Lady

Mary Ann Arkham, also known as Lady, is the deuteragonist of Netflix's 2025 animated action fantasy series Devil May Cry, based on the Japanese video game franchise of the same name.

She is the Lieutenant Devil Hunter of DARKCOM, who has a strong hatred towards devils due to her tragic past of her father developing an obsession on demonic power, which led to the death of her mother.

Lady is an attractive young adult woman. Due to having heterochromia, she has one eye of green color and one of red color. Throughout her life, she mostly kept her hair short.

Since as a child, Lady has a strong sense of justice and desire to save the world from demons. While she believes in Baines despite his agenda, she has many doubts about how he goes about his plan. Her hatred of demons runs deep due to her father becoming one out of fear to protect his family and killing Kalina Ann as a result of his madness.

She sees demons as purely destructive, even willing to kill their own, though she's not oblivious to Sparda and his siding with humanity.
