  • Calamity Mary (Drama CD)


As a human, Naoko Yamamoto has medium-length messy brown hair. She wears a purple blouse with black patterns on it, and long black skirt.

Magical Girl

As a Magical Girl, Calamity Mary has long blonde hair, golden eyes, and a beauty mark under her left eye. She wears large silver earrings, circular in shape and with jagged edges.

She wears a cowboy hat and has a Wild West-style attire as her outfit. She wears a light-brown top, with white and black trim around the edges. She also has brown sleeves, with many strips of fabric that hang down. The tops of the sleeves are decorated with the same trim. She also wears two black ribbons around her neck.

She has black knee-high boots and a holster on her left thigh.


She first comes off as relaxed, free-spirited, and villainous. However, she has a more sadistic, insane side, as shown when she attempted to murder Hardgore Alice brutally after the latter killed Magicaloid 44.

Calamity Mary frequently drinks a lot, and curses more than the other magical girls in Unmarked.


To magically enhance any weapon she uses

Calamity Mary's magic allows her to increase the capabilities of any weapon. It isn't limited to increasing its power and strength: she can also increase a variety of other attributes, such as its range, firing rate, and durability.

A "weapon" is defined as anything Mary can use offensively. Because of this, things that aren't originally weapons, such as gasoline or rope can also be enhanced by Mary's magic.

Her magic is permanent; it will not cancel if the weapon is no longer in Mary's possession or after her death.

Special Item(s)

  1. 4-Dimensional Bag (Former): Magical item. Not limited to objects, as living things can be packed into it too. It's more of a bag rather than a pocket.
  2. Magical Weapons: Calamity Mary have a collection of firearms that she enhanced with her magic.
