Cefiro

As the commanding officer of the Demon King Army's Seventh Legion, Cefiro serves as Ike's direct superior within the military structure. Among all demon-kind, she stands as one of the rare few who are privy to the secret of Ike's human identity, and she has quietly aided him in concealing that truth over an extended period. While she carries herself with a seductive charm and takes evident pleasure in teasing Ike, she transforms into his most dependable ally when military matters or the safeguarding of secrets are at stake—demonstrating exceptional mastery in both magic and alchemy.
