Destiny's Echo

Meet Lu Xiaobai, a run-of-the-mill high schooler who gets blindsided by an attack from "Xiao," a higher-dimensional envoy with unclear motives. He's basically dying when he unlocks time-based powers and gets pulled out of the fire by his own future self, a guy who goes by "Cang." That's the first episode hook — you're fighting alongside a version of yourself who already knows how everything plays out, which immediately raises a ton of questions about what went wrong the first time around. Turns out Lu Xiaobai's dead father ran something called the Bureau of Demon Defense, and now that responsibility falls on him. So he goes from normal kid to leader of a supernatural defense organization while learning to control time powers he barely understands, with his future self acting as both ally and walking spoiler. The vibe is action-packed urban fantasy with a time travel throughline that keeps things from feeling straightforward. Think along the lines of Bleach's "ordinary teen inherits a world of combat" setup, but with the timeline manipulation tension of Steins;Gate woven into the fights. If you liked the escalating stakes and mystery layering in Jujutsu Kaisen, this ONA from Yien Animation Studio scratches a similar itch. It's a Chinese original animation, so the pacing and aesthetic lean donghua rather than traditional anime, but the premise is strong enough to carry you through that adjustment period.
