With the way the Kurotsubaki appeared in the manga can we assume the anime version of the it was uncanon?
Well, maybe it's like the first anime's Shion and Kuzuha, they appeared in the manga but we know they won't do anything. Maybe the Kurotsubaki backstory is just like in the anime, but the whole Vegas trip just won't happen... but then, why did Hata teased Ruka's Vegas concert anyway?
This is confusing, I know plot holes in Hayate are plenty, but saying both are canon is ridiculous. He took weeks off to draw storyboards for CTMYOY, but he can't just plan the whole thing straight?
