Welcome to the N-H-K – Folge 1

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.
