In Kamen Rider Zi-O, I Talk to the Old Demon King from the Start!

Su Yu transmigrates into Kamen Rider Zi-O and obtains an Acting System!

His very first role turns out to be Hades!

To play Hades more convincingly, Su Yu has no choice but to follow the law of the jungle: the strong prey on the weak, and only the fittest survive!

This earns him the attention of the Old Demon King...

The Old Demon King crosses time and space to speak with Su Yu, then makes a wager: which of them will be the true king?

Woz: "Celebrate! The true King Hades has been born!"

Gai: "To change the future for the better, Zi-O, let us help you become the Demon King of supreme benevolence!"

Tokiwa Sougo: "My dream is to become a king! A king of supreme benevolence! Hades, I will defeat you!"
