Sistermon Ciel is a Puppet Digimon. A Digimon wearing a veil modelled after a mouse, it is Sistermon Blanc's elder sister as well as the twin sister of Sistermon Noir. Instead of travelling together with Noir and Blanc, it roams around the Digital World investigating unusual phenomena and reports its findings to Gankoomon. Despite its gentle personality, it is strong-willed and popular with the Digimon residing in the places it visits. While it is friendly and leads a peaceful life by day, by night it turns into an assassin who hunts down any troublemakers it receives word of. It has a cherished sword named Shirotsume-Ichimonji (白詰一文字? lit. "White Clover Line").[2]


  • Shirotsume Ichimonji-giri (白詰一文字切り? lit. "White Clover Horizontal Slash"): Cuts down the enemy without making a sound.
  • Byakusai (白殺? lit. "White Murder"): Rapid-throws the two knives it hides within its sleeves.
  • Tohhō (突蜂? lit. "Piercing Wasp"): Lures the enemy in until they let their guard down, then stabs them in their vitals at close range using the knives planted on its feet.
  • Silent Bullet[3]: Unleashes the T in a silent but deadly attack.
  • Fury Fire[4]: Unleashes the T in a rapid fire straight line.
  • Tekken Seisai (鉄拳制裁? lit. "Striking With Fists"): Strikes with all its strength at anyone and everyone who talks back to it.


Sistermon Ciel is similar in design to Sistermon Noir, but has longer, smoother hair, with its left bang covering its eye, and it carries a white-and-gold sword, which has a black sheath. The eyes on Ciel's Klobuk are animate and change based on Ciel's emotions, giving Ciel two sets of eyes.

In Digimon Story: Cyber Sleuth - Hacker's Memory, it has Sistermon Noir's hairstyle and T guns, but its klobuk is sky-blue with mouse ears instead of black with cat ears, it has navy blue hair in place of Noel's silver hair, and its habit is white instead of black. However, its dot sprite retains Noir's cat ears.


Sistermon Ciel (シスタモン シエル)

Official name given by the Digimon Reference Book and used in the franchise.

  • En: Sister.
  • Fr: Ciel (lit. "sky"). From the color sky blue.


Sistermon Ciel was created as a redesign of Sistermon Noir due to religious sensitivities, designed with a sky-blue and white uniform instead of Noir's black to distinguish it from the traditional uniform of a catholic nun, but is considered a separate species.[5]
