Background
She was part of Clone Dolly, a workshop created to make geniuses. One day, she and her older sister, Rakko, visited the Third Laboratory: Ideal, where they met Mitsuari Ayu and later Hokaze Junko. Iruka tried to approach her, but was told by Junko not to come close as she was a danger to others. Suddenly, Junko got a headache and she staggered next to the wall, cracking it. Ayu informed her that Junko became a Level 4 from a Level 2 in only two months, and Junko later proved her power by destroying a punching machine. Iruka was impressed by this, and Ayu told her that everyone admires Junko and the facility is meant to raise a Level 5. Hearing this, Iruka thought that she can be like Junko as well. From then on, Iruka's powers became more developed, while Ayu plateaud and Rakko remained a Level 0. However, despite her dream of surpassing Junko, neither of them actually became a Level 5.

Iruka later enrolled into Tokiwadai, the same school where Junko goes to.

Abilities
Iruka's ability is Wave Conductor (波動操作 (ウェイブコンダクター) ), which allows her to control waves of light and sound, amplifying and concentrating them. Through this, a twang of a bowstring can be amplified to startle someone, and a flash of light can be amplified knock someone out.

However, Iruka primarily uses her powers through a simple laser pointer and military flashlight, though not at the same time. Using her powers, she amplifies her laser pointer into an actual laser capable of at least burning the skin of a school suitcase in an instant. She can also use her laser pointer for rapid bursts of fire but at the cost of it breaking the laser pointer. With the military flashlight, she amplifies it to such a degree that she creates a light saber of sorts, which she calls , able to easily pierce through a metal beam. In her battle with Junko, Iruka carries with her several batteries on her person in case their power runs out.
