"Les Soldats" ("The Soldiers" in French) is a mysterious organization in "Noir". According to Altena, a thousand years ago, a group of people who had survived a bloody war that cost numerous lives, formed a group called "Les Soldats" to protect the weak and take revenge on the world. When Kirika travels to a Soldats' village, she finds out that during the late tenth century, "Les Soldats" has taken place in every social part of humankind. For example, Soldats were witnessed at the birth of the Greone's mafia family, which was created 200 years ago from the time the series began. Near the end of the series, Altena states that "Les Soldats" have been consumed by the very greed they once swore to undo, and thus had become like the world itself.
