I still don't know what "Over-Quartzer" means but while "Journey Through the Decade" was this very dramatic and almost melancholic ballad like Opening, Zi-O's is more jazzy, fun, and twisty which I think works pretty well.

Sougo's a nice kid who wants to be king. That's...pretty much it!

Toei wasted no time using their classic Edo sets. It's almost as much a staple as the Kamen Rider Quarry.

Where as Decade's design was kind of garish but in a way taht surprisingly worked and stood out, Zi-O's design is clinical, basic, yet it's functional nature serves to make the design still "pop" in my opinion.

I like everything about Tsukuyomi's whole look. That long dark hair, the white dress and black leggings, the boots, etc. It's a very eye-catching look that honestly wouldn't look out of place in an anime. Also from the get-go you have an interesting character conflict where we start out seeing her father (?) seemingly murdered by Ohma Zi-O but she still goes out of her way to save his younger self and give him a chance even when it seems like she's wasting her time. Which contrasts with Geiz who just wants to go full "time travel murder."

If I had a nickel for every time a 2nd Rider was introduced trying to kill the Main Rider...I mean, honestly I'd have a lot of nickels. I did find it kind of interesting that Zi-O didn't just get all the Main Riders, it was initially split between Geiz having some and Zi-O having some as well (although of course Zi-O got the most). I kind of wonder if making Geiz' gimmick being just 2nd Rider based could have worked.

Just like with Decade, the prior Rider has a role to play in the premier of an anniversary show, although it's actually Sento and not just some weird cosmic version of Wataru. Granted there's also some wibbly wobbly timey-wimey elements at play that kind of make Sento and Banjo's involvement a little...interesting, but it's still nice to see them.

I always thought the Another Riders were kind of a genius convention for this show because it kind of sums up the Heisei era of Kamen Rider and the entire concept of Kamen Rider by basically taking the Riders and turning them into Kaijin, fulfilling the need for Kamen Riders to fight Kaijin while also echoing the Rider vs Rider element that became a thing with the Heisei era. And, y'know, Riders are more often than not interconnected with their Kaijin so to just straight up make them Kaijin is perfect. They also come about it in creative ways where Another Build retains Build's Fullbottle gimmick but in a way that makes sense for the user rather than just a copy and paste. And if I remember right, did they not get the monster designer from the respective Rider shows to do the Another Rider designs?
