Tatsuhiro Sato is woken up from his deluded dream of conspiracies, by his noisy neighbour playing loud anime music non-stop. All this could be put to an end if he'd just go next door to complain however Tatsuhiro is unable to do this because he is a “hikikomori”. He later meets a girl named Misaki, who will later change his life around.

Tatsuhiro has managed to catch-up to Misaki, at the same cliff her mother committed suicide, in an attempt to stop the same incident from happening again. Having stopped her from doing such a foolish thing, the only way he can think of preventing it from happening again, is to do something as foolish. Now caught up in his fantasies about the conspiracies of the NHK, he tries to defeat it using unorthodox methods.
