Orochi is a former Third Generation pyrokinetic within the Knights of the Purple Smoke.

Orochi was a woman with short light hair, with a long fringe that covers the left side of her face. She had dark eyes and lighter pupils along with long eyelashes. She wore the uniform of the Knights of Purple Smoke, which includes a cloak branded with the Cross of the Holy Sol on the front and back that also hides her body. Under the cloak is a tight tabard that shows her cleavage and is split up the thighs showing a curvy figure with huge breasts and wide hips. Both her dress and arm guards bare this symbol as well.

Orochi was an extremely direct person, speaking mostly in short sentences devoid of emotion or expressing simple confidence in her abilities. While she did express surprise, she was an extremely controlled and calm individual who acted efficiently. She is also sarcastic and condescending, belittling the weakness of her enemies while praising her own skills.

Using her Ignition Ability, Medusa Whip, Orochi could manipulate a whip made of fire using a handle and fire off her whip at incredible speed. She was able to turn the whip at will, morphing the wipe's tail into a blunt and rigid state or generating at least 8 tails for the whip, similar to a Cat o' nine tails. By rotating the tails quickly, she could use her flames like a shield capable of blocking bullets. In turns of offence, Orochi could use her Medusa Whip at blistering speeds. Her lashes were capable of cutting through a human being and a fire-resist Fire Force uniform with ease while possessing tremendous force behind each lash. When faced with a Third Generation pyrokinetic's natural resistance to flames, her whip was only able to pierce their skin by applying continuous pressure.
