Bio: As a human girl in 531, life was hard as she was a traveling spirit hunter with her father. She never asked for such a life, but tried to make the best of it. Every successful hunt brought a smile to the people, and that made her day -- her life put in jeopardy -- somewhat worth it. She's been at it since she was 5. One day, when she was camping in the night, she and her father got assaulted by a band of ghouls. The father was killed at the camp and the daughter was taken captive to an abandoned blacksmith shop. They chained her wrists and ankles up and tortured her every day, calling her a cruel b*tch for the mass murder of their kind. One day, she's had enough. Not just of the torture, but of everything. Of the business that was forced onto her, the many times she's had to put her life on the line, she just couldn't take it. So she got an idea. She wrapped a chain around her neck, choking herself out. She was angry. Angry at this world, angry at the ghouls, at her father. She wasn't trying to kill herself.
She was going to become one of them.
The rage that was pent up was so intense the the transformation on death created a shock wave. The other ghouls rushed in to see a ghoul whose skull was already so smooth the teeth were actually merged. They transformed into their ghoul forms and tried to fight back, but they were no match against the new ghoul's iron power. She managed to encase them in iron maidens. She ruthlessly began summoning spikes on the iron maiden, killing the ghouls, as hard as it is to do so. She began to go around the world, proceeding in the killing of all ghouls. She eventually moved on to hunt ghouls in the United States once it was established. She made a name for herself by doing this. One day, while going on a short trip around the world, she found a scythe named Salvador at the bottom of a lake, wrapped in cloth and chained with a complex lock system. But being an iron ghoul, she released it with ease. This scythe was the only weapon that could kill a ghoul as if it were human. She made this her primary weapon. As the years went on, she learned all of its secrets. Including the secret activation code that only the creator and Grezcht knew. With that scythe, she became known as a hero, the Ghoul Slayer Ghoul.
However, this is a problem. Now that the elden days are over, there have been less and less malevolent ghouls, excluding Ystmurra. It's not uncommon that an innocent ghoul would get slaughtered because of prejudice. She is the only direct threat to Ystmurra in the Ghoul's Paradise character roster.
Personality: Kind and eccentric towards humans, cruel and cynical towards ghouls, overall snarky and condescending.
Skill: Can retain her human form by the mere action of killing a ghoul and stealing part of its soul. No matter how old she is or may get, as long as she kills ghouls, her human form is as perfect as a plum.
Other: Her weapon, Salvador, was previously held by Grezcht in his earlier days up until the day he fought Ystmurra and Zeilyph. He lost the scythe to Ystmurra and Ystmurra sunk the scythe to the bottom of a lake. Merrikhyl found it after a long time and weld it.she dug into its secrets and not only found out its power against ghouls but the one thing that, of the many holders of the scythe, only the creator and Grezcht knew: how to unleash its power, Salvador De Los Muertos Vivientes.
All finished! Thoughts?
