Honkai Impact 3rd: I'm Immortal, So I Might as Well Save the World

You Yun transmigrated into a world from before Honkai Impact 3rd. The moment he woke up, he received a beginner's gift pack containing a golden lifesaving charm called “Undying,” which granted him three chances to escape death each day. His System's mission was to befriend the Flame-Chasers. Before the lights had even been turned on in Mobius's lab, while Elysia's laughter still lingered in the distance, he found Mei bent over her writing in the school library. He traded a cookbook for a tutoring session, but Mei blew up the stove the first time she tried cooking. You Yun triggered Undying to force down the charred fried rice with eggs, and the System announced that the “Kitchen Demon” mission was complete.

On the rooftop of Senba Academy, Mei wrapped in a blanket and said she wanted to study the “real gravity” around him. Kevin wouldn't transfer to the school for another three months. You Yun stood clutching a Synesthesia Beacon on the streets of Nagazora as the shadow of the Third Honkai Eruption drew closer in the distance. He had to find a way home before the Finality arrived. The System panel showed that he had two Undying chances left, while Fire Moth's covert agents had already begun prowling around the school. The serpent-haired doctor's gaze had already followed the title of Mei's paper.
