The actor who portrayed Dan Kuroto will return to Kamen Rider in future episodes.
Tetsuya Iwanaga, who played Dan Kuroto/Kamen Rider Genm, whose popularity during Kamen Rider Ex-Aid’s run skyrocketed, will appear in Kamen Rider Zi-O.
In Ex-Aid, Iwanaga’s Dan Kuroto was a psychotic CEO who wanted to control a gaming company. The character would eventually go on to become an ally to the heroes, becoming a fan favorite for his eccentric behavior. Tetsuya Iwanaga will appear in episodes 9 and 10 of Kamen Rider Zi-O during its Kamen Rider OOO arc as Dan Kuroto.
Dan Kuroto will become Another OOO after the Time Jackers notice his intense lust for power. Kuroto’s company will “succeed” from Japan and become its own nation, with Kuroto turning those he does not like into Yummies, the enemy grunts seen in Kamen Rider OOO.
