I just stood where I was and whispered, "Shadow Ball." I put both hands behind my back, forming the shadow ball. I saw Kyoudai's fangs and claws enlarge, but they didn't scare me. I didn't even flinch.
"I don't plan on using much energy either, as I intended." I slid away into the shadows of the trees as I talked, still holding the shadow ball in hand.
Setting myself in the darkness, I forced the shadow ball around the arch of the trees and saw that it came out the other end and circled around to hit Kyoudai in the back, without him seeing at all. Direct hit. He lundged forward, falling to his face. I could see a more angered face on him as he lifted up his head. I waited, moving silently in the trees.
