- "Same...same sixth Floor Guardian Mare Bello Fiore, at your command."
- - Mare's Introduction
Mare Bello Fiore (マーレ・ベロ・フィオーレ) is a dark elf and one of the twin Floor Guardians on the 6th Floor of the Great Tomb of Nazarick. Mare is the twin brother of Aura Bella Fiora. Alongside his sister, he was created by Bukubukuchagama.
Mare is a child with dark skin and pointed ears, a signature trait of the dark elves. He has golden hair and heterochromia, his right eye blue and left eye green.
He wears a blue dragon scale leather full body suit, covered by a white and gold vest embroidered with the sigil of Ainz Ooal Gown and a forest green-leaf cloak. Below, he has a matching short white skirt exposing his thighs, and on his neck is an acorn necklace emitting silver light. His slender hands are donned with shiny white silk gloves and wields a twisted black wooden staff.
People outside of Nazarick, always mistake him for a girl, due to how he looks appearance-wise and the clothing he mainly wore.
Mare has a shy and cowardly personality, the kind which is polar opposite to his sister, Aura. He often stutters when speaking and maintains a subservient demeanor during conversations. This, however, is only an outward guise and does not affect his loyalty to Ainz or his ability to carry out his duties, no matter how cold-blooded they may be. Mare likes to sleep all day and is fond of reading books from Nazarick's library Ashurbanipal instead of talking with others.
Unlike his sister who has an interest in collecting beast species, Mare takes an interest in collecting plant species.
Mare was created to be the brother of Aura by Bukubukuchagama. The reason why Mare is so submissive to his sister, Aura stems from his creator Bukubukuchagama, who apparently believed that the younger brother should obey the elder sister. (Gag between Peroroncino and Bukubukuchagama).
