Personality: Usually very quiet and reserved, Ester can either be extremely graceful, or highly uncoordinated. When not in conflict, she is very quiet and constantly uses the term -sama to everyone, not just her superiors. In the event of a fight, she shows her true emotions and is a raging mass of malice, allowing her power to explode. Though she swings her sword madly, she claims to have learned something from every battle. Ester, though she may not seem it, actually is very calculating of others, easily determing which persons will become a threat to her later. It is her idea to crush people before they are allowed to gain their full potential if she believes they may undermine her, or turn on her. Otherwise, she might help them strengthen, and use them for fights when she is bored. She enjoys fights to the death, seeking out strong enemies and defeating them utterly is the only way she knows how to fight.
   Likes: Ester enjoys poetry and watching others from afar. Though she remains unknown to most Espada, she has made it a habit to watch high ranking espada from far away. Besides this, she enjoys eating most food. Her favorite pass-time is sword fighting with other arrancar. Secretly, she enjoys watching human television and is known to have a hideout in the human world where she goes to watch television and read dirty magazines. Rarely, she can be found at her hideout with human books piled around her, reading about fantasy worlds. She likes to write short stories about the characters in the books she reads. She calls the collection of her stories 'Heartnet,' due to her favorite character in a book series she has read.  
   Dislikes: Ester dislikes being given orders by those she personally deems inferior, such as the Gillian class arrancar. Ester also dislikes seeing hollows devouring each other, as it reminds her of her past as a hollow. She dislikes poachers and animal cruelty, and she feels that those who do not respect the refined arts do not deserve to live. Ester dislikes people who are not confident in their ability to win, even if she believes they cannot. She also has a hatred for women who hold a higher title or rank than herself. Ester hates the taste of any soul who's spiritual power is lower than a gillian and refuses to eat their souls to substain herself, prefering to go hungry.
   Motivations: The driving force behind Ester is that she hopes to prove useful to First Espada one day, hence why she constantly strengthens herself. Another driving motive is her desire to defeat current Zero Espada and make him obey her. She plans to be able to find a way to once again be human, even if it means getting rid of her arrancar abilities or having to fight the First. Once she becomes human, she wants to live a happy life and perhaps even go to Soul Society after her death. If she cannot, she plans to continue gaining power until she is on par with the Vasto Lordes in terms of strength. As such, she constantly improves herself, hoping her strength can help her become either a human, or the strongest hollow.
   Fears: Ester has a deep fear of females, stemmed from her defeat by a very powerful female hollow when she was a adjuchas. As such, she attempts to place herself as far from females as possible, even abandoning a fight if one appears. Yet, if a female outright calls her weak, she engages them in blind fury. However, this doesn't stop her from admiring them from a distance. She also fears being weak, to the point she'd rather die of exhaustion than admit defeat. Ester has a fear of arachnids, due to their multitude of legs and their poisonous venom. Her fear of spiders makes her a neat freak, to avoid any reason for spiders to come into her rooms. She finds them to be creepy and will make up excuses to leave the room one is in.
   Special Characteristics: Ester's Zanpakuto is black, and the length of her spine. The blade is very narrow and slim, yet has enough hardness to easily smash through steel and rocks. However, her blade has no actual edge. Ester reserves her Resurrección for enemies she wishes to utterly defeat and eliminate completely. Ester claims that she can fire ceros from any appendage, and that she can use the Gran Rey Cero. This is unknown, as she relies almost exclusively on her sword. Ester has one scar on her legs for every hollow and arrancar she has ever fought, including the ones from when she was just a hollow herself. Most are self-inflicted.
