Welcome to the N-H-K

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.

In the park late at night, Tatsuhiro meets Misaki who claims to be able to cure him of his hikikomori ways, as long as he signs up to her project. Tatsuhiro remains stubborn and decides to forget about it however Misaki doesn’t give up that easily. So in the spur-of-the-moment Tatsuhiro lies by telling her that he has a job as a “creator” but she doesn’t believe him and asks for proof.

By chance Tatsuhiro discovered that his noisy otaku neighbour was in fact an underclassman he knew from High School and they end up deciding to create an eroge (erotic game). Before this Tatsuhiro must first get some inspiration by trying out some eroge himself nonetheless he gets absorbed into the sordid world of bishoujo “beautiful girls”.

The eroge creating has begun however Tatsuhiro has writer’s block, as he is unable to come up with a scenario or a main heroine for it their eroge. So Kaoru drags him out to many otaku hotspots, like maid cafe, to help him come up with a heroine but this appears to be a new world to him.

After 4 years and 4 months, Tatsuhiro has run into his old senpai from High School, Hitomi who now has become a civil servant. His reunion with Hitomi may have sparked something inside him, because now he feels the need to stop running away and to face his problems as a hikikomori. Now the counseling can begin.

Tatsuhiro is struggling with the scenario for his eroge but this has to wait as he has his 2nd counselling session with Misaki. During this session the subject of Kaoru’s girlfriend comes up, which comes as a shock for Tatsuhiro who never thought of him as the girlfriend type. To confirm this Tatsuhiro follows Kaoru to his design school, where he happens to get lost and ends up in a class for game writers.
