There is a "causal court" in the universe that judges all abnormal events. There are seven "original judges" under the court, each representing the absolute laws of the seven realms.
The selected people become "jurors" and enter various collapsed space-time fragments to find "causal breaking points" and repair them. There is also a saying among jurors: "The court is not the savior, it is itself the original sinner."
Purpose: "The court is not the savior; it is itself the original sinner."
