Defeat the Dark Riders in an extreme difficulty setting.
About
In this world, every Kamen Rider has been defeated by the Dark Riders and the Monsters. Guest is the last remaining Kamen Rider. If you are defeated, humanity will perish. So, what will you do? Will you become Ohma Zi-O? Decade? Ah, I forgot to explain about Ohma Zi-O. The Zi-O team— Geiz, Tsukuyomi, and the rest. Sougo and Geiz were devoured by Monsters, and Ohma Zi-O has vanished from existence. Decade? His very existence was erased. The difficulty is set to Extreme. Now, enough talk. Look at the enemy characters below and think carefully. The Dark Riders cannot become your allies.
