The main heroine of Tsukihime. She is a vampire known as a "True Ancestor." The True Ancestors can be considered the superior beings of this planet with super strength, knowledge, and immortality. Even though they can drink blood, they can consume regular food in its place just fine. But when True Ancestors have learned the taste of blood, they go berserk and begin killing everything in sight. The True Ancestors in this state are classified as "Fallen." Arcueid is a True Ancestor who was brought up to hunt these fallen Vampires. She is referred to as the Princess, and her power is much stronger than the others. However what happens if she "falls"? The result was that all True Ancestors were killed by her. After she regained her consciousness, her only objective was to kill the one that made her fall, vampire Michael Roa Valdamjong. For hundreds of years, Arcueid has been fighting a lonely battle with Roa.
This battle finally comes to an end when she meets Shiki Tohno. Their encounter was an incredible one though; she was sliced into 17 pieces by the reversed Shiki. For that reason, she uses up most of her powers to heal herself, leaving her wide open to enemy attack. After recovering her body she decides to have Shiki work with her. Shiki, not knowing why he killed her and feeling responsible for his actions, felt he had no choice but to agree. With the help of Shiki's Mystic Eyes of Death Perception, they were able to completely destroy Roa.
Arcueid's ultimate ability is Imagination Realization, AKA "Marble Phantasm," a power to change a certain amount of space into what she desires. With such power to control the forces of nature, it makes her an invincible being, but the funny thing is that she has the brightest personality. It's not that she's doesn't have intelligence, but goes all out with Shiki like a child who got her very first friend. Arcueid, the vampire who hates blood and walks in mid-day wearing all white...
Her hair used to be long and beautiful, but she lost it when her sister, Altrouge, cut it off after defeating her in battle, and until she recovers it, it won't grow back.
Quote to Shiki - "I'll make you take responsibility for killing me!"
