Nineteen-year-old Shao Qi was just a tokusatsu fan who had recently graduated high school. Night after night, he had dreamed up his own hero in a design notebook: Kamen Rider Chronos. Then he transmigrated. When he awoke, he was standing on a street in Changkong City, and the design book in his hand was still glowing. The Third Honkai Eruption was only a few months away. He had played Honkai Impact 3rd: Changkong City would be consumed by flames, the girl who smiled and cried, "For all that is beautiful in the world," would march toward the end, and gentle Mei would be torn apart by lightning and become a Herrscher. But his memories were only fragments, with no clear dates or order. He wasn't an all-knowing god, just a bystander carrying a broken spoiler. Still, that was enough. The design book had truly materialized at his waist: the [Chrono Driver] he had drawn himself was clicking into action. "Past! + Present! + Future!" Data streams coiled around him as silver armor covered his body. Amid the roar of gears, he stood in this world for the first time. He wasn't a saint, a variable, or a chosen savior. He was just a boy who had transmigrated with an unfinished design. But he had made a vow: every drop of blood and every tear this world was destined to shed, he would rewrite with his own two fists, one by one. As the gears turned backward, the Honkai had yet to reach its end. "My time begins to run backward from this moment."
