Akatsuki Miyuki

Akatsuki Miyuki, or Kamijou Miyuki, is a character who appears in Toaru Majutsu no Index: Rebirth Testament. She is the main female character of the Child of God Arc and becomes a main supporting character for the remainder of the series. She is the descendant of the Child of God and because of this, she has the power to grant wishes. However, because of this power, Miyuki has been hunted by many people who seek to use her power for their own gain.

Appearance
Miyuki is a girl of around 12 with black hair tied in low pigtails, and golden-brown eyes. At some point however, her eyes changes from their golden brown color to a black (blue in anime), thus giving her the eye color of Kamijou Touma to prove they are now true siblings.

Personality & Character
Because of the tragedy she had witnessed in her life, and losing all of the people closest to her, Miyuki possessed a somewhat emotionless and detached demeanor, believing herself to be cursed with a power she did not understand. She believed that because of her nature as the Child of God, the gods themselves had forsaken and forced her to endure misfortune. Despite this, she did not hate the world or the gods and instead, blamed herself for all of the tragic events that happened to her, giving up on things like hope and giving into her own despair. This resulted in her using her power to subconsciously wish it away, believing it to be the source of all her problems. When she meets Kamijou Touma, her somber demeanor starts to change a bit, warming up to him from the kindness he showed her as he let her stay with him and Index. During her time as a member of the Kamijou Residence, she saw traits in him that reminded her a lot of Shirou, leading her to develop a familial attachment to him and saw him as an older brother figure. This was further enhanced when Touma had protected her from Bowen and Rosalia when they initially appeared, and then later when Romefeller Magician, Allan Pestage tried to capture her and kill Touma and the others. After the end of the incident, Miyuki decides to become the little sister of Touma, changing her surname to Kamijou and living with him, Index and Othinus for the foreseeable future. It is noted that when she declared this, her eyes changed from their brown color to a black, matching Touma's eye color and suggesting that her power as the Child of God may not have been completely banished.

Following her stay at the Kamijou Residence, she shows another side of her personality when she is around Touma, where she behaves like the young girl she actually is. These behaviors include wanting to be spoiled, like to wear animal onsies, and throwing a childish temper. On the other side of this development, as Touma gets into more incidents, she becomes worried for him greatly, fearing that there may come a time where he does not come home. This results in her making reckless actions that put her own life in danger, giving an indicator that she values the life of Touma and others more than she does her own life.

Biography
Miyuki was not originally born on Earth. She originally came from another dimension with a world very similar to earth's called Ryui. Five years before the current year, she lived a peaceful life with her parents and three older brothers in a countryside town. Her mother, Akatsuki Yume was a sage who was once a part of a cabal that worshiped children under the age of 6 as Gods. Sometime after meeting her husband, Akatsuki Kinzo, she gave birth to their daughter and fled the cult in order to live a peaceful life. As time went on, Miyuki accepted Kinzo and his three sons as her family and became very attached to them, particularly her eldest brother, Akatsuki Shirou. Their father had told them stories about the Multi-Universe, how there were many worlds and many gods who watched over all of them. He told her about Magic and that his wish was that Miyuki would one day be able to leave their small world and explore the Multiverse and everything it has to offer, but to know that even with all of the wonders of the cosmos, she is special and to never forget that. She took those words to heart and said that she will see the stars one day, but hoped that her family would be by her side. However, this wasn't meant to be. When she was 6 years old, the Grand Multi-Universe Empire had invaded Ryui, destroying multiple cities with orbital bombardments and razing the town that she lived in with ground troopers and droid officers.

Kinzo and Yume had decided to evacuate the planet via the ship that Kinzo had hidden. It was a ship that was able to travel to other worlds and he had already set the coordinates in the event something like this would happen. However, as they were on their way, they were found by the Grand General Esdeath and her Inquisitors. Kinzo urged his family to leave, resulting in Yume leading away their four children to the place where the ship was hidden. During the attack, Esdeath was able to mercilessly kill two of Kinzo's sons, resulting in him attacking her in a fit of rage. Yume urged Shirou to take Miyuki to the craft and leave, something that he did as Yume decided to stay behind to support her husband. As the battle went on, Esdeath eventually disarmed Kinzo and fatally wounded Yume, eventually leading to her death. Feeling as though there was nothing left to lose, he decided to use a spell that would have taken out Esdeath along with her inquisitors and himself, but this failed, as Esdeath was able to kill him before he could land a killing blow. But this was nothing more than a mere distraction in the end, as by the time Esdeath had killed Kinzo, his two surviving children had already left Ryui in a ship, which was also cloaked so it could not be detected and traced. Miyuki claims that this was the first day she had witnessed true evil, and it was because of this event that left a deep scar, though she was thankful to have her brother Shirou with her.

Some point after the Grand Empire's raid and destruction of Ryui, Shirou and Miyuki made it to Earth Prime where they spent the next five years living. Because of what happened to her homeworld, she became even more attached to her brother, who in turn swore to protect her from any harm that came to her. The two were taken in by an elderly couple, whose demeanor and mood reminded them of their late parents and peace returned to their lives for the next five years with Shirou training to become a powerful Magician, and using the teachings Kinzo passed onto him, including physical training. However, this peace was not to last. One year ago, the elderly man who acted as their grandfather passed away due to heart failure and in July of the current year (Around the same time as Index Old Testament Volume 1), the elderly woman soon passed as well, leaving the siblings to fend for themselves. Shirou however was able to care for the both of them, though the deaths of the people who adopted them hit them hard. Months later, another event would soon befall them when the Romefeller Foundation caught wind of the existence of the Akatsuki siblings and sent their men to bring them in, under the request of an unknown person. While the two were in the process of escaping, Shirou was struck and fatally wounded leaving Miyuki to panic and fear the worst. In an act of desperation, Shirou used the magic he learned from his father to transport Miyuki to Academy City, a place where he believed she would be safe and smiled before fainting. When Miyuki found herself in Academy City, she broke down, believing that everything she loved was now gone, feeling as though the Gods who watched over the Multiverse had forsaken her. Then, in a random event, she encountered a certain boy, one who was the same age as her brother Shirou.

The person who had contacted the Romefeller Foundation knew where she had been sent however, and had extended the contacts to another organization from a different world. Through the Romefeller, the Ministry of Science was contacted and told them that Akatsuki Miyuki was a person who held power to destroy the fabric of creation itself, referring to her power as the Child of God which seem to have disappeared sometime ago. Believing the Romefeller, the Ministry of Science sent their best operator, Bowen Chuuno, accompanied by the Sorceress Supreme, Rosalia Echidemont and sent them to Earth Prime, Japan, where they would head into Academy City to find her and bring her to them.

Powers & Abilities
Miyuki is a person known as The Child of God, a person who is closer to being one of the Fewer Than 20 Saints in earth Prime. Because of this, Miyuki has the power to grant wishes and alter fate itself, ranging from the wishes of others to her own wishes. However, because she was not trained on how to utilize her gifts, she cannot control them properly and instead, its usage is mostly done via subconsciously. So far, she has not used her power on a large scale, but it is believed that she is capable of affecting not only Earth Prime and the Phases, but the entire Multi-Universe as well, potentially putting her on the Level of a Magic God and even the Foreign Gods. Miyuki does not seem to be aware of the potential her power has and only knows that she has a gift and nothing more.

She resented her gift to the point where she used it to make her powers disappear, something that was confirmed when Rosalia used her Cosmos Eye to determine if she was truly the Child of God. After Rosalia's analysis, it was determined that Miyuki was just a regular girl, but this may not actually be the case. At the end of the Arc, Miyuki's brown eyes turn into a darker color, signifying that her power was merely suppressed, leading her and others to believe that her powers as the Child of God were truly gone. It appears that after deciding to become the sister of Kamijou Touma, her powers reactivated themselves to grant her wish, altering her genes to be that of the Kamijou Family, thus truly becoming Touma's younger sister.

Othinus warns Touma that w should other magicians including the Anglican Church find out about her origins and status, they may come after her to suppress her. Since everyone, including herself believe that she is no longer bound by that power, this fear of her being hunted has been dispelled. Though one can never be certain if she may become a target for other parties in the future.
