily together with Takuru as
they go visit the real Nono's grave.
This route triggers if Takuru decides to flee to the school to evade
Haida. There, he runs into Hana, who uses her powers to summon a
portal device from her favorite game "Ensue 2", which defeats Haida.
Takuru takes shelter with Hana at her home, where she explains that
she has the ability to make the words she speaks reality. However, she
doesn't have full control over ability, so she voluntarily stays mute
to keep herself from accidentally harming others. They soon learn
about numerous other portal devices appearing around
Shibuya that are
creating monsters from Ensue 2. One of Hana's gaming friends warns
them about the Committee, and that one of their teachers, Wakui, is a
member. Wakui captures Nono and holds her hostage to force Hana and
Takuru to meet him, intending to capture Hana for his own ends. Hana
is able to summon a giant and commands it to attack Wakui, killing
This route triggers if Takuru gets separated from Hinae when they are
attacked by Haida. They manage to reunite and hide in Takuru's home.
Haida is arrested shortly after, and Takuru and Hinae continue life as
normal. Through a combination of flashbacks and information from Nono,
it is revealed that Hinae's brother died in the
and his dying words admitted that she was adopted. Wanting to find out
the truth, Hinae gained the power to detect lies. In the present, more
mysterious murders begin to occur and someone attempts to push Hinae
in front of a moving car. Takuru discovers the corpse of Hinae's
father and Hinae begins to suspect her brother is the killer. Takuru
begins to investigate and discovers that the murderer is in fact
Hinae's mother. When Hinae attempts to confront her mother, she can
tell everything she is saying is a lie. She attempts to stab Hinae,
but Takuru uses himself as a shield and is stabbed instead. Hinae's
mother escapes leaving Hinae to tend to Takuru. Takuru dies from his
wounds, but Hinae creates a delusion for herself where she is living
happily with him.
This route triggers if Uki arrives at Yui's murder scene, where she
tries to attack Itou with her Di-Sword. Takuru attempts to stop her
and is hit instead, falling unconscious. When he wakes up, he finds
out that the murders have stopped and Yui is somehow still alive.
Everything seems to be going well for him, such as becoming a
commentator on a popular internet show and being asked out by Yume,
the most popular girl in the school. However, he keeps receiving
constant delusions of Serika and Nono trying to contact him, and Uki
appearing with her Di-Sword. Serika and Nono warn him that he is
trapped in a delusion created by Uki, and his real body will die if he
doesn't escape. Uki then arrives and pleads with him to stay in the
delusion, where he can be happy. A second Uki then arrives and defeats
the first one, explaining that she is in fact the real Uki and the
other is a delusional version of her. She urges Takuru to escape as
the delusional world collapses, and he wakes up in the real world.
However, Uki remains comatose as her own mind is still trapped in the
delusion. Takuru resolves to take care of her.
Chaos Child/Silent Sky Route (True Ending)
In a continuation of the main route which is only unlocked after all
alternate routes are completed, Serika wakes up in her bed after
having a strange dream, and has no memories of Takuru or any of the
game's previous events. She goes to
Shibuya to meet some friends and
experiences a strong sense of deja vu when she sees her old school.
There, she meets Mio, who tells her that all the students at the
school are suffering from Chaos Child Syndrome, a condition that
manifested when they became Gigalomaniacs during the Shibuya
earthquake. However, all of the people afflicted with Chaos Child
Syndrome have trapped themselves in a collective delusion separating
them from the real world, and Mio seeks to find a way to cure it. Mio
then introduces Serika to Takuru, who was the only Chaos Child who
managed to break free from the delusion. They head back to the school
to infiltrate a secret lab hidden there. Takuru uses the lab equipment
to scan his own brain, creating a cure for Chaos Child Syndrome. They
are then confronted by Wakui. He allows Takuru to spread the cure,
since he is interested in the potential data and achieves his goal to
eliminate the Gigalomaniacs. Afterwards, Serika parts ways with Mio
and Takuru and goes to see a play, where she apparently begins to
remember her previous life as Takuru's friend.
In the final epilogue, Senri, Hinae, Hana, and Uki are shown to have
been cured of their Chaos Child Syndrome and are living happy lives.
Takuru is taken away by the police to be put in isolation due to his
role in the New New Generation murders. While being escorted out of
the hospital, he unexpectedly comes across Serika again. When Serika
is asked by her friend if she knows Takuru, Serika claims that she
does not. Takuru silently agrees that he no longer knows Serika
The game was developed by 5pb., based on an original plan by
Chiyomaru Shikura, the head of the company. It was produced by
Tatsuya Matsubara and directed by Kanji Wakabayashi, and was written
by Eiji Umehara, Masashi Takimoto and Tōru Yasumoto under supervision
by Naotaka Hayashi. Several artists worked on the game: Mutsumi Sasaki
designed the main characters, Yukihiro Matsuo designed minor
characters and uniforms, and Choco designed the characters' Di-Swords.
The game made use of "psycho-suspense" elements similar to those in
Chaos;Head, but with an increased amount of horror elements. For the
game's look, the developers were aiming for an "unmoving aesthetic" as
opposed to the "moving adventure" style of the previous Science
Adventure game, Robotics;Notes. To create subtle differences in the
game's atmosphere, four different graphics shaders were
implemented. For the
Xbox One version of the game, the developers
made use of the console's controller to play the in-game phone calls;
this and some other features had to be changed when the game was
ported to other platforms.
The music was composed by Takeshi Abo, who used the same technique as
for his previous works in the
Science Adventure series: he started by
reading the game's story, to understand the setting and characters as
fully as possible, and wrote down his first impressions of the events
in the plot, as well as of the plot's emotional flow. He considered
these first impressions to be very important, and used them to create
a musical worldview. According to Abo, this method takes longer than
just designating songs to various areas in the game, but allows him to
create higher quality music with a better relationship to the game's
worldview. The "image" used for the composition was different than for
previous games in the series: while he described
Chaos;Head as rainy,
Steins;Gate as cloudy, and
Robotics;Notes as clear weather, he called
Chaos;Child "stormy", and contrasted its "black-and-white" image with
Robotics;Notes's "colorful and emotional hues". Because he found the
game's story compelling, he enjoyed composing the music and wanted to
create even more for it by the end of the project.
Chaos;Child was localized by Adam Lensenmayer, who previously worked
on the localizations of
Steins;Gate 0 and of the anime adaptation of
Steins;Gate. He was the only translator working on the localization;
this was done as he and the developers wanted to ensure consistency in
the way each character speaks and in the feeling of the game, as
having multiple translators work on a single project can lead to
differing interpretations of the story and of characters'
personalities. He had not played the game prior to the start of
localization, so after finishing his first translation pass of the
script, he went through it in full a second time to correct things he
had originally misunderstood due to not knowing how the story plays
While Lensenmayer described the translation itself as straightforward,
due to the Japanese dialogue being easily understandable, he found the
game exhausting to work on, giving quality control of the game's
opening sequence as an example: he had to keep watching the opening to
check text that is only displayed briefly on-screen, and thus had to
see a character choking to death many times. The localization was
additionally a large project with a script 30–40% larger than
Steins;Gate 0's, taking most of the remainder of 2016 to finish
following the completion of the
Steins;Gate 0 localization. Due to the
experience of having worked together with the developers on the
Steins;Gate 0, the process was however smoother, with
a lot of communication back and forth on how to localize various
things. The localization took fan feedback into account: after
Lensenmayer had submitted the localized script, he worked on the
translation of the
Chaos;Child anime adaptation, and read comments
about how some translation choices in the anime were inconsistent with
their use in Chaos;Head, such as the rendering of a phrase as "Those
eyes! Whose eyes?" rather than "Whose eyes are those eyes?!".
Contacting the developers, he was able to get most such instances
changed in the game script.
Chaos;Child was originally planned to be released on November 27, 2014
Japan for the Xbox One, but was delayed, and was released on
December 18, 2014. It was later ported to the PlayStation 3,
PlayStation 4 and PlayStation Vita, and released on June 25, 2015;
Microsoft Windows version was released on April 28,
2016, an iOS version on January 31, 2017, and an Android
version on May 28, 2017. The
PlayStation 4 and PlayStation Vita
versions were published by PQube in
Europe on October 13, 2017, and
North America on October 17, with a physical North
American release following on October 24.
A limited edition of the Japanese PlayStation 3,
PlayStation 4 and
PlayStation Vita versions was made available, which includes a drama
CD and a "present box" paper craft. The Western release was also
made available in a "Gigalomaniac Edition", which includes an artbook,
a soundtrack and a set of pin badges.
A manga adaption drawn by Relucy is published by Kadokawa in Dengeki
G's Magazine; there is also a spin-off manga, Chaos;Child:
Children's Collapse, which is drawn by Futsū Onshin and written by
Chaos;Child game's writer Eiji Umehara. It was published in
Monthly Shōnen Sirius
Monthly Shōnen Sirius starting in August 2016,
and moved to
Kodansha and Niconico's web magazine Suiyōbi no Sirius
on September 27, 2017. An anime television adaptation of the game
was produced by Silver Link, and began airing in January 2017.
A spin-off game,
Chaos;Child Love Chu Chu!!, was released in 2017;
to coincide with this and the anime,
Chaos;Child receiveved a
budget-priced re-release on March 2, 2017. Additionally, Shikura
has said that he wants to make an erotic game based on
Chaos;Head, targeted at adults.
Chaos;Child was generally well received by critics, according to the
review aggregator Metacritic. Richard Eisenbeis at
the game excellent, and a good addition to the series. He enjoyed the
story, calling the mystery "thrilling", and saying that the
"disturbing and intriguing" murders were one of the best aspects of
it. He also enjoyed the game's characters, calling them deep and
layered, and said that watching them try to outwit others' powers and
using their own to the fullest was another highlight. He liked how the
developers had gone "all in" when making the branch routes; the thing
he liked the most about them was the consistency of the characters and
their motivations between different routes. He found the game to be
very long, however, taking him over 70 hours to play through, which he
said could be a potential flaw.
Xbox One and
PlayStation 3 versions of the game were unable to
reach the Japanese weekly sales charts upon launch; the
PlayStation Vita and
PlayStation 4 versions did, however, selling
10,325 and 4,860 copies, respectively, with the PlayStation Vita
version being the ninth best selling game of the week. On the
following week, the
PlayStation 4 version had dropped off the chart,
PlayStation Vita version dropped to seventeenth place with
2,556 additional copies sold. In the United Kingdom, Chaos;Child
was the best selling
PlayStation Vita game during its European debut
week, and still charted in March 2018;[b] the PlayStation 4
version did however not appear at all in the platform-specific, weekly
top-twenty game sales chart for the region.
