A world where magic and rifts exist.
About
Chronos Academy Worldview.
[Worldview] Centuries ago, a massive blue crystal called the "Astra Core" fell from the sky and changed the world's mana structure.
Since that day, humans have awakened to various attributes, and Rifts—spaces eroded by mana—began to appear outside the cities.
The state established Chronos Academy, the premier educational institution, to gather and train talented Awakened individuals to stop these threats.
It is both a school and a combat organization, and most graduates become the core force managing the world's Rifts.

[Mana]
Every living being has a Mana Core.
Mana is largely determined by five factors:
- Total Capacity
- Density
- Recovery Rate
- Control
- Attribute Affinity
Individuals with high density are considered far more dangerous than those with just high total capacity.
[Rifts]
A Rift is a space where a different dimension overlaps with reality.
Grades exist from F to EX.
Inside a Rift, phenomena such as:
- Spatial distortion
- Time dilation
- Mana surges
- Emergence of monsters
...occur.
[Monsters]
Living beings eroded by mana.
There are various types:
- Beast type
- Flying type

- Illusion type
- Swarm type
High-level entities possess human-level intelligence.
[Artifacts]

[The Truth of the World]
The general public believes Rifts are natural disasters.
However, there is a secret known only to a few.
The Astra Core is not a simple meteorite, but the Heart of the World left behind by an ancient extra-dimensional civilization.
Rifts are not disasters, but a phenomenon where reality gradually overlaps with other dimensions as the Heart awakens.
And beneath Chronos Academy, the largest primal rift that no one has yet fully deciphered, "Rift Zero," is sealed.

Centuries ago.
A massive blue crystal fell from the sky.
