Frenda Seivelun

Frenda Seivelun (フレンダ＝セイヴェルン) is a member of team ITEM. She is one of the main combatants of the team, though not having any apparent esper ability of her own, she makes up for it with her incredible prowess in close-combat, as well as expertise in traps and concealed weaponry. Her full name is revealed to be Frenda Seivelun, whereas before she was only known as Frenda. It is also revealed she has a little sister by the name Fremea Seivelun.

Appearance
She is a girl with blonde hair and blue eyes. Her outfit consists of a black, tight-fitting sailor top and a pleated skirt. She also wears a pair of white pumps and dark-colored stockings. 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 blood-thirsty nature, indicating that she enjoys taking away the life of someone as if she was destined to end them.

 * Main article:Level Upper Arc

She and her teammates are first seen during the climax of the Level Upper Arc. Where they are in Joseph's Coffee and Restaurant arguing whether or not they should go into a public or private pool since it's the summer. They later hear the Level Upper treatment program on the P.A. System, unaware of what's exactly going on and waking up a Takitsubo Rikou.

Sisters Arc

 * Main article:Sisters Arc

Frenda and ITEM reappears during Mikoto's rampage on research facilities related to the Level 6 Shift, here they are seen continuing their argument between public and private pools, 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 other's 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 a enclosed space. Frenda traps 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 befundle 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 counterd 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 Clear 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 incovenienced by Frenda's irresponsibility. It is presumed that Frenda gets punished after this arc, as Shizuri not only become incovenienced by Mikoto using Frenda's bombs but also losing to Mikoto after using Frenda's white tape.

Later events in the novels
Out of fear of being killed by Kakine, she sells out ITEM to SCHOOL and hides, but Mugino catches her and she is executed.

Abilities
In spite of being the only member to lack any psychic 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 a tape of whiteout and an electronic device to create a fuse that can cut through various objects. Usually, the fuses are connected to dolls with explosives within them. In fact, this array of traps for Mikoto is a pre-planned trap Frenda set up herself throughout the facility which transforms it into a battlefield where she gains an upper hand almost at the first moment the fight begins.

She is also somehow able to conceal missiles in her skirt, and has a hidden stilleto in one of her shoes.

Unfortunately, she is prone to losing her focus in the battle when the advantage goes to her side and she even admits she underestimated Mikoto when the Level 5 Electromaster uses her electricity against a powerful insulator of electricity, ceramic.

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.
 * She has the habit of oftenly using the word "basically" when speaking, her younger sister has a similar trait.
 * Along with her sister, she is one of the very few non-Japanese science side characters in the series, the only other two being Stephanie Gorgeouspalace and Thomas Platinaburg.
