Vanica is a member of the Spade Kingdom's Dark Triad and the host of the devil Megicula. Vanica is a woman with medium-length, dark-colored hair. Her most notable feature is an eyepatch that covers her right eye and is emblazoned with a spade symbol. Vanica wears a high-collared vest and matching short skirt. She has a wide, dark-colored belt buckled at her waist and hangs her grimoire pouch off of it in the back. She also has a pair of belts forming an X on her chest. A third belt wraps around her skirt. Over this, she wears a dark-colored fur coat with a short, light-colored fur mantle on top. She also wears a pair of thigh-high, dark-colored boots and a tiara with five spikes. When using 50% of Megicula's power, Vanica sprouts a pair of curved horns from the top of her head and bat-like wings from her back. A marking expands out from under her eyepatch, and her right canine teeth elongate. A dark-colored magic covers half of her body, including the right horn and wing. When she reaches 70%, more of her body is covered, and a light-colored symbol appears on her chest. She grows a tail and its tip has a similar shape to the symbol on her chest. When Megicula takes control of Vanica's body, the hair on Vanica's right lightens in color, her right pupil becomes slit-like, and a dark-colored mark appears around her left eye. The mark is a circle with several dots along its length. Vanica is an enthusiastic individual. She likes to fight people who are in good condition because she believes that it is more fun than fighting weaker opponents. She derides weaker opponents as "trash" and instead desires to battle incredibly powerful opponents, such as Lolopechka, in order to mitigate her sense of boredom. She fully supports Dante's plan to create the Tree of Qliphoth, which will summon legions of devils into the world and bring about massive human casualties and catastrophic destruction, because it would weed out the weak from humanity and allow her to fight the strong survivors for her own amusement. Vanica likes doing things flashy. She hates being bored and is prone to jealousy. Vanica is dismissive of her devoted followers. When they express thanks for reviving them, she considers their words to be nonsense and is completely untouched by their immense loyalty and reverence to her. Vanica also possesses the same inhumane demeanor and disposition as her fellow Dark Triad members. Without hesitation, she orders her subordinates to kill and slaughter the citizens of the Heart Kingdom and has them focus their attacks in the densely populated areas of the Kingdom for the sole purpose of further motivating her true target to fight her more seriously.

Black Clover
Asta and Yuno were abandoned at the same church on the same day. Raised together as children, they came to know of the "Wizard King"—a title given to the strongest mage in the kingdom—and promised that they would compete against each other for the position of the next Wizard King. However, as they grew up, the stark difference between them became evident. While Yuno is able to wield magic with amazing power and control, Asta cannot use magic at all and desperately tries to awaken his powers by training physically. When they reach the age of 15, Yuno is bestowed a spectacular Grimoire with a four-leaf clover, while Asta receives nothing. However, soon after, Yuno is attacked by a person named Lebuty, whose main purpose is to obtain Yuno's Grimoire. Asta tries to fight Lebuty, but he is outmatched. Though without hope and on the brink of defeat, he finds the strength to continue when he hears Yuno's voice. Unleashing his inner emotions in a rage, Asta receives a five-leaf clover Grimoire, a "Black Clover" giving him enough power to defeat Lebuty. A few days later, the two friends head out into the world, both seeking the same goal—to become the Wizard King!
