He didn't make a comment that "connected" it, don't twist it around. All he did is make a comment "acknowledging its existence" and the manga's connection to an anime storyline (hence the translation calling it an "anime version").

Problem with that argument is that said character is a prevalent character that fits into the current storyline, has significant impact from the anime, and is given backstory to further elaborate that we should know of the character already (from somewhere, it being the anime). Raiga was just thrown in for reasons, just like Kiba.
