water wings fight

Saten was guiding the group of people by gesturing, but she suddenly froze. Uiharu
looked over and noticed that a battle was occurring within the city, too.
The scenery was a mess. Buildings had collapsed and tilted and crushed rollercoaster
tracks were blocking the path. A large Ferris wheel collapsed and crushed a few
buildings as if it had been pushed by a giant.
Some people were fighting amongst that.
One of them seemed to be Misaka Mikoto. Uiharu did not know how, but she was flying
around using six glowing wings. The other was one of the flying fish. One seemed to be
trying to destroy a one-hundred-meter aircraft and the other seemed to be trying to
defend it.
“Xochitl...?” Saten muttered upon seeing that flying fish.
“Eh?”
“No, don’t fight that person, Xochitl!!”
The next thing Uiharu knew, Saten was already running.
The girl was wearing only a swimsuit, but she was running toward that battlefield in
which small missiles and Railgun blasts were flying back and forth. She was charging
into a site of intense fighting where stray shots were destroying empty buildings or
blowing away roads.
