Come on people, it's pretty obvious that this wasn't axed, it wasn't even officially published after all. As of now, it's just a webcomic that the author posts on Twitter and comic-meteor(and the 4 extras on Pixiv), for free. There's 2 possibilities that could've created these rumors:
[ol]Author got bored of it and decided to end the series, which is unlikely considering that he gets quite a lot of likes and RTs on Twitter (also, he would've said something by now).[/ol]
[ol]It was going to be picked up by a publisher, but they gave up for some reason.[/ol]
