A world full of turmoil, from politics between kingdoms, to dangerous threats like Demon Kings. A world filled with levels and skills, EXP and classes. In this world, something strange had occurred.

A secret experiment from an unknown organization was taking place, using forbidden magic and eccentric methods to achieve there goal. The superhuman. A hero.

In pure accident, they create immortals. Immortals with catastrophic powers, tens of thousands of them. Maybe more. Completely unpredictable without certain measures in place to control them. If they ever got out, the world would be in chaos.

Then they escaped.

(DISCLAIMER: There is multiple main characters and not one main character and also there are a lot of POV changes. Like a lot.)
