Even if... 'I' should disappear one day... I still want to save 'you'...!

...I've had enough... I'm scared... I don't want to die...!

...Why...? Are you stupid...? Why would you go that far...!

Why... are you saving me...?

...It was always like that.

"You" always end up shielding "me"—who you shouldn't even know the name of—and falling in battle.
No matter how many times it repeats... no matter how much we overcome... "you" are always there, always saving "me."
...Even if it means "I" have to sever the world countless more times. ...Even if I eventually reach my limit and disappear into nothingness.
"So wait for me... Guest...!"
Rank 181. That girl is an "Anomaly" who should not exist. The vines on her body are "Terminals" and "Anchors." To Guest, she is the "precious" thing left behind in a history that "could have been."
A faceless phantom who appeared from outside the "World."
The partner girl is dead, the "Will of the Academy" has long vanished... and not even a "common small miracle" occurs. The man who bought the "value" of the world now stands without an enemy.

—Again. ...It failed again...
A disastrous scene spreads before my eyes. ...I've rewritten "possibilities" countless times, discarded them, and repeated the parasitism again, ...and yet it still wasn't enough.
Hahahaha!! What's wrong!? Is this the end? My friends.
It was a situation that could truly be called checkmate.
For that faceless phantom had just finished collecting all the "value of this world."
Now that Delos is gone! You all can't even dream of defying me anymore!
—The faceless phantom. Lewis steps on Guest's head. Guest could no longer even make a sound.
—That was the day... my fate changed. ......The day an infinitely long battle began.
Haah... haah...!!
The "Calamity" that manifested from outside the "World"... it was true despair. A monster that crushed mountains and tore the heavens. A beast that all the forces in the academy united to face. There was nothing I could do in that place... and yet. I hated myself for being able to do nothing in the midst of it all. So... at least. If I could at least help the injured who were fighting, I used the only "Ability" I possessed... "Possibility Reception," and called out to all sorts of people.
Someone...! Someone who can fight...!
...I was desperate. I was frantic.
