Arin Kannazuki

Arin Kannazuki is the Trinity Seven of the Ira archive and a user of Chaotic Rune magic, whose appearance is strikingly similar to Arata's childhood friend Hijiri. Furthermore, she is also the Magic King's partner, becoming an early ally and later close friend to Arata.

Personality
Arin is quite blase, typically only having a serious or blank expression and rarely showing any other emotions. Because of this, many of her actions and expressions usually do not match. Furthermore, Arin has often been shown to be blunt and lack a common sense, generally never reacting the same way most people do in many situations. For example, Arin on one occasion chose to bath in the male bathroom because she preferred the quiet. Even when Arata discovered her naked by chance, she barely showed any reactions and acted nonchalant despite his presence. Often times, others have to correct and chide her for her behavior, which she usually finds difficult. However, despite her lack of expression, Arin is not quite a cold as she appears to be. In actuality, she can be kind and caring, even if she does not show that often. Arin gets along very well with her friends, caring for their safety and willing to fight for them. She has also been shown to be perceptive, once immediately noticing Mira's change of attitude toward's Arata.

Notably, after meeting her partner Arata, Arin has changed, showing a wider range of emotions. Prior to his arrival, Arin was solely focused on her research. Since then, others have stated that she has become less emotionless which they enjoy this side of her more. In particular, she has become very devoted towards Arata, even willing to do perverted acts with him. In addition, she is also concerned for his well being, always supporting and protecting him. Her attainment of the Demon Spear Gae Bolg was largely due to her desire to protect him. Since his ascension to Magic King, she has grown more concerned about his state of mind, wishing that he'd stop fighting to slow his awakening to Astral Trinity. Arin has also shown jealousy when he interacts with other girls; although, she does not mind him being with the Trinity Seven.

Appearance
Arin is a petite, slender young woman with short light blue-gray hair and a single ahoge. Notably, she also bears a striking resemblance to Hijiri Kasuga. However, Arin normally has an emotionless expression, rarely changing her expressions. Although, since meeting with Arata, she has begun to show a wider range of emotions. Her usual outfit consists of her school uniform, a white collared dress shirt worn with a dark blazer jacket with the school emblem, and a plaid mini-skirt. She also sports a plaid cravat bowtie, black knee-length socks and loafers. On her left ring finger, she wears a simple band ring wtih rune inscriptions that are seen when activating her magic.

Magus Mode: In her magus mode, Arin switches to a dark one piece mini dress under a long sleeved hooded robe with white lace trims and tied with a thin red ribbon in a cravat knot. Her socks and shoes remains the same.

History
Unable to remember her name and origin, much of Arin's past remains a mystery to even her. Her earliest memory is when she was around eight years old, she was shrouded in darkness before growing conscious of her existence. She would suddenly find herself in an unkown location and becoming first aware of the world around her, which the experience would cause her to cry. Later, while wandering around, she would meet the Biblia headmaster who told her her that he had come to pick her up. Bringing her to the Royal Biblia Academy, the two would encounter unknown monsters that no one else had previously seen before. Although some of those monsters were easily defeated, there were also several that they were forced to flee as suggested by the headmaster despite his Paladin class.

Eventually, she would arrive and enroll at Biblia, as well as becoming a member of Trinity Seven. Notably, during times she left the Academy grounds, the previous unknown monsters would appear again outside the academy.

Chaotic Rune


Arin's Thema is Ruina from the Ira Archive, and her branch of magic is Chaotic Rune, which is based around the ancient writing style Norse runes. Specifically, Chaotic Rune manifests the power of gods into runes, capable of overpowering Magic King magic once enhanced. Using macros recorded in her grimoire Laguna Yggdrasil, she is able perform a wide variety of spells both offensively and defensively by drawing symbols with her finger. Additionally, her magic is also considered to be one of the more destructive ones out of the Trinity Seven. In one instance, she was able to forcefully remove the Astil Manuscript's restriction on Arata, causing his power to become unstable.

Upon receiving the Demon Spear Gae Bolg due to her desire to protect Arata, Arin's magic abilities increased even further, even once breaking down time and space to teleport herself. Her offensive abilities, in particular, also futher improved, able to outclass melee-types now despite once being only spell oriented.

Chaotic Rune has also been shown to be very compatible with Yui's Arc Symphony. By combining her spells with Yui, her magic is greatly enchanced, to the point of stopping a Magic King Candidates attacks. Furthermore, upon transforming Gae Bolg to God's King Spear Gungir, she can achieve another third of the Trinity. With Yui's Arc Symphony supporting her magic, she gains the Thema Victoria allowing her to complete the Trinity. At this stage, she has a very staggering amount of magic that becomes difficult for her to control.

Arin was able to access the Library by pouring her Ruina magic into Laguna and gain possession of Gae Bulg.

Weapon

 * Arin_Magus_Mode_Gae_Bolg_ch42_MN.jpg Spear Gae Bolg - Due to her desire to protect Arata, Arin traveled to the World Tree Library where she recieved the Demon Spear Gae Bolg, which originally belong to Scathach, the founder of Chaotic Rune magic. This spear has the ability to nullify magic from the Ira archive and even allow her to break time and space on one ocassion. Also, Gae Bolg is said to be so powerful it can pierce any defense. Additionally, the spear is also a cornerstone for her Partum Thema.

Royal Biblia Academy
Arata Kasuga - As the partner of the Magic King, Arin cares very deeply for Arata and as well loves him, becoming quite attached to him since his arrival. She often calls him her husband, and considers them to be already married. Arin first met Arata in the men's bath unclothed, although she was rather nonchalant during the whole experience. However, because of the nature of their relationship, Arin developed a strong interest in him mainly for her research. While on the other hand, Arata was unsure how to interact with her due to her blunt personality and identical appearance to Hijiri. Regardless, the two of them quickly became good friends, even after Arin trapped him or even caused him to create a Breakdown Phenomenon. Arin does not mind Arata's shameless personality, even willing to comply with some of his desires. Likewise, he has also become used to her, appreciating her support and guidance. Although, they sometimes still find aspects of each other surprising and troublesome as well. Notably, since meeting Arata, Arin has slowly begun to change from her usual emotionless behavior, showing more different emotions which has been noticed by her friends. The both of them genuinely care for one another, willing to support and protect each other during dangerous situations. Arin's attainment of the Demon Spear Gae Bolg was largely due to her determination to protect him. Also, Arin can become jealous whenever he interacts with other girls, but is more or less fine with her friends in the Trinity Seven.

Trinity Seven
Lilith Asami - As members of Trinity Seven, Arin and Lilith are good friends and usually get along very well. Although, due to Arin's straightforward character and lack of common sense, Lilith often times has to correct her actions and behavior, which Arin usually finds difficult. Despite this, the two of them care for one another, willing to fight and protect for each other. Furthermore, while Arin is sometimes jealous of Lilith's closeness with Arata, she actually does not mind and both of them continue to remain on friendly terms.

Yui Kurata - Yui and Arin are good friends, both willing to fight and protect one another. When Yui's magic becomes unstable and causes a Breakdown Phenomenon, Arin is one of the people who helps save her. Also, despite the two being interested in Arata, they still remain on friendly term. Although they sometimes get jealous of each other's interactions with him. At one point, Yui has stated that she was willing to be his mistress because Arin was his partner. During battles, both of them have been shown have excellent teamwork as their magic complements each other. For the Magic Research Showdown, they were paired together as a team and faced off against Arata and Lieselotte. With their combined efforts, they would control the majority of the match and greatly overwhelm their opponents. Finally, Arin, with the support of Yui, would achieve the Trinity, defeating Arata and Lieselotte.

Iscariot
Hijiri Kasuga - Arin and Hijiri are believed to have an unknown connection due to their very similar appearances and magic. Both of their Thema's are Ruina from the Ira Archive and they also utilize the same Chaotic Runes magic. However, their personalities are quite different as Hijiri displays more emotions than Arin. Furthermore, as members of Iscariot and the Trinity Seven respectively, Hijiri and Arin are enemies. When Hijiri was about to destroy Arata and Lilith, Arin gained the Demon Spear Gae Bolg to break down time and space to save them. Despite the two meeting for the first time, neither of them would comment on their unusual similarities. Notably, Arin's possession of Gae Bolg allows her to nullfiy magic from the Ira Archive, making her a natural opponent to Hijiri.
