If you've heard of/are watching/played Steins;Gate, you know what to expect, pretty much; the arbitrary semicolon in the name indicates that it is part of the same game series (made by visual novel company Nitro+.) Instead of Akihabara, though, this takes place in Shibuya, and follows an antisocial shut-in named Takumi Nishijou, who suffers from many problems--the most pressing of which is the frequent delusions he has (to show the severity of this, his 2-D waifu Seira-tan materializes in front of him regularly and declares her love for him) . These delusions eventually grow to incredible proportions, effectively erasing the line between his imagination and his reality and making him incredibly paranoid. On top of all that, a series of murders, called the "New-Gen" incidents, have been taking place, torture devices shaped like crosses show up in his room, the message boards he frequents show him disturbing images, and every girl he runs into seems to either want to kiss him or kill him. All of these things seem to be connected to him somehow, and the fun of ChaoS;HEAd is figuring out exactly how.
Many people have mixed feelings about this anime for many different reasons, but I thought it did a lot of things really well, and I'm quite eager to play the VN someday due to it. Also, you're always super special. Never forget that.
If you've ever seen Paranoia Agent and you're thinking this sounds similar, get that shit out of your head right now, this is nothing like it. Recommended for fans of Higurashi, Umineko, Fate/stay night, or any other anime adaptations of story-based visual novels.
