Irene has a short black hair and piercing green eyes. She is also shown wearing a white fitted blouse with black accents and a black pencil skirt.
Irene is a true lady at heart and a model of sophistication. But she can become easily jealous of Mika. This is due to Mika's and Erik's relationship with each other. Erik declares to Irene, that even though Mika is his princess, she is his queen and his love. While Irene knows that Erik will always stay loyal to her, she can't help but be a little jealous from time to time.
Not much is known about Irene. In Seduce Me 2, it was stated that Irene was a demon. Mika is convinced that Irene is a succubus, but Irene has never confirmed this. She respects humans and made her way to the top of the financial hierarchy the "old fashioned way".
