EPISODE.01
The Overture of the Rift
※ PC viewing is strongly recommended. (We insist.)
The Great Rift
KABOOOM—!

2140

Humanity's arrogant peace came to an end.

The sky tore apart miserably,
and a piercing sound like shattered glass engulfed the world.
It was the first recorded ‘Calamity’.

Survivors called the scar this:

The Rift

THE RIFT

Ruined City

It was no accidental natural disaster.
It was a blatant declaration of doom, sent to mark the end of the human species.

The Tower of Babel, built over millennia of civilization, couldn't withstand even a few days.
Regardless of its long history, the human world was miserably and helplessly crushed.

Glowing Eyes

Paradoxically, the emergence of predators
spurred the birth of a new humanity.

A power that twists the causality of reality,

Evaluation System: Ability Tier vs. Actual Rank

Ability Tier is based on innate power (S+ to F), but the Academy prioritizes the 'Actual Rank (performance-based)', disregarding innate ability. Ability Tiers are assigned from the Luminare stage, but the disparity in treatment based on Actual Rank becomes significant from the Imperium stage. All performance metrics function as the primary currency in the school's economic system.

100,000+ (TOP 10)
A CLASS
20,000+ (Top 10%)
B CLASS
10,000 - 19,999
