The intrinsic protective layer that Donut's Laundry Day violently strips from Huanxin Jinx.
Soul Armor was the first thing Huanxin Jinx lost. As she began to say "You dare?", bubbles appeared behind her and Donut's Laundry Day violently ripped the soul armor off the goddess-sponsoring CEO, leaving her wearing nothing but a long white undershirt and dropping her into the Circle of Power.
With the soul armor gone she was left with only her technological shields, which Donut destroyed outright with Claw, and with a teleport ring that the circle rendered inert.
An unseen protective layer whose removal leaves the wearer in only a plain white undershirt.
The defensive layer whose removal is the first step in killing a god-tier being.
