Greetings after an eternity, I just realized the final chapter was never uploaded to this blog.
Please click here for the FULL Volume 1 to Volume 17 of IS [ai-esu] ~Otoko Demo Onna Demo Nai Sei~
...on our head translator Megchan's site.
Eternally grateful to Megchan for keeping the files neatly tidy and links active.
