Will Sou Yaguruma — Another Kabuto — lead him to the next one?
Or will it be Kamen Rider Gatack — Arata Kagami?
Meanwhile, a titanic meteorite is rapidly approaching Earth...
In space, Sougo is at a loss when he sees the second, and largest meteor approaching Earth. Woz suggests him to return to 95 DO to discuss their next plan. Meanwhile in the city, Geiz finds Yaguruma and tells him that the Worm Kageyama is using him for unknown purposes. Yaguruma doesn't care however, as he still consider Kageyama as his sworn brother. Woz explains his plan to Sougo: he will use Woz GingaFinaly Taiyou mode to incinerate the meteor from inside, but Sougo must carry him to space using FourzeArmor. Sougo asks Kagami's whereabout and Woz reveals that he is captured by Kageyama. Said Worm left a message to them, asking to meet him.
Geiz is still chasing Yaguruma and asks why he is so stubborn about Kageyama. The older Hell Bros explains that in the past, he killed Kageyama with his own hands and now swears to do it again if he must. When Geiz receives a call from Sougo, Yaguruma attacks him and escapes. Later, Sougo and Woz arrive at the promised place and Kageyama said that he wants to trade Fourze Ridewatch and Ginga Miridewatch for Kagami's life, as both watches are a detriment to his plan to bring the Worms to Earth. Sougo gives both watches to Kageyama... but it's just bait, as Woz sends Kodama Suika Arms to distract the Worm. In the confusion, Kagami is freed by Gatack Zecter and he transforms, immediately entering Clock Up mode to defeat Kageyama. But, Another Kabuto appears and fights him. Kageyama then takes both watches and they defeat Gatack before escaping.
Back at 9 5 DO, Kagami feels responsible for this fiasco and Woz explains that the ZECT member is actually from another timeline and Tsukasa Kadoya wants to merge with their timeline for some reason. Kagami then is reminded about his failure to become Kabuto 12 years ago.
Somewhere in the city, Kageyama explains to his sworn brother that the meteor is containing his Worm comrades and together they will conquer Earth. Yaguruma agrees because this will make the world a hell. But Heure appears and says that they cannot conquer the world. He freezes time and steals both the Fourze Ridewatch and Ginga Miridewatch. He then approaches Swartz to ask about stopping the meteor, but the leader takes both watches and leaves him.
In 2058, Tsukasa brings Tsukuyomi to her house. On the second story, they meet young Tsukuyomi... who then immediately freezes them both. The young girl is then taken away by a boy in a black trenchcoat and hat, which is then revealed as Tsukuyomi's brother. Suddenly Swartz appears and attacks Tsukasa, while giving back the two watches to Tsukuyomi, asking her to come back to 2019 as the world can't be saved without her power. Swartz leaves after saying that a new era will be born after this crisis. Tsukasa brings Tsukuyomi back and she immediately went to help Sougo. Tsukasa said that he finally understands what is going on, while Swartz is observing them says that his sister, Tsukuyomi is finally going to be awakened.
Back in the city, Kagami laments about his weakness as the Kabuto Zecter didn't choose him. But, Sougo still asks him to be his chief at protecting people, as he wants to be a king. This baffles the senior Rider as even his eccentric friend never spouted such nonsense. Tsukuyomi appears and gives Sougo the missing two watches, and the plan to stop the meteor is finally starting.
Geiz and Woz are still fighting against KickHopper and PunchHopper when Sougo, Tsukuyomi, and Kagami arrive on the scene. They both transform and the battle is continued as Sougo and Woz go into space. Woz transforms to GingaFinaly Taiyou mode and begins to incinerate the meteor. Kagami defeats KickHopper but Yaguruma transforms into Another Kabuto and Gatack is defeated. But Kagami's still won't go down, stating himself to be a warrior. This time, the Kabuto Zecter arrives and finally acknowledges him worthy of becoming Kabuto. Kagami transforms into Kabuto and proceeds to defeat Another Kabuto as Geiz finishes PunchHopper, killing the Worm.
In the space, the meteor and Worms inside are burned by Taiyou mode's power... but the meteor is still falling fast toward Earth. Tsukuyomi uses her time power to halt the meteor's fall, buying Woz precious time to finally crack the rock. Sougo then transforms into Zi-O Trinity and destroys it with a Rider Kick.
Kageyama laments the destruction of his Worm comrades as he begins to burn. Yaguruma asks the Worm to calls him "older brother" one final time, but the dying Kageyama rejects him. His false sworn brother finally dead, Yaguruma walks away solemnly.
As Kagami de-transforms, the Kabuto Zecter transforms into the Kabuto Ridewatch. He gives it to Sougo and promises him that he will come back as his underling when Sougo becomes king. Back in 95 DO, Junichiro said that the meteor crisis overwhelms him and he made too much emergency food. As Sougo and company wondering how to eat all of them, they hear a train screeching in the sky...
Episode Tropes
- Alas, Poor Villain: As Sou walks away after losing Shun for the second time, Geiz apologizes for his loss.
- Batman Gambit: It's hinted that the Time Jackers created Another Kabuto and started the whole thing with the Worms mainly to cause Tsukuyomi's time powers to grow.
- Break Out the Museum Piece: The Taka Ridewatch and Kodama Ridewatch return in this episode to distract Shun and free Arata with their Watchroid modes.
- Drama-Preserving Handicap: Arata got captured by the Hell Bros. at the end of the last episode, and Sougo and Woz had to surrender the Fourze Ridewatch and Ginga Miridewatch to Shun in order to get Arata back.
- 11th-Hour Superpower: Two examples:
- When Arata fails to stop Sou near the end of the episode again as Gatack, he refuses to just stand down because of his will as a warrior, causing the Kabuto Zecter to come to him and allow him to become Kamen Rider Kabuto.
- Tsukuyomi manages to use even more of her time powers to freeze the incoming super meteor in place outside of the Earth's atmosphere, giving Woz in Ginga Taiyou mode enough time to heat up the meteor and weaken it for Sougo to destroy as Zi-O Trinity.
- I Am Not Him: When Sou and Shun were both defeated at the end of the episode, Sou asks Shun if he would be willing to continue as his brother, to which Shun says that he is neither Shun nor his brother before dying.
- Lampshade Hanging: When Tsukuyomi and Tsukasa stumble upon a house in 2058, Tsukuyomi immediately questions why Tsukasa's clothes have changed, to which Tsukasa just remarks that he seems to be a cook.
- Pragmatic Villainy: The Time Jackers return the Fourze Ridewatch and Ginga Miridewatch, knowing that if the meteorite is not dealt with, there won't be anything left to rule over.
- Throw the Dog a Bone: After twelve years during which he was initially rejected, Arata is finally deemed worthy of being Kamen Rider Kabuto.
- Wham Line: When Tsukuyomi leaves with the Fourze Ridewatch and Ginga Miridewatch to help stop the meteor, Swartz watches from afar and says that it's fine for Tsukuyomi to have access to more of her time powers because she is his precious younger sister.
