Kalawarna

Kalawarna (also spelled Kalawarner or Karawāna in Japanese) is a minor antagonist in the early part of High School DxD.

She is a Fallen Angel who allies herself with Raynare in the plot to steal Asia Argento's Sacred Gear. She appears as one of Raynare's subordinates alongside Dohnaseek and Mittelt.

Kalawarna is depicted as a tall, buxom woman with long navy blue hair (covering one eye), brown eyes, and a revealing outfit consisting of a maroon trenchcoat-like top (open at the chest), miniskirt, and heels.

In personality, she comes across as arrogant, sadistic, no-nonsense, and cruel, looking down on her opponents with little mercy. She gets killed relatively early in the story by Rias Gremory during the confrontation in Kuoh Town.

She's a fairly short-lived side character mainly from season 1 / volume 1-2 of the series.
