Speed Up is a a magic spell that increases the speed of the user or someone targeted by the user by a certain amount.
The user uses magic energy to increase the movement speed of either themselves, other people, or even inanimate objects. Depending on how skilled the user is in magic they can increase the speed of the target by a certain percentage (The highest so far being Vesper with 125% speed increase). The user is then surrounded in a light blue aura until the spell wears off (although the color varies depending on the user).
Users can also increase their speed with the help of technology or charging their energy.
