The Age of Monsters: The King of Time Wrecks Me, a Scumbag!

In this world, everyone has a chance to awaken the power of various monsters and Riders when they turn eighteen. There are countless kinds of creatures, including Gurongi, Orphnoch, Inves, Ghouls, parasites, and vampires. Lin Ye, who has just fallen out with his younger sister Ye Lingxue, awakens the strongest Rider System. From the start, he gets the Decade Driver, mutation cards, and a female Rider development panel. Oh, Zi-O? Sorry about that. “Kamen Ride: Another Decade.” [Kamen Ride: Another Decade!] My name is Ye Lingxue. Tomorrow I come of age, and my scumbag brother has stolen yet another one of my best friends. Now I have no one to keep me company. If that's how it's going to be, we'll each go our own way. [Time Mazine] Henshin! [Zi-O!] Brother, your end is here!
