History Heartwarming / KamenRiderZiO

* It is ''very'' subtle but despite Tsukasa's [[Jerkass]] behaviour towards Sougo, Tsukaaa comparing Sougo's current situation at the alternate 2019 with his own shown that they are really NotSoDifferent with their inability to exist in a world that never acknowledged their existence.

** Because multiple alumni from past Riders appearing in this show, Satoshi Matsuda, actor of Ren Akiyama/Kamen Rider Knight expressed his wish to reprise his role as Ren and even guest starring in Zi-O. While the ''Ryuki'' tribute arc only features Shinji, his mirror duplicate and Daisuke Okubo, Matsuda gets his wish when the Rider Time Ryuki, a spinoff of Zi-O to commemorate Kamen Rider Ryuki was announced. Heck, Matsuda even [[https://66.media.tumblr.com/a37a005dee71a6784af8b6a66b52208f/tumblr_poincaGwJZ1qlljy8_540.jpg took photos with Geiz's actor Gaku Oshida]] and [[https://twitter.com/Matsuda_satoshi/status/1107157656395890688?s=19 dressed as the latter's character]] (which as a [[SugarWiki/FunnyMoments Crowning Moment Of Funny]], is an acknowledgement to multiple fans comparing Ren to Geiz, both physical and personality wise.)

* Kagami feeling down for losing to Yaguruma and Kageyama teaming up and thus stealing the Fourze and [=GingaFinaly=] watches. He confides to Sougo that he still feels inferior to Tendou and because of that he can't save the day like Tendou would. Sougo gives him a pep talking, saying he believes in Kagami as he's a warrior. And says when he becomes king, he wants Kagami to protect his people for him. Kagami actually bursts out laughing, saying not even Tendou said things that crazy.

* Kyosuke after stating his determination to save his pupil, Tsutomu the Hibiki Ridewatch is born. Kysouke takes it that his master, Hitoshi Hidaka is accepting him.
* Tomizo's invaluable teaching for Woz, who was still troubled about how to give proper blessing to Sougo was that Woz should be there for him, as his existence is already a blessing for Sougo.
* Sougo stops Geiz from transforming to let Kyosuke have a shot at talking Another Hibiki down. More so, Geiz trusts Sougo's judgement enough to let him make that decision. They really are a team now.
* After defeating Another Hibiki, Kyosuke and Tsutomu happily resume their training. Tomizo watching this, is inspired to take a pupil as well.
* Geiz humours Woz's idea of birthday party by wearing a gaudy party hat. He smiles a tiny bit too. Well, at least the corners of his mouth turn up slightly and he doesn't look as mad as usual. That's a progress.

* When OOO appears to do battle in the real world, he takes a moment to stroke the Taka Medal in his belt, and whispers:
-->'''OOO''': Ankh... Let's go!

** Even without the Ziku driver, Sougo is no less determined to protect people. He shielded a child with his body and was prepared to die doing so.

* The last time Rentarou is forcibly transformed into Another Shinobi, having attempted to resist Sworz interference, Sougo tries to protect him from Another Woz and the two fights along against Another Woz, until Another Shinobi pushes Sougo out of harm's way and decides to take the rest of the fight against Another Woz in his hands. Sure, he is defeated, but goes to show that, even after being turned into a monster, Sougo's words reached him and changed his future for better, ensuring he will become Kamen Rider Shinobi.

* The preview also features a shot of everyone (sans Black Woz and, understandably, Sworz) in the front room of the shop; while Tsukuyomi is standing next to White Woz, Geiz is notably standing next to Sougo behind the counter—implying that, despite the ending of 23, he, at least, returned to the shop and is still standing by Sougo.

* The scene of Tsukuyomi shooting in the bus was a major misunderstanding, she was trying to protect Sougo by shooting Sworz. Even if she put all that "We must stop Zi-O no matter what" front, she WouldntHurtAChild.

* While Amane was berserk as Another Blade, she absorbed both Kenzaki and Hajime's rider powers as well as their undead powers, turning them into plain humans, red blood and all. Now Hajime and Kenzaki are both [[EarnYourHappEnding free from their eternal burden]]. The [[ThereCanBeOnlyOne Battle Fight]] the Undead were made to fight in is finally over. Now Hajime and Kenzaki can talk to each other again without risking the end of the world.

** When Amane screamed for Kenzaki and Hajime to stop fighting, they managed to restrain their Undead instincts and stop. It's ambigious how long they could keep it up, but [[HopeSpot for the moment]] it all looked okay.
