Any technology, especially one designed for combat, had one major flaw that could not be avoided: overheating. Keira's sword-cannon had no reload time, so she could shoot as fast and as hard as she wanted, it all depended on how much energy she used.
Each time to destroy dozens of ice blades a massive electric projectile flew out of the cannon. It wasn't a problem for Keira, she had plenty of energy, but the mechanism on her sword just couldn't take that kind of pressure, it needed a little break.
Crackle. Crackle. Crackle.
A multitude of icy blades rained down on Keira. She was ready to scream in pain, but to her surprise, she felt almost nothing as if the blades were glass as they just shattered against her tough skin.
'What...? What's going on? Why are his attacks so weak...?' Keira muttered inwardly in a confusion until slowly a realization began to come to her.
