Appearance
Tabula's appearance is that of a humanoid with a head resembling that of a distorted octopus, covered with crooked text tattoos. He has two pupil-less, blue-white murky eyes and his skin color is deathly pale like a corpse. He wore a black cloak decorated with silver accessories and several loosely-fitted belts.

Personality
Tabula Smaragdina has two passions: "gap moe", which is the cute contradiction between the actions of someone and his or her usual character, and horror films, of which he had an extensive knowledge, from the classics to the latest, that surprised even his fellow guild members. His creations Albedo and Nigredo embodied respectively these two hobbies.
