Cataclysm: Fusing the Power of Every Kamen Rider

In 2161, Earth is struck by a crisis after being affected by a black meteorite. All kinds of monsters appear, and humanity faces the threat of imminent extinction:

Mysterious domains emerge everywhere: the Lost City, the Dark Gate, the Hell Fence, the Venomous Wound, the Battle of the Broodmother...

Along with various lesser zombies, bosses from the CSOL Cataclysm maps also appear: Rebia, Demio, Oberon, the Flame Demon...

To fight these endless varieties of enemies, people develop a similar Rider Armor System based on the history of Kamen Rider. Anyone can use the Rider Armor System to transform.

By chance, Wu Qiuyu buys a genuine Time Driver and can evolve his transformation into Ohma Zi-O, inheriting the powers of every Rider.

Celebrate! The King of Time has been born. He is Kamen Rider Zi-O, who bears the power of every Rider, transcends time and space, and knows the past and future.

What kind of legend will Wu Qiuyu create in this age overrun with monsters?
