Elizabeth Bathory

Elizabeth Bathory is a witch invited to the Walpurgis. Titled the "Blood Witch" (『血』の魔女, “Chi” no Majo), her desire is Torment.

She is a noblewoman and Serial Killer who is sometimes referred to as a vampire, due to the belief that she has vampiric tendencies.

Appearance
Elizabeth is a beautiful woman with a youthful appearance, long white hair and pale skin.

When she made her first appareance, she wore a long red dress that shows her cleavage, decorated with dark metalic ornaments around her waist and neck, alongside black high heels.

Her witch symbol is in her left boob and it possess the shape of a heart made out of a chain.

Personality
As a young child, Elizabeth was a very excitable and friendly girl with a fascination towards beautiful people, especially women.

However, after she accidentally killed one of her maids, Elizabeth's innocent attraction became corrupted, quickly warping into a twisted obsession with destroying the beauty of others (or as she puts it "defiling it"), leading her down a dark path of murder and bloodshed.

Now, Elizabeth is fixated on torture and the suffering of others (which is cataloged as her "desire"), being visibly excited by the act of inflicting pain on others and watching them react to it.

Elizabeth also hates people who use the word "justice" and try to perform justice, seeing them as hypocrites who use a vague word carelessly.

Past
During her childhood, Elizabeth was a friendly girl with a fascination towards beautiful people, especially women. However, after she accidentally killed one of her maids, Elizabeth's innocent attraction became corrupted, quickly warping into a twisted obsession with destroying the beauty of others. This led to her becoming a Serial Killer and killing around 650 women in order to satisfy her desire for torment.

As a noblewoman, Elizabeth abused her privileges and political power to abduct and torture young girls and women. At the brink of her death, Elizabeth Bathory was offered a contract by the demons and accepted the invitation to participate in Walpurgis.

Witches' Gathering
After accepting the invitation, she was taken to hell where she waited for the other participants to arrive. After all 32 participants were gathered, Elizabeth was taken to the Coven Arena, where the tournament could beggin.

Walpurgis: Round 1 - Match 1
Elizabeth faced Tomoe Gozen in the very first match of Walpurgis. Despite her best efforts, she lost the match and therefore had her soul banished from reencarnacion.

Abilities
Overall Abilities: Elizabeth is one of the worst serial killers in history, killing around 650 women in total. Despite never being in a real fight before, she was still capable of keeping up with a trained soldier and superhuman like Tomoe Gozen. Due to her past, Elizabeth is very good at using torture tools in order to torment and kill others.

Physical Abilities
Enhanced Strength: Elizabeth was able to compete with Tomoe, who is described as having the strength of a thousand people. She was also able to crack the floor of the Coven Arena.

Enhanced Agility: Elizabeth has displayed immense agility, being capable of keeping up with the superhuman Tomoe and dodging most of her attacks. She can move very quickly through the battlefield, despite wearing high heels.

Enhanced Endurance: Despite having never been in combat before, Elizabeth showed herself to be quite tough for a noble. She was able to continue fighting even after taking a hit that almost sliced her torso in half. After having one of her arms blown off by Tomoe's First Arrow, not only was the sadistic noblewoman able to remain standing in spite of her injury, she also managed to endure having it cauterized with red hot irons (in order to stop the bleeding).

Fighting Abilities
Master of Torture & Torture Equipment Proficiency: After years of inflicting pain and suffering onto young woman, Elizabeth has become an expert in the art of torturing others to death. She has a lot of experience with a great variety of torture tools, being capable of using them in combat. She was also shown to be quite talented at using weapons in general, being capable of wielding weapons and tools that didn't even existed during her time period.

Supernatural Abilities
Witch Power: Like all the other witches that have formed a contract after being invited to Walpurgis, Elizabeth has access to supernatural abilities by using her desire as a fuel source. This power has two uses:
 * Demon Wardrove: Like all witches, Elizabeth can create an unique weapon and armor using her "desire". The armor makes her immune to nonmagical weapons and attacks. The same applies to the weapon, which can be used to pierce magical defenses and can only be destroyed through magic.
 * Magic: Like all witches, Elizabeth can manifest her "desire" as a form of supernatural phenomenon. Due to her desire to inflict pain upon others, Elizabeth magic, which is called Blood Magic, manifests in the form of torture instruments. Elizabeth can create and control any torture device that has ever existed, alongside a great variety of weapons. However the more instruments she controls the weaker her magic gets (reducing the durability and destructive power of her weapons).

Trivia

 * While Elizabeth herself was born into the country of Hungary, many of her family members were important political figures in Transylvania (she was a granddaughter of a voivode of Transylvania and the niece of the current Prince of Transylvania). This fact may be the reason why she was said to have been born from a prominent transylvanian family in the manga. The region of Transylvania is located in the country of Romania (both Romania and Hungary were part of the Kingdom of Hungary at the time).
 * According to historical documents, tales and rumors that Elizabeth Báthory had vampiric tendencies and that she bathed in the blood of virgins to retain her youth, were generally recorded years after her death and are considered unreliable. However, during the Walpurgis, Elizabeth references being accused of being a vampire, which implies that in the manga the rumors may not be completely wrong.
