dark matter clash

“Hah. You don’t get it, do you?” said Accelerator quietly, tossing his cane to the side.
“This is great. I’ll show you how villains come in many colors.”
An explosion rang out.
Accelerator and Kakine Teitoku clashed head-on. The aftermath shock wave blazed
through their surroundings equally, mowing people down, shattering glass to
smithereens. In every direction, clamors broke out—but neither paid attention.
Their clash had shown clear results.
Accelerator’s attack had sent Kakine Teitoku flying back. He shot into a café on the road,
and a series of cracking and breaking noises followed as he tore through furniture.
Accelerator’s expression, however, was nothing if not displeased. The feeling of his
punch having purposely gone awry remained in his palm.
“You control the vectors here and now,” said the voice from inside the shop, which
looked like it had been bombed by terrorists. “I thought I could manage by using so
much mass you didn’t have enough vectors to move it, but I guess that won’t work. I
can’t do anything if you’re controlling my own vectors, too.”
Unharmed.

When Kakine came out of the store, he was wrapped in a white cocoon. No, not a -
cocoon—they were wings, spread on their own. Six angelic wings flapped slowly behind
him.
