Astral Buddy Chapter 5

**Yumiya Iruka** (弓箭入鹿, *Yumiya Iruka*?) is a student of Tokiwadai Middle School as well as the captain of the archery club, who is introduced in *Astral Buddy* manga. She served as the primary antagonist of the series's first half until reconciling with Hokaze Junko.

## Etymology

Like Yumiya Rakko, her family name "Yumiya" (弓箭) literally means "bow and arrow", an apt name for someone who knows archery. Her given name "Iruka" (入鹿) can be interpreted as "dolphin".

## Appearance

She has long wavy hair, which she ties with a ribbon at the back. Her fringes cover the right side of her face, and she also wears a traditional Japanese hair ornament, the kanzashi. As she is a member of the archery club, she wears the traditional garb for it. When wearing her Tokiwadai uniform, she wears stockings instead of socks.

The fringes that cover the right side of her face are so she can hide her scar and right eye which has a prism inside it, which she can use in conjunction with her powers. According to Junko's analysis, the way she looks including her decoration is to force people's attention away from the right side of her face.

## Personality

As an ojousama of Tokiwadai, Yumiya Iruka has a serious and refined personality to her, and is approachable by others. As the caretaker of her older sister, she is skilled at looking after others, though she shows excessive kinship. She also has a habit of subconsciously kissing others. However, Iruka has a more darker and cunning side, as she was able to successfully plan the abduction of Shokuhou Misaki. Though she prefers to take an advisory position, using trickery to defeat an opponent, she is willing to take part in battle herself if needs be.

Iruka displays an profound admiration towards Hokaze Junko, having looked up to her since their early days in the Clone Dolly Workshop. However, she also wants to surpass Junko but is disappointed by her holding herself back. Her failure to become a Level 5 in Ideal drove further into this way of thinking. Much of her actions in the Astral Buddy arc are done to force Junko to stop holding back her power and show how she wasn't wrong in looking up to her. She will not hesitate to sacrifice her own life in the process. She is also a secret fan of Gekota, thanks in part to Junko's influence.

Later, a more light hearted side to Iruka's personality is seen during her time reunited with Junko, as seen when she would blush heavily when Junko would give her attention and later enter into a comedic-friendly argument with her over Junko's past antics, showing that her friendship with her has more or less been mended. Iruka has also shown a level of annoyance and rivalry with Shokuhou Misaki over Junko's attention and is seen jealousy glaring at her during her and Junko's time recovering in the hospital after their duel due to Shokuhou's habits of teasing people and her own actions of purposefully showing off her close relationship with Junko to Iruka's face and her later claiming that Junko belonged to her, causing her to then get angry at Shokuhou due to her antics. She also sees Sogiita Gunha as a rival for Junko's affections upon his arrival in their fight against Houjou Seigo.

## 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. Mitsuari 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 Mitsuari 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 Mitsuari plateaued and Rakko remained a Level 0. However, despite her dream of surpassing Junko, neither of them actually became a Level 5. Later on, Iruka would discover that Ideal never meant to turn them into Level 5s and found that she had no talent in becoming one no matter how hard she worked for it. It would later be revealed that it was because that the true Level 5 powers development is only being given to one girl: Shokuhou Misaki.

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

## Chronology

### Astral Buddy

#### Astral Buddy Arc

*Main article: Astral Buddy Arc*
After being introduced by a teacher, Iruka teaches Kuroko and Junko archery. The teacher decides to turn the session to a contest between the girls where the winner gets a rare Gekota makeup poach, of which there is believed to be four prototype versions. During the contest Kuroko misses the bullseye and due to Iruka secretly interfering with Wave Conductor, Junko also misses her target, leaving Iruka the winner. Iruka wishes that Junko had taken it more seriously.

Afterwards, Misaki is incapacitated by a trap that Iruka had previously set up. Iruka and an accomplice approach. Iruka rejoices over the success of their plan, only to be caught by surprise by Makigami Komaki and tied up. Iruka's accomplice defeats Komaki, but is delayed long enough for Junko to arrive. Junko fights the accomplice, and during this fight Iruka is overjoyed at Junko's arrival but dissatisfied that she still isn't fighting seriously. Iruka breaks out of her restraints and threatens to attack Komaki, tricking Junko into saving her and hence being caught in a net trap. Iruka and her accomplice leave with Misaki, Iruka telling Junko to follow them but to do so alone.

Iruka and her accomplice flee in a truck, keeping Misaki in the back. They are unaware of Misaki being possessed by the ghost girl. They investigate the back of the truck after hearing a noise (the ghost knocking over a box of Indian Poker cards), but attribute it to the box falling over from the truck's movements, as the ghost has Misaki lie down and pretend to be unconscious. Iruka criticises her accomplice for not paying attention to her appearance. She then touches Misaki, apologises for dragging her into this and promising to free her afterwards, then kisses her on the cheek.

Iruka realises that Junko is tracking them via Misaki's phone. She takes the phone with her to lure Junko to an abandoned warehouse. The two of them talk, but Iruka refuses to explain the reason for her actions, and they begin fighting. Iruka manages to force Junko to retreat, but collapses in exhaustion and eats a glucose pill. She searches for Junko and finds an improvised bomb, which detonates and ruptures the roof's water storage tank. The resulting water hinders most of Iruka's attacks. Iruka tries one last attack but is still knocked down by Junko's attack. Iruka still refuses to give up as Junko has yet to use her true power. After explaining herself, Iruka unleashes a barrage of lasers from her prism eye. However, even this fails as Junko blocks the lasers with her body. Iruka faints, satisfied with Junko's power, and Junko catches her to prevent her hitting her head on the floor.

## Abilities

Yumiya Iruka's Level 4 esper ability is known as **Wave Conductor** (波動操作（ウェイブコンダクター）, *Hadō Sōsa (Weibu Kondakutā)*?, lit. "Wave Manipulation"), which allows her to freely manipulate sound, light, or anything with the properties of a wave. She can amplify them and focus them to achieve a variety of effects. Apparently, she has an easier time using her power when she's touching the source of the waves.

With her ability, Iruka can utilize sound waves in various ways. For example, by twanging her bowstring during an archery competition she messed up with the hearing of her competitor, causing them to miss. She can also use a whistle to create a sound blast. Iruka can also use her power to turn simple things like laser pointers and flashlights into weapons. Laser pointers are used as a ranged weapon to shoot beams of amplified light and burn through the target, while she uses a modified military flashlight as a light saber of sorts, which she calls *Kogara Sumaru*, able to easily cut through a steel beam. However, she cannot use her laser pointers and flashlight sword at the same time and must switch from one to the other. Because her powers cause the battery to run out faster than normal she carries several laser pointers and battery backups. Her tools, however, are all vulnerable to water, shorting out or being too wet for use.

However, even without tools such as lasers or flashlights, Iruka can create a bright strong flash of light out of her palm to send the direct stimulus into the brain of a target, causing an abnormality on their brain's electric signals and making them to pass out, bypassing individual sensitivity to photo-sensitive epilepsy, though the effectiveness varies from person to person and can be resisted if the target can control their own electric signals. Even a single finger from her attack was able to knock out Shokuhou Misaki.

### Prism eye

Iruka's right eye is a **Prism** (稜鏡（プリズム）, ***Prism***?), when applied with her powers she can turn the light around her into a laser. By overloading this artificial eye until it breaks and adding her own power, Iruka can shoot countless tiny lasers. Though each individual laser is weak, it is basically impossible to dodge. However, this is a one-time use attack that will also hurt her own body due the heat produced in her eye socket.
