Akumi has long, straight black hair that ends at her waist. Her left eye is purple while her right eye is blood red. She has pale and fair skin, often called "perfect". Akumi has an hourglass figure and large chest. However, she has a long silver scar that goes around her neck entirely from her childhood, as she tried to hang herself.
Akumi enjoys solitude and often spends her time alone. She rarely smiles or laughs, but is more likely to behave friendly to someone she's come to know. She'll also speak in a sweeter tone when she comes to know you. As a victim of abusive parents, Akumi is remarkably fragile, and has difficulty trusting people. She's very quiet, and is much more of a listener than a speaker. She has a high tolerance for annoying people.
