Welcome to the N.H.K. 1x17

The call Tatsuhiro received was from the class representative from High School, Megumi who he ends up meeting with. He admits to her that he is a hikikomori, so she invites him to her successful senpai who can supposedly cure him of his NEET problems. However once arriving to a weird seminar Tatsuhiro has noticed that he has wondered into a Pyramid Scheme.
