==Synopsis==
"If you throw away that belt, then you'll never become the demonic king... You can change the future..." Sougo after hearing the words of Ohma Zi-O was faced with an excruciating decision. Strangely the DaiMajin that exists to destroy the world still exists. After witnessing the crisis that Geiz is facing, Sougo makes his decision. What will Sougo choose to do?!

==Errors==
*In both times Decade Wizard Form used Final AttackRide: Wizard, it didn't ignite a finisher (like Kick Strike), but merely Wizard spells (Big and Bind respectively), which should have been activated by AttackRide cards instead.

*This is the final Zi-O episode to air in 2018. This is also the first episode to air after the premiere of Kamen Rider Heisei Generations Forever.
*This episode reveals that Heure's Time Mazine can also transform into Iguana Ghostriker (with the motorcycle part being replaced by Ora's Time Mazine riding on it).
*This episode is the first time that Geiz called Sougo by his first name instead of Zi-O. Much like Hiiro Kagami did in Ex-Aid episode 23.
**Geiz would call Sougo by his given name again in the season finale.
*This is the first instance where a Ridewatch is placed first into the Ziku-Driver before donning the belt to transform. This would be later seen in Kamen Rider Heisei Generations Forever and in episode 33.
*Tsukasa would return 10 episodes later.
