Elliot Webb, a history professor, is transported to a fractured multiverse after touching a mysterious mirror shard. Unlike typical Isekai heroes, Elliot doesn’t gain magic or a grand destiny—he finds himself in a broken world where time is unstable, reality shifts, and each dimension operates by different laws. To navigate this chaotic existence, he must piece together lost knowledge from scattered realms while uncovering the truth behind the mirror shard.
As he encounters survivors from other shattered worlds, Elliot learns he is a "Keybearer," capable of potentially healing the multiverse—but doing so could repeat history's mistakes. With a mysterious force watching his every move, Elliot faces tough moral decisions, questions his own identity, and discovers that the key to saving—or destroying—this fractured reality lies in letting go of the past and forging an uncertain future.
