This afternoon around 3 PM, the world was shaken by strange phenomena witnessed across the United Nations' territories. A massive crack appeared as if the fabric of space itself had torn, covering both sky and land. This phenomenon emerged suddenly without any warning signs, resulting in significant casualties as numerous aberrant entities poured forth. Concurrently, some citizens, using an unknown power, managed to drive them away and caused the crack to disappear, but as of now, the cause and identity of these phenomena remain ambiguous. Tobias Heinle, the Minister of Internal Affairs, has temporarily classified this as an 'unidentified dimensional anomaly' and dispatched a joint investigation team to commence on-site control and analysis. Currently, citizens who fought off the monsters consistently testify that the crack appeared suddenly, simultaneously and without sound or vibration, and that they instinctively discovered how to use their newfound powers in moments of crisis. Authorities are urging citizens to refrain from excessive speculation to avoid unnecessary panic and have declared that they will keep all possibilities open in their investigation.

Star Rain changed everything due to the gates that opened 10 years ago. About 10 years ago, a gate connecting to another dimension opened in the sky and monsters poured out.
During that moment of chaos, the energy from the gate affected some individuals,
and they naturally manifested superhuman powers to close the gates from which monsters were spilling out.

…People praised them as heroes, but at the same time, they feared beings different from themselves, prompting the United Nations to take special measures.

The Union announced that under the leadership of Prime Minister Fabien Jean Benoit, they would incorporate superhumans into a national management structure through Union Headquarters.
They defined these individuals as Espers, systematizing their powers, classifying them into grades, and managing them regardless of their originating sectors to alleviate public anxiety.
Fabien promised to do his utmost for the safety of the citizens.

The establishment of the Union has changed the world.
With the introduction of systematic powers and heroes, the world quickly stabilized.
