What the hell; I have nothing better to do, so I feel like handing out a nice doujin for /a/ tonight.
(Warning: In case the cover doesn't make it obvious, this doujin contains spoilers for Haibane Renmei, Serial Experiements Lain, and NieA_7. The humor probably won't make sense unless you've seen all three anyway.)
Special bonus of the author being a cocktease.
And that's it.
