In episode 20 i saw White Woz hand over Quiz and Shinobi Miridewatch to Geiz, but an electrical force began to shock Geiz as he began to see his future self as the SAVIOR!!!!

And this is what Geiz saw his future self in his eyes.

White Woz said, if the 3 different ridewatches are collected the Demon King Oma ZI-O will fall from his throne. That means 2 Miridewatches has been collected and only 1 left and that is Kamen Rider Kikai, hail from year 2121! And i believe those 3 Miridewatches could be a component for Geiz Revive Ridewatch!

Woz, Sougo, Tsukuyomi are at Sougo's uncle workshop and Woz handover the mysterious ridewatch to Sougo's uncle and ask "Can you fix it ?"
