Grace Synclavia

**Grace Synclavia** (グレイス・シンクラヴィア, *Gureisu Shinkuravia*) is the current empress of Vatlantis as well as the younger sister of Aine. Having to inherit the throne of the Valtantis Empire at a young age during the time of Genesis's breakdown, Grace became the tyrannical Empress of Valtantis. She was partly responsible for all suffering on Lemuria and a main antagonist of the Vatlantis Arc until her defeat. Afterward, she worked together with her older sister and the people of Ataraxia in order to save both of their worlds from the gods, which they succeed. After the end of the war with Deus Ex Machina, she forcefully removes her sister from the throne so she could be happy with Kizuna on Earth.

## Appearance

Grace has pink hair with patching pink eyes. She wears two flowers on the side of her head. While she greatly resembles her older sister Aine, Grace is slightly shorter than Aine and has a smaller bust and small but well-formed buttocks.

Grace's usual "outfit" is a few white and gold accessories which barely hide her breasts and crotch also her butt is exposed without any fabric to cover it. When she was a student on Ataraxia, she wore the school uniform.

Although she only appeared for a few seconds in the final episode of the anime, her appearance is more "mature" than the light novel illustration.

She somewhat resembles Silvia Silkcut.

## Personality

Grace has a very short temper and is quick to anger. This is shown by the hatred she exhibits for Kizuna, seeing him as the "Demon King of Lemuria" who took her sister, Aine, away from her, and the one person Aine may care about more than her. Her quickness to anger is seen as her largest flaw by enemies and allies alike, as it is very difficult to calm her (except Aine), and her magical power and prowess is reason enough to fear her.

Despite this, she dearly loves her sister Aine, and was very happy upon her return. She gladly gave the throne back to her , who is the rightful heir, and the true Emperor. However, she still holds a great deal of power, holding on to it as she sees her sister as unable to make proper decisions (due to her relationship with Kizuna and her wish to not become his enemy). Despite this, she does recognize Aine as Empress and acts to support her.

However, after being saved and conquered by Kizuna she ended up falling in love with him. This resulted in her fantasy and goal to wed herself and Aine to Kizuna and make him become the first new Emperor. She has since started treating Kizuna as her big brother, calling him Nii-sama and showing affection around him.

    . While a student on the Ataraxia, Grace personality became more cheerful, friendly and somewhat immature for her age. This is most likely what she would have been like if she didn't have to carry the responsibility of being the empress at a young age. Even after remembering that she is supposed to be an empress, she still maintains her cheerfulness. However, after being forced to remember all the horrible things she did by machine god Osiris, Grace started feeling guilty about everything she did. While she thought that she would have to take responsibility by committing suicide, Kizuna convinced her that wasn't the right answer. Instead, he persuaded her to help save the people of Lemuria from the Deus Ex Machina as a way to make up for everything she did.

After defeating the Deus Ex Machina and saving both worlds, Grace's became more selfless than before. This was displayed when she decided to start a coup d'état for the throne and banished her older sister from Valtantis as a way to make her go with Kizuna. Grace wanted her to be happy with the man she loves, instead of enduring her sadness to stay with her.

After learning Gravel would bear one of Kizuna's children, she planned to take an auntie's role towards Gravels daughter. When she found out Zelshione had given birth to Kizuna's son, she felt a great deal of maternal love towards him and wanted to help him grow into a magnificent warrior like his father.

## History

### Background

Grace is the Empress of the largest nation in Atlantis, known by humans as the AU, the Vatlantis Empire, which rules over most of the world. She is second in line to the throne, and has been acting as Emperor in Aine's absence.

## Skills and Abilities

* **Keen Intelligence:** Despite her age, Grace is very intelligent and smart, as she shows during her reign as the emperor of Vatlanitis. During her time on Ataraxia, she skipped a grade due to her good grades in school.
* **Master Combatant:** Despite being an emperor and being guarded by the Royal Guard most of the time, Grace is a skilled fighter. She is capable of holding her own against both her older sister and Kizuna at the same time, although they were only trying to stop her rather than beat her. She even beat Lunora, the Death God of the Coliseum and the strongest member of Quartum, without using Koros energy absorbing abilities. Her combat prowess is such that she was chosen as a candidate to battle with Thanatos.
* **Master Scythe Wielder:** Grace is an extremely proficient scythe user, able to destroy magic weapons and armor with one or a few strikes.

## Equipment

**Heart Hybrid Gear:** **Koros**. As the Empress, Grace wields one of the most powerful Heart Hybrid Gears on Atlantis, and her skill in using it is the cause of fear by her enemies and her allies, as its power can cause great destruction. This Heart Hybrid Gear is extremely powerful, and Grace's power in it is enough to destroy an entire room in Zeltis' (capital city) castle by merely releasing her magical energy to full power.

* **Scythe:** Koros' signature weapon is a large scythe, which is very powerful and able to inflict large damage to, or defeat/destroy other Heart Hybrid Gears or magical weapons in a single slash. Each scythe possesses different sharpness and toughness.
* **Harvest:** This is Koros's special ability, which enables the wearer to suck the magical power out of other Heart Hybrid Gears, and use it to replenish the pilot's own. Well powerful, Grace has a limit on how much she can absorb.
* **Immense Speed:** Grace can move and react at high speeds, even keeping up with Aine and Kizuna (in Mode Zeros) with ease.

## Trivia

* Although she only appears for a few seconds during the final episode of the first season of the anime, her physical design may be more "mature" than in the light novel.
* While a student on Ataraxia, Grace was able to skip a grade and was in the same class as Kizuna. She also went by as **Grace Synclavia Chidorigafuchi**, the same surname her older sister had while on the Earth.
* Although at the beginning Grace hated Kizuna, she later came to desire him to the point of masturbating while thinking about him in volume 11.
* In volume 14 Grace thinks of Zelshione's son as her future partner. She believes that 15 years of difference isn't uncommon.
