Arata Kasuga

Arata Kasuga is the Magic King of the Superbia archive and main protagonist of the series, possessing the ability to nullify and copy magic. After a Breakdown Phenomenon destroys his hometown and causes his cousin Hijiri to disappear, Arata becomes determined to save her by becoming a Magus and transferring to the Royal Bibilia Academy where he fatefully meets the Trinity Seven.

Personality
Arata has a carefree and cheerful personality most of the time, usually cracking jokes and teasing others even in dangerous situations. He is also noted to be very perverted, often finding himself in risque situations or confessing his desires towards a girl. Usually this is by complete accident, but he simply rolls with it, and lets himself enjoy the situation without getting worked up about it. During these situations, he usually quotes: "Thanks you for the treat" or something to that effect. This often earns him a scolding from Lilith and scorn from Mira Yamana, the Top Seat of Grimoire Security, who calls him filthy or impure. Other girls such as Revi, Akio, or Liselotte don't particularly mind and often goes along with his remarks. However, he knows where to draw the line, as he refuses a kiss from Yui because that is only for "when we're closer". In times of need, Arata can become very dependable. Arata is very calm under pressure, in both perverted and dangerous situations. His natural way of thinking allows him to make rational decisions and develop solutions to problems that otherwise others would panic to. Arata cares very deeply for others, especially his friends. He is willing to risk his life and become stronger to save those he cares about, such as Yui, Lillith, Liselotte, etc.

There are two known instances that can cause Arata to lose his cool. The first is Kasuga Hijiri, who is his entire motivation for becoming a magician and his driving force for most of the story. Lieselotte was able to shake him mentally by offering information on her whereabouts, and when the two of them finally do meet he single-mindedly tries to take her back. The other is someone disappearing due to his own powerlessness, a trauma developed by Hijiris apparent "death". The first time this happens, he triggers Astral Trinity's awakening to prevent it.

As Astral Trinity much of his personality becomes quite different from before. Unlike Arata, Astral Trinity is cold, ruthless and arrogant. He would intentionally go so far as to erase the magic of his Grimoire if she tries to attack him and is visibly more assertive, demanding, and forceful when dealing with the things he wants. In one instance, he told Mira that she was worthy of him, demanded that she submit to him, and was clearly very shocked when she slapped him in response. Astral Trinity also seems more serious than Arata, although he can still be seen as rather carefree and whimsical. He is also something of a show off, summoning and manipulating a Breakdown Phenomenon to face off against foes, even when he clearly didn't need to.

During the Sky Library Arc, Arata admits that the Trinity Seven are nearly as important to him as Hijiri is, showcased by one of his very rare shows of anger towards Abyss Trinity  for hurting Akio.

Appearance
Arata is a slender young man, with shaggy cut dark hair, and bright red eyes. Initially, Arata usually wore his first high school uniform, the top half consisting of a black t-shirt, worn over by a white dress shirt and an unbuttoned black gakuran jacket. The bottom half was a simple black pants and penny loafers.

When he transferred to the Biblia Magic Academy, he mainly started wearing the Academy's uniform, which also consisted of a white dress shirt, black t-shirt underneath, penny loafers, dark suit jacket with the school symbol on the breast pocket, and pants. However, he now includes a vest over the dress shirt and and a red tie. Normally, he was the dress shirt top button unbuttoned and untucked with the tie loosened. In casual attire, he wears a looser variation of his school attire. Arata also usually wears his grimoires in the fashion of a necklace or tied around his hand.

Currently, Arata received the mark of the Magic King on his right hand after obtaining Judecca and learning three different archives despite not fully mastering Acedia.

Magus Mode: Originally, Arata wore a black mandarin collared shirt, a jacket with ruffled sleeves, dark pants and shoes, with a white sarong. After copying Akio's Mantra Enchantment magic, his Magus mode changed to a white mandarin collared sleeveless shirt, worn over by a black sleeveless stand up collared jacket. The bottom half consists of white pants wrapped around by a sarong and tied with an abrasive belt.

Trinity Form: Signifying that he has become a true magic king, Arata's attire in this form includes a white long-sleeved shirt, under a shoulder cape and collared vest with arm gloves. He also wears again white pants with knee length boots, wrapped around with a waist-cloth, sarong and belt. The shoulder cape, vest, sarong, waist-cloth, booths and arm gloves have a black with white edges or cuffs design.

Superbia -  Imperium
Arata's Thema is Imperium or "Rule" from the Superbia Archive, meaning that his magic is used to dominate and "rule" other. Arata's primary magical ability is dispelling other magic, often with the result of stripping any nearby victim's clothes, thus earning the nickname of "Stripping Magic". This magic is also capable of easily dispersing many Breakdown Phenomenons. Recently, he has learned to adjust the level to avoid stripping every piece of clothes. As a Magic King Candidate, as well as possessing the Astil Manuscript and later the Ilias Fragment, Arata is awarded numerous powerful abilities. One of which is the ability to copy other Magus' magic, even those from different Archives and Themas. Simply his grimoires rearranges another magic into something Arata can use. This process to copy another's magic has three steps:
 * 1) "Concept" - Grasping the basic concept of the magic or Thema. Arata must confirm both the name and execution with his own eyes and ears.
 * 2) "Understanding" - Understanding the foundations, the "genealogical tree" of the magic by learning the name of the magic's founder from a currently using Magus.
 * 3) "Reasoning" - Analyzing the magic's fundamentals and disassembling it's chemical structure, which simply means dismantling the magic's "nature" through the use of logic. This is done through Arata's stripping magic.

When all three steps are completed, Arata is then able to use that magic with his own twist. Currently, he as copied three different magic:


 * Akata_Gula_Mode.png Alchemic: The first magic he copied was Lilith's Abies Thema or "Outer Alchemic" from the Luxeria Archive, allowing him to use alchemy to form guns and firearms as she does. He uses this to direct his Anti-Magic abilities rather than throwing them randomly at everything in his vicinity. Using this directed version of his magic, he defeated a D-type demon dragon and dispersed his second Breakdown Phenomenon.


 * Mantra Enchantment: The second magic Arata learned was Akio's Fides Thema or "Mantra Enchantment", which gifts him the ability to enhance his body for defensive or offensive use, namely he manifests a dragon-like entity based on the D-type demon he had defeated before. Using this magic requires him to have a very strong determination.


 * Logos Art: The third magic Arata completes was Liese's Stagna Thema or "Logos Arts", which grants him the ability to manipulate time. He is able to transport himself small distances and momentarily freeze time for a moment. Currently, he has not fully mastered Logos Arts, which has caused his magic to become unstable.

Arata fulfillment of the Trinity (mastering three Themas and three Archives) grants him the ability to use the Magic King weapon, the Black Imperial Sword Judecca. Along with his Imperium Thema of the Superbia Archive, he becomes a "real" magic king, gaining the Trinity Form and even performing Paladin level techniques. However, this has caused the magic king element to eat away at him, causing him to feel pain and hallucinate. As he continues to use his magic, he is slowly closer to becoming Astral Trinity.

When Arata's magic goes out of control, he forms a very powerful Breakdown Phenomenon. A black sun appears in the sky above and proceeds to reduce everything below into base particles which it then absorbs, effectively wiping out a city in the first incident of its manifestation.

Techniques
Outer Alchemic
 * Meteo Punisher - Using a gun, Arata can shoot a large blast of anti-magic towards a directed path. This attack is capable of erasing a Breakdown Phenomenon.
 * L'Ciel Cocytus - Wielding Judecca, Arata performs a enormous slash, even capable of destroying Sky Library.

Mantra Enchantment
 * Realize - Activating a macro in the Astil Manuscript, Arata can use Outer Alchemic to create a weapon such as a handgun or rifle.
 * Conception - Taught to him by Akio, Arata uses his determination to create a single magic character on any part of his body, usually on his fists, chest or forehead. This spell will strengthen the body part the magic character is on, giving him defense against most physical attacks. Furthermore, he manifests and freely control a dragon-like entity, based on the D-type demon during Yui's Breakdown Phenomenon. This dragon is capable of nullifying any magic.

Logos Art Combination
 * Chrono Calculation - This spell allows him to teleport short distances.


 * Meteo Dragonar - Activating the Outer Alchemic spell Realize and Mantra Enchanment spell Conception at the same time, Arata creates a rifles and shoots a large burst of anti-magic in the form of a dragon. This attack is capable of dispersing a Breakdown Phenomenon.

Astral Trinity
The "True Magic King" is Astral Trinity, who resides within Arata. When placed into a situation of particular stress or danger Arata undergoes the change into this being. Astral Trinity possesses all the same powers as Arata, Specifically his power to "Rule", however the sheer scale and malice behind their uses of this power is considerably greater in the case of Astral Trinity. He can direct his Anti-magic ability with simple gestures, defeating two grimoires and Mira, a specialist in deflecting all magics used against her, with overwhelming ease. He can manifest and control the "Black Sun" Breakdown Phenomenon just as easily, effectively destroying an entire sealed dimension in moments. It has also been implied that Astral Trinity is capable of some form of hypnosis as Hijiri noted he will someday "suppress" the Trinity Seven.

Hijiri noted that Astral Trinity, the Magic King's, purpose is to unite the Trinity Seven and destroy the world with them, effectively hinting at the sheer enormity of his power.

Grimoires

 * Astil_Manuscript.pngAstil Manuscript - A legendary grimoire that once belonged to Hijiri, the Astil Manuscript has since contracted with Arata once he became a Magus. Said to contain "information from another world", the grimoire is able to perform numerous magic, giving Arata a great deal of abilities. Originally, she was capable of granting Arata's wish of returning to his normal days by restoring his destroyed hometown and inhabitants in an alternate dimension. After undertaking with him, Arata received the ability to copy other people's magic, under the right conditions, even from different Archives and Themas. This is possible through the Astil Manuscript modifying the magic in way that Arata can use it. Furthermore, having it's own will, the Manuscript can also take on a multiple forms, transforming into Hijiri or her true appearance, Sora. As Sora, she is able to act independently from Arata, performing her own magic which allows her to support Arata externally. When he becomes Astral Trinity, she was able to revert him back to normal.
 * Illias Fragment - Another legendary grimoire, the Illias Fragment also originally belonged to Hijiri before joining Arata. Like the Astil Manuscript, she shares many numerous abilities such as transformation, world construction, magic analysis, etc. She was also capable of controlling a group spectres and even managed to trap Sora. Described as a "support type grimoire", she mainly assists Arata through increasing his offensive power, stabilizing his magic and healing any wounds. LIke Sora, she is able to transform into different forms such as Hijiri, who she often took her place when Hijiri had to leave to magic business, or her true appearance as Illya. In her human form, Illya is also able to act seperately and support Arata with her magic externally as well.

Weapons

 * Black Imperial Sword Judecca - a Magic King weapon originally sealed away in the Sky Library to be used against the Magic King, Arata would ironically release the sword and become it's master. Also having a will of it's own, usage of Judecca required the user to have the Trinity, which Arata initially failed and almost forcefully reverted back to Astral Trinity again. Eventually, he would surpass the requirements by mastering four Archives, and become owner of the weapon. With his acquisition of Judecaa, Arata's magic increases tremendously, allowing him to fight on par with powerful opponents. The sword also allows him to use multiple magics from he copied at the same time to perform even Paladin level techniques. Judecca is also capable of changing it's appearance, shrinking into a smaller version of itself as well as an unknown human form.

Outer Alchemic

 * Handgun
 * Shotgun
