A.C.S Driver (A.C.Sドライバー Ē Shī Esu Doraibā) is Nanoha Takamachi's spell to expand fully the Strike Flame under Raising Heart Exelion's Exceed Mode, and perform acceleration-charge-strike attack with the help of the Accelerate Charge System. It is classified as an "energy blade generation + flight support strengthening" spell.

With command phrase "Charge!", Raising Heart's end tip releases a stream of mana to boost Nanoha's flying speed for the charge attack.[1] A combination of the heavy armor, acceleration charge and the offensive field generated by the Strike Flame, A.C.S Driver can destroy the targets around in a flight, without any physical contact.


The proper full name of the spell will be Accelerate Charge System Driver.

Notable usesEdit

In StrikerS (ep.22), Nanoha casts A.C.S Driver to destroy streams of Gadget Drones in The Saint's Cradle.[2]
