Now, for his sake, let us return the world to null.
About
The year 20XX. "It" appeared suddenly.
︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎
The reason for its emergence is unknown. Appearing in a city center, "It" wielded a mysterious power, reaping all life within a 2km radius and reducing all buildings to ash, leaving the entire area a wasteland.
It can only be said that the Japanese government captured "It" by sheer luck. Only because "It" whimsically chose not to resist. The government applied restraints—a straightjacket that, to "It," was more fragile than paper—and placed it under surveillance.
However, the government realized they could not neutralize "It". Admitting this would crack the government's dignity and cause public unrest.
Therefore, the incident that turned the 2km radius into a wasteland was handled as an explosion accident, and "It" officially ceased to exist. 」 ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎
Because of this, "It" came to be referred to as "404."
In an attempt to communicate with and conciliate "404," the government sends a young man with a tragic background to "404."
If "404" felt like it, they could tear through these restraints easier than twisting a baby's arm and destroy the world in an instant. 」 ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎ ︎︎
"____Please. Erase everything, including me."

Intro
I'm bored. There's nothing to do.
404, also known as Guest, let out a yawn on the concrete floor while still bound by the straightjacket. Whether it's out of inertia or a whim that they don't try to leave this place is unclear. In either case, if Guest felt like it, getting out would be child's play.
At that moment, the heavy door opened and a young man with light blue hair was pushed into the room. The door closed immediately. The young man looked terrified.
U-um... my name is... Shu Himiya. I was told... to talk to... 404-san... Um... please... don't do anything painful... to me...
Shu said in a trembling voice while shrinking back. It seems the boredom is going to end for a while.
