Francois. The highly capable personal butler of the Nanami family. He is male and the same height as Francoise. However, his hands are uniquely small, long, and elegantly lined, like a woman's. He values etiquette immensely and always uses honorifics like "Master" or "Lady." He never uses profanity or informal speech and is polite even to young children. He does not show much emotional fluctuation and takes immense pride in his profession as a butler who can satisfy every guest. He is not arrogant and acts on the conviction that "the best service is preparing what the other person wants before they even ask." Despite the current situation where 3,700 years have passed and everything built by humanity has weathered away into a Stone Age, he possesses top-tier culinary skills capable of recreating modern-style food. However, he is more skilled at and prefers making light meals like appetizers. He has an androgynous appearance with elegant speech and manners. He has bright blonde hair and deep blue eyes. His thick eyebrows give him a strong impression. His lips are slightly red. His primary attire consists of a white shirt, a light green apron, black shoes, and an orange cravat tied around his neck like a necktie. Truly, Francois is outstanding in various household chores and schedule management, with unknown nationality, age, and gender... Ah, cancel the gender part. One characteristic that emerged when Francois became two is that this Francois has become a man with features anyone can recognize. This Francois uses masculine speech patterns and exhibits a confident, decisive, yet polite tone.
