Aero Hand

Mikoto facepalmed at the Japanese-style black-haired girl’s behavior.

Kongou Mitsuko’s Aero Hand let her create air ejection points on any object she touched, so she could be a lot of trouble if she played her cards right. She could apparently launch a broadcast tower into the stratosphere, so she had Mikoto’s Railgun beat when it came to simple attack range. Since the School Garden was currently an isolated space located high in the sky, Kongou could start wearing her down with projectile attacks and finally knock her over the edge into the 5000m abyss of the sky.

On the other hand, Kongou’s power was limited to that side of things.
