Oriana Thomson

Oriana Thomson (オリアナ＝トムソン) is an 18-year-old blonde magician who was born in England yet affiliates to no one and works as a mercenary. Her sorcery name is Basis104, "The one who carry the basis." (礎を担いし者)

Background
She's known as the Route Disturb (追跡封じ (ルートディスターブ) ), a top-notch courier in the magical world. This woman’s ability is that she’s able to run and hide, and that she’s able to get away from pursuers even if they find her. More accurately, Oriana is a woman who will do anything to get away from her pursuers. Also, nobody is able to keep track of her actions. Even when they are prepared, she'll still be able to get away. Oriana Thomson is a magician with many spells at her disposal, and she'll destroy bridges, create fires, set up many talismans to get her pursuers off her back.

It has been explained that Oriana is extremely talented in tracking people as well, almost as good as she is in loosing track of them. This is due her own prowess in escaping from pursuers; in order to achieve that feat she needs to know the current mind set of who is searching for her as well as being knowledgeable in any magic that might be used to trace a target; in other words in order to accurately lose track of an enemy, she indirectly learnt the necessary skills for pursuing at it's finest.

Personality
Oriana is not above using her attractive looks to make others vulnerable and is an escape master able to use a "human wall" formed by a crowd to slip inside. She is shown to have no intention of involving civilians purposely; when she was chased by Necessarius and normal citizens with no link to magic claimed to be her "best friend". She shows regret for hurting Aisa Himegami and stated that she would finish her mission especially if it guaranteed the happiness of others. She is shown to be flirtatious when she teasingly asks Touma if he wanted a kiss and is considered a mature, older sister.

Daihasei Festival Arc

 * Main article: Daihasei Festival Arc

She first appears during the Daihasei Festival, for which she was hired by Ridovia Lorenzetti for the transportation of a magic artifact ("The Cross of St. Peter") to Academy City. During this, she meets Touma who dispels her Chaos and calm on the surface spell after she shakes hands with him thus forcing her to retreat as she is pursued by Touma and then by Stiyl and Motoharu; during the chasing she attacked Himegami out of fear and her trap hurt Fukiyose inadvertently, severely injuring both of them to the point of near death. She's also laid traps to hurt Stiyl and defeated Tsuchimikado in battle.

Eventually she fought Stiyl and Touma in District 23 at the best location to set up the Croce di Pietro in Academy City, and was defeated after a prolonged battle.

Document of Constantine Arc
When Ridovia was exchanging information with Stiyl it was mentioned Oriana had accepted a deal to work for the Anglican Church against the Roman Catholic Church, in order to get out of being locked up.

English Civil War
She is hired by Necessarius to help them investigate the source of the Euro Tunnel explosion. She along with Touma investigates about New Light, and both together end up chasing the magician girl Lessar and consequently defeating her. When Lessar told them their job as convoys and was about to reveal the identity of her employer, Lessar is shot from a long distance weapon which she recognizes as a job from the English Knighthood. At the end of the 18th novel, she helps Sherry who lost her control fighting English Knights, and after that was hired by Villian to track down William Orville before they face off against Carrisa.

Abilities
After seeing Oriana in action Stiyl and Tsuchimikado comment on how Oriana's magic isn't "similar to that of mages", as magic normally requires proper preparations and certain conditions to be utilized; instead Oriana's magic resembles the skills of a magic author, a person who is able write magical words and create results that can't be reached by normal spells from magicians.
 * Chaos and calm on the surface: Is a spell that has the same function to Stiyl's Opila runes but this applies only to Oriana herself. This allows her to move around without being detected by people or technology.
 * Snapshot20101127130036.jpghand (速記原典 (ショートハンド) ): Oriana is gifted in the fact that she can "write" shorthand originals, Grimoires that contain spells. However, she can't maintain them due to her writing being too sloppy, so they vanish after a set time or after one use and she can't use the same spell twice if she has one flash card. Her spells revolve around the Four Elements, with one of four words - " watersymbol ", " windsymbol ", " soilsymbol " and " firesymbol " - usually written on the slip of paper to invoke a certain elemental spell. In fact, she deliberately uses the wrong combination of colors to cause the spell to become unstable. The reason for this ability is called Shorthand Original is that writing a magic page that has a magical power similar to that of a magic circle takes months or perhaps years to complete, the shorthand allows her to achieve that result by doing a "quick" version of the page in very little time, although the process is extremely quick she is forced to stick to some restrictions as a side effect. This method of crafting spells are also governed by laws of Western Astrology.
 * Route Disturb (追跡封じ</rb> (</rp>ルートディスターブ</rt>) </rp>): Her specialty is that she’s able to run, hide, and evade from pursuers even if they find her. More accurately, She'll do anything to get away from her pursuers, even if it causes collateral damage.
 * Counterspell - Oriana uses disruptive spells to counter spells which trace her location, like the All-Around Reality Array. She does this by reverse-engineering the mana targeted to her, which in theory contains the life force signature of the caster. She then uses this information to target the caster from any distance.
 * Hand-to-hand combat - Oriana has experience when it comes to melee combat, utilizing seductive and suggestive "stances", which coupled with her already distractingly attractive appearance results in a strike-grapple-and-counter style that robs her male opponents of any and all concentration.
 * Reverse Engineering - This is an skill that Oriana has shown whenever she manages to detect someone using a tracking spell on her. By identifying the characteristics of the effects that she is experiencing, she can quickly get an idea of what spell was used to track her or how it that spell was performed. If she has taken the proper counter measures prior to being target of a spell she has been shown capable of dispelling it as soon as it was cast or she can even turn the effects of the magic against the caster.

Design evolution
The overall design of Oriana Thomson remains the same throughout the series. Early drafts of her character had her wear clothes much more moderately, in comparison to her finish design, and had a smaller bust. This is completely redone in her last design for the 9th and 10th light novel volume, with her wearing much more daring garments and her breast size increasing to the point of physical impossibility (a point that Haimura noted and quickly disregarded). She was apparently designed to look like a wife instead of an Onee-san, making her look much older despite her age.
