Cosmina

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

Appearance
Cosmina is a young woman with bob-style haircut and bunny ears accessory on her head. She wore 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, showing no remorse for her actions.

She is severely perverted as when Enshin kicked her for not "sharing enemies to kill", she had no problem with him seeing her underwear while telling him she'll take care of him later and was shown multiple times to not care the slightest if her underwear shows. During the Incident of the Umatora Theater, she took part in the mass rape but only doing so to "pretty boys" showing she's not only as twisted as her comrades but quite shallow to boot.

Bio
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 of fire, killing her entire family. Cosmina was the only survivor, however, she fell into insanity as the result.

Cosmina was then seen when the Wild Hunt were introduced to Honest. She displayed her Teigu's power, producing 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 visited the Wild Hunt HQ, she greeted him and flirted with him. After Run lured out Champ with a simple but effective lie, Cosmina and Enshin headed out to follow them as Enshin grew suspicious.

The two were intercepted by Kurome and her corpse puppets; Cosmina managed to destroy two Danger Beast puppets using her Teigu's maximum power. After Champ's attack leaving Run fatally injured, Cosmina attempted to rape him; this led to her losing sight of the battle which resulted in her being shot by Mine.

Some time later she was picked up by Dorothea who found her close to death, and in order for her to heal 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.

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.
