Background
Carbuncle is an Elemental that obtained a name and a "body" through unknown circumstances. She was incarnated into a pair of enchanted silver earrings, removing her freedom entirely. After passing hands from owner to owner, she was unexpectedly set with a pair of particular magical gems. The power of the gems granted her enough power to temporarily detach her spiritual body from the earrings and roam the world freely as a magical corpus. From here, she hatched a scheme that involved using her newfound power to "cut" the stress from humans and crystalize it into new magical gems, but, as her form was only temporary, she lacked the power to do so herself. In order to enact out her plan, she needed to be "worn" by a powerful individual, allowing them to use her power in order to produce the stress crystals.

While posing as the merchant Tiahier (チアヒア), she managed to stumble upon and trick Chloe Aubert and Alice Rondo into wearing her. While she was being worn, her power physically manifested as a special armor and sword, resembling something worn by stereotypical "magical girls". By using the power of the stress crystals, she was able to overwhelm the emotions of humans, sending them on a stress-induced rampage. Chloe and Alice, in kind, would defeat the rampaging humans by using Carbuncle in sword form to "cut" away their stress. After their stress was "cut" it would crystalize into a new stress crystal and the cycle would start anew.

While in the process of collecting the stress crystals, she was eventually found out and defeated by Rimuru Tempest. After hearing her story, Rimuru decided to incarnate her into a "Golem" of his creation in exchange for taking ownership of all the stress crystals that she'd gathered.
