Overdrive (ability)

An Overdrive is a Magic Formula which helps reduce the burden on the body of its user when said user begins the usage of massive abilities.

Kagura Mutsuki described it as being a burden itself, as well as a dangerous asset, for in the case that one was incapable of properly controlling it, the user’s soul could even be sucked into the Boundary. Through the utilization of the Blue Grimoire, it is possible to effectively reduce the risk.
