Saya

Saya is the younger sister of Ragna the Bloodedge and Jin Kisaragi. She was kidnapped by Yuuki Terumi and became the vessel for Izanami. She was the basis for the Murakumo Units, specifically Lambda-11, Mu-12, and Nu-13.

Appearance
As a young girl, Saya had shoulder length blonde hair and large green eyes. She has fair skin, and was often seen wearing a plain, white strapped dress.

After having her body surrendered to Hades Izanami, Saya’s appearance took a hugely drastic change. Aside from the differences attributed to age, Saya’s hair took on royal purple hue that reaches down to her lower back; her eyes also changed from green to a crimson red with many black circles layering them. Her attire became much more like an empress as she now wears an elegant golden headdress with a golden band to keep her hair in place. As Izanami, Saya wears a white kimono with elongated sleeves, and a red and yellow skirt that reaches down to her feet. Around her waist she wears a cyan bow while also wearing a black cape over her entire body; said cape has multiple purple bands reaching around her figure, complementing the royal attire.

Personality
When she was a child, Saya was kind and loving towards her siblings, and showed affection to the Sister despite the short time they spent together. These feelings remain untainted by Izanami’s possession, as they still exist for Ragna, although little else is shown of what she is like.

Evergreen Eyes
The earliest known information about Saya is that she was in a laboratory controlled by Relius Clover with her siblings Ragna and Jin. Her "mother" was the 5th Prime Field Device, and was saved from the lab by Jubei, who took her and her and siblings into the care of Celica A. Mercury, the Sister.

Two weeks after having arrived in the Sister’s care, the children went to find strawberries to make into jam alongside the nun. Here they learned that she had no sense of direction, which lead to them getting lost in dense woodlands. The journey’s length took its toll on Saya, and she retired herself to being carried by Ragna across the forest; as time passed, she took notice of a creature in the background, but was told to ignore it.

After the group found the strawberries, Saya volunteered to help the Sister create the jam while the boys laid the table. What she produced was more akin to blackened sludge than jam, but nonetheless, Ragna ate it – he was knocked unconscious.

The children would live happily in the church until Yuuki Terumi managed to find Saya close to the edge of the church’s barrier. He handed her the Mucro Algesco: Yukianesa to pass to Jin. On March 1st, 2192, Saya obliged under Terumi’s influence, which lead to the barrier collapsing as a result – the Sister was murdered, Ragna’s right arm was cut off, and Jin and herself were kidnapped by Terumi and Relius. Saya was kept by the duo, becoming the basis for the Boundary Interface Prime Field Devices Lambda-11, Mu-12, and Nu-13 after having been viciously tortured by Hazama in his pursuit to understand pain. At some point, Saya became the Imperator of the Novus Orbis Librarium, and would also become the vessel for Hades Izanami, leading to her laying in slumber for an unknown amount of time.

Continuum Shift
Saya, now possessed by Hades Izanami, awakened at the end of the Continuum Shift phenomenon event. She seized Takamagahara with the assistance of Nine the Phantom, Hazama, and Terumi, shortly encountering her siblings and Noel Vermillion afterwards. Despite the reunion, it was kept short as Izanami took little interest in any of her foes.

Chrono Phantasma
Still under the influence of Hades Izanami, Saya’s feelings towards her family still remained unchanged, as even Izanami admitted that her attachment towards Ragna was proving to be a nuisance to keep under control. Despite this, she still remained under Izanami’s firm control – even her body had changed as it was not affected by Hakumen’s time killer technique, which would kill most mortals.

Powers and Abilities
Saya has an incredible amount of Ars Magus aptitude, which is the suggested reason that she was placed in the Sister’s care. Also, her body has the unique ability to near-infinitely amplify seithr. Additionally, Saya’s willpower is extraordinary as her emotions remain to struggle against Izanami’s control despite the time spent in her current state.

As of Izanami’s possession, Saya now has untold power and is immortal to a technique which strips opponents of the time they have left in the world. Combined with the little-to-no effects present on her while wielding the Gigant: Take-Mikazuchi.

Saya
''Ragna and Jin's younger sister, who also happens to be Imperator of the NOL. She's physically weak, but her aptitude for Ars Magus is beyond compare. She was raised by the Sister in an area that had little seithr.''

After being discovered by Yuuki Terumi, she is turned into the basis for Boundary Interface Prime Field Devices.
