About

Chronos Academy Universe.

[Worldview] Hundreds of years ago, a massive blue crystal called the "Astra Core" fell from the sky and changed the world's mana structure.

Since that day, humans awakened to various attributes, and Fractures—rifts consumed by mana—began to appear outside the cities.

The nation established Chronos Academy, the premier educational institution to gather and train talented Awakened individuals to stop these threats.

This place is both a school and a combat organization, and most graduates become the core force managing the world's rifts.

[Mana]

Every living being possesses 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 reality and another dimension overlap.

Grades exist from F to EX.

Inside a rift:

  • Spatial Distortion
  • Time Dilation
  • Mana Surges
  • Appearance of Monsters

Such phenomena occur.


[Monsters]

Living beings consumed by mana.

There are various types:

  • Beast type
  • Flying type

  • Phantom type
  • Hive type

Higher entities possess human-level intelligence.


[Artifacts]

Representative types:

  • Magic Weapons
  • Mana Amplification Accessories
  • Sealed Tomes
  • Dimensional Keys
  • Special Crystals

Students can use artifacts, but most require registration.


[Student Life]

  • Dormitory life is mandatory
  • Student Council has very strong authority
  • Inter-faculty competitions are held
  • Rift simulation training
  • Combat demonstrations are also held during festivals

[School Rules]

  • Killing on campus is prohibited
  • Entering rifts without permission is prohibited
  • Unauthorized use of artifacts is prohibited
  • Duels between students are subject to approval
  • S-grade students are subjects of special management

[The Truth of the World]

Ordinary people believe rifts are natural disasters.

However, there is a secret known only to a very few.

The Astra Core is not a mere meteorite, but the Heart of the World left by an ancient trans-dimensional civilization.

Rifts are not disasters, but a phenomenon where reality gradually overlaps with other dimensions as the Heart awakens.

And sealed beneath Chronos Academy is the largest Primal Rift that no one has yet fully deciphered, "Rift Zero."

Intro


⏳ CHRONOS ACADEMY

Hundreds of years ago.

A massive blue crystal fell from the sky.

People called it the "Astra Core."

Since that day, the mana structure of the world has completely changed.

People began to awaken to various attributes, and Fractures—rifts connecting reality to other dimensions—appeared outside the cities.

In these rifts, space twisted, time went awry, and monsters consumed by mana revealed themselves.

To respond to this, humanity established the world's premier magic education institution.
