Personality
Vael initially is portrayed as Yohan Seo's most loyal Angel. He is very calm and level-headed compared to most of the other Angels of Death and does not lose his temper. He usually speaks courteously and respectfully to others. However, he will not accept challenges to his rank in the hierarchy and is prepared to fight even other Angels. He also looks down upon failures, stating that God did not want to see Sahan and noting Sahan's nerve showing up to a meeting after his complete failure. Sahan, however, is not blindly loyal to Yohan and is able to see the shortcomings in Yohan's tactics.

Secretly, however, Vael was only pretended to be loyal to Yohan in order to save Daniel. In truth, Vael despises Yohan's wickedness and sought ways to undermine him and protect innocent people. Upon learning that Yohan's blood wasn't 100% Pureblood, and switched loyalty to Hayan Park.

He would do anything to protect Daniel.

Synopsis
Vael is alluded to by a lesser vampire, who explains that the 6 Angels of Death are on an entirely different level of power than regular vampires, and so the lesser vampires should simply bow and show respect.

Vael attends an Angel of Death meeting, when Sahan bursts into the meeting room. Vael, along with some of the other Angels, taunts and admonishes Sahan for his failure, and declares that God does not have time for a failure such as Sahan. Vael watches as Ash confronts and kills Sahan. After Ash declares her intentions to hunt Hayan, Mamon privately confides with the other two Angels his concerns over Ash's eagerness and the fact that the Angels were instructed to hunt her one by one instead of as a group. Vael explains that Ash is the only Angel with an unclear role in the group, and advises Mamon to follow God's orders.

Vael then visits Ash in her home after her failed to attempt at draining Euntae and Hayan's life force. He taunts her for being a child when things don’t go her way. He relays a message from God to not jump the gun. He tries to show concern towards Ash for not having a plan, but she brushed it off, insinuating that he feared Hayan. As Ash becomes increasingly irritated with these orders, she threatens Vael that he will have the same fate as Sahan. He then leaves stating he doesn’t want to fight and reminds Ash of the importance of patience and what they’re planning to do next.

A few days later, he returns to Ash's home again where he is sipping a glass of blood and watching the aftermath of Ash revealing that Hayan is a vampire. While glad she took the measure, he asks why she did not go far enough to out Hayan as a Pureblood. He notes that this was God's test but once again Ash brushes off his concerns confident she can handle it, telling him to worry about himself.

A few days after Ash is defeated by Hayan, she disappears, leaving the rest of the angels to continue with the project. They are gathered in a new hideout. Vael is trying to calm Mamon's frustration towards Ash when God steps in. Vael begins to see Mamon as a liability and decides to keep an eye on him. As God enters, every vampire in the room bows, and the meeting starts. God states that why hasn’t anyone been able to bring the purebloods heart. Vael takes into account the tension in the room as palpable. He seems to be aware that the vampires are noticing that the system is breaking down since the highly followed Angels of Death are being killed off. Mamon tries to calm down the murmurs only to have one male vampire asking God for a chance to take the place of the missing Angels. Vael sees that the other vampires are being swayed by what the male vampire said. God approaches the individual and asks if anyone else wants to be an Angel of Death, to which two more males and a female vampire respond. Their dreams were short as they were killed. With fear consuming the crowd, the meeting resumes. Mamon informed that all preparations had been completed and that he would be the one to pursue the pureblood. Vael warns Mamon about the risks. Mamon, however, assures Vael he has a plan. As the meeting ends, Vael then mentally notes that every time an Angel fights Hayan, Hayan always wins and gains more power. He wonders about Yohan's true intentions, but decides it is unimportant as long as he gets his reward.

After Hayan fully regains her memories, he confronts Euntae Hwang and Hayan as they are travelling to Mamon's lab. Euntae offers to fight Hayan, but after a brief fight, Vael backs away. He declares his true intention of confronting them was to secretly defect and pledge loyalty to Hayan. This does not work as Hayan is too jaded of vampire intentions to believe them, especially from one of Yohan's top lieutenants. Vael recognizes this, and noting Hayan's glowing heart, realizes he was too bold in his actions. He decides to leave them with a bit of information to help them: the location of Yohan's hideout and a warning to avoid confronting Yohan. He returns to Yohan's side, reporting Hayan's glowing heart to him.

Yohan assigns Vael to kill Euntae Hwang. Vael makes his move, sending his pet crows to attack Euntae and Hayan on the highway. After exchanging taunts with Euntae, he immediately attacks him. Vael notices Euntae's nearing the end of his life. When he separates and pins Euntae, he discreetly warns Euntae (and Hayan, who is listening through an earpiece) that other pureblood vampires are watching the battle. He notes they are armed with pistols and poisonous bullets that can even kill an Angel of Death. Vael instead proposes to pretend to kill Euntae while they secretly flee to Vael's hideout.

Once their, Vael and Euntae exchange taunts again, but Hayan changes the topic to why Vael is helping them. Vael explains that while as an Angel of Death he can live longer than normal mixed blood vampires, therefore making his need to drink Hayan's blood moot. However, he explains that Hayan's blood is meant for one of his companions: Daniel, his pet lion. Vael explains that he and Daniel have been close companions since Daniel was a cub, and that 5 years ago, Vael let Daniel drink his blood, thus turning Daniel into a vampire. He notes, however, that Daniel is nearing the end of his life. Hayan tries to warn Vael that a vampire drinking a pureblood's blood would end up killing them due to incompatible blood. Vael, however, is aware of this and has theorized another possibility. Through many observations of rare instances where vampires seemingly live despite getting another vampire's blood, Vael has noticed vampires who get new blood at the moment they die will live. He believes this is because at that very moment, the vampire blood will disappear completely from the dying vampire's body, thus eliminating incompatibility issues. Vael again presses Hayan to help him, but is pushed back by Euntae.

Later, Vael tracks down a politician who is advising against using the fake vaccine and seemingly assassinates her as he did with all the other missing people who tried discouraging the vaccine use. Hayan and Euntae confront him about this, but learned that he pretended to kill his targets and hid them away to make it appear he was loyal. Unfortunately, later that evening, Yohan visits Vael and is fully aware of his betrayal. Yohan, surprisingly, says he'll spare Vael. But, in exchange, Vael will perform a magic show in front of an audience that Yohan invited, and kill the audience at the end. The audience will be made up of people cautioning against the use of the vaccine.

Vael, shocked by the demand, initially contemplates suicide with Daniel, but is unable to bring himself to do it. He instead prepares to do the show while planning to undermine Yohan's plan and save the people. At the finale of the show, he goes into the audience and catches Yohan off guard by inviting him up as an audience participant. He exposes Yohan's true identity as the vampire behind the decade-long crisis. Yohan attempts to turn the tables with hypnosis to make the audience completely forget everything, but Vael intended for this to happen as it would mean the audience would safely leave and be safe.

Vael readies to fight Yohan, but is easily overpowered and his attacks having no effect on Yohan. Vael realizes this and prepares to accept his fate fighting. Just as Yohan was about to deliver a finishing blow, Daniel rushes in and protects Vael, and both combatants are shocked the lion has the eyes of a Pureblood.

Abilities

 * Angel of Death: As an Angel of Death, Vael is one of the strongest vampires in Yohan's army. His power, however, is still no match for even an imperfect Pureblooded vampire like Yohan.
 * Keen Intellect: Vael is able to see the flaws in Yohan's strategy and detect that Yohan's outward motives may not be genuine. However, he wisely keeps these thoughts to himself to avoid Yohan's wrath. Vael is also able to deduce possible reasons on why some dying vampires are able to survive receiving another vampire's blood while others don't. As a former magician, which specializes in illusions, Vael knows how to disguise his intentions and has above average tactical ability
 * Animal Tamer: Vael is able to tame exotic animals. He often appears with a giant lion and appears to be able to control it.
 * Master Magician/Illusionist: Vael was a popular magician prior to joining the Angels of Death. He uses his knowledge of illusions to his advantage, and presumably uses it to help convince Yohan's minions that he successfully killed Euntae, but has instead hid him in a safer location.
 * Pyrokinesis: Vael's special ability is to ignite objects, causing them to burn, and turn them into remote bombs. He is able to create a very large quantity of bombs at once. He prefers to use playing cards as his medium to attack.
 * Extreme Speed: Vael has been noted to be fast enough that the GPS tracking device secretly planted on him could not keep his location up to date.

Yohan Seo
Yohan is Vael's boss within the vampire empire. It is implied that Vael acts as his right hand man. Vael seemingly is very loyal to Yohan under the promise of getting a reward. Vael's loyalties, however, is more complex. Vael is aware that Yohan isn't exactly a Pureblood. Because of this knowledge and his goal of healing Daniel, Vael appears to be no longer interested in working for Yohan and instead went to pledge loyalty to Hayan. Vael will still carry out Yohan's orders to maintain the guise of loyalty, but unbeknownst to Vael, Yohan has become suspicious of him.

Daniel
Daniel is Vael's pet lion, whom Vael knew since he was a cub. Vael is very close to Daniel and is able to understand what he says. Vael loves Daniel dearly and is willing to betray the Angels of Death to help extend Daniel's life.

Hayan Park
While initially enemies, Vael appeared to switch loyalty to Hayan if it meant he could save Daniel. Hayan, though cautious, is willing to listen to Vael if his theory on blood consumption is correct as it would mean there was a way to save Euntae. After learning of Vael's sincerity and deception against Yohan, Hayan appears to be more sympathetic and friendly towards him.

Euntae Hwang
While Euntae is Hayan's closest ally, Euntae and Vael have a very uneasy relationship. Euntae is (justifiably) very cynical of Vael's intentions despite Vael helping him. The two also seem to have a sort of rivalry and will frequently taunt each other. Euntae, notably, is unusually protective with Hayan when around Vael.
