Arin Kannazuki

Arin Kannazuki is the Trinity Seven of the Ira archive and 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 blank expression and rarely showing any other emotions. Because of this, many of her actions and expressions usually do not match. Furthermore, Arin has also often been shown to lack a common sense and generally does not react 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 quietness. 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.

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 Gungir 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 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 red 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 cape with white lace trims and tied with a thin red ribbon in a cravat knot. Her socks and shoes remains the same.
