Bullet Time

Bullet Time is a Caster Type magic, generally used by those who use Guns Magic.

Overview
The user can freeze, or slow down his perception of time, allowing him to react to bullets coming his way. However, even though everyone else seems to be moving slower, or is stationary as well, the user's body matches their speed. The user can also remove their consciousness from their body in Bullet Time and take note of their surroundings before reacting.

Trivia
Bullet Time is based off of the game mechanic where everything surrounding the player can be voluntarily slowed down.
