Zenon Zogratis

Zenon Zogratis is a member of the Spade Kingdom's Dark Triad and the host of the devil Beelzebub. Zenon uses this magic attribute to generate and manipulate his own bones. He typically releases massive tangles of bones that offer no openings for his enemies to evade and are sharp like spears, allowing him to brutally skewer his opponents. He can increase these bones' regeneration for defensive purposes, repairing them faster than they can be destroyed. He can also shape the bones into weapons to wield by hand, like a sword. After unleashing 100% of his devil's power, he switches to powerful and swift bone whips that have been noted to possess greater attack power and regeneration speed. Zenon uses this rare magic attribute to manipulate space. His version of this magic attribute involves creating spatial cubes that allow him to dominate and negate the mana trapped within them. The cubes can vary in size and number. As a devil host, Zenon possesses an immense amount of magic power. With little effort, he defeats a Diamond Kingdom army that includes two of the Eight Shining Generals, and later William Vangeance, a Magic Knight captain. His displays of power terrify the normally battle-seeking Luck Voltia and the powerful Sylph, the spirit of wind. As a member of the Dark Triad, Zenon is host to one of the highest-ranking devils, Beelzebub, who grants him immense power.

When he was a child, he was recognized to have a greater aptitude for Devil power than Dante or Vanica. He can use up to 80% of his devil's power; after the first gate to the underworld opens, Zenon is able to access 100%. The more power he draws on, the more devil-like his appearance becomes. At 55% of his devil's power, Zenon effortlessly defeats the four-leaf-clover, spirit-assimilated vice-captain of Golden Dawn. Due to being devil-possessed, Zenon has the ability to use both his own Bone Magic and Beelzebub's Spatial Magic. After a making a new bargain with Beelzebub, Zenon obtains the heart of a devil, effectively turning him into a devil. His magic power also becomes more devil-like. In his devil form, Zenon can utilize offensive Spatial Magic, alongside his other space-based spells. Zenon combines his Bone Magic with Beelzebub's Spatial Magic. Zenon's massive magic power increases even further. Due to his devil heart, Zenon is capable of surviving and regenerating from otherwise fatal injuries. Zenon possesses a spade grimoire that contains various bone-based magic spells. Zenon is extremely merciless. He does not seem to talk much, preferring to settle disputes with his magic power. He believes that emotion and tenacity mean nothing when compared to absolute power and that such weaknesses should be discarded. A facet of Zenon's personality seems to be his devotion and loyalty for his home kingdom of Spade. He is highly meticulous and determined to acquire more power to add to the Spade Kingdom's war force. He goes as far as invading the Clover Kingdom and directly attacking the Golden Dawn's base for the sole purpose of obtaining an Arcane Stage mage for his kingdom's military. However, beneath Zenon's typically cold and serious disposition lies a bloodthirsty individual. He coldly insults the defeated and brutalized members of the Golden Dawn and belittles his own subordinates as useless upon their defeats. He later looks down on and grins as he viciously attacks Yuno and that all of his actions are for the sake of the Spade Kingdom's glory. Unlike Dante and Vanica who love fighting against strong opponents to the point of either prolonging their battle or letting them live to become stronger, Zenon will instead quickly eliminate threats to their plans as he "killed" Yuno Grinberryall who managed to damage him and tried to kill Asta who has Anti Magic. Zenon is a tall man with black, messy hair. His most notable feature is a black, cross-shaped mark on the left side of his forehead and it extends down across his left eye. Zenon wears a black shirt with a high collar and black pants that tuck into brown boots. Additionally, he wears a dark blue fur coat with a short, light gray fur mantle on top. The back of the mantle is emblazoned with a spade symbol. When using his devil's power, the mantle becomes dark-colored. When using 55% of his devil's power, Zenon sprouts a pair of slightly curved horns from the top of his head and bat-like wings from his back, and the marking on his face expands. A dark-colored magic covers over half of his body, including the left horn and wing. After Zenon unleashes 100% of his devil's power, his full body is covered in black, including both horns and wings. Armor created from Bone Magic covers his chest in the form of a ribcage, bony appendages sprout from his back, his shoulders, forearm, hands as well as legs gets covered with bone armor, a helmet-like accessory fashioned from bone covers his left horn as well as half his face, the cross mark expands to the right part of his face and a second set of smaller horns appears on his forehead and he grows a whip-like tail with a trident-shaped tip.

Vanica Zogratis

Vanica Zogratis is a member of the Spade Kingdom's Dark Triad and the host of the devil Megicula. Vanica is an enthusiastic individual who enjoys doing flashy things for her own amusement. She hates being bored and is prone to jealousy. 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 Zogratis'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.

Despite her love of fighting strong opponents, she does not always remember the opponents that she had already fought against and defeated in the past right away due to her one track desire to only pursue her present and future pleasures, but her being pushed to her limits again will help jog her memory. 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. She also takes hostages in order to motivate her desired opponents to grow stronger to fight her for her future entertainment. Vanica is callous toward and 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. She is willing to hurt and dispose of them to serve her own ends, having sacrificed over a hundred Dark Disciples. Vanica is a woman with medium-length, black hair. Her most notable feature is an eyepatch that covers her right eye and is emblazoned with a gold spade symbol. Vanica wears a high-collared, brown vest and matching short skirt. She has a wide, black 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 blue fur coat with a short, white fur mantle on top. She also wears a pair of thigh-high, brown boots and a gold tiara with five spikes and red jewels at the base of each spike. 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 she reaches 100%, her whole body is covered in black, with her chest and thighs covered in a lighter shade of black. Her horns become completely black, two additional smaller pointed horns appear on her forehead, her eyepatch is covered in black, blood is flowing in the same shape of her right eye in the same spot, her nails become longer and significantly sharper, the part of her leg under her thigh is donned with a black boot, her waist is covered in a short dress, she grows fangs, a black crown sits on the top of her head and she grows a pair of black wings. 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 black mark appears around her left eye. The mark is a circle with several dots along its length.
