Yoshihiro Kira

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

- -Yoshihiro Kira

Yoshihiro Kira (吉良 吉廣) is an antagonist featured in Diamond Is Unbreakable.

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 fancied 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.

History
Yoshihiro gets the Stand Arrow from an old woman in Egypt.

He dies of cancer before the events of Part IV when his son is 21, his wife dies shortly after him. His stand enables him to remain in the mortal world to help protect his beloved son and let him maintain his "normal" life.

He uses the arrow at some point to awake Killer Queen, presumably after the Sugimotos' slaying of 1983 since their corpses are not blown away. Kira is 17 durig this event.

Yoshihiro, in his death, goes in the alleyway and learns of the girl residing in without recognising her, he then tells his son to not look behinf him in case he goes there.

Diamond Is Unbreakable
Josuke, Okuyasu, Koichi, and Jotaro first meets Yoshihiro when they investigates Yoshikage Kira's house for clues to discover where he is hiding. In the process, Yoshihiro attempts to imprison and kill them with his Stand abilities, but only manages to imprison Josuke and Jotaro. However, Jotaro is able to make Yoshihiro occupy so much of a photo that he can no longer manipulate his surroundings. Undeterred, Yoshihiro escapes with the Arrow and awakens several Stand users, impelling them to thwart the efforts of Josuke and Rohan to find and stop Kira as a kind of payment. When they fail and/or move to Josuke's side, Yoshihiro and Kira are at a loss on what to do until Yoshihiro's Arrow pierces Kira. This awakens the Another One Bites the Dust ability on Killer Queen.

Nonetheless, Kira accidentally lets Josuke safely discover his identity, and so is forced to fight him. During the fight, Yoshihiro flits about in secret to communicate to Kira how to direct Killer Queen's incendiary bombs. Unfortunately for him, Josuke realizes this, and so is able to bait Kira into detonating a bomb right next to Yoshihiro's photograph, causing him to cease to exist as the photograph burns up.

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 herself and Holy are the last members of the Kira family.

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