Luck Voltia is a 5th Class Junior Magic Knight of the Clover Kingdom’s Black Bull and Royal Knights squads. He is also the human vessel for the elf Lufulu. Luck is a young man of short stature with blue eyes and medium-length messy blond hair. His hair is long enough to cover both his ears and forehead.

Luck’s outfit is very simple and consists of an aqua-blue tunic with long sleeves. The sleeves get larger as they reach Luck’s hands, making the tunic appear loose. Additionally, the tunic’s length extends just below his waist, making it look to be a size larger for Luck. His pants are teal and extend just below his knees. Additionally, it has light-colored strips with stitch-like cross patterns at the sides, running from top to bottom. Luck also carries a pouch for his grimoire, which is strapped around his chest with the use of a belt. Finally, Luck wears a pair of light-colored brown boots that cover just above his ankles.
