Turning the body hard as steel, the power of any physical attack will become damage to the attacker. It is an offensive defence (攻性防御 kōsei bōgyo), as commented by Nove Nakajima.
- In ViVid (ch.29) / ViVid anime (ep.11), Einhard casts it during her Intermiddle match against Corona Timil. It successfully makes Corona get hurt from her own Revolver Cannon and Revolver Spike.
- In The Gears of Destiny, Fang Mountain is also referred to by Einhard when she successfully performs an "EX-Guard" (i.e. just-in-time defense), although the spell is actually the shield-type Panzerschild.
