What's interesting here is that technically speaking, Ryuki shouldn't exist in the "main" timeline. He exists in an alternate past where Shiro Kanzaki started the Rider War.


With the Timejackers turning Shinji into Another Ryuga, this puts him in a very similar situation to Shinobi and Quiz, with the only difference being he's a Rider from the alternate future of the past (if that statement makes any sense whatsoever).

I can't tell if that's intentional or not, but it's interesting to think about.
