Kamen Rider: Infinite Kuuga!

In the 21st century, Kamen Rider Kuuga brought Kamen Rider back into the public eye. Kuuga was the first Rider of a new era!

Some say every year's new Kamen Rider is always billed as the strongest. But in Ishimori's heart, there was only one strongest Rider: his very first. That was the ancient warrior transformed into by Yusuke Godai: Kuuga!

Then one day, Ishimori's fate changed. An unknown System appeared, turning him into the ultimate villain, Dark Kuuga. The Riders became his enemies, and they all disappeared, leaving only Kuuga, transformed into by Yusuke Godai.

"If I defeat every Rider, and Yusuke can gain the powers of them all, then my final battle will be against Yusuke! Win or lose, good or evil, Kuuga will be the strongest!" Ishimori thought...

System: "Ding! The Riders after Kuuga are about to cease to exist. The timeline is returning to the turn of the century..."
