Tsunade Yukijirushi

"The touch of an infinite mystery passes over the trivial and the familiar, making it break out into ineffable music... The trees, the stars, and the blue hills ache with a meaning which can never be uttered in words."

- Tsunade to Seireitou Kawahiru

Tsunade Yukijirushi (綱手結城汁の市, Yukijirushi Tsunade), addressed by Sora as the Sorceress (魔女, yōjutsusha) is a spiritually-aware being of unknown origins who is an advisor to Takashi Sora. However, it was soon revealed that she was forced to be an advisor to him because of her strange powers. She possesses an ability to predict the future, as well as to reject phenomena.

Personality
Tsunade is a very quite and soft-spoken woman, yet retains a sense of zest and sarcastic demure. She is not above insulting Sora on multiple intervals, yet doing it in a manner that seems almost like complimenting. She seems to value peace, as she questioned Sora's actions reasoning of starting a war in Hueco Mundo. Tsunade also has shown a strong distaste for weakness or being overly dependent on other people. Being taken at a young age, Tsunade is often shown as very cold and apathetic. She doesn't believe in love or friendship, and doesn't particularly care for her own life. However, the last of those three descriptions can be easily rebuked, as shown when she begs for Seireitou and the Seijin Council's protection.

Stemming from her unusual powers, Tsunade has a firm belief in fate and destiny. She believes that nothing just happens; that there is a plan, and everything that can happen and will ever happen can be decoded by her powers. This can show hints of arrogance, something that Seireitou shows resentment for. Tsunade has been known to use her beauty to manipulate others, mostly men. She appears to have a somewhat twisted outlook with respect to this, often avoiding responsibility by claiming that people acted voluntarily when they were really coerced or manipulated by her.

Powers & Abilities
Limitless Spiritual Power: While the term limitless denotes that Tsunade has an ever-lasting amount of reiryoku, this is not true. However, despite it's almost frightening vastness, Tsunade is not able to access this of her own whim. Usually this power will only be released in times of anger, fright, or even when desiring to protect someone. Her spiritual power is shown to be of a tan color, but when using her mysterious powers, the color becomes lavender. Even though she has no real control of this monsterous power, its presence within her is evident. Despite being hit by a massive attack from Zacarias, she was seemingly unharmed.
 * Rejection of Phenomena: Tsunade has the power to reject fate by denying or undoing events in various forms. This power can be used for attack, defense, or healing. When being used, the color of this power is examplified by lavender. In Renge's words, she "violates the realm of the gods." Tsunade's mood directly influences the effectiveness of her powers. Feelings like doubt or worry make them weaker, while conviction makes them stronger. At their height, her powers resemble those of a deity in strength. It is this power that causes Sora to nickname her the Girl who surpasses God (神を超えた少女, Kami o Tsugu Shōjo).
 * Future Prediction: Sora explains that Tsunade possesses the power to hear the future. Tsunade can see events that transpire for up to several years, but only a fragment of it. Furthermore, she cannot see general visions; only when coming into contact with a certain person, can she see the fate that the future holds for that person.

Quotes

 * (To Seireitou) "Predicting the future... is like watching the ripples in the water. Some are born from the event, called fate, while others are simply continuations of the event, known as destiny. They are... like a chain, so to speak."

Behind the Scenes
Tsunade was designed to possess powers similar to Orihime Inoue's, due mainly because Aizen never wanted them, but merely used Orihime as bait for the Shinigami to enter Hueco Mundo. With Tsunade, Takashi Sora has true usage for her abilities, making her a more major character than Orihime.

She was inspired by Cassandra (カサンドラ, Κασσάνδρα; Greek for "she who entangles men), who was the daughter of King Priam and Queen Hecuba of Troy. Her beauty caused Apollo to grant her the gift of prophecy. In an alternative version, she spent a night at Apollo's temple, at which time the temple snakes licked her ears clean so that she was able to hear the future. This is a recurring theme in Greek mythology, though sometimes it brings an ability to understand the language of animals rather than an ability to know the future. However, when she did not return his love, Apollo placed a curse on her so that no one would ever believe her predictions. She is a figure both of the epic tradition and of tragedy, where her combination of deep understanding and powerlessness exemplify the tragic condition of humankind.
