Frenda Seivelun

Frenda Seivelun (フレンダ＝セイヴェルン) is a character introduced in Toaru Majutsu no Index. Originally a minor character used to expand the growing mental breakdown of Mugino Shizuri and the destruction of the first incarnation of ITEM due to her betrayal, Frenda's character is later expanded in her appearance in Toaru Kagaku no Railgun.

An operative of the Academy City-based underground team called ITEM, she is one of the main combatants of the team, having incredible prowess in close-quarters combat, as well as expertise in traps and concealed weaponry. Her full name is revealed to be Frenda Seivelun, upon the introduction of her little sister by the name of Fremea Seivelun.

Appearance
She is a girl with blonde hair and blue eyes. She is most often depicted with a black sailor top and a pleated skirt. She also wears a pair of pumps and dark-colored pantyhose. A dark-colored beret adorns her head.

Personality
She and ITEM's leader Mugino Shizuri have a sort of a master-servant relationship, with Frenda usually being scolded for her fits of unprofessionalism at work. Out of combat, she seems to enjoy talking about ordinary things girls her age would talk about; she also values her legs highly, saying that it is her pride as a woman. In battle, though, her moves can be difficult to read as her humorous remarks often serve as a diversion; this in turn, combined with her cunning style of combat, can prove to be a deadly combination. She is also somewhat vicious and possesses a blood-thirsty nature, indicating that she enjoys taking away the life of someone as if she was destined to end them.

She has the habit of often using the term "Kekkyoku," which can be translated as "Basically" or "In the end" in her speech. Her younger sister also has a similar trait.

Battle Royale Arc
Prior to the start of the events of October 9, she participated in the killing of SCHOOL's sniper, though they were unconcerned on why they targeted Oyafune Monaka in the first place.

She first debuts along with all the other members of ITEM immediately after the assassination attempt on Monaka's life by SCHOOL in a family restaurant. Apparently having trouble with a can, she uses the tools taht are used in blowing up a door's lock to open it. She complains about the contents of the can, being canned mackerel, as she is getting tired of the taste, she then states that she wants curry. After Hamazura Shiage mulled on the uneven male to female ratio as well as Shizuri finishing her lunch. Shizuri begins saying on how before noon, someone attempted to assassinate Monaka. Shizuri states that the higher-ups want to them to take action regarding that. Frenda comments on she doesn't have information on that. Hearing this, Shizuri orders Shiage to send the details of the incident to everyone's cellphone. With a halfhearted response Shiage does so, though he accidentally sends a pornographic video (likely related to bunny girls) he downloaded from the Internet. When the ITEM members see this, all of four snapped their cellphones shut and looked at him with scorn. Shiage tries to amend his mistake by trying to send the information again, but he however is chastized by them. Shizuri is lost in words, only being able to say his name. Frenda says that he is disgusting. Kinuhata Saiai asks if Shiage likes bunny girls. Finally, Rikou says that she is rooting for him. Trembling at their words, he makes sure at sending the information to all for them.

Their conversation begins with Saiai pointing out on how she was sure that they took out SCHOOL's sniper three days before. Shizuri says that SCHOOL likely hired a new one and ignored their "warning". Frenda states that back then they didn't debate why they were targeting Monaka, but realizes that there must be something up if they still wanted to assassinate her despite her low value even amongs the Board of Directors. Rikou adds to Frenda's conclusion, repeaing what Shizuri says. As Shizuri tries to think on the reason why SCHOOL went out of their way to try in killing Monaka again despite her low value, she asks for Shiage's opinion. Shiage tries to give an answer but his response didn't actually have anything in it. Disappointing everyone, with both Frenda and Saiai calling her disgusting, while Rikou says she'll root for him even everyone else is calling him disgusting. With this disappointment, Shiage kneels on the ground and is promptly ignored. Shizuri goes back on topic and proposes that SCHOOL targeted Monaka because there's no value in killng her. Saiai is confused, to which Shizuri says that SCHOOL probably didn't care who it was as long as it caused a disturbance, choosing a VIP whose death whose death wouldn't have much of an effect and didn't have strong security. Frenda then states that she feels sorry for Monaka. Feeling proud, Shizuri gives her hypothesis on what SCHOOL is after, starting on how if a VIP of Academy City are in danger, people are called in from all sorts of places. She says that roads are blocked off in order for ambulances to travel on as well as important people from various medical industries gather at the hospital for them. Saying this, Shizuri asks on what would happen if someone attempted to assassinate a VIP, and she answers on how people will be called in to protect the facility where the VIP will undergo treatement. Shizuri concludes that SCHOOL will do something amidst the confusion. Saiai states that their methods are boring. Shizuri then speculates on what the facility they would be targeting after the creating the commotion. Frenda concludes that Monaka was just SCHOOL's insurance for their plan to be in order and that they are still planning on attacking their real target, to which Shizuri agrees. Shiage then speaks up again, asking if what SCHOOL did was really an attempted assassination. Shizuri says it probably didn't matter as Monaka may be revived by Academy City's mysterious technology even if she died. Shizuri then orders that they need to find the facilities that have insufficient security due to the assassination attempt. She then adds taht they also need to see what has changed had the assassination been successful, stating that SCHOOL may have made a situation where they could move whether the sniper succeeded or not, indicating that there might be a facility that has its security reduced regardless as it may be where SCHOOL is headed. She then orders Shiage to find a car for them as they may be heading out soon. Shiage becomes irrirated on how Shizuri said her orders, but he is forced to acquiesced. However, Shiage complains on how he was once he leader of over 100 Skill-Out, to which Shizuri says that it is true though she doesn't his point. Shiage then leaves to find a car with a heavy heart.

After Shizuri's argument with the ITEM liaison regarding their next job, to which she later approves after seeing that they are after SCHOOL, the girls get on the car Shiage had just stolen for them, impressing Shizuri. Shiage asks where they are going, to which Shizuri states that they'll be going to Kirigaoka Girls' Academy in School District 18 as there is a particle engineering laboratory nearby that she believes is SCHOOL's target as the place has become disrupted after the assassination attempt on Oyafune Monaka. Shizuri mentions that there are multiple places that she suspected but states that the particle engineering laboratory. Hearing this, Shiage asks what they are after there, though Shizuri says that she doesn't know, but says that it is better than dealing with the whole Oyafune Monaka thing. Shiage then starts the car. Rikou then asks if Shiage has a license, to which he responds by saying that he doesn't need a card to drive, only skills. He then drives ITEM with the automatic transmission car.

Shizuri chose wisely as they later find SCHOOL and its leader Kakine Teitoku there, resulting in a battle. Despite the Boy with goggles being killed in the skirmish SCHOOL still retrieves the Tweezers from the facility, their goal for infiltrating the facility in the first place, and later decides to flee instead of continuing the battle. In the haste of trying to chase after SCHOOL, Kinuhata Saiai and Frenda are left behind in the facility.

What occurs next is a mystery, but apparently SCHOOL comes upon Frenda by herself. Here, she is questioned regarding ITEM's whereabouts and on how they were able to track them down. According to Shizuri, Frenda was afraid of SCHOOL, and as such betrayed that knowledge of ITEM hiding out in a room in the Private Salon as well as Takitsubo Rikou having AIM Stalker with the promise that SCHOOL will let her go unharmed. It is likely that Teitoku was present in the interrogation. Later, Frenda goes into hiding, though a place not secret enough for Shizuri to find.

After Shizuri escaped Teitoku during SCHOOL's attack on ITEM in the Private Salon, Shizuri either somehow discovered that Frenda betrayed them or came to the conclusion that only Frenda could've betrayed their location herself. She goes on a solitary manhunt for Frenda, already deep in her desire for vengeance against SCHOOL. Shizuri later finds and executes Frenda, cutting her in half at the waist with her Meltdowner ability.

Shizuri later carries the upper half of Frenda's corpse after "purging" her from ITEM. She later lets go of her corpse as she confronts Shiage. It is unknown what the fate of Frenda's corpse was, though it is likely that it was later disposed of by ITEM's subordinate organization.

World War III
Frenda's death at the hands of Shizuri permanently scarred the Rank 4 Level 5, although the effects were not evident until her encounter with Hamazura Shiage in Russia. In spite of her unstable mental condition, Shizuri admits that she regrets having murdered Frenda and wishes to reunite the members of ITEM after what happened in the past.

Freshmen Arc
Mugino Shizuri later visits Frenda's grave in School District 10, while the other members of ITEM wait for her. Due to the narration regarding the fate of the bodies of those who have died and are in the Dark Side of Academy City, it is likely Frenda's grave does not even contain her ashes.

Homecoming Arc
Shizuri arrives at the Kamijou Residence trying to look for Shiage since the last arc and later finds Fremea Seivelun there with him. She believes her to be Frenda's ghost at first. Shiage tries to introduce her to Shizuri, but then realizes that he has forgotten that Shizuri was the one who killed her sister. Unable to find the words to say to Fremea, Shizuri does it for him, she bluntly says to Fremea that she is the girl who killed her. In anger, Shiage chastises Shizuri, and tries to move her away, though is completely outclassed by her. With a bit of a distance from Fremea, Shiage berates Shizuri for her lack of subtlety, to which Shizuri simply says that she came clean. Shiage says that is something not to be proud of. His lecture however is interrupted by Fremea looking towards them, and tells her that he will say something to fool her, saying that Shizuri shouldn't do anything to make the situation even more complicated.

Ichihanaran Festival Arc
After Kakine Teitoku is released by Kihara Yuiitsu to go mad in the City, a being that sounds and looks like Frenda appears before Shizuri after she goes out to get some water bottles. Here, the Frenda-being tells Shizuri that she is different from the last time she saw her, and that despite her coming to terms with her death, it doesn't mean that her anger should disappear.

Despite the person's inane mind games and guilt-tripping, Shizuri defends herself and easily defeats her attacker, reasoning that her electronic eye was tampered with to make her see her attacker as Frenda. Saiai arrives and confirms that the attacker was a middle-aged man wearing Frenda's clothes. Shizuri then mutilates the man utterly into a broken ruin, but keeps him alive as an example to what she had said. She and Saiai later dragged his ruined body before a strange research facility, and tell each other to keep the incident a secret from Shiage.

Shizuri later appears before Kakine Teitoku himself, and suspects him for the reason behind the Frenda impersonator, as he was the biggest factor from the dark side of Academy City active at that time and the interest in playing with the dead was the same. She tells him that she doesn't know what his purpose was with what he did, and tells him that she will make him pay for disturbing her grave.

Level Upper Arc
She and her teammates are first seen during the climax of the Level Upper Arc. They are in Joseph's Coffee and Restaurant arguing whether or not they should go into a public or private pool since it's summer. They later hear the Level Upper treatment program on the P.A. System, unaware of what's exactly going on and waking up Takitsubo Rikou. In the anime adaptation, their conversation is complete cut-out, only leaving them being reacting to the the noise being played all over Academy City.

Sisters Arc
Frenda and ITEM reappear during a string of attacks by Misaka Mikoto on research facilities related to the Level 6 Shift, when Shizuri receives a call that they are to protect a medical facility. Frenda is sent to guard a facility that is one of Mikoto's targets while Shizuri and the others are in another facility. The facility that Frenda is in gets attacked by Mikoto.

Frenda uses her white tape to destroy various objects in the facility as well as the dolls with bombs inside them to attack Mikoto, though Mikoto is first caught off-guard, her superior mastery and power over electromagnetism surprises even Frenda. However, Frenda soon lures Mikoto into an enclosed space. Frenda entraps Mikoto and uses her traps and weapons to attack her, but her efforts are later overwhelmed by Mikoto's powers. Seeing this, she blinds and deafens Mikoto with a stun grenade, and attacks her with missiles, knowing full well that the Electromaster's disability will only be temporary; but even then, Mikoto was able to dodge them easily due to her sensing the surroundings and using her power to escape. In response, Frenda attempts to befuddle Mikoto with indiscernible words, using the latter's confusion as an opportunity to toss a vial containing some chemical at Mikoto, who shoots it with lightning, resulting in an explosion. Frenda then bluffs her way into making Mikoto not use her powers, by releasing a fake chemical from the surrounding pipes to engulf their vicinity, and lying that it would explode like the vial if she uses her powers.

This forces Mikoto to a close-combat situation and is nearly overpowered by Frenda's superior fighting skills. Frenda however, angered Mikoto with her taunts, and retaliated by putting Frenda in an arm-lock from behind, and though this was easily countered by Frenda with a shoulder throw that threw Mikoto off, Frenda slips up as one of her electronic devices sparks one of the white tapes, making it explode, without igniting the surround gas around them; because of this Mikoto realizes Frenda's deceit and subdues. While trying to interrogate Frenda, Shizuri arrives and rescues Frenda. Mikoto retreats after seeing the sheer force of Shizuri's powers, as well as the involvement of Takitsubo Rikou, who consumes Body Crystal to track down Mikoto's AIM Field which enables Frenda and Shizuri to attack Mikoto after Rikou pinpoints her location. Both, Frenda and Rikou are later ordered to pull back after Shizuri realized she was fighting Mikoto, wanting to take her one-on-one. Back in their headquarters, Frenda converses with Rikou and shows her concern over her using her powers, and later wishes Rikou to find another place she will belong to, after Rikou replies that ITEM is the only place for her. Frenda later gets nervous after realizing that she forgot to collect her bombs, she is later told by Kinuhata Saiai that Frenda should prepare for punishment from Shizuri, after talking to her on the phone after Mugino becomes inconvenienced by Frenda's irresponsibility. It is presumed that Frenda gets punished after this arc, as Shizuri not only become inconvenienced by Mikoto using Frenda's bombs but also losing to Mikoto after using Frenda's white tape.

Silent Party Arc
In the anime original arc, they are hired by STUDY under false pretenses, being used as test subjects for their Powered Suits controlled by Diffusion Ghost. For that they desire vengeance for their reputation in the dark side of Academy City. The ITEM liaison gives them information on one of STUDY's factories, destroying several Powered Suits there. They are later present during the Silent Party, taking down several Powered Suits in a stadium, and inadvertently aiding Misaka Mikoto.

Frenda briefly reappears on September 2, while relaxing in ITEM’s private swimming pool together with the other core members of the organization.

Daihasei Festival Arc (Railgun)
As the opening day of the Daihasei Festival approaches, the committee tasked with gathering the seven Level 5s of Academy City contact Mugino Shizuri while she and the other members of ITEM, Frenda included, are relaxing in an indoor resort.

Abilities
Contradictory information is present between Toaru Kagaku no Railgun S and its supplementary material. She is listed, albeit discreetly, as a level 4 esper in an episode. However, in one of the DVD and Blu-ray booklet, her level and ability is not listed and she is spefically stated as "the only member of ITEM who fights without using an esper power."

The manga and novels make no reference to her abilities at all.

Other abilities
She proves to be skilled in close combat and is proficient with using an array of concealed weapons.

Upon her encounter with Mikoto, she makes use of electrical igniters and strips of a tape-like explosive to create fuses that can cut through various objects. She also connects fuses to dolls stuffed with explosives. In fact, this array of traps for Mikoto is a pre-planned trap Frenda set up throughout the facility, which transforms the area into a battlefield where she gains an upper hand almost at the first moment the fight begins. She normally uses remote-controlled bombs, but she chose to not prepare them against an electromaster like Mikoto in case they would be used against her.

She is also somehow able to conceal missiles in her skirt, possesses a perfume bottle of a vaporous, breathable Academy City-made explosive known as Ignis, and has a hidden stiletto in her left shoe. Unfortunately, she is prone to losing her focus in battle when she has the advantage, and she even admits that she underestimated Mikoto when the Level 5 Electromaster uses her electricity against a powerful insulator of electricity, ceramic.

Design evolution
Appearing only in a single volume, Haimura designed Frenda to be a simple moe character, and used her and the entirety of ITEM as a light contrast to dark premise of volume 15, up until much later when ITEM becomes more involved with the plot.

Quotes

 * (Railgun manga vol. 5) "Nishishishi~ ♪"
 * (Railgun manga vol. 5) "M-Mugino hugs a beat up old plush doll or she can't sleep!"
 * (Fighting against Mikoto Railgun manga vol. 5) "I said earlier that the target's life is of no interest, but I get a special feeling whenever I end them. That instant when you pluck a life, it feels like I've conquered their destiny. In the end...It's like they were born just to be killed by me."
 * (After Shiage accidentally shows her a porn video, vol. 15) “In the end, you’re disgusting, Hamazura”.

Trivia

 * Because of her tragic fate, Frenda is usually referred to by fans of the Light Novels as Fre nda (or フレ　ンダ in Japanese), with the deliberate space dividing her name in two. It acts as a joking reference for her death in the hands of Mugino Shizuri, who used her Meltdowner ability to slice Frenda in two by the waist.
 * Both the anime and the manga continue to reference the character's fate in the Sisters arc during her fight with Misaka Mikoto. Frenda comments both on nearly losing the lower half of her body to her own trap as well as the importance of preserving her legs. Also, when Mikoto numbed her tongue with electricity, that prevented her from selling out her team members, which she was perfectly willing to do. When she succeeds in doing just that in the Battle Royal Arc, Shizuri hunts her down for betraying them. In her last appearance of the final episode of Toaru Kagaku no Railgun S there is an contrail line passing over her waist.
