— Calamity Mary to Ripple

Calamity Mary (カラミティ・メアリ), also known by her real name Naoko Yamamoto (山元奈緒子), is one of the main antagonists of Magical Girl Raising Project.

Calamity Mary is a Magical Girl hired by the N-City's criminal underground "Kannawa Association". She gains rewards by "helping" them.

Fav LN.pngCalamity Mary.jpgFal.pngSpoiler(s) Below!
In Black, she is one of the few homunculi that attacks the students of Umemizaki Middle School. Shadow Calamity Mary acts as a threat to Group 2 during their second mock battle.



As a human, Naoko Yamamoto has medium-length messy brown hair. She wears a purple blouse with black patterns on it and a 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 comes off as relaxed, free-spirited, and villainous. She wants people to fear her and feels humiliated when someone tries to defy her. She will then do whatever it takes to kill them or make them bow down before her. She also has a more sadistic side, as shown when she attempts to brutally murder Hardgore Alice after the latter kills Magicaloid 44.

Calamity Mary is also an alcoholic and frequently drinks. She curses more than the other Magical Girls in Unmarked (Arc 1).


Can power up the weapons she wields.

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)[]

  • 4-Dimensional Bag (Former): A magical bag. Not limited to objects, as living things can be packed into it too. It's more of a bag rather than a pocket.
  • Calamity Mary's Arsenal: Calamity Mary has an arsenal of firearms that she enhanced with her magic.

Hardgore Alice[]

After Calamity Mary finds out Hardgore Alice killed Magicaloid, she proceeded to ambush her in order to kill her as a way of revenge for Magicaloid 44. Calamity Mary was surprised of Alice's magic protecting her from death. Mary tried numerous ways to kill her, like stabbing or shooting her, but all of them ended in failure. Calamity Mary even came to the point of trying to burn Alice alive.

Calamity Mary rages and does her best to stop Alice from regenerating. She manages to throw her body to a lake and claims that nobody has embarrassed her as much as Alice did. Calamity Mary congratulates herself for killing her strongest opponent and celebrates, but it didn't last too long since she found out Alice survived the attack. Calamity Mary falls into despair and decides to leave Alice alone.
