Kihara Byouri

Kihara Byouri (木原病理) is a character introduced in Shinyaku Toaru Majutsu no Index as part of the infamous Kihara clan.

Beyond her seemingly wheelchair-ridden humble woman, belies a nature fitting of that of a Kihara. She is one of the members of her family ordered by Academy City to attack Baggage City and destroy the Natural Selector tournament held by the Anti-Academy City Science Guardians.

Etymology
As a member of the Kihara family, which has names that are often related to science and mathematics, Byouri's name can be translated as Pathology.

Appearance
Other than the obvious wheelchair, Byouri appears like that of a woman with tea colored wavy hair, tied up in a pony tail. She wears a pyjama, as if she was a patient of a hospital. One of the most recognizable characteristic she has is her blank brown eyes, which is often seen nearly covering the entire cornea.

Personality
Byouri hides her true nature with a facade befitting with that of a kind and helpess woman. Her true nature befits that of a true Kihara, having no problem with killing people off, as with the case in her attack in Baggage City. To complement this, she is also terribly devious, using her weak-looking nature to her own advantage.

In her own words, she refers to herself as a someone who is good at giving up. She indicates that she has given up on many things, and on forcing others on giving up. She is described as being one of those who give up on things.

However, since implanting Equ.DarkMatter into her, Kakike Teitoku's presence is still there, and is trying to reject Byouri's consciousness, as if Teitoku is taking control of Byouri's mind. Kagun believes that this maybe the reason why she does not normally use her power.

Background
As part of her nature, she has apparently forced several people to "give up" on their dreams and ambitions. It is unknown on how many other things Byouri has given up on.

Three years prior during spring, sick of Kihara Kagun being a teacher looked up to by students, as it was unbecoming of a Kihara, Byouri prepared a student that was erased from the records, corrupting him and making him give-up, as is her especially, for her to force Kagun into giving up being a teacher. It works, as Kagun kills Byouri's pawn and resigns as a teacher, though she may have not anticipated in Kagun leaving Academy City.

As part of the aftermath of the invasion of Hawaii, she, Ransuu, Enshuu, and several units of armed Academy City personnel, infiltrate Bagge City on November the 13th, and launches a terrorist attack on the city.

Shinyaku Toaru Majutsu no Index

 * Main article:Baggage City Arc

She first appears right after Marian Slingeneyer brutally massacres several Academy City operatives. Here, she introduces herself as a weak wheelchair-bound woman, although, Marian discovers this shortly thereafter, and attacks her. Marian is later surprised by Byouri's ability to maneuver herself in a wheelchair. Byouri engages Marian with her mechanically enhanced wheelchair, which forces Marian to transfigure the bodies of the Academy City personnel she killed earlier into her form to dodge Byouri's assault.

As the battle continues, Byouri reveals that her wheelchair can have legs, making herself more maneuverable. However, Marian later dominates her by bending the legs of her wheelchair, and later cornering her in the burnable garbage area, near a pit for garbage to incinerated later.

With her wheelchair stuck, Byouri is forced to use the machine on her legs that allow her to stand up. Byouri takes a machete-like blade from the back of her wheelchair and tries to attack Marian. However, due to her quick thinking of calling Academy City reinforcements for Byouri, allowed her to use their living bodies for transfiguration, and from there catapults Byouri into the pit, leaving her for dead.

She manages to survive however, and meets up with Kihara Enshuu, who helps her out of the trash compactor pit. With no choice left, Byouri is forced to user her trump card and activates his Equ.DarkMatter implants, taken from Kakine Teitoku. Here, she grows wings from her knees and thighs allowing her to walk. After lecturing Enshuu on the nature if the Kihara, she turns her back on Enshuu, Byouri takes this opportunity to attack her, reasoning that it may bring out a better Kihara if she is loss. Surprisingly, Enshuu notices this and uses the thought pattern of Kamijou Touma to attack her, Enshuu later leaves her with bloodied hands.

Still though, Byouri survives Enshuu's attack on her and is able to discover that she has been defeated by Kumokawa Maria, Saflee Opendays, and Oumi Shuri. Here, she tries to attack them after transforming again from afar but is unable to, as a helmeted man appeared, forcing her to attack him, though, his helmet is destroyed, she finally discovers the true identity of the masked man, Kihara Kagun. Here, he reveals that he has manipulated events, in order for Byouri to lose all of her safety devices, as proof that he had killed her, as so he can fight her on the same level. Kagun blames Byouri for corrupting the attacker of his students that forced him to kill him in front of them. The attacker was a pawn prepared by Byouri many years ago, in order to force Kagun in giving up becoming a teacher that is looked up to, someone who is so unlike a Kihara, and now redemption for him is to kill her.

With her projectiles, Byouri attacks Kagun, but he was somehow unscathed by the accurate attacks. Kagun then reveals his power, a laser blade that he held between two fingers. Here, he severs Byouri's transformed arm, which Byouri manages to transform again, to that of a large furry arm. She tries to crush him with the arm as he was standing on an elevated level, but is once again unscathed, and uses his power to pull Byouri down to his level. Byouri continues to attack with both her Skyfish and Yeti forms, but to no avail, as Kagun simply cuts the Yeti arm apart. While being preoccupied on how Kagun gaine his powers, he attacked her head, destroying the brain. However, because of this, it activated another form of her powers, Little Gray, and Byour's limbs began to expand as if inflamed. An explosion occurs and engulfs Kagun, and Byouri is completely deformed due to the use of her powers. However, Kagun survives, though his clothes were rip apart, telling her that he will never be damaged. Byouri realizes that Kagun maybe a part of GREMLIN, and may be using laws that are outside the realm of science, an alien landscape for a Kihara. Realizing that Byouri cannot kill him immediately, she resorted on giving him light injuries to bleed him out, which Kagun realizes. Kagun reveals his power, the Whitting, a sword that scatters when its owner is at a disadvantage, creating a miracle, allowing the wielder to avoid damage accurately, and cause the sword to be sharper, and when it is reassembled, the sword's destructive power increases exponentially. Kagun questions why Byouri did not use her power until the end, and conjectures that she may be losing herself due to the 2nd Level 5.

Suddenly, Byouri transform again into Loch Ness, forming into a giant monster. Seeing this, Kagun reveals that he is not planning to win, and would rather have a stalemate were the both of them die. An explosion occurs, and the both of them fall into Maria's path, and here, a severely injured Kagun stabbed Byour's monster head, and wrenched it off clean from its body.

Equ.DarkMatter
As a last resort, Byouri has her Equ.DarkMatter transplanted into her. However, she requires authorization to use it, as there is a threat of losing control. In the arc, she has Enshuu hold it for her. The most common attribute of this power is her ability to recover quickly from injures as well as allowing her to use transformations, these transformations can be used at the same time. All these transformations are named after cyptids, or creatures whose existence has not been proven

Transformations

 * Base Form - This allows her to heal from any injuries as well as allowing her to walk, an aftereffect of this is Byouri growing wings from her knees and legs.
 * Reference: Skyfish - Based on the cryptid known as the Skyfish, barbs or darts form on Byouri's arm, allowing her to use them as a projectile. It is compared to that of a metal nail, can pierce through metal containers, and can be fired accurately from 1000 meters away.
 * Reference: Yeti - Based on the Yeti, Byouri's arm changes into a large and furry form. It has tremendous strength, allowing to crush metal containers with ease.
 * Reference: Little Grey - Based on the Grey alien found in popular culture, a tremendous change occurs to Byouri, where her limbs expand as if inflamed, and can be descrobed to being as large as a toddler's scalp. This change was once considered for use by Academy City residents, as it primarily served as a function to build the brain, though ti was a failure. Here, Byouri's right and left arm respectively to that of a giant's arm and a five-brained monster. Byouri can use the power of this form at Level 2 or Level 3, and with it can cause an explosion and can peel off flesh and blood from the bone.
 * Reference: Loch Ness - Based on the Scottish legend of the Loch Ness monster, is the last known and most extensive transformation Byouri has. Simply put, Byouri changes her entire body into that of large dinosaur-like creature. Byouri is still able to communicate in this form.

Other abilities
She has no powers, but is still very dangerous. Her wheelchair is Made in Kihara, presumably since it was developed by the Kiharas. Her wheelchair contains a machinegun and cannon with a caliber great enough to fit a human arm, as well as a machete-like weapon. Furthermore, Byouri can transform her wheelchair into a walking mechanical carriage, like a spider, allowing for more maneuverability than that of her wheels.

Finally, if there is a need, there is technology installed on her legs, like ribbons that wrapped around her it, which obviously allows her to make use of her legs.

Quotes

 * (To Marian from NT4) "...Those who are hated must put in more effort and skill than those who are popular to survive this far. Humans grow the most when they stand up to difficulties."
 * (To Kagun from NT4) "This is a Kihara. We use science as a base humans exist on, use these methods and create breakthroughs through areas that far exceed expectations. Can you understand the essence of it?"
