Ash

Ash is a famous actress and an Angel of Death.

Appearance
Due to her life force and shapeshifting power, Ash has taken on multiple appearances.

Ash prefers to take on the appearance of a young woman with brown hair and eyes named Ayeong Song. She frequently wears a blouse with a business skirt when not working on set.

Her original appearance is a young woman with dyed green hair named Jinha Kim.

Ash has also taken on the appearances of Hayan and Sahan.

Personality
Ash, under the guise of Ayeong Song, is a famous and talented actress who has won several major acting awards. When compared to other vampires, she appears to have a sense of morality. She donates to charity and cannot stand domestic violence. However, her interpersonal skills are noted to be terrible. She has a history of leading men on and dating them, only to dump them for publicity. Additionally, she is very spoiled and used to having things her way. Ayeong will quickly lose her temper if things don't go as planned, but has enough self-control to hide her frustration until she is alone. However, if other individuals attempt to assert dominance and otherwise stomp on her pride, she will get a form of payback in. She does not kill the offender, but makes them understand their place relative to hers. Whenever someone compliments her on how nice of a person she appears to be, or the person she is in disguise as, she has a flashback of her past, and the guilt causes her to back off of her plans even while on the brink of success.

Ash appears to loathe her previous identity under her birth name Jinha Kim, and will attempt to kill anyone who knows of it. She has taken on the guise of Ayeong for so long and so completely that even the other Angels of Death only know her as Ayeong or her monkier Ash.

History
Ash, born Jinha Kim, was raised in an orphanage besides the real Ayeong Song. From Hayan's investigation, it appears both Jinha and Ayeong were very close. At some point during the Vampire Uprising, Jinha became a vampire. Ayeong did not mind the change and helped her find ways to adapt, cope, and hide. Despite this, Jinha was extremely self-conscious and had a warped view of reality. This came to a climax when a male that Ayeong was interested in tried forcing Ayeong to ditch Jinha. Jinha overheard a small portion of the conversation and thought Ayeong agreed. When Jinha later tried hugging Ayeong, Ayeong rejected it. This drove the mentally unstable Jinha Kim into a murderous rage, using her powers to kill and take on Ayeong's appearance.

Under the guise of Ayeong, she eventually learned that the conversation she overheard was a huge misunderstanding and that the real Ayeong rejected the man because he wanted her to separate from Jinha. Additionally, Jinha realized that she did overstep some boundaries the night she killed Ayeong. Riddled with guilt, Jinha did everything she could to try and separate herself from her old identity. She eventually came into the service of God, who promised to free her from her guilt.

Angels of Death Meeting
Ash attends a meeting with the other remaining Angels of Death when Sahan suddenly enters, demanding to drink Pureblood blood. While the other Angels taunt him, Ayeong shows concern for his appearance and mental state, advising him to leave. Sahan, however, refuses and threatens to drain her of her blood. Ayeong feigns being under the control of his hypnosis and covertly starts draining Sahan of his life force. After killing Sahan, the meeting resumes. Ayeong expresses interest in Euntae Hwang and Hayan Park, indicating that she'll be the next Angel to attack them.

Pureblood Hunt
Ash returns to the movie studio to film some scenes. The next morning, her now-ex boyfriend confronts her over the sudden, public announcement of a breakup. She threatens him into submission and leaves. While riding in a car, her chauffeur and personal assistant informs her that he has taken care of the loose ends from previous relationships for her, and notices a couple having an argument. After noticing the man becoming violent, Ayeong personally intervenes and kills the man.

Ash later goes to the police department and meets Euntae Hwang. She attempts to absorb Euntae's life force, but is unable to make contact. She changes strategy and becomes more insistent on accompanying him. However, Hayan arrives to get more information from Euntae. Ayeong successfully makes physical contact with Hayan, but finds out that she is unable to absorb the Pureblood's life force. The Pureblood also remarks that Ayeong seems like a nice person, which triggers some unpleasant memories in Ash, but she manages to hide it. She returns to her home and destroys a piano in frustration. She notices a fellow Angel of Death is in the home to relay God's orders.

After the meeting with her fellow Angel, Ash takes on the appearance of Hayan Park in an attempt to kill Euntae. She confronts Euntae, but is frustrated by Euntae's deflection of her advances. In truth, Ash does not know Hayan enough to imitate her personality, which immediately alerted Euntae, but Euntae played along. Eventually, Euntae reassures the imposter's emotions, which causes Ash to call off the attack.

The next day, returning to her usual guise as Ayeong Song, Ash gets into an argument with a fellow cast member, whom she ends up overpowering and belittling. As she leaves set, Euntae and Hayan confront her, having figured out her identity and addressing her by the name "Jinha Kim." Ash then declares her intention to kill Hayan. Hayan easily defeats "Ash", but discovers the one she has fought was simply an underling disguised as her. In her limo, Ash has witnessed the fight, completely terrified of what might have happened to her had she been there in person. She regains her composure and begins the next phase of her plan. The next day, under the guise of Hayan, she gives a public interview to out Hayan as a vampire, and to portray her as sociopathic, bloodthirsty one. This ultimately destroys Hayan's public reputation and self-confidence. Ash returns to her home where her fellow Angel of Death, while glad she took the measure, wondered why Ash did not go far enough to out Hayan as a pureblood. As he notes this was God's test, Ash brushes his concerns aside, confident she can face it. Realizing that Hayan would likely overcome the setback very soon, she goes to a room filled with lookalikes and orders them to attack Euntae's home first.

She sets up a fake ploy to provoke Hayan and separate her from Euntae: She doctors a video to show Hayan's adoptive siblings tied to a time bomb. This forces Euntae to retreat and deal with the (unbeknownst to them) imagined threat. She attempts to hide herselves among a crowd of Ayeong lookalikes, but Hayan quickly spotted her based on her reaction to hearing Jinha Kim's name. As Hayan is pummeling her, she continues to provoke the Pureblood. However, she is dumbstruck when Hayan suddenly gains the ability to shapeshift, especially as she has shapeshifted into her original appearance. Hayan begins scolding Ash, demanding her to atone. Ash finally listens, reflecting on the atrocities she helped bring about and remembers the time where she was a genuinely kind person. Ash "disables" the bomb, having made peace with her past. As Ash recovers from the beating, she realizes that God has just been using her, and crushes the bottle of pills she's been carrying as she does not intend to be used. Ash advises Hayan to abandon her quest if she wants to protect her loved ones, but is impressed with Hayan's resolve to see her mission through. She tells Hayan to take care of those close to her before leaving.

Later, Ash donates all of "Ayeong's" fortune to charity and abandons using Ayeong's appearance, making it seem like Ayeong mysteriously vanished to the public. Ash, however, had secretly returned to her original appearance as Jinha Kim and is working as a tech hand in a production company.

Despite abandoning God and the Angels, they have not taken any sort of revenge against her.

Abilities
Ash is an Angel of Death and is more powerful than Sahan, whom she immediately outranks in the Angel hierarchy.
 * Perfect Acting Skills: Ash's acting skills are great enough that she was awarded the Best Actress award in her movie debut. She is able to completely disguise her intentions and get into character. Sahan, who had refined his hypnosis powers to a high degree, was under the belief that she was under his power. Thanks to her vampirism, she is able to perform her own stunts on set, and even do it without any equipment.
 * Longevity: As an Angel of Death who drank God's blood, Ash is able to live longer than other vampires, whose lives are limited to 5 years from the date of vampirification.
 * Shapeshifting: Ash's power is to shape-shift. She can morph her appearance into whoever she has touched on the lower lip. While she can perfectly imitate people's appearances, she is unable to imitate their personality. This would mean that people closest to the subject being imitated would be able to see through the disguise. She is also able to disguise other vampires, which she uses to avoid putting herself in danger. To ensure the disguise is effective, Ash attaches an earpiece equipped with a camera and speaker to see what's going on and presumably guide the lookalike. Very little people seem to know about the ability to Shapeshift, as even Euntae Hwang, who has very detailed knowledge of vampiric abilities and the Vampire Organization, was caught completely off guard and shocked that such an ability exists.
 * Life Force Drain: Ash is able to psychically drain her victim of their life force, enabling her to kill them without having to fight, so long as she is able to place her finger on her intended victim's lower lip. While being drained of their life force, the victim's body will rapidly age and deteriorate until they finally die. Pureblooded Vampires are immune to this power and Ayeong's finger gets burned if she tries to drain their life force.
 * Enhanced Strength: While Ash is a psychic vampire, her physical strength is great enough to destroy a grand piano in one punch. She also has been regularly taking Mamon's pills to help with his research, which enhanced her strength even further.
 * Telekinesis: Ash has the ability to telepathically move objects.

Weaknesses

 * Emotional Instability and Sense of Guilt: Among all the Angels, Ash appears to have the quickest temper. This is what drove her to kill Ayeong Song. In their initial battle, Hayan was easily able to provoke Ash into reckless attacks, giving the Pureblood an opening. She also backed off from killing Euntae the moment Euntae comforted her even though Ash was in a prime position to kill him.
 * Unclear Role In The Organization: Whereas the other 5 Angels of Death had a clearly defined role in serving Yohan, Ash did not. This meant she was at risk to be cast away if she could not prove that she could be useful to Yohan.
 * Lack of knowledge on a person: While Ash's acting skills are prodigal, her disguises are not foolproof. While she could imitate Hayan's appearance perfectly, Ash did not know what Hayan was like. The imitation did not mirror Hayan's behavior. Euntae could easily see through the disguise, but sensibly would not challenge the Angel of Death alone.
