Welcome to the Dark Side!
The day after the fireworks festival, Tatsuhiro and Kaoru are back to working on their eroge nonetheless Tatsuhiro’s love for Misaki has grown and it’s beginning to surface itself in different ways. One thing that hasn’t changed is the fact that he still doesn’t know a thing about Misaki and he begins to have paranoid thoughts that she is plotting against him, as a part of the N.H.K.
Aired 11/09/2006EP 10 - Welcome to the Dark Side!

Welcome to the N-H-K
Satou’s life – or what’s left of it – is a paranoid mess of conspiracy theories and social anxieties. He’s terrified of the outside world; his apartment is overflowing with the remnants of cheap take-out food; and his retinas have been permanently scarred by a steady diet of internet porn. But maybe it’s not all his fault. After all, the nefarious N-H-K is out there, and they’re determined to turn society’s fringe-dwellers into a brainwashed lot of jobless, hopeless, futureless recluses.
Enter Misaki – a mysterious girl-next-door type who is Satou’s last chance to beat down his inner demons and venture out into the light of day. She’s ready to help him overcome his crippling phobias, but Satou would rather cower in his existential foxhole and pretend to work on the demo for his virtual sex game.
He’s afraid to face the world. She’s strangely desperate to fix a total stranger. Maybe together they can be normal.
