Iron Wrists (鉄腕 Tetsuwan) is presumably a defensive spell of Sieglinde Eremiah in ViVid, as it is referred to as her skill instead of Device in the DSAA entry information, despite the details of her Device is yet to be revealed.
It generates a pair of sleeved-glove-like defensive armament, covering from her upper arms to finger tips, with iron armors at her knuckles and wrists. Apparently it also strengthens her attacks, and perhaps enables her to use the ultimate skills of Black Eremiah. The incantation is "Iron Wrists Release!"
- It is first seen in ViVid (ch.41) during Sieglinde's Intermiddle match against Einhard Stratos.
- In ViVid (ch.48), Sieglinde casts Iron Wrists and Geistnagel to break through Fabia Crozelg's capturing bottle.
- When Eremiah's Memoirs is being read in ViVid (ch.53), it is depicted that Wilfred Eremiah released Iron Wrists during her spar with Claus Ingvalt.
