Chaos;Head (カオスヘッド Kaosu Heddo?) is a Japanese visual novel developed by 5pb. and Nitroplus with gore, psychology, and science fiction elements that was released on April 25, 2008 for the PC.[1] The game is described by the development team as a "Delusional Science NVL" (妄想科学NVL Mōsō Kagaku NVL?).[1][2] The game's premise revolves around a high school student named Takumi Nishijō who unknowingly walks into the scene of a gruesome murder on his way home. More mysterious events starts happening afterwards as more gruesome murders occurs in the area. Takumi struggles to cope with reality and the delusions he experiences as he tries to avoid being getting caught by the perpetrator behind the chain of murders.

The game's story has been adapted into a manga that started serialization on May 21, 2008 in ASCII Media Works' shōnen manga magazine Dengeki Daioh.[3]

The gameplay of Chaos;Head, like other visual novels, requires little player interaction as the game is primarily made up of text dialogues. The player only needs to read and click through the text to advance through the game. The text that is displayed on the screen depicts conversations between different characters or their thoughts.

Chaos;Head presents choices to the player through a unique "delusional trigger" (妄想トリガー mōsō torigā?) system.[4] This system presents the player with three choices relating to Takumi's psychological state. Two cardiac cycles will be displayed on the screen. A green, stable one will be on the top left hand corner and a red, unstable one will be on the top right hand corner. The third choice is not visible to the player as it requires no player interaction. The player may choose to click on the green or red cardiac cycle, or to simply proceed through the game without selecting either of them. The player is not required to make a choice immediately as the two cardiac cycles will remain on the screen until a predetermined number of lines has been passed since they appeared.

Selecting the cardiac cycles will often decide what kind of delusions Takumi will experience. The stable choice often shows a happy or humorous scene whereas the unstable choice will show very negative scenes possibly with gore and violence added. Yes and no questions also show up at times although they are much less frequent than the delusional triggers.

[edit] Plot

[edit] Setting and themes

Chaos;Head primarily takes place in Shibuya, Tokyo. Many of Shibuya's physical locales like its busy pedestrian scramble[5] and the Loft building appear in the game although their names have been altered slightly.[6] Some notable Internet websites like 2channel, YouTube, and Yahoo! also show up in the game with modified names as @-channel, MewTube, and Taboo!.

As the title implies, psychological themes relating to one's psyche and mind plays a large role in Chaos;Head. Delusions and the method of projecting one's own delusions onto the physical world, or onto someone else's visual system, is a key driver behind the story. Other scientific themes such as the concepts of matter, antimatter, and the Dirac sea are also brought up.

[edit] Story

Chaos;Head's story is set in the year of 2008 in Shibuya and is centered around Takumi Nishijō, a high school student at the private Suimei Academy, and some strange events that have occurred recently in the Shibuya area. Two events have occurred so far and is being referenced by the media and the public at large as being New Generation (ニュージェネレーション?) events. The first event named "Group Dive" (集団ダイブ?) occurred on September 7th with five high school students jumping to their deaths off of a high tower. The second event named "Pregnant Man" (妊娠男 Ninshin Otoko?) happened on September 19th wherein a male university student was found dead with a thirty-two week old fetus incised within his abdomen.

The story begins on September 28 with Takumi talking to an online friend named Grim (グリム Gurimu?). Grim is trying to bring Takumi up to speed about the recent New Generation events since Takumi is not interested local or international news. A person named Shōgun (将軍?) joins the chat room midway through Grim and Takumi's conversation but he does not respond despite being greeted by both Grim and Takumi. Grim sends Takumi a poorly drawn image of a person getting stabbed with several stakes. Grim claims that it is an image of the victim before leaving.

After Grim leaves the chat room, Shōgun finally starts to talk. He sends Takumi a barrage of several image links depicting a murder like Grim's image except that these images appeared to be real images. The next day, as Takumi was heading home after spending the afternoon at an Internet cafe, he comes across the same scene that he witnessed yesterday in Shōgun's pictures. He sees a male body nailed to the wall as well as a pink-haired girl dressed in Suimei Academy's uniform covered in blood. Takumi runs away screaming as soon as he comes to his senses over the situation at hand. The story progresses from here with Takumi trying to avoid getting involved with Shōgun and other New Generation events as he is slowly caught in a grander scheme's wheels of motion.
