About ChäoS;HEAd

Shibuya has been the epicenter of a series of bizarre crimes known as the New Generation Madness murders (or “New Gen” as it was shortened to on the web). So far, two cases have already rocked the media and inhabitants of Shibuya, and one day on his way home from school, Takumi Nishijou witnesses the bloody scene of the third crime.

Special Thanks

Without the help from everyone editing this poor isolated FANDOM wiki since its early days on Wikia when it was actually two separate wikis, and, neither of them would have lasted very long.

There would not have been two high-quality ChäoS;HEAd wikis to merge together into this even better unified ChäoS;HEAd Wiki that combines all information from both wikis. Thank you everyone for editing information into the characters, etc. on both original wikis as well as this merged one. We love you guys!

ChäoS;HEAd (カオスヘッド, Kaosu Heddo) is a Japanese visual novel developed by Mages (formerly known as 5pb. Inc.), Nitroplus and RED FLAGSHIP. Its enhanced version, ChäoS;HEAd NoAH, is the first entry in the Science Adventure Series, which spans several visual novels and other media entries. ChäoS;HEAd is set in Shibuya, Tokyo, and is about Takumi Nishijou, a withdrawn 17-year-old gamer and anime otaku with frequent delusions, whose daily life takes a sharp turn when he first witnesses one of the murders of a serial killing. Does everyone else around him have it in for him now, or is it just paranoia? Could it all just be another delusion? What is real and what is fake?

... Whose eyes are those eyes?
