Sistermon Ciel

Sistermon Ciel appeared in 2017 video game called Digimon Story: Cyber Sleuth - Hacker's Memory. Sistermon Ciel is a Puppet Digimon. A Digimon wearing a veil modeled 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").

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.
