Irina Shidou

Irina Shidou (also romanized as Shidō Irina) is one of the main female characters and heroines in High School DxD.

She is Issei Hyoudou's childhood friend from when they were young. Irina is a cheerful, upbeat, goofy, and enthusiastic girl with a very devout Christian faith—she remains deeply religious and follows God's teachings even after learning of His death in the story's lore. She later becomes a reincarnated Angel serving under Archangel Michael (as his "Ace" in the Brave Saints system) and one of Issei's fiancées.

She transfers to Kuoh Academy as a third-year student and lives in the Hyoudou residence. Irina is skilled with holy swords (originally wielding Excalibur Mimic, a shapeshifting holy sword) and later uses light-based weapons like light swords, bows, and arrows as an Angel.

She has long chestnut hair usually styled in twintails with blue scrunchies, violet eyes, and a bright, energetic personality that's often cooperative and open-minded toward others (despite her strong faith).
