The Astil Manuscript or Sora, as affectionately named by Arata, is a legendary grimoire said to contain information about another world. Originally belonging to Hijiri, Sora has since contracted with Arata, supporting and protecting him after becoming a magus.
Sora has a very proud and cheerful personality, being enthusiastic in most situations regardless of any dangers. As such, she is quite straightforward and open, unafraid of speaking her thoughts. However, because of this, she can appear spontaneous and audacious, usually making suggestive comments or acting in a risque manner. Nevertheless, Sora is good natured and easy to get along with. In her first meeting with Arin, the two immediately became friendly with each other. Additionally, she can be quite shrewd and mischievous, finding amusement in observing and teasing those around her, especially of her master, Arata whom she enjoys for his upfronts and unpredictability. But despite her easygoing attitude, Sora is highly loyal and reliable to Arata and his friends, willing to fight and support them; although, she can be too lax on certain occasions. In those situations, she can become serious and determined, helping and watching over them numerous times. Nonetheless, Sora will remain obedient and devoted to her master, trusting in their decision and carrying out their requests. Before Hijiri's disappearance, she would follow her last order to grant Arata's last wish. Likewise, during the Royal Biblia school festival, she became suspicious of Anastasia-L, warning Arata of her and waiting for his choice.
Furthermore, Sora is exceptionally confident and proud of her own abilities as a grimoire, commonly proclaiming herself as a genius in spite of not quite understanding the process. Being Arata's grimoire, she has excellent teamwork skills, able to work together with him effectively and efficiently. During battles, she can become more focused, but rarely does she lose her composure. As such, she is still usually light hearted and nonchalant. However, she can sometimes become overconfident and reckless, leaving her open after using powerful attacks. Regardless, Sora is quick to recover to composure and decide on a proper course of action.
Notably, despite being a grimoire, Sora can become embarrassed in certain situations. When Astral Trinity erased her magic as well as stripping her naked, she expressed shock and disbelief that he would actually attack his own grimoire.
Sora's true form is a small, gray ornate book, bounded with chains. However, she has the ability to change her appearance, initially impersonating Hijiri until Arata discovered her deception. Since then, she has mainly used her human form to interact with others.
Human Form: In her usual human form, Sora appears as a young petite woman with long grey-white hair and a large black bow on top of her head. Her attire consists of a black strapless camisole with white stripes connected to a black choker with a metal ring, a red mini skirt with white clothes, black stockings, and brown loafers. Additionally, she also sports black arm sleeves held together with white bands, a black grommet belt, small black belts on both legs with the right one on the upper thigh and left one on her ankle.
Possessed by Hijiri since her birth, the Astil Manuscript was given the name "Sora" by her master. Together with the Ilias Fragment, their magic would make Hijiri stronger than even her parents. After Hijiri was assigned to observe Arata, Sora would help support her in repelling against demons that were attracted to Arata. Additionally, Hijiri would also sometimes task Sora with impersonating her while she was gone. However, due to her tendency to always attempt seducing Arata, Ilia would eventually become the one usually to disguise herself as Hijiri.
After Hijiri hears rumors of black shadows appearing throughout town, she and Sora leaves high school to investigate while Ilia poses as Hijiri. Using her master's rules, Sora discovers an area with magical activity. However, upon arriving at the location, the two find nothing until they suddenly witness a normal bystander disintegrate into black particles. Analyzing the cause, Sora tells Hijiri the results, as well as additional people disappearing.
Later, the two would continue to encounter the same situation as more people vanished into black shadows. Eventually, Sora determines that those disappearing did not possess any magical abilities, warning a reluctant Hijiri to leave the city or risk being absorbed as well. Sora also reveals that the incidents were most likely caused by Hijiri's connection with Arata as a result of her Thema and his Demon Lord magic awakening. Nevertheless, the grimoire complies with her master's decisions to save Arata at least. However, after Hijiri senses Ilia in distress, the two rushes to her location only to discover a drained Ilia in book form, as well as an unaware Arata whose magic abruptly expedites the Breakdown Phenomenon's destruction. In order to save Arata, Hijiri hands Sora to Arata, although Sora questions her master if she is certain. Hijiri affirms her decision, asking the Sora to grant her wish and save her cousin. Sora assents to her former master's last command, giving her farewell before contracting with confused and unaware Arata. As Hijiri ultimately disappears while Arata remained safe due to her magic, Sora and Arata suddenly find themselves in a void. A desperate and confused Arata then demands Sora to return his normal days, to which the grimoire obeys and creates an alternate world.
As a legendary grimoire said to contain information of another world, Sora has immense magical power, as well as a wide variety of abilities. Some noteworthy magic she has demonstrated are:
- World Reconstruction - Sora is capable of reconstructing an entire world by creating a separate dimension. First displayed after granting Arata's wish to bring back his normal days, she is able to freely control everything within her world, such as restoring a destroyed city and bringing the dead back to life, though it is all just an illusion.
- Polymorphism - Sora has the ability to transform or modify her appearance, usually between her grimoire and human form. However, she can also take on the form of others by projecting that person's shadow as long as he/she is alive.
- Magic Replication - After forming a contract with a master, Sora can replicate another Magus' magic by analyzing and modifying the magic for her master to use. Ironically, she was not fully aware of the process, stating that she did not need to understand because she was a genius. Currently, there are three steps:
- Concept - Grasping the basic concept of the magic or Thema. Her master must confirm both the name and execution with his/her own eyes and ears.
- Understanding - Understanding the foundations, the "genealogical tree" of the magic by learning the name of the magic's founder from a currently using Magus.
- Reasoning - Analyzing the magic's fundamentals and disassembling its chemical structure, which simply means dismantling the magic's "nature" through the use of logic. This can be done through her current master, Arata's stripping magic.
- Analysis - Adept at examining magic, Sora is able to quickly understand the nature of a magic and figure out a weakness.
- Sealing - Sora has also shown proficiency in sealing magic, objects, and even entities. Initially, she places a seal on Arata's magic in order to prevent him from causing a Breakdown Phenomenon. Furthermore, she was able to seal Lieselotte's Magic King Element, as well as revert Astral Trinity back to Arata.
- Telepathy - Sora can communicate telepathically with those around her openly or privately.
However, Sora's most notable trait is that she possesses her own will and thoughts, unlike normal grimoires, allowing her to act independently from her master. As such, she can either support her master by providing her magic to use or separately move on her own to give direct assistance. Nevertheless, Sora usually entrusts her master to make the final decisions. Considered an offensive type grimoire, Sora has a considerable amount of offensive power, easily able to destroy her surrounding and even large groups of enemies in one burst. But after a strong magical attack, she is prone to leaving an opening. She can also give her magic energy to Arata to replenish and augment himself. The magic she provides is even capable of protecting her master from being absorbed during a Breakdown Phenomenon. Her initial master, Hijiri, disappeared as a result of allowing Sora to form a contract with Arata as her magic would no longer sustainable while Arata survived the experience. Additionally, because she is not a biological being, Sora is essentially immortal and has lived a very long time. Notably, Sora's specialty is analysis and invocations.
During her time contracted to Hijiri, Sora would use her magic to support her former master's Chaotic Rune. For example, using rules placed by Hijiri in different locations, Sora can search for magical activities in a large area and project the position to her.
After Arata sacrificed his Demon Lord Factor and magic, Sora can no longer be utilized by her master with the exception of materializing her human form. Nevertheless, she still considers him to be her master.
- Scarlet Geburah - Summons a large magic circle that creates a powerful wave of destructive magic. Combined with Arata's "Meteor Punisher" and Mira's "White Universe", this spell is capable of destroying a Breakdown Phenomenon.
Arata Kasuga - Sora's current master, Sora first came to know of Arata during Hijiri, her previous master, Arata first became aware of Sora after she was entrusted to him by Hijiri to protect him from a Breakdown Phenomenon, as well as grant his wish before disappearing. Horrified, Arata would then demand Sora that she give him back his normal days, which she would fulfill while posing as Hijiri. After her deception was discovered, Sora has since continued to assist and protect Arata, eventually forming a contract with him allows him to use her magic.
Despite knowing each other for a relatively short time, the two quickly developed a close and trusting bond due to their similar easygoing and mischievous personalities. Sora, in particular, enjoys being with Arata's straightforward and perverted behavior, as well as finding her master both entertaining and interesting. As such, she is usually watching him or playing along with his antics. Nevertheless, Sora is very loyal and supportive of Arata, willing to follow his decisions and always looking out for his well being. Likewise, Arata has complete faith in her, relying on her strength in many different situations. Notably, in spite of her being a grimoire, Arata deeply cares for Sora and views her as a friend, rather than a tool. Her imprisonment by Ilia was one of the deciding factors that would cause Arata to change into Astral Trinity. Although, Sora would eventually return him to normal, stating that she preferred "the idiotic master". Additionally, Sora and Arata are also able to work together as a strong and effective team during battles, supporting and believing in one another.
Hijiri Kasuga - Hijiri is Sora's previous master for an unknown amount of time, originally being the one who gave the grimoire her current name. Prior to disappearing due to the Breakdown Phenomenon, Hijiri entrusted Sora to protect Arata and fulfill his wish, which she has since then faithfully continued to follow. Despite no longer being together, Sora would help Arata in his goal in finding her former master, confirming that Hijiri was still alive. Although the two would eventually reunite as enemies, neither one would hold a grudge against the other.
Ilia - Similar to Sora, Ilia was originally Hijiri's grimoire for an unknown amount of time prior to later joining Arata. During the Breakdown Phenomenon that destroyed Arata's hometown, the two would separate after Hijiri entrusted Sora to Arata while Ilia remained with her before disappearing. Later on, they would eventually reunite when Arata and Mira became trapped in Ilia's barrier while investigating the Royal Biblia Academy's destruction. Despite Ilia using Hijiri's appearance, Sora would immediately recognize her before subsequently confronting her in battle, treating each other in a rather friendly and calm manner regardless of being enemies. Ultimately, Sora would lose and become trapped by Ilia who intended to use her as a magic power source until Astral Trinity indirectly freed her.
After defecting to Arata, Ilia has since remained on friendly terms with Sora who, in particular, did not hold a grudge against her. Although, Ilia is usually bewildered by Sora's nonchalant and mischievous personality, whom the latter also often enjoys teasing her. Regardless, the two are actually quite close in spite of Ilia's denial. Sora once stated that they were close enough to never stop fighting. They both respect and understand the others abilities, allowing them to work together as an effective team to help support Arata.
Radix Astil - Originating from Radix, the two are considered to be "mother" and "daughter." After Arata forfeits his Demon Lord Element, Radix travels to Biblia in order to retrieve Sora, considering him unworthy of being her master in spite of her copy's opinion. However, Sora has been allowed by her mother to remain with Arata temporarily, until she is required for Radix's goal, to revive the true Demon Lord. Although Sora is hesitant about her mother's methods in trialing Arata, she is nontheless confident in her master's strength.
- Sora is capable of appearing as both her human and grimoire form at the same time.
- In the official Crunchyroll simulcast, Sora's grimoire form is called Astil Codex.
- Sora in Japanese means "sky".
