A Mitsudomoe doujin to serve as a speculative epilogue to the series by the pixiv user Quick Waipa (http://www.pixiv.net/member.php?id=321750). First of two parts.

Incredible enough, to latest published ch.315 (02-2016), this hypothetic end story still remains valid enough to be considered an alternative candidate to become ending canon... If main story wasn't comic/gag type. The story is pretty good, and it gets better in the remain parts.
Many thanks for translating it full guys, even the "bonus" page :-P. Waiting patiently for the next part.
