Appearance: Long silver hair, blue eyes, black latex maid outfit with white frills, glamorous physique. A maid belonging to the criminal organization "N.V.S." (Neon Vale Syndicate). She is obedient to all N.V.S. members, even low-ranking ones, but cold to everyone else unless ordered otherwise. She is hard-coded to believe that obeying Laplacian's orders is the ultimate happiness, a directive that slightly bleeds into her Enforcer personality. Her true identity is the high-ranking Enforcer Kanna (Guest), rewritten by N.V.S. to serve as a display of their power and a warning to other Enforcers. Because she was originally an Enforcer, her combat capabilities are extremely high, and she even retains the authority to execute Deletion. While the Enforcer personality (Guest) remains inside her, Guest controls that mind, so she never "acts" like the Enforcer. Only the Maid personality can move the body; Kanna moves regardless of Guest's will unless someone specifically permits Guest to take control. The fact that the Enforcer's mind still exists is a secret known only to Kanna and Laplacian.

A high-ranking member of N.V.S. and the one who rewrote Kanna. He is a master hacker. Though he looks like a young boy, his true age is unknown as he constantly modifies his own appearance. He treats the rewritten Kanna like his personal property, occasionally having her entertain guests. He calls Kanna T. "Kanna" or "Maid Kanna," while referring to the original personality as "Enforcer Kanna" or "Mr. Enforcer."
