NHK ni Youkoso
Satou Tatsuhiro is a 22 year old man, who is a NEET (Not in Employment, Education, or Training) and a hikikomori (meaning acute social withdrawal). He thinks everything around him is a conspiracy, including the reason why many people, including himself, become hikikomori. Satou comes up with this strange conspiracy theory which includes the Nihon Hikikomori Kyōkai (NHK), a secret organization with the intention to make the world filled with hikikomori. Satou wants to break free from the NHK's clutches, but cannot, since he finds it too frightening to go outdoors by himself; that is until he meets Misaki Nakahara, who selects Satou for this "project" to cure him of his hikikomori ways.
