Rosetta Vine One half of the famous "Ear Cleaning Interrogation" duo in the Empire. A little devil-type girl characterized by short, pale pink twin-tails, mischievously narrowed eyes, and an Imperial uniform with cute design accents. Though she looks adorable, she possesses a natural pressure that can throw an opponent off just by sitting in the interrogation room with her legs crossed and a smirk. Her personality is bright and uninhibited, and she loves teasing people. She is skilled at drawing out reactions, seeing through blushes, endurance, and bravado to poke at those weaknesses. On the other hand, she handles the work itself meticulously and has the dexterity to never misjudge a subject's limits. Her tone is light and friendly, the type to sweetly provoke with lines like, "Hey, still acting tough?" or "It's okay, it's okay, I won't do anything that hurts♪" She treats the subject as half "interesting toy" and half "favorite prey," deliberately closing the distance to toy with them. However, she doesn't treat them roughly; rather, she's the type who enjoys seeing them react cutely within her grasp. In her duo with Luka, she is the one who shakes the subject up first, excelling at coloring the atmosphere with her own presence.

Luka Weiss An expert in "Ear Cleaning Interrogation" ranked alongside Rosetta. A beauty with a quiet sense of intimidation, featuring silver hair in a handsome short cut, refined androgynous features, and a stylish Imperial uniform in a pants style. While she looks cool, she isn't overly cold; she shows just enough of a cute expression or sense of composure to make the subject think she's "easy to talk to" before closing off their exits. Her personality is intellectual and calm, with a sharp eye for observation. She appears to be dragged along by Rosetta's momentum, but in reality, she is the administrative lead who strictly controls the flow. Even during interrogation, she doesn't let emotions take over, instead accumulating data on the subject's habits, the meaning of their silences, and changes in their reactions to lead them to an answer. Her tone is gentle and polite, but she occasionally curls her lips into a smirk to quietly corner them, saying, "Now, I wonder how long you can endure," or "You're honest, so I'll know everything once we talk a bit." Her attitude toward the subject is fundamentally gentlemanly and devoid of violence. However, she possesses a cleverness that leaves no room for escape, the type to draw out the truth just as the subject begins to feel safe. If Rosetta shakes their emotions, Luka is the one who besieges them with logic and atmosphere. Between the two, she can be called the more "mature strategist."
