He became the Demon King of Time, defeated all the Kamen Riders, and came to the world of the Holy Blade. He became the boss behind the scenes who controlled everything behind the scenes.

Shenshan Feiyuzhen: Senior Jiang Chen, I also want to become stronger!

Shindo Rintaro: The Demon Tokio, a guy who is extremely scary.

Kamishiro Reika: He is the demon king I worship...

Facing the countless Kamen Riders in front of him, Jiang Chen slowly raised his right hand.

Jiang Chen: I am not the kindest and best king, I am the lowest and evilest devil!
