Err... all you can come up with?! Most of this is just based on Missing Ace o_O

Anyway, Blade already gets a canon sequel and that's the Drama CD.

If we're counting supplemental materiel we also got those light novels.

It's don't think those are considered canon though.
And I would really be afraid to consider this canon because novels written by Toshiki Inoue are really... terrifying in one way or another. And he happened to write the Blade novel.

Blade novel is written by Miyashita Jyunichi, who has written 4 episodes of Blade.
The novel makes little sense to many, but the second part of the story makes it perfect for a 3 hours sci-fi movie.

Were the novels translated?? Officialy or by fans??

Then my source was wrong. Thanks for clarifying. :D
