Irene is a tall, voluptuous woman with thickly braided, bow-adorned, scarlet hair. Her two front braids have two golden ornaments near the upper sections; she also wears two U-shaped earrings (one on each ear), and wears red lipstick. For clothing, Irene dons a risqué version of the typical witch's garb. Her black top has a diamond-shaped opening, exposing a portion of her breasts, and a heart-shaped pattern around the borders. It extends down to the naval of her stomach where it meets a large angular scar, is draped over by a dark-colored cape with a light-colored inside and two medallion gold-like ornaments, and is held together by a golden chain. Not left bare, too, her neck is decorated by other small cloth-based accessories, including a wide bow. Additionally, Irene wears an elongated black loincloth with the symbol of the Alvarez Empire emblazoned on its front, having white borders on its edges and being connected to another cloth piece with the very same heart-shaped design. She also wears black thigh-high boots with heels that have a white-colored border near the top and gloves of the same color and design, only having claw-like extensions. Her black witch's hat is much larger than her head and possesses dreadlock designs with white bandaging near its ends. It also has a fur lining near its edges. Irene has shown to be very knowledgeable, showcasing herself as a historian when revisiting a folktale of her birthplace, seemingly enjoying the counterbalance of a "wonderful story" of the two angels of Zonia. She's shown to have a humorous side to her, as seen when she wanted to see Juliet and Heine do battle, only to later say it was a joke.
