Irina Shidou is Issei Hyoudou's childhood friend and one of the main female protagonists. Initially an exorcist of the Protestant Church, she was later reincarnated as an Angel, becoming the "Ace of Spades" in Archangel Michael's peerage of Brave Saints.

Despite her devout Christian faith, Irina harbors romantic feelings for Issei and becomes one of his many fiancées. She struggles with impure thoughts that cause her Angel wings to flicker black, risking falling from grace as a Fallen Angel.

History

Irina came from a lineage related to the Church, with her father being a pastor and exorcist. As a child, she was very close friends with Issei Hyoudou, and they even shared his first kiss while he was asleep.

At age 14, Irina was made an artificial Holy Sword wielder and granted the Excalibur Mimic. She partnered with Xenovia Quarta on missions like slaying the Manthar Vampire.

After learning that God from the Bible was dead, Irina's strong faith transferred over to the current "God," Archangel Michael, who reincarnated her as an Angel and his "Ace."
