Mez was a short girl with a petite build. Her hair was blonde and styled in pigtails decorated with horseshoes that also served as weights. She had green eyes and her skin was considerably tanned. She wore long leggings and a shirt, which she left open, displaying a bikini/swimsuit top. Like her fellow Rakshasa Demons, she had armored plating on her forearms.
Mez seemed to be very easygoing, even when in combat. She casually seemed impressed by the death of her comrade and disappointed by the seemingly easy death of Lubbock. Her personality does not seem to change much even when her own life is in danger, even going so far as to respond to Lubbock's flirting. She also did not seem scared about dying or killing others, noting that as assassins it came with the territory.
She has similar abilities to the other Rakshasa demons. She can freely control her body. She has been show to be able to do the following:
- Extending her arms;
- Extending her nails;
- Releasing a lot of sweat.
Aside from the ability to control her body, she has also been shown to be really fast. Her speed increased even more when she detached the horseshoes from her hair.
She was also able to sense that Lubbock was suspicious, despite Lubbock being one of the best actors in Night Raid.
