Aegis ship

Mugino Shizuri.

Academy City’s #4 Level 5. Her power was known as Meltdowner. Electrons always appeared as either a particle or a wave, but her power let her emit them while they were fixed in a pure state that could not distort into either form. That attack known as the Particle-Function Waveform High Speed Cannon held enough destructive power to slice apart an Aegis ship.

Had she acquired such a power because her personality had been brutal from the beginning or had she gained a brutal personality from acquiring such a power? There may have been no one who could answer to that chicken-and-the-egg question, but there was no mistaking the fact that Mugino Shizuri currently had a personality that befitted the #4 Level 5.
