Chaos;Child

Chaos;Child (カオスチャイルド, Kaosu Chairudo, stylized as ChäoS;Child) is a visual novel video game developed by 5pb. It is the fourth main entry in the Science Adventure series, and a sequel to 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.

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. The composer, Takeshi Abo, wrote down his impressions of the game's events and emotional flow prior to creating the music, to be able to create music with good relationship to the game's worldview. The game was well received by critics, but the Xbox One and PlayStation 3 releases failed to chart on Japanese weekly sales charts during their debut weeks. Other media based on the game has been produced, including an anime adaptation, a manga, an audio drama, and the spin-off game Chaos;Child Love Chu Chu!!.

Plot
Shibuya, Japan, 2008. Takumi Nishijou, a high school student at the Private Suimei Academy, one day hears about the 'New Gen' murders that have been occurring around the city. Although dismissing the subject because it doesn't involve him, Takumi begins to experience strange mishaps around him, from a horrific picture he received while on his PC, to a mysterious Pink-Haired girl standing at a murder scene.

From there on Takumi struggles to cope with the events unfolding around him, and is soon unaware of what is real or a delusion. As his fate opens up before him, the perpetrator behind the 'New Gen' events attempts to find him, leading him into a world where nothing is as it seems.
