Ye Xian is an ordinary college student. An accident caused him to travel to the world of "Happy Cool Baby". What's even more outrageous is that he was selected by Kamen Rider Kiva's belt, becoming the only Kiva in this world without tooth vampires.
After watching the animation, he thought he could rely on his "script advantage" to get by, but on the first day he met another time traveler-Jin Xian. Coming from the real world like him, he got the more dangerous Dark Kiva system. Jhinxian chose to burn his life to pursue the so-called "throne", using his own pain and the fear of others as fuel.
The first time the two fought, Kiva was almost beaten until her armor shattered.
At the same time, changes were also happening in the Kubao Kingdom. Marshal Akubos secretly illegally collected negative emotional nuclear energy. Princess Rabi was sent to the earth by her father in advance to study human emotions, but she discovered that there was a purple energy on the earth that even Kubao technology could not completely purify - it was the negative emotions spread by Dark Kiva.
A time traveler who doesn't want to be a king.
A fellow countryman swallowed by darkness.
