Full color comic 60 pages

21 years old, high school dropout Hikiya Komori spent the last 5 years as a hikikomori (shut in).
He stopped existing to the outside world so much that his non-existence became a real thing.

"Where's my brother?" his annoying sisters asked while staring right through him.
"I'm here... don't you see me?"

He took off their clothes, had sex with them, even creampied inside them... they just rolled with it.

Hiyiya went outside for the first time in five years... with a plan to cause some mischief...
