Witch Mask was the leader of a scheme for the Black Cross Army to capture a freeze beam developed by EAGLE that was being guarded by Shinmei and Ooiwa. She and a squad of Zolders capture the beam and kill various EAGLE soldiers while eluding the two Gorenger. When Kirenger tries to pursue her, she ends up capturing him while Shinmei's initial strategy to save both ends up in failure forcing a retreat by Variblune.
Kaijo ends up coming to Ooiwa's rescue, disguising himself as a Zolder and making Ooiwa make himself look like Witch Mask in order to confuse a squad of Zolders into which was real. While it works, she ends up capturing both until Shinmei returns, this time with Peggy and Kenji, using the blue smoke of Variblune to escape to elude various Black Cross weapons to allow for them to wear them down before Aorenger recaptures the freeze ray. The five then finally finish Witch Mask off with Gorenger Storm.
- Witch Mask is the first female villain in Sentai history.
