Testing out some things...

The air around them became lighter. Naku could feel herself staying in the air without using her wings. She had an advantage here. She could move at will, he probably couldn't. Her wings pushed her to the ground. "Simple!" She kicked her legs off the ground, speeding herself towards Alchem, her bladed fist held out.

Alchem opened a tear in space in front of him. He positioned it so Naku would fly in. He made another behind him, where Naku would come out.

Her heightened sense of observation noticed the rip in space. She moved her wings to stop herself, but the lack of gravity made it a little hard. She flew through the portal, ending up behind Alchem. She turned her body, using her wings, angrily. She stood there, waiting for him to move towards her instead.

But alchem instead walked into the portal in front of him. Instead of coming out of the other one, he appeared out of a third portal behind Naku.
