Mare Bello Fiore/Relationships

Ainz Ooal Gown
As the absolute ruler of Nazarick, Ainz has Mare's complete respect, admiration and loyalty and that he has pledged to serve him without hesitation. Originally, Mare believed that Ainz was a much scarier person, but was quite shocked when he and his sister witnessed his compassionate side that he showed to his subordinates.

Bukubukuchagama
Bukubukuchagama is Mare's creator. She programmed him to be a pushover whom is constantly ordered around by Aura. This is because of her belief that the younger brothers should listen to their older sisters. She also dressed him like a girl, for some unknown reason.

Aura Bella Fiora
Mare is the submissive one between the pair of twins, with Aura ordering him around.

Albedo
Mare appears to be quite scared of Albedo and stays clear of her if possible.

Shalltear Bloodfallen

Demiurge
Mare gets along well with his fellow Floor Guardian, Demiurge. He often explains things to Mare if he doesn't understand him.

Victim

Yuri Alpha
Mare is close enough to Yuri to the point they refer to each other with nicknames outside of work. That is because the Supreme Beings who had made them were close to each other, and they felt similarly close to each other.

Titus Annaeus Secundus
Out of all the other denizens within Nazarick, Titus would qualify as Mare's closest friend since they have a lot in common and would prefer to remain alone and isolate themselves if they could. Aura had stated that Mare often visits the Grand Library, and shares similar interests with Titus in literature.

Librarian J
Mare is a frequent visitor to the Grand Library, so the elder lich is accommodating to the Floor Guardian.

Pestonya Shortcake Wanko
