Railgun SS3

**Sakibasu Yuri** (咲蓮誘璃, *Sakibasu Yuri*?) is a first-year student of Tokiwadai Middle School and a member of Shokuhou Misaki's Clique, introduced in *Toaru Kagaku no Railgun SS3*.

## Appearance

She has black hair in twintails and curls. She wears the standard Tokiwadai uniform.

## Personality

She is quite prideful and boastful, showing off her Stativarius violin to Kuroko as well as her talent in using it. However, beneath this facade is an insecurity, as her family is low-born and their wealth comes from her inventing a card game. She uses the prestige of the Stativarius violin to elevate her family's social standing.

## Background

Yuri was born to normal parents, and they struggled very hard in their jobs to give her a better life. When she was five years old, she created a trading card game, "Witch & Psychic", that became a world-wide sensation, being played in over 49 countries and predicted to be even more ubiquitous than regular playing cards. This made her and her family massively wealthy. Although her family had become wealthy and was proud of her accomplishments, the upper-class still rejected them as they came from a lower social standing, and she felt guilt that she may have broke something irreplaceable in her parents by elevating them from their lot in life.

She later enrolled into Tokiwadai Middle School, and seeing that her ability might be useful, Shokuhou Misaki had her join her clique. Misaki later got her in touch with the Chandelier Auction House. Here, by using her ability, she managed to win a genuine Stativarius violin, much to Misaki's dismay as Yuri had become worked up about it.

## Chronology

### Toaru Kagaku no Railgun SS3

*Main article: Toaru Kagaku no Railgun SS3*
On a quiet afternoon at Tokiwadai Middle School, she caused trouble for Shirai Kuroko and challenged her to a violin competition in their music elective. Despite her performance of Air on the G String with her legendary violing, she lost to Kuroko who used a handmade violin, a custom sound reflector, and an original song to take advantage of the 3 minute limit given to them. She later joined Kuroko, Misaka Mikoto, Uiharu Kazari, and Saten Ruiko in a family restaurant after being invited by them. She conceded defeat and was later told by them that she had value, her talent, beyond what the legendary violin gave her. To that end, she was asked to demonstrate her musical skills with a normal violin.

Following Yuri's demonstration of her skills, the restaurant was attacked by a man on a motorbike who fired at the girl's table with a shotgun. When Anti-Skill officers came to investigate the attack, they insisted on taking Yuri in for questioning in regards to the Stativarius violin. This prompted Kuroko to declare that Judgment will retain investigative rights instead of handing them over to Anti-Skill as planned.

As the group went back to the Tokiwadai dorms, the girls discussed the attack, figuring it had to do with Kuroko triumphing over Yuri at the violin competition. They concluded that before the competition, the Stativarius was considered a status symbol that granted its owners access to special services. However, after the competition, the Stativarius's reputation as "a violin with the world’s greatest music" is in jeopardy, causing their owners to potentially lose out on whatever access they obtained via the violin's reputation.

As part of the investigation, Yuri used her existing contacts with the Chandelier Auction House to arrange a meeting with one of their representatives at School District 6. The representative explained that they aren't the ones who are auctioning off items to be used as "keys", but the buyers are using them for that purposes off site, and are bidding at greater prices than normal. Yuri pleaded with the rep to provide a list of clients, but he couldn't, citing that the auction promised confidentiality. However, he hinted that those clients would have required the services of other companies for their purchases, like insurance.

The following night, Yuri spotted Mikoto and Kuroko sneaking out of the dorms to investigate National General Life, the only insurance company in Academy City that provided policies for stringed instruments like the Stativarius violin. Yuri managed to follow them, only to find Mikoto pinned down by an assailant. Yuri took a nearby concrete block and bashed it on the assailant's helmet. To the girls' surprise, the helmet flew off, revealing no head, meaning Mikoto's attackers were actually clothing manipulated with high-level telekinesis to mimic human movement. After Mikoto dealt with those attacking her, Yuri grabbed a piece of black leather that was once the attacker's riding suit, saying her Carbon Search ability will be useful in the investigation.

## Abilities

She has an esper ability known as **Carbon Search** (有機探査（カーボンサーチ）, *Yūki Tansa (Kābon Sāchi)*?, lit. "Organic Probe"), which allows her to read and precisely measure the carbon isotopes of objects. This has a number of uses, from detecting if food is spoiled to accurately appraising products like leather, antiques and artwork, searching for geological layers and mineral veins, detecting insects like mites/fleas, and even performing accurate biological scans of the human body including blood vessels, nerves, tendons, marrow, lymph nodes, and muscle fibers. By spreading something like cornstarch in the air, she can accurately read the movements of the corn starch powder distributed thinly through the air, and thus read the flow of the air itself, allowing her to essentially perform a three-dimensional scan of the space around her. She has used this to locate a enemy hidden behind cover and accurately predict and repeatedly aim dodge the shots of their shotgun by reading the motion of their gun in the air. She also subtly altered the density of the cornstarch in the air using a handkerchief to gather it around said enemy, where it caused a dust explosion from their clothes' static electricity. She can also use her power to track the invisible footprints left from the cornstarch in their shoes if they step on it. She can also replicate these feats with flour, potato starch, pancake mix and powdered medicine made of sugar or carbohydrates. As a student of Tokiwadai Middle School, she can be assumed to be at Level 3 or 4.

### Magic

During her battle with Ryouu, Yuri wielded the Stativarius Ainsel, which enabled her to use magic. Yuri can use Ainsel's support to produce powerful sound-blasts and even use the sound to cast various magic spells that summon and manipulate the four elements of fire, earth, air and water (which includes ice). Specifically, she has shown spells that create a mini-tornado that can swallow up flames, ice pillars that can act as a physical barrier and magic circles that can deploy giant sharp ice shards/spikes. The magic circles for the spikes are created in the floor as if they were landmines, with Yuri being able to fill an entire room with them while leaving an open gap for herself and her allies. As an esper, using magic causes immense physical backlash in her body due to the incompatibility of the two systems. However, Yuri managed to use Carbon Search to scan her own body, locating the issues and smoothing all of them over, mitigating all side effects of using magic.

Unlike the Stativarius Tam Lin, Ainsel does not openly communicate nor it controls Yuri's body like Tam Lin does with Yuri's mother, the two act more like partners than master/servant like Tam Lin and Ryouu did. It's likely Ainsel can prevent mind-controlling powers that only affect humans like Shokuhou Misaki's from affecting Ryouu by putting its non-human mind in the way like Tam Lin did. Upon destroying Tam Lin, Mikoto Misaka saw Yuri grow pure white wings and a glowing halo, but these only lasted momentarily before dispersing into glowing particles and disappearing.

### Other abilities

Like her mother, Yuri is quite skilled at violin playing to the point where not even Misaka Mikoto, a violinist herself, and Shirai Kuroko could match up to her talent no matter how much they tried.
