Impact Cannon (インパクトキャノン Inpakuto Kyanon) is a bombardment attack used in the cross or even zero range.[2] Speedy and without much charging, the mana cannonball is fired like a shooting spell instead of a lasting beam.

The spell is possessed by Nanoha Takamachi, who has learnt this spell for teaching Modern Belkan system practitioners in the Administrative Bureau. In its only anime appearance in StrikerS, it is obtained and cast by Heiliger Kaiser Vivio instead.


The spell name may be a reference to Space Noah-class battleship's main armament of the same name or Huckebein Mk-II's G-Impact Cannon from Super Robot Wars series.

Notable usesEdit


  1. ^ There is no canon source for the magic system and spell type of Vivio's version. It is deemed as under Midchilda system for simplification, as English spell name is retained from the original spell and Vivio's magic system is officially referred as Belka and Midchilda hybrid in ViVid.
