Purple Lightning Flash (紫電一閃 Shiden Issen) is Signum's signature charged attack with Laevatein in Schwertform that covers the sword blade with flames to increase its power.

In StrikerS, Signum teaches the spell to Erio Mondial. It is going to be a similar lightning slashing attack with Strada, although it is applied by Erio differently in its first appearance.


Shiden Issen can also be translated as "swordflash", since shiden is also a word to describe sharp lights on blades.

Notable usesEdit

  • In the A's manga, Signum is able to kill a summoned dragon with it in one hit.
  • In StrikerS (ep.24), Erio uses his Purple Lightning Flash by concentrating electrical energy in his fist and punching Garyu to deliver an electric blast. The spell is here applied differently because Strada is being tightly held by Garyu.
  • At the TSAB Midchilda Ground Headquarters, Signum uses Purple Lightning Flash to end the life of Zest Grangeitz.


  • Purple Lightning Flash Whisper (紫電一閃・一颯 Shiden Issen Ibuki) is the cross-range block attack used by Signum in The Battle of Aces,[1] being a lite version of the spell. This attack can only be performed after blocking an incoming attack successfully with a barrier spell in the game.
  • Luminous Fang (煌牙 Kōga) is a fiery sword attack cast by Signum during her battle against Nanoha Takamachi in the special chapter of the StrikerS manga. It appears to be a more powerful or mobilized version of Purple Lighting Flash, but is not further depicted nor described in details. It may also have a longer spell name, as the close-up scene is ended after Signum casting "Kōga" and Nanoha casting "Divine". A relevant name adopted in INNOCENT is Purple Flame Luminous Fang (紫炎煌牙 Shien Kōga).
