Honkai Impact 3Rd: Saving the World in the Name of Love and Peace

[Honkai universe + Kamen Rider + Previous Era + Current Era + parallel worlds + making up for regrets + multiple heroines] After unexpectedly transmigrating into the world of Honkai, Xingyuan Youyu saw the Valkyries who had always been by his side. Clenching the Build Driver in his pocket, he tried his best to do something. An obsession. A wish. Rewrite the fates of Cecilia and Sirin, and save the lives of innocent people. Extend Himeko's life and save the teacher he held dear. Make up for the Flame-Chasers' regrets, and connect this world's past with its future. Stop crises that have yet to happen before they can take root. Keep tragedies that should have occurred from happening again. And write his own Rider legend in this world. But on the boy's path toward a better world, he discovered that the world he saw was not as simple as he had imagined. The Pandora's Box by the table, and the Evolution Driver he was assembling. Xingyuan Youyu toyed with the still-sealed Black Hole Trigger in his hand, along with his coffee shop, which had yet to receive a single customer. Looking at Sirin and Bella sprawled on the floor after taking just one sip of his coffee, Xingyuan Youyu could only stare in disbelief. “I've got the Sento Kiryu script, right?” Outside the door of the Nascita Cafe, a passing Kamen Rider glanced up at the shop's sign. A cryptic smile appeared on his face. He waved, then turned and walked toward the dimensional wall. “Don't disappoint me, kid.” This is simply the story of a genius boy from another world who fights for everything beautiful in the world, and fights only to protect the people he loves.
