If you look at the bottom right corner of the manga, in this picture, you can see that it says “海外の2ちゃん的な掲示板で大人気!!”. Which translates to “On a foreign 2chan-like board, this manga has become extremely popular!!” And the ‘foreign 2chan-like board’ in question is indeed our home 4chan.
When I originally typeset chapter 2 on a whim, on /a/, all those months ago I never thought something like this would happen. And you know what? That’s pretty damn cool. Of course this definitely would not be possible without all you guys out there reading it, and subsequently buying it, regardless of if you’re from /a/ or not, be proud of yourselves.
