I wouldn't really like that, anyway. I think for one season it could potentially be a cool idea, to have the main Rider having to take down last season's; but after the second year you'd be kinda sick of it, never mind 10. One of the great things about Rider to begin with is how most seasons are standalone stories that are all allowed to do their own thing and be wildly different from the last, and having the objective of each be having to deal with some edgy Evol Black Hole wannabe would quickly diminish that. Aruto's angst over his dead secretary is not capable of carrying a story for long.

Besides... honestly, I'm a bit sick of Zero-One and wanna quickly move on. This past stretch of episodes has been dire and I'm ready for something new.
