Saya

Saya is the current Imperator of the Novus Orbis Librarium, as well as the younger sister of Jin Kisaragi and Ragna the Bloodedge.

Information
Saya was born with a frail body, and throughout her life, she was bullied by her brother Jin. Her other brother, Ragna, was much more caring, spent much time with her. Jin grew jealous of the relationship Ragna and Saya shared, and eventually attempted to kill her, immediately after she gave Jin the Nox Nyctores, Yukianesa. She was kidnapped by Yūki Terumi the same night, and was given unconscious to Relius Clover. According to the Drama CD The Wheel of Fortune, Relius and Terumi were planning to use her body as a "Vessel" for something. However, what was sealed inside her is unknown to date.

Noel Vermillion/Mu-12, Lambda-11 and Nu-13, as well as the unseen prime field devices 1-10, are all copies of her, sharing her physical traits, but none of her memories. However, the reason of why she is the basis has yet to be explained. During BlazBlue: Continuum Shift, it is revealed that Saya had been alive throughout the years, and is currently the Imperator of the NOL, while Hazama and Relius work directly under her.

Since the day of her kidnapping, her appearance has changed vastly. She now has red eyes and long, purple hair. It is also interesting to note that she doesn't seem to have aged at all. Also, her personality is completely different, like she is not acting like herself, and she speaks in an archaic tone. As Imperator, she rules the world and goes by the name "Imperator Librarius".

While Ragna sacrifices his left arm to turn Mu-12 back into Noel, Saya destroys the Master Unit, Amaterasu, while nobody's looking, and takes control of Takamagahara, thus granting herself the one wish she had always wanted: to prevent time from looping any longer and make the world the way she believes it should be: a "World of Death" where death is permanent, and when things end once, they shall end permanently. The reunion with her brothers was vague, as she didn't direct a word at either of them.

In The Wheel of Fortune Drama CD, which shows the timeline where Noel did not exist, it was revealed that Jin and Saya were very affectionate towards each other when they were young. They were happily playing together, and Jin's attitude towards Saya was completely different from the current timeline. Saya gave Jin a crown of flowers she had made, and said that she loves Jin very much. This is seen through a vision by Tsubaki Yayoi, and she immediately displayed jealousy towards Saya, screaming at her to get away from Jin.

Powers and Abilities
While she hasn't show any ability yet, The Material Collection mentions that she has incredibly high Armagus aptitudes.

Appearance
Saya is a young woman with very long, purple hair tied into a ponytail, and soulless red eyes. She wears a white and red Japanese-style outfit reminiscent of an empress, tied with a light blue sash, with a golden crown and a dark cape over her shoulders.

When she was a child, she had medium-length blonde hair, green eyes, and wore a white dress.

Personality
While she has only been seen in one scene, it is clear that over the years Saya has become devoid of all emotion and extremely literal-minded. The cause of this is unclear, but it is suggested by other works in the series that this not actually Saya's real consciousness, but rather something that is using her as a "vessel".

Cutscenes shown in Ragna's story show that Saya was very dependent on her brother when she was little, and was a normal and confident young girl. However, this changed very soon after her kidnapping. Her speech has become that of a stoic, yet cynical woman who looks down upon others.

Trivia

 * Saya can be said to be the BlazBlue counterpart of Guilty Gear's That Man. Both are very mysterious characters that age abnormally (Saya does not seem to have aged much, if at all, since the day she was kidnapped whereas That Man ages backwards). Both wield immense power that far surpasses that of the main protagonist, and they have numerous servants which includes some of the playable characters. Concerning their two main servants; Both have one that is calm and collected (Relius/Raven) and another who is wild and destructive (Terumi/I-No). They also share a close history with the main protagonist(Sol/Ragna) and are never directly fought in the storyline.
 * Saya's voice actresses (for when she is a child) in both the Japanese and English dub has the most characters that is voiced by her, those being Noel, Mu, Nu, Lambda, and Saya herself.
 * In The Wheel of Fortune Drama CD, Terumi brought an unconscious Saya to Relius just after he burned down the church, while Relius commented that her body will be useful for a "vessel", implying that her role at the end Continuum Shift's true ending might be linked to possession, and not her actual consciousness. This is even foreshadowed by Rachel in her own bad ending, where she isn´t surprised to see Saya at all, asking her if she has finally "awakened".
 * Given some cryptic comments made about her by Rachel and Takamagahara, it is possible that the entity possessing Saya is the first Boundary Interface, which gained a soul and the power of the Eye while in the Boundary and was subsequently sealed there.
 * The Material Collection mentions that Saya has incredibly high Ars Armagus aptitudes, and the reason she was raised in the church was to hide her from Terumi. This may imply that Terumi already tried to capture her sometime in the past.
 * For reasons unknown, her Japanese voice was redubbed for the release of Extend, possibly due to the fact that Kanako Kondo's performance sounded almost exactly like Noel and Mu. When Saya is revealed, she clearly looks older.
 * Coincidentally, both Yukana and Kate Higgins are the voices of C.C. in the anime Code Geass, and Saya appears to have some similar qualities to the character.
