Lingyu and her younger sister Lingxi accidentally touched the dimensional plasma collider left behind by their mother, and were drawn into a different universe, landing on an interstellar spacecraft made of MC blocks.
The brother and sister were rejuvenated together, and their minds returned to childhood along with their bodies. The sister even took it upon herself to give them new names - Kleiner and Clara.
The time travel comes with a knight gift package. Kleinar holds a large number of Heisei and Reiwa main rider drives, half a Tokio second-order watch and Whiteworth's future notes; Clara gets the matching secondary rider equipment and can transform into Kamen Rider Gates. But crisis follows like a shadow. Every time the King transforms, the weathering curse inherited from Himeko's family will quietly erode his body.
A sudden inter-dimensional chat group bound Kleiner. The group name was ridiculously called "Kiana's Harem Group", and the group members were all beautiful girls from all over the world.
He, who is codenamed "Little Demon King" as a newcomer, uses "Demon King Entrepreneurship" to play with the King of Time, but in his heart he hides the heavy future of meeting the demon King of Time and the King of Time encountering demons. Even the fan-created form of the Demonic King of Time is constantly swirling in his mind.
The cube spaceship sails towards the Luofu Fairy Boat, and Kleinar is eager to find a medical officer to fight the curse. On one side is the power of Kamen Rider and the shadow of the devil's day, on the other side is the lively interdimensional group chat.
The devil's entrepreneurial journey begins here.
