Continuity and Placement


"According to this book... Rejoice! It's your birthday! Birthday boy, Sougo Tokiwa, is destined to become the demonic king of time, Ohma Zi-O. In order to obtain power befitting of a demon king, he must gather the remaining five Watches. This time he must obtain this Rider's power, Kamen Rider Hibiki, but not the Hibiki himself, but of Kyosuke Kiriya..."
Black Woz[src]

In a game center, a young man is approached by Uhr. The Time Jacker states that the young man used to have a dream to become an "oni", and he will help him to achieve that dream... transforming the young man to Another Hibiki.

Woz is on a distraught because this is Sougo's birthday but he doesn't know how to celebrate it as befitting of the future Demon King. Geiz and Tsukuyomi don't really care, however, but Woz gains an unlikely ally in Junichiro Tokiwa who also wants to surprise Sougo. As they talk about this, Junichiro brings Sougo's primary school yearbook. Sougo then remembers his old friend that is weirder than him, in that he wants to become an "oni" in the future, and he learned under a man named Hibiki. Geiz remembers a Kamen Rider based on oni, Kamen Rider Hibiki, and said that this is a clue to the next Ridewatch.

Sougo and Geiz go into the city looking for Sougo's old friend. Geiz explains that the being called "onis" are from an ancient organization pledged to protect the peace. Suddenly Another Hibiki attacks them. Sougo transforms into Zi-O KuugaArmor while Geiz transforms into WizardArmor. In the midst of battle, suddenly a man separates them, and he transformed into an oni, Todoroki! The oni has the upper hand against the Another Rider when someone attacks him with a flame, enabling the monster to escape. Then, another man named Kiriya Kyosuke appears before them, introducing himself as Hibiki. Realizing that this man is his old friend's teacher, Sougo takes Kiriya to his home.

In 95 DO, Sougo explains that he needs Kiriya's Ridewatch, but Kiriya didn't found anything like that. He does agree to give Sougo his Ridewatch though, but he must prove himself worthy to become an oni. Overhearing that, Woz also wants to come as he must train to celebrate an event grandiosely, making Geiz trying hard not to laugh.

Sougo, Geiz, and Woz go to train at Kiriya's when Woz tries too hard and interrupting Sougo and Geiz's training. Sougo proves to be too weak for physical training and he protested to Kiriya, stating that he needs the Ridewatch to become king. The mentor just said that he doesn't worthy to have his Ridewatch. He leaves and reminisces about his past pupil, the boy named Tsutomu.

Meanwhile, Tsukuyomi found Todoroki. She asks about Kiriya, in which the senior oni said that Kiriya is not Hibiki and he is not to be trusted. Another Hibiki reappears and attacks Todoroki again, and he almost wins once again before Uhr reverses his finisher using time-stopping power.

Sougo and Geiz, called by Tsukuyomi, arrive on the battle site. Geiz states that Sougo doesn't have Hibiki Ridewatch, so he must transform into Zi-O II to defeat the Another Rider. Geiz transforms to GeisRevive Shippu to chase the monster, and they both launch a Rider Kick to defeat Another Hibiki, revealing his identity as Tsutomu, Sougo's friend. Sougo undoes his transformation to help Tsutomu, but Uhr reinserts the Hibiki Ridewatch to him, transforming him back.

As Geiz goes to attack the resurrected Another Hibiki, Kiriya arrives and transforms into a white-colored oni to protect his pupil much to his surprise when Another Hibiki assaults him brutally instead.


Guest Cast

Suit Actors

Forms and Collectibles Used




  • When Sougo summons KuugaArmor, the CGI effects show "RIDER TIME" and "RODER TIME" instead of correct "ARMOR TIME".
  • After being knocked out of his transformation, Todoroki is still wearing clothes, despite an Oni's clothes normally being destroyed by their transformation.
    • The reason of this change might due to censorship reasons.

  • This is the final episode of Kamen Rider to air in the Heisei Era of Japan. Starting the week after, the show will enter the Reiwa Era.
  • The air date is same as Sougo Tokiwa's birthday, April 28th, which the episode also takes place on.
    • Like Rina Akiyama who reprised her Agito role for the first time, this episode marks Yuichi Nakamura's first return to the role of Kyosuke Kiriya since Hibiki's end. Coincidentally, both Nakamura and Akiyama were co-stars in Kamen Rider Den-O and continued to reprise their roles on many occasions after Den-O's end.
  • The Rider Armors used in this episode relate to the original Kamen Rider Hibiki series.
  • This isn't the first time Sougo and Geiz attach their Ridewatches into their Ziku Drivers before equipping them to transform, as this practice was first done by Sougo himself in Heisei Generations FOREVER and then by Geiz in episode 16.
  • Since the new status-quo with the Another Riders being born in 2019 had begun with the Blade tribute arc, this is the first arc since to not have the main actor reprise his role. In this case, Shigeki Hosokawa does not return as Hitoshi Hidaka.
    • Hosokawa's absence is largely attributed to his strained relationship with producer Shinichiro Shirakura during the filming of Hibiki.
  • Final TV appearance of Zi-O Ex-Aid Armor and Geiz Wizard Armor. 
    • Only TV appearance of Zi-O Kuuga Armor
