Doesn't happen nearly enough in manga, or IRL either honestly. "Violence is bad!" Yes, but some people are just such huge assholes that they need a whallop. Violence is not the answer, it is the question. And sometimes- only sometimes- the answer is "yes".
While I appreciate backstory and worldbuilding I can't help but feel that how long this took is a little bit of the author going "shit, why did the clover stop working, I need to come up with a good reason. Uhm uh UH I cast Power Word: Flashback!"
It's almost like they wrote the plot of OC1 first and then did the bare minimum of alterations to try and make it fit, except they half-assed even that!
Kuuga's final fight slaps.
No Rider Kicks. No special attacks (pyrokinesis nonwithstanding). Just an unstoppable force and an immovable object beating the living hell out of each other until one stops getting up.
ORT is the final baddie of Lostbelt 7, to make a long story short.
A longer explanation, which will be put in spoiler tags because it is somewhat spoilery both for Fate and the Tsukihime setting:
tl;dr Do Not Approach The ORT.
If the manga is skipping the Sasha glazing then that means there is a chance, however microscopic, that maybe this time around Hyce won't be made to be the party bitch and she might actually face consequences for her actions. It is small, it's true, but it wouldn't be the first time a manga went...
I fail to see how that matters. "They're still just teens" does not preclude them from facing consequences for the act of being a dipshit. Everything else aside, the fact she didn't even try to apologize to him for two years would be enough to justify him not wanting anything to do with her...
So, in summary: the Author is Motomu Toriyama, Sasha is Lightning, and this slop is more of his weird-ass obsession over a fictional character. Will he strangle it with his bare hands, ala Third Birthday? I'm morbidly curious to find out.
Ah, most of my Rider knowledge is of the Heisei/Neo Heisei era, I'm less familiar with the Reiwa Riders. Zi-O falls into the same category of Kabuto where that's just time shenanigans, that's not an actual revive.
