Welcome to the NHK

Satou Tatsuhiro is a 22-year-old college drop out. As someone who is Not in Employment, Education, or Training (NEET) and a hikikomori (one who is socially withdrawn), he stays in his apartment and has to constantly listen to the PuruPuru Purin anime song of his next door neighbor, thinking the world is conspiring against him and driving him into this hikikomori state. One day he meets Misaki Nakahara who invites him to her project to cure him of his hikikomori ways.

I've only watched three episodes of this anime, it's cute with its talking refrigerators and weird monsters. A comedy that any otaku can enjoy, but certainly not a masterpiece.
