With that mental change, he became a source that spewed forth a unique power into the
real world.

Accelerator put his hands on Last Order's small shoulders, lightly pushed, and floated
up into the sky due to the recoil like an astronaut in zero gravity.

Last Order's small hands stretched up into the sky toward Accelerator.

But she could not reach him.

Accelerator was already floating a few meters up.

Convinced that he had done the right thing, Accelerator flapped his white wings. His
one-hundred-meter wings used more than just the power of the wind. They also
converted some more unknown energy into lift. He emitted no force down at the earth,
but he still shot up like a bullet.

In an instant, Accelerator reached a point three thousand meters up and scattered the
thick clouds that were hanging in the sky.
