Time demons are a premise with teeth. Victor and Kiri aren't fighting to save the world, they're fighting because people keep trying to rewrite their own histories, and every timeline correction births something that eats entire moments out of existence. The show commits to its concept: time manipulation in combat means fights where both sides are literally erasing each other's actions, strategies that unmake themselves mid-execution, and the brutal realization that fixing the past always costs someone else's future.

Wishing to turn back time and fix the past has a deadly cost: it draws demons called Horologues that feed on human time, and they are attracted to people's regrets. Standing against them are the Chronos Rulers, a group of warriors including Victor, Kiri, Mina and Blaze, who fight with the Oath of Time, an item that lets them speed time up or slow it down. When Koyuki Honda, who lost her only family when her brother died years ago, visits his grave before her graduation, she meets brothers Kiri and Victor Putin chasing a strange creature. Curious about a cemetery legend that a midnight wish under the clock tower during a full moon can turn back time, she decides to make her wish and learns the legend is a trap the Horologues use. Adapted from a manhua by Pon Jea, the action drama keeps the brothers hunting demons to protect humanity.
