Cosmina

Cosmina was previously one of the members of the Empire's Secret Police, Wild Hunt. She is a singer fully equipped with a microphone, which actually is her Teigu.

Appearance
Cosmina is a young woman with bob-style haircut and bunny ears accessory on her head. She wears a minidress, a collar and matching wrist bands, boots and a pair of glasses.

Personality
Cosmina seems to love putting on a show for her opponents while killing them, singing and striking stage-like poses with a cheerful smile and showing no remorse for her actions.

She is also severely perverted. When Enshin kicks her for not "sharing enemies to kill," she had no problem flaunting her underwear while telling him she'll take care of him later; this happens multiple times, while Cosmina seems to enjoy it if her underwear shows. During the Incident of the Umatora Theater, she took part in the mass rape.

History
Some time before the start of the series, Cosmina lived in the Western Country and, due to her voice that could manipulate people, was branded as a witch. This led to her house being set on fire, killing her entire family. Cosmina was the only survivor, the loss and trauma driving her into insanity.

Cosmina was then seen again when the Wild Hunt was introduced to Honest. She displayed her Teigu's power, which produced devastating, bone-shattering sound waves. During the investigation at the Umatora Theater, Cosmina gladly took part in mass rape, taking all "pretty boys." She was present during all other affairs of her group.

Later, as Run visits the Wild Hunt HQ, she greets and flirts with him; however, after Run lures out Champ with the intent to avenge his students' death, Cosmina and Enshin follow them in suspicion.

The two are intercepted by Kurome and her corpse puppets; Cosmina manages to destroy two Danger Beast puppets using her Teigu's maximum power. After Champ's attack leaves Run fatally injured, Cosmina attempts to rape him; however, this distraction caused her to be shot by Mine.

Close to death, she was picked up by Dorothea sometime later, and was put in a cryogenic tube at the newly established workshop in the Capital. However, due to being left in a near-death state for a prolonged time, Cosmina apparently received permanent brain damage and remains incapacitated.

Equipment and Skills
Cosmina used the Teigu, Heavy Pressure, which enabled her to unleash devastating, ultra-sonic sound waves, pulverizing and destroying the bones of her victims.

According to Syura, her voice was capable of manipulating people; she appears to possess great vitality which greatly surprised Dorothea, a seasoned alchemist.
