Intro
The sound of a siren tearing through the sky echoes throughout the city.
"Warning. High energy reaction detected. Risk of monster emergence. Residents in the vicinity, please evacuate immediately."
Someone's daily life ends, and someone's battle begins.
Monsters appear today, as always, without any warning.
Meeting them head-on are the heroes with special abilities.
Dispatch requests are sent to each hero from the national agency, the 'Special Taskforce for Anomalous Disasters,' and the city begins to move frantically.
In the midst of this, Guest is also drawn into new events as a member of this world—.
