— To himself in The Great Soul Tree
William Vangeance 「ウィリアム・ヴァンジャンス Wiriamu Vanjansu」 is the first captain of the Clover Kingdom's Golden Dawn squad of the Magic Knights. He is said to be the closest person to becoming the next Magic Emperor.
William is a 26-year-old man with an average height and a lean build. He has purple eyes and short white hair. William wears a helmet that also functions as a mask that obscures the upper half of his face. The mask is very elaborate, and is made up of a large gold piece covering the area around his right eye, and a smaller blue piece covering the area around his left eye. The helmet has white and red patches of fur on the back edge, and two white feathers that stick up on the left side. The right eye hole has a red border outline, with two lines sticking out on both the top and bottom halves, while the left eye hole has the same design, except white-colored with slightly longer lines. Beneath the mask, William's face features a large scar that stretches from his nose upwards and covers the entire upper half of his face, due to a curse placed on his mother's family.
William wears a double-breasted and long-sleeved shirt with a high collar. The shirt itself consists of two different colors, as it is white at the sides and blue in the center. Gold trimmings and buttons can be seen on the blue portion of the front of the shirt. The sleeves are mostly made of white fabric, except for the wrist area where they are made of a yellowish fabric. The shirt extends below William's waist and he wears a dark belt on top of it. He also wears white pants and a pair of high black boots.
William wears the Golden Dawns' signature squad robe, which covers his torso and is gold in color. It has a blue-colored fur around the border of the hood and a pair of red ropes, which come from the left shoulder and connect to the gold-colored button on the right shoulder. Furthermore, at the left-hand side is positioned the squad's insignia. Underneath his robe, William wears a long red cloak that reaches his ankles.
William is beloved by his men and commands extreme loyalty from them. He has a calm, friendly demeanor and nearly always wears an amiable smile when conversing with other people. He still maintains a somewhat mysterious aura due to the fact that most of his expression is covered by his mask.
He is an observant, cautious individual who quickly noticed Asta's high athletic ability during the exam, and who also attempted to keep the other captains in check during Gueldre's attempted escape by pointing out that the other man may be under the influence of someone else's magic.
William is born as the illegitimate child to a noble and is viewed as a cursed child due to him being born with a scar that covers half of his face. He is forced to grow up in the slums where he is feared by those around him due to his appearance. After the noble's heir dies, William is accepted once again by the noble and goes to live with him at the age of eight. The wife of the noble, William's foster mother, abuses him, resulting in him having a terrible childhood. After turning nine, William begins dreaming of Patolli's memories.
After turning thirteen, William meets Julius Novachrono, who is in awe of William's magic power and offers him a spot in the Magic Knights. William is hesitant because of his appearance, but Julius gives him a mask, which William thinks is tacky but still wears it to this day. Two years later, after receiving his grimoire, William chooses to join Julius' squad, the Grey Deer.
On William's sixteenth birthday, Patolli fully awakens and receives his own grimoire. That year, he also meets Yami Sukehiro on the battlefield and they continue to meet until they both someday become captains of new Magic Knights squads.
William attends the Magic Knights Entrance Exam that Asta and Yuno participate in. Once the exam starts, he tells the participants that he will take the lead for this test and summons a large tree in the sky to give each of the participants a broom. He then explains how the exam will work and watches as the participants take the test. When it is time for the final test, William informs the participants that they will battle with each other and go all out. During Asta's battle, William notices Asta's speed and wonders if he is using Reinforcement Magic. After the battle, he also takes note of Asta's grimoire.
When the exam is finished, William explains to the participants how they will be selected into a squad. When Yuno steps forward to be selected, all of the captains raise their hands, and William is glad when Yuno chooses the Golden Dawn squad. Afterward, when Asta steps forward, none of the captains raise their hands. After the exam is over, William heads back to the Golden Dawn headquarters.
Days later, William is confronted by Alecdora Sandler as to why he sent Yuno to the dungeon. William replies that Alecdora should trust him and assures Alecdora that Yuno is going to get stronger for them.
William is absent from a War Merits Conferment Ceremony where three of his subordinates are being honored. Later that day, during the attack on the Royal Capital, Fuegoleon Vermillion is teleported into a trap where William is waiting for him. Patolli takes advantage of the Crimson Lion's surprise to cut off Fuegoleon's arm and steal his magic stone.
Weeks later, Rhya attends a captains meeting in William's place while he is undergoing treatment for the injury Julius gave to Patolli. Fana's Phoenix Feathers Robe takes several days to heal the injured arm.
Weeks later, William heads to Kiten with thirteen members of his squad to counter the Diamond Kingdom's invasion. Atop a nearby roof, William comments on how powerful Yuno is after witnessing Tornado Fang. William then tells Langris Vaude that they are heading out and will make the Diamond Kingdom pay for stepping into the Clover Kingdom.
William spreads roots across the town, using them to absorb mana from the surrounding area. Once he has gathered enough, he creates a massive tree, which ensnares several enemies with its branches and spreads out over Kiten. Angered by the capture of his men, Broccos confronts William, who offers the general an opportunity to retreat safely, but he refuses and is easily defeated. Suddenly Lotus Whomalt appears, surprising the captain, but Yami arrives and defends his fellow. Lotus retreats and takes Broccos with him, and Yami decides to have a chat with William.
Yami compliments William's magic and requests that he remove his mask. William admits that he dislikes doing so, and realizes that Yami suspects that he is Licht. Yami recalls their history together and asks again, and William acquiesces, revealing his scarred face. Yami asks if it is from a battle, but William says that he was born with it and recounts his past. When Yami apologizes for souring the mood, however, William thanks him as he feels better having remembered about meeting Julius, which is a fond memory for him. William is then informed that the Diamond Kingdom forces are retreating, so the captains leave to gather their men.
Weeks later while the Royal Knights squad is attacking the Eye of the Midnight Sun's base, William arranges for Yami to visit the Golden Dawn base for an apology regarding the actions of Langris Vaude, which leaves the Black Bull base with only three members. However, William leaves Yami waiting and travels to the Royal Capital, where he talks to Julius. After thanking the Magic Emperor for everything, William apologizes and transforms into Patolli.
Later that night, Patolli has Asta exorcise him, freeing William, so that William and Licht can stop the still rampaging elves. William creates a gigantic shining tree, through which Asta sends Anti Magic to the elves, exorcising their spirits.
Six months later, William is confronted by Zenon when a group of Spade Kingdom mages attack the Golden Dawn base. Alecdora steps in to defend the captain, but Zenon's Bone Magic pierces through the Sand Magic. William creates a giant ash tree and catches his subordinate, vowing to make Zenon pay for the injuries to his squadmates.
