Road Extension (ロード・エクステンション) is a Release Type Magic that alters the electrons between the tires of a vehicle and the road, using the concept of Coulomb's Law to devour any acceleration, in order to reduce the friction to nearly zero. The calculations necessary to actually realize this Magic Sequence are said to be absolutely terrifying. [1]
