From the Start, I Transform into Kamen Rider Decade and Make the Tsundere School Beauty Cry

On the first day of college, Ye Feng awakens the Ultimate Knight System and obtains the Decade Driver. Only then does he learn that the world he has lived in for eighteen years is actually under invasion by monsters. This world is home to monsters found in the Kamen Rider universe: Worms, Another Riders, Jamatos, Gurongi, and more. Ye Feng is in luck. On his very first day at college, a beautiful upperclasswoman takes a liking to him, and the two sneak off into the woods together. He thinks it’s a romantic encounter. Turns out, it’s a disaster. The beautiful upperclasswoman is actually a monster. Just as Ye Feng is about to do justice on behalf of heaven, the haughty campus belle suddenly appears and accuses him of bullying a female student. There’s no other choice. For the sake of world peace, Ye Feng has to teach the meddlesome, haughty campus belle a lesson before taking down the monster. Little does he know, making the campus belle cry feels great in the moment, but the string of troubles that follows soon gives him a headache.
