Okay, Madoka Magica, you know how in the end the universe ends and gets reset with only Homura remembering what went on in the other timeline? That's pretty much the logic I use. All the riders worlds were destroyed then reborn, plus it's all AU an- I'm the only one here who gives a damn about Decade aren't I? :lol

I care about Decade.
It's just that the events of his series didn't happen.
While you could argue that Tsukasa remembers the events, the counter argument is that he's still amnesiac about what he was supposed to remember, so he's still an unreliable narrator since he doesn't even know what the fuck anymore.

:lolol

Decade is not very likeable. He is kind of a jerk for 31 episodes, and willingly go back to full evil in the 1st movie.
He's been finally heroic at the very end, sacrificing himself in the 2nd movie by letting Natsumi kill him to restore the balance of the multiverse. That doesn't justify him being a dick almost the whole time.

That works for me. I care about Decade too, I think the character is awesome and the series was interesting.

Stop right there, thank you for making me realize I'd despise Decade by comparing it to that festering lump of wasted beautiful animation and cute blue girl. :lol
