Iizumi Rita

Leader (リーダー) (real name unknown) is a character introduced in Toaru Kagaku no Accelerator, a girl in a flu mask who leads Scavenger.

Appearance
She has short brown hair, and despite her normal appearance, wears a white flu mask with two dark crossed hands printed on it. She also wears a short-sleeved shirt, shorts, mismatched black tights and a backpack.

Personality
As the leader of the Scavengers, she reins in the oftentimes the excitable and vicious nature of her colleagues. She has a habit of recruiting anyone who looks promising or she has taken a liking to, as attested by her trying to recruit Accelerator despite being his enemies.

Background
Leader was abused by a teacher in her past, and as such has a strong resentment for them and "teacher's pets" as well, leading to her belief that eliminating them is justice. This is a trait shared with all the members of Scavenger.

Toaru Kagaku no Accelerator
When Rizou Nakimoto realizes that DA has become a problem, he contacts the Scavenger mediator to eliminate the group. The mediator wakes them up and announces them through an intercom that they have a job to do.

They succeed in not only destroying DA's forces but also killing several innocent Anti-Skill personnel. Later, after defeating DA's Tarantula, they come across Estelle Rosenthal and Hitokawa Hasami defending Yomikawa Aiho and Misaka 10046. As she and the other despise teachers like Aiho, they also despise "teacher's pets". With Leader calling the shots, Estelle tries to contend against them with Hasami. Scavenger however is too powerful for them despite all their efforts. It is not until the arrival of Accelerator that the tide of battle turns, with him making quick work of the Scavengers. Seeing him, Leader tries to recruit him, but is turned down and soon after, to her horror, discovers that they are up against Academy City's first-ranked Level 5, freezing up completely despite Yakumaru's efforts to snap her out of it. After the other Scavengers are easily defeated, Leader is left alone before Accelerator, wetting herself out of fear before passing out.

Dream Ranker Arc
Leader participated in Scavenger's operation to track down the robotic doppelganger of Kuriba Ryouko, in order to improve Scavenger's situation after their previous failure. After locating the doppelganger, they proceeded to the Shinasame University DNA Map Analysis Laboratory, only to find the doppelganger gone, though Leader was confident it wouldn't escape her eye. They caught up with the doppelganger after she confronted the original Kuriba Ryouko. Once the doppelganger was captured, she sent Seike after the original Ryouko to verify that they hadn't switched, before taunting the doppelganger over her appearance and possible desire to be a real human. In response, the doppelganger partially broke free and grabbed Leader's arm before snapping it. In considerable pain, Leader was spared from having her eye plucked out when Naru's attack smashed the doppelganger open.

Abilities
Leader's esper ability is Level 3 Predator (鳥瞰把握 (プレダター) ), which allows her to look for a target, apparently with no regard for distance. When she uses Predator, she covers one of her eyes, and as the ability activates she sees numerous eye shapes in the sky. When the target is found, the eyes move toward that direction. Effectiveness of the ability is reduced during the day, however.
