Glitch

As Levi clenched his fist, the blue of his body routed to that area, releasing a soft puff of blue smoke. That blue smoke was the starting point for the transition his fist, and then his arm, was about to take. 

With eyes set on Sebastian, Levi decided to carry himself and his unwilling, transfigured skin to victory. He started taking quick, short steps, accelerating and speeding up with every second until he was sprinting at his topmost speed without powering himself. Then, he decided to boost himself off the ground. A blast of blue erupted from his limbs and propelled him off the ground and into the sky. For a moment, he soared effortlessly, but then, like a faulty rocket, his body glitched, causing him to lose power for a split millisecond. It sent a jolt of fear through him. However, almost immediately, the energy reignited with a whirr of blue, stabilizing his flight as if nothing had gone wrong.
