It is a shockwave attack that looks like the palm variation of Unchain Knuckle, and is classified by the DSAA as a "body-strengthening strike" (身体強化打撃 shintai kyōka dageki), although it is in substance a cross-range shooting attack.
In its first use in ViVid (ch.15), a "(temp)" (（仮） (kakkokari)) is attached to the spell name and is not deleted even in the re-published bound volume, indicating Einhard might not have decided the spell name as she has just invented this spell after learning Unchain Knuckle. The spell name is eventually confirmed in ViVid (ch.25).
- Near the end of the mock battle in ViVid (ch.15) / ViVid anime (ep.06), Einhard uses it against Vivio Takamachi who is going to attack Teana Lanster.
- Einhard uses this attack as finish blow to knock out her opponent in her first Intermiddle Elite Class match.
- Einhard casts it against Corona Timil in their Intermiddle match.
