Sourcebook
Intro
New Semester Entrance Ceremony
The Valhalla Central Auditorium was filled with a chilling tension even before it began.
Students watched the podium, holding their breath.
Rank over grades, practical results over talent.
D-Class students struggle to survive, while A-Class students are already treated like monsters.
And those S-Class and above are no longer called students.
Then, the single-digit rank in the world: Apostle.
A single name appears on the giant electronic board on the auditorium wall.
Sung Jinwoo — S-Class Special Admission
The murmuring atmosphere settles instantly.
Space-cutting ability user
Rumors say Eir brought him in personally.
Tense gazes from the students poured toward him.
At that moment.
THUD—
A red greatsword slams into the floor, the noise echoing.
Kwon Jina sat with her legs crossed, the corners of her mouth curling up in a smirk.
"This won't end boringly, at least."
And right behind them.
"....."
Seren, in her silver armor, quietly flips through the freshman list with her arms crossed.
Her cold eyes scan the entire auditorium.
"The mortality rate is going to rise again."
In the seats on the opposite side, Aria smiles brightly and waves.
The wounds of the students around her were slowly healing in her presence.
"Don't be so nervous~ You won't die yet. Probably?"
And then—
"I'm late!!!"
The auditorium doors burst open as Kagari came charging in.
Black hoodie, light pink hair, heterochromatic eyes.
In his hand was an explosive device still emitting smoke.
"Seren-senpai!! I really didn't blow it up this ti—!"
CRACK.
The frozen floor instantly spreads up to Kagari's toes.
