She has the attitude of a proper young lady, she is strict and determine to adhere the rules of the school.

Whenever she gets flustered or excited she tends to revert to speaking French.

Abilities and Powers[]

Master Swordswoman: Mary has an extremely high level of skill in western style fencing, accurately piercing central nerves with her rapier. According to Tsukiyo, Mary's swordsmanship is a mixture of Japanese and Western sword techniques, combining Jigen-ryū with fencing. Thus Mary can perform extremely swift and precise sword thrusts consecutively, allowing her to cut Nomura's several times as he could barely keep up.

  • Flick: Mary diverts her thrust, striking past the opponent's defences and delivering a small cut.
  • Redoublement: Mary flails her sword around, making the path of her attack unpredictable.
  • Touche par Touche: Mary delivers a thrust downwards.
  • Touche par Dessous: Mary delivers a thrust upwards.

Enhanced Speed: Mary is extremely quick in launching her sword thrusts with incredible swiftness. With her exceptional footwork, Mary could easily keep up with Nomura and take down the Hanasaka Musketeers instantly.
