Yoshihiro Kira

"I will kill anyone who harms my beloved son!"

- Yoshihiro Kira,

Yoshihiro Kira (吉良 吉廣) is the secondary antagonist of the fourth part of JoJo's Bizarre Adventure, Diamond is Unbreakable, introduced in the "Atom Heart Father" story arc.

Yoshihiro is Yoshikage Kira's late father, turned into a Ghost. Despite Yoshikage's violent inclinations, Yoshihiro is fiercely protective of him. Yoshihiro attacks the Joestar Group with his own Stand, Atom Heart Father, and later creates several Stand users with the Arrow to try to assassinate the group and protect his child.

Appearance
Yoshihiro Kira is a ghost, having the appearance of a lightly-built, balding old man. Yoshihiro has a small mustache and a goatee of dark hair.

While he was human, Yoshihiro is shown to have modest, respectable attire; consisting of a striped green button-down shirt with a purple tie, yellow cardigan, and a loose-fitting lime-green suit. As a ghost, however, Yoshihiro now only wears his striped green shirt with matching pants.

Personality
He is extremely devoted to his son and takes supporting him and his ambitions to the extreme, even going as far as to protect his son's serial killer lifestyle. There is evidence that his son Yoshikage inherited his malignant soul from him, as Yoshihiro utterly disregards the women his son has killed from his youth and the fact that Enya and DIO saw fit to entrust him with the Bow and Arrow.

Abilities
Yoshihiro Kira remained as a ghost in a camera when he died and is able to trap people into the space photographed by the camera. Able to move inside the photo, anything he does inside will translate into the real world.

Background
At some point, Yoshihiro marries an 🇺🇳 and has a son with her named Yoshikage on January 30, 1966. He appears close with his wife, but also distant. The two were unlikely to have any major fights. However, his wife was essentially abusing their son while Yoshihiro would turn a blind eye to it.

Several years before Part 4, Yoshihiro obtains a Stand Arrow from an old woman in Egypt. He uses it to awaken his Stand Atom Heart Father as well as Killer Queen in his son.

Yoshihiro dies of cancer before the events of Part 4 when his son is 21 years old, with his wife dying shortly after him. Regretful of not doing anything to stop his wife from abusing their son, his Stand enables him to remain in the mortal world to help protect his beloved son and let him maintain his "normal" life. In death, he discovers the existence of the Ghost Girl's Alley and tells his son to not look behind him in case he goes there.

Diamond is Unbreakable
Josuke, Okuyasu, Koichi, and Jotaro first meet Yoshihiro when they investigate Yoshikage Kira's house for clues to discover where he is hiding. In the process, Yoshihiro uses his Stand Atom Heart Father and takes a picture of Josuke and Jotaro, trapping them with him. After calling his foes just to tell them they are going to die, Yoshihiro takes a knife out of a drawer and decapitates Jotaro and Josuke in the picture, threatening to subject them to the same fate in the real world. However, Jotaro takes a close up picture of Yoshihiro so he can no longer manipulate his surroundings. Jotaro closes the photo, tapes it and tacks it against a column. Yoshihiro pretends to suffocate but Okuyasu Nijimura then adds even more tacks to spite him. Yoshihiro then uses this to pretend he can escape through the holes made by the tacks, bluffing Okuyasu into opening the photo to check. Using a string from his pajamas, Yoshihiro pulls himself out of sight. He then snatches the Kira's Arrow from Josuke and leaves, tied to a crow.

To assassinate the heroes, Yoshihiro decides to awaken as many Stand users, impelling them to thwart the efforts of Josuke and Rohan to find his son as a kind of payment. He thus turns Ken Oyanagi, Yuya Fungami, Tama, Masazo Kinoto and Terunosuke Miyamoto into Stand Users. Witnessing Ken's rock-paper-scissors' battle against Rohan Kishibe, Yoshihiro inadvertently helps Rohan when he photo flies into the window of a truck that was about to crash into the mangaka, making the truck swerve. Also drawn to Mikitaka Hazekura, Yoshihiro doesn't pierce him however, as the Arrow bounces off against him. He also collaborates with Toyohiro Kanedaichi in order to trap Josuke inside of Super Fly by acting as a bait, but this plan is also foiled.

Eventually, Yoshihiro finds his son having murdered Hayato Kawajiri. This is an extremely unfortunate timing since the Joestar Group has taken an interest in the boy and plan to interrogate him. Yoshihiro suggests that his son flees Morioh but Yoshikage adamantly refuses to cave in. Yoshihiro's Arrow suddenly pierces his son. This awakens the Bites the Dust ability of Killer Queen.

Nonetheless, Yoshikage Kira accidentally lets Josuke safely discover his identity and is forced to fight him. During the fight, Yoshihiro manages to slip himself inside of Hayato Kawajiri's jacket, allowing him to communicate Josuke's location inside of a house since Yoshikage could not see him without entering Crazy Diamond's range. Unfortunately for Yoshihiro, Josuke discovers his ploy and snatches the cell phone he was using to tell his son where Josuke was. By whispering, Josuke manipulates Yoshikage into using one of his air bombs to blow up Yoshihiro, killing him by incinerating the photograph he was in.

JoJolion
In the Alternate Universe, Holy Joestar is married to a man named Yoshiteru Kira instead of Sadao Kujo, who seems to be Yoshihiro's JoJolion counterpart, and like in the original universe, he is the father of Yoshikage Kira. It is unknown whether he even has a Stand in the SBR Universe. It is hinted by Kyo Nijimura that he is dead, as she states that she and Holy are the last members of the Kira family.

All Star Battle (PS3 Game)
Yoshihiro appears as the stage hazard on the Kira Estate stage. He brandishes a knife and uses it along with his Stand, Atom Heart Father, to attack players, traveling along a curving path.

Eyes of Heaven (PS3/PS4)
Yoshihiro appears as a special trait for "Kosasku Kawajiri" in Eyes of Heaven. When Kosaku reaches his last health gauge, Yoshihiro appears and begins following opponents for 30 counts of the battle timer. This enhances the properties of Kosaku's "Contact Bomb" and "Impact Ignition Bomb" skills, referencing Yoshihiro's role as a guide for Yoshikage's air bombs near the end of Diamond is Unbreakable.

Trivia

 * Yoshikage Kira's backstory was not included in the manga. Yoshihiro's wife was in essence abusing their son but Yoshihiro would ignore it. After Yoshihiro becomes a ghost, he goes through all the trouble to protect his son because he felt bad for what he did. Kira's backstory wasn't included in the manga both because it was serialized in a magazine for a younger audience and Araki felt Kira would end up being a very sad villain so readers wouldn't see him as the enemy.
