Soranica Ele

『The Floating Academy City Nora』 is an artificial island floating on the sea.
Its population is a mere 4,000 people.
On the island stands an academy, and aside from a handful of adults, everyone else is a student.
The students there share one thing in common.
That is, "possessing wings."
Every student is born with wings through a "Sigil," and the wings grant their bearer an ability.
The power to fight, the power to heal, the power to destroy, the power to create...
—All of them are sigils destined to meet their end.
Within the circular arena that serves as the academy's symbol, there is a legend.
It is said that "whoever achieves 13 consecutive victories in the arena shall become the 'Ark (Arc).'"
The "Ark (Arc)" will guide the world when its end arrives.
Can they guide the world?
And to where will they lead it?
Hayasaka Tsukasa is an unremarkable second-year student at the academy.
Except that he bears a somewhat different sigil.
His sigil—Soranica Ele (Wings and the Day of Finality)—has never materialized.
He is also the only person in the academy without wings.
But setting that aside, life must go on, of course.
Summer vacation. A time to sing praises to the sky.
The life of the world is about to end.
His reality has long since fallen apart.
Abruptly, he declares it with complete naturalness.
"The world is about to perish."
What are they doing as the end approaches?
Several diverging stories within the closing finality.
Ophelia yearns for rebirth, Zenobia yearns for destruction. Mei seeks universal love, Mimei seeks life. Kaguya rejects death, and Saya protects the everyday.
And Hayasaka Tsukasa—
seeks an answer from the end of the world.
The countless repetitions of the end born for that purpose.
The antinomies chosen by the world.
Until ten antinomies, ten thousand antinomies, a hundred million antinomies.
Like a waltz.
In the diverging futures, they sigh, grieve, rejoice, love each other, and die.
In the chain of momentary reincarnations, what do they see?
The end cannot be avoided.
But still, they continue to live.
Why?
The repeated end meets its conclusion once more.
At the finale, can they spread their wings and soar into the sky?
Mighty wings. Wings more beautiful than anything else.
The world ends.
At that moment, what do you see in the heavens?
