Airi

Airi is a wraith summoned by The Swamp Witch, to kill her enemies in the Queen's Blade Tournament. Airi is totally devoted to her mistress, the Swamp Witch, much more so than Menace or Melona. She can suck away the life energy of her enemies simply by touching them.

History
Airi serves the Marshland Witch, she who controls the undead and apparitions from the Netherworld and plans to rule over the Continent. She's a spirit summoned from the Netherworld and was enchanted with an obedience spell by the witch. Even if she's being forced to work under her, Airi performs her duties admirably and with no complaints.

Although she's a spirit, Airi's body has substance. Her clothes don't, and they're just an image projected by her, that seem real in the eyes of normal people. Without sucking energy from living beings, Airi can't stay in the earthly plane. She manages to suck energy by touching directly the bodies of her victims, and she seems to enjoy it more when the victim is frightened.

To rule over the Continent as soon as possible, the witch sends an elite troop to enter Queen's Blade. Airi, liking to suck energy from beautiful women, goes to serve her master all too willingly.
