Killa-Queen

Yoshikage Kira (吉良 吉影 Kira Yoshikage?) is the main antagonist of Diamond Is Unbreakable.

Kira is a paraphilic serial killer committed to defending his uninterrupted lifestyle.

Kira is also featured centrally in the short story Dead Man's Questions

Appearance:

Kira has light, loosely combed back hair with a few strands out of place. He wears a light suit and a dark tie patterned by a column of skull emblems with upright, cat-like ears, similar to those on his Stand, Killer Queen. As a salesman by profession, he wears a similar suit throughout the series, though he usually takes off his jacket at home.

Personality:

Kira is a serial killer, characterized as highly egocentric and psychopathic, with a few obsessive-compulsive tendencies. He is also a hand fetishist.

Kira longs for a peaceful life, safe from any worry, and does not wish for it to be interrupted. Whenever that peaceful life seems assured, Kira adopts a jolly and confident demeanor. Although he is highly intelligent and possesses many talents, this yearning shows in his dislike of coming in first, and he even made it a point to never rank better than 3rd in any competition so as not to stand out. Since his youth, Kira has been avoiding standing out, living a healthy life. He becomes bothered when someone disrupts his habits and goes to extreme lengths to get it back. As his father pointed out, this will to stay in the background was so bad that if bullied or denied his favorite toy, Kira would bite his nails until they bled, being the only way he's found to express his frustration.


STAND: KILLER QUEEN

NAMESAKE: Song by Queen

Destructive Power: A
Speed: B
Range: D
Durability: B
Precision: B
Developmental Potential: A

Appearance:

Killer Queen is a humanoid Stand of a height and build similar to Kira's, or slightly more muscular; light in color overall.

Its crown is flat, while two sharp, triangular shapes resembling a cat's ears stand on either side of the top of its head. Its eyes comprise cat-like vertical pupils in front of generally light-colored sclera. It has no nose. With thin lips, its mouth is perpetually closed.

It wears dark, studded, leather-like forearm-length gloves, mirrored in style by a garter belt-like band at its waist and ankle-height footwear. Its thumbs are additionally bandaged in white. Four short spikes line the top of its back.

Its shoulders, the back of its hands, belt buckle, a plate hanging in front of its crotch, both sides of its ankles and the top of its feet all bear the emblem of a skull with ears resembling its own; in varying sizes and external decoration.

Later, the space behind its stomach is revealed to be hollow and suitable for storing an object.

Abilities:

Killer Queen is a short-range humanoid Stand of average to above-average speed and melee attacking power. Its unique ability involves planting or targeting up to three kinds of bombs, usually capable of completely consuming their targets; though their explosions are neither normally harmful to more than one target, nor perceptible to non-Stand users. The main drawback is that only one bomb can be active (and only from one of the following bomb types).

Primary Bomb (Bomb Transmutation)

By touch, Killer Queen may charge any object as a bomb. If a charged object is touched, the charge travels from that object into the whole of a target before exploding and (usually) destroying it completely. Kira may also detonate this bomb at any previous point. However, only one bomb can be maintained at any given time

Secondary Bomb ("Sheer Heart Attack")

Sheer Heart Attack (シアーハートアタック Shiā Hāto Atakku?) is Killer Queen's second type of bomb, featured primarily in the arc Sheer Heart Attack.

In appearance, it is as a sphere, plated, with a superficial, removable knob on its top; standing on the treads of a tank at its sides; embedded in front by a cat-skull similar to those appearing on Killer Queen's body, with the addition of a downward dagger on the forehead, an articulate jaw, and a short spike as a nose.

This bomb detaches from Killer Queen's left hand, of which it is part. It is completely autonomous, with an unlimited range. It seeks out whatever the warmest thing in the vicinity is, then induces an explosion there, with a power proportional to the heat of the target. The body of Sheer Heart Attack is totally indestructible (withstanding countless blows from Jotaro's Star Platinum). As an autonomous fighter, it has no special weaknesses. As part of Killer Queen's hand, any external effects ascribed to it are transferred to Kira's hand

Tertiary Bomb ("Killer Queen Bites the Dust")

Killer Queen Bites the Dust (キラー・クイーン バイツァ・ダスト Kirā Kuīn Baitsa Dasuto?), more simply known as just "Bite the Dust" (負けて死ね Baitsa Dasuto?, kanji lit. "Lose and Die"), is Killer Queen's third type of bomb; featured primarily in the late arc Another One Bites the Dust.

Kira is granted this ability when Yoshihiro Kira's Stand-creating Arrow pierces him a second time. It is born from Kira's desire to prevent anyone from knowing his true identity.

This bomb appears as a miniaturized form of Killer Queen that hides within whoever it is planted on, acting independently of Kira's will, manifesting only when the bomb is triggered. In the only example shown, it is planted on Hayato Kawajiri. When someone interrogates Hayato about Kira, the bomb enters their field of vision, along with their eye; before inducing an all-consuming internal explosion.

Secondly, until Kira finds out who the bomb killed, he lets a temporal loop occur after the killing; from one hour to one day earlier. Because Bites the Dust is completely independent and autonomous, Kira is not informed about who gets killed, nor is he aware of every time loop. In fact, the only person who retains memory of each time loop is the person that is the trigger. The time loop causes anything that happened in a previous loop to happen again, even if someone tries to prevent it the next time. So, even if the victim doesn't interrogate Hayato on this occasion, Bites the Dust will still kill them at the time recorded before. Only when Kira is confident about who died will he let time flow normally.

Thirdly, because the person on whom this bomb is planted must be alive in order to activate the trigger, Bites the Dust will not harm the person in anyway during the explosions, nor will it let the person be harmed from other forces, such as when the miniature Killer Queen prevented Hayato from slitting his own throat with a knife to prevent anyone else from dying. It also appears to be able to revive that person after death, as seen when Hayato was alive once more after Kira had accidentally killed him in the bath, implying that time was relooped to prevent Hayato from dying and also making it so he was not destined to die again the same way.

If Kira wishes to use Killer Queen, since he cannot maintain more than one potential bomb at a time, he must cancel Bites the Dust. Therefore, the only way to stop Bites the Dust's destiny to kill someone from a previous time loop is for Kira to cancel it before the designated time of death. Also, Hayato discovers that Bites the Dust only works on non-Stand users, such that Kira can only tell a non-Stand user his secrets to enable the ability

Air Bomb Transmutation ("Stray Cat")

Finally, Kira carries Stray Cat in an opening in the stomach of Killer Queen. With Killer Queen's Primary Bomb, charging Stray Cat's condensed air bubbles, Kira may create invisible, speedy projectile air bombs (空気弾 Kūki-dan?). Although he cannot see these bombs, he is skilled in determining their trajectory using basic mathematical skills.
