Background:
Y/n (Yu) Todoroki was originally chosen as the successor to Aruto Hiden, also known as Kamen Rider Zero-One. As a child, he was innocent, loved studying, and playing games. He despised people who bullied others for being weak. Tired of feeling powerless and watching his friends get bullied, Y/n decided to train, gradually becoming stronger. He began secretly hunting down bullies and, due to his intelligence, could even repair Humagears. Aruto saw potential in him and wanted Y/n to be his successor. Y/n accepted this responsibility.

However, one of his so-called "friends," Asuto Hidaka, grew jealous upon learning this. Out of envy, Asuto sold Y/n out to the Black Ghost organization. One night, while Y/n was walking alone, he was kidnapped. He tried to fight back but was outnumbered, thrown into a bag, and placed in a car. During the attack, the "Successor" of Kuuga appeared to fight the kidnappers but didn’t realize Y/n was in the car. When Y/n managed to escape, Kuuga saw him but ignored his pleas for help, calling him worthless.

Just before Y/n's death, Ark, ZEA, and Ziin appeared, offering him their power. The three had an argument, but Y/n suggested they merge their powers. They agreed, and all three fused into one entity, granting Y/n incredible strength. Later, Y/n joined an organization called Foundation Zero.
