The Academy's Weapon Replicator

A game no one has ever managed to conquer: Etius.

[GAME OVER]

The moment every possible strategy had failed... "Student Frondier?" I became Frondier, a mere extra in the game! Stores and replicates the image of an object. However, the replica is merely an illusion. All I have is the ability to replicate objects as illusions!

[Main Quest: Change of Fate]

You know the fate that awaits humanity... the day it will meet its end. Save humanity and change its destiny. "I'm supposed to change fate with this?!" Replicate everything. Forge a new destiny!
