I, Homura Akemi, Am the Demon King of Time

One day after becoming Homura Akemi, a pitch-black Kyubey appeared before her.

"My Demon King, I have come to see you."

"In the future, you will become Ohma Zi-O, who will plunder the histories of all Kamen Riders!"

Time flows on, and the girl's journey to find her true self stretches on without end.

The Heisei Kamen Riders who crossed through time: their powers are now passed down to the future.
