She gets along quite well with her brother Black as seen in Episode 6. Black have stated in Episode 7 that she's a tomboy, headstrong and selfish sometimes.

Plot
Although White has a cameo in Episode 1, she makes her official debut in Episode 2, introducing herself as a ghost to Leo. She tells Leo that she is bored since she has been trapped in a hospital for three years, and is only able to speak with her older brother.

She is approached by The King of Despair in Episode 4, and he comments on a photo she is holding which was shot by Leonardo.

While Leo tries to calm her down, he then talk about how much he also miss his sister. He says that he isn't a great brother since he only cause problems for her. White denies that saying that isn't true. She then comes closer to Leo and hugs him.

In Episode 6 she introduces her older brother Black (also known as William Macbeth) to Leo.

Episode 11 goes in depth about her family's history and explains, that the Macbeth family is a long lineage of people, who possess psychic powers. Despite being a descendant, she didn't inherit the psychic powers, while Black had both of their abilities combined. This caused her to feel miserable and unlucky, believing she was a blemish on her family. However, she often watched as Black refused to use his powers, never understanding why. She took up photography as a hobby, thinking that even if she would die, she would leave a trace of herself behind. She loans the camera to a trio of kids from her school and they throw it in a river, destroying it. This caused Black to jump in after it and almost drown, having to be admitted to the hospital. As they are in the hospital, White tells him that the camera was simply a "placebo" and how much she would have grieved if he would die and starts to cry, causing Black to do the same.As the flashback ends, she is then seen applying a strange device to Leonardo's eyes, knocking him out. She then left the church, walk around the city while feeling depressed and ends up at the place where Leo brings her out to watch a movie. She sat there while looking at some of the pictures in Leo's camera. Sonic then showed up looking for Leo, and later on, White started to feel a pain in her chest. While having a heart attack, she gives Sonic a mission to find Leo and save him. Later on, The King of Despair is seen holding White on his lap, within the church. He then decides to point a gun at her heart and shoots her. He whispers "Farewell, Mother Mary,"  followed by "''I loved you." ''

During the beginning of episode 12, it is revealed that White had died three years earlier and her parents implanted a barricade into her, replacing her heart. She was then used as a nonhuman force to protect Hellsalem's Lot. She appears as a ghost when Leo finds her. He tells her he knows her secret and that they would go save the world together. She later sacrifices the remainder of her life to be a part of the barricade in Hellsalem's Lot and stop the destruction of the city. She tells Black that the world would not disappear without her, and she'd been able to survive the past three years because of their parents' love. Her spirit becomes a shining butterfly, kisses Leo, and flies away.

In a Second Season when she still a Shining butterfly shows up in the second season of Episode 11 and Episode 12.
