Marvelous raised a hand to catch the gun, while at the same time chucking his saber - Shinken Red Key still inserted into it - back at her. Her caught the firearm, and raised it.

He cocked back the hammer.

The collar was still there, but starting to unclasp. Futo was raising something to try and keep her in place.

For many others trying to do this and not KILL someone would seem utterly insane. In truth, it probably was. Many of those others might not be able to shoot an incoming bullet cleanly out of the air.

Marvelous could.

So, he took some amount of faith that the other distractions would do their job, aimed for the collar... and took his shot, one round bullet erupting from the gun's barrel.
