Sigmund

Sigmund is an ancient dragon-type automaton with over 150 years of existence, classified as a 'Forbidden Doll' and treasured heirloom of the Billo family. In peaceful times, he takes the unassuming form of a miniature dragon perched upon Charlotte's shoulder, but when battle calls, he transforms into a colossal steel-scaled dragon capable of wielding a unique magical circuit known as the 'Magic Sword,' which possesses the power to erase space itself. Calm, gentlemanly, and wise beyond measure, Sigmund serves not only as Charlotte's most powerful combatant but also as her trusted mentor and steadfast protector — though his legendary composure tends to crumble completely at the sight of a well-cooked meat dish.
