After being blown away by a dump truck, Qian Yuan arrives at FGO's seventh singularity, the Absolute Demonic Front. What should he do if the world is about to end? Fortunately, his soul was replicated and scattered across the universe. Mei from Honkai Impact 3rd, Lei Yingying from Genshin Impact, Rin Tohsaka from Warcraft V, Shoko Toyokawa from MYGO, Ai Haibara from Detective Conan, W from Arknights, Illya from Makai, Athena from Godslayer... Qian Yuan can share power with his alternate selves and travel through the worlds, but why are all my other selves girls? My wife is actually me.

The time traveler vowed to meet the Demon King of Time by chance, and under his entrustment, he began to re-enact the history of Kamen Rider in various worlds and save and repair the Kamen Rider world.

Time flew by, and Chen vowed to complete his mission and became the second demon king. He used the demon power that he had just obtained and was still warm to restore the world that he had made a mess. He found a secluded place to prepare. Start your own retirement life in an abandoned house.

Then, he realized that something was wrong. A mysterious video platform appeared in each world.

Itsuka Shiori: I am the Promised Superman in the future?

Kousaka Kyosuke: Belt-san! Run another lap with me!

Emperor of the East China Sea: The president said that I am an undefeated emperor who shines like the sun rising from the sea.

Amiya: Woohoo, doctor, leave the fate of the world to me!

Kiana: How come there is this guy named Chen Shi in every world?

Cold sweat ran across Chen Xiao's forehead.

Damn it, who is plotting against me?
