Airi is a ghost girl bound to the Swamp Witch's service. Summoned into human form as part of the witch's quest for power, she serves without question—willing or otherwise. She's typically dressed in a maid outfit and carries a scythe, the combo giving her an appropriately unsettling appearance.
Her main job is assassination. What makes her genuinely dangerous is her ability to drain the life force of anyone she touches, which is about as straightforward and lethal as it sounds. She doesn't need the scythe to kill; the touch is enough.
