Re: 1 & Only License Rumors & Speculations Thread
To add fuel to the JoJo rumor: the Mayo Chiki manga mentioned it by name. Based on how Hayate handles references to other manga, I expected it to be censored in SOME fashion. But no, it wasn't censored at all, not a single letter. And the back cover makes mention of Sentai having the Mayo Chiki anime, so I'm thinking there may be some link there.
That, or it's completely unlicensed and thus 100% free range.
