High Speed, aka God's Leg, is a Caster Magic involving the use of one's speed.
Description[]
High Speed is a type of Caster Magic that allows the caster to move at extremely high speeds. However, despite the Magic's speed-increasing properties, it apparently cannot defend against any Magic used to intentionally slow the caster down.
When used in combat, High Speed can be very efficient; the increase in speed makes it so that melee attacks that would normally be considered weak become very effective.
