Endorsi is a fairly human-looking girl with orange-yellow eyes. She is said to be very pretty, as she is one of Zahard's Princesses, and has short brown hair. Her only non-human feature would be the skin-colored horn on the right side of her forehead.

She is haughty yet friendly, with a confident exterior masking a longing for the affection she lacked from her late foster parents. Despite her intelligence, her emotions often lead to impulsive actions, revealing a complex and vulnerable side.
