"The Siestas are bunny-girl servants summoned by Beatrice. It is said that there is no escape from the Siestas' attacks, and they can even locate and bring back a corpse. They have red eyes, bunny ears, and elaborate military-styled outfits. It is hinted that they are connected to Maria's three (originally four) rabbit toys."
- The Siesta Sisters are revealed to be a large force in Dawn of the Golden Witch. Siesta 410 names two others, Siesta 127 and Siesta 20. Siesta 127 is said to be able to pulverize a human target at 2 kilometers, while Siesta 20 has a fire rate of 6,000 rounds per minute. Since all the other Siesta sisters are named after guns, Siesta 127 most likely references to the 5-inch deck gun which has a 127mm wide shell and a range of well over 2 km. Siesta 20 likely references to the M61 Vulcan Gatling Gun which fires a 20mm round and also has a fire rate of 6,000 rounds per minute.
- Even though their firing codes are written in Greek, the banners they have on their left arm resemble the flag for Iceland.
- Their alternately-spelled name of Chiester is a corruption of the word Winchester, a series of guns that Kinzo Ushiromiya is shown to own.
