Noriaki Kakyoin

"I don't really want to face DIO again, but... let's just say you opened my eyes... that's all."

- Noriaki Kakyoin upon joining the Joestar Group,

Noriaki Kakyoin (花京院 典明) is a primary ally featured in the third part of the JoJo's Bizarre Adventure series, Stardust Crusaders. He also appears as a posthumous secondary character in the spin-off manga Crazy Diamond's Demonic Heartbreak.

Kakyoin is a Japanese student who was brainwashed by DIO during an earlier trip to Egypt and is sent to kill Jotaro Kujo. After being freed from DIO's influence, he decides to join Jotaro on his quest to Egypt to save Jotaro's mother and find redemption. Kakyoin is a Stand User and wields the long-ranged Hierophant Green.

Appearance
Kakyoin is a young man of average to above-average height and fit to slender build. He is typically seen wearing a slim-fitting long , but was also shown wearing striped pajamas during his initial encounter with Death Thirteen. In the anime, he wears the pajamas when admitted to the hospital.

Kakyoin keeps medium-length hair, characterized by a large, twisting bang hanging before his face. He wears cherry-shaped earrings: each is a long, fine arch, tipped by small spheres.

He is considered handsome and has captured the attention of a few women. One of Jotaro's own admirers commented on his looks and during the Tower of Gray encounter, he swooned two female stewardesses. He is also referred to as beautiful upon arriving in India by a man trying to sell him a tattoo.

Later, Kakyoin acquires two thin scars vertically crossing both eyes from Geb, which he often hides with a pair of dark sunglasses.

Personality
Noriaki Kakyoin is first introduced as an evil and cruel teenager because of DIO's brainwashing. Thus he remorselessly attacks unrelated civilians and adopts a might makes right mindset. However, he reveals himself as a righteous, though blunt individual. Kakyoin is ruthless with his enemies but loyal to his companions.

His reason for joining the Joestar Group is for both fighting evil, as he mirrors Jotaro's own explanations for saving his life, and of course a sense of debt toward Jotaro for saving his life. Thus Kakyoin is also a brave individual, willingly participating in the dangerous journey to Egypt, and is also able to keep his nerves even in the direst situations such as having been punched through by The World.

Kakyoin is noted by Araki to be "the honor student type", and thus can be described as haughty and somewhat introverted. Though he normally keeps a polite and somewhat formal behavior, Kakyoin is a rather cold and prideful man. He hates bowing down or brown-nosing. The humiliation of having been weak enough to bow to DIO was a part of his motivation for seeking redemption and revenge during Stardust Crusaders.

Kakyoin mentions he could never relate to people because of his ability, and thus never desired to make friends for most of his life. He thinks only respectable individuals are able to be friends of his. The Joestar Group is the only group with whom he has attached himself, but he cares very strongly for them. Araki himself mentions that if it weren't for their Stands, Kakyoin and Jotaro wouldn't have been friends. Kakyoin has shown to lighten up with Polnareff, although he can also be very brutal and vindictive, having elbowed Polnareff too as a "reconciliation". His attitude is notably worse with his enemies, whom he frequently threatens and belittles, and during his fights, he is very ruthless against them. Both as a hero and an antagonist, Kakyoin is particularly violent as he remorselessly kills all of his opponents (ripping Tower of Gray without qualm ), arguing that they were evil beyond redemption; moreover he viciously takes revenge on Mannish Boy by forcing him to eat his own excrement, the first and only time he took exception.

Kakyoin has stated that if he were to fall in love, he would fall in love with someone like Holy, who gives off the feeling that anything will be alright and can calm anyone's hearts, making them feel at ease.

Stand
Kakyoin's long-range humanoid Stand is Hierophant Green; able to extend tentacle-like limbs or unravel to a modest extent; as well as fire a barrage of hard projectiles (an "Emerald Splash"). He is often seen shouting his signature attack (like the Emerald Splash) in fights.

Mastery
Kakyoin is, due to a lifetime of possessing Hierophant Green, quite proficient at using it. Although it is mostly seen as a humanoid, Kakyoin states that its true form is that of a bunch of strings; as such one of his key tactics is to secretly unravel Hierophant Green's tentacles while keeping the main body as a distraction. Thanks to that, Kakyoin can infiltrate bodies, suddenly avoid attacks by unraveling his Stand, use the strings as ropes, and even perform piercing attacks. However, Hierophant Green's otherwise straightforward Emerald Splash does not lend itself to imaginative use of it.

Gaming
Kakyoin is skilled at playing video games, expressing confidence about beating Telence T. D'Arby in the racing game F-Mega. After making the rookie mistake of not boosting his car at the starting line, he recovers from this and shows off his skills by performing a spin attack against D'Arby in order to regain a foothold against him. While in the speedup tunnel, Kakyoin is able to ride against the side of the wall, as well as maneuvering the turns and hazards of the tunnel while in complete darkness. He utilizes his power meter to knock D'Arby completely off the racing track.

Allies

 * Jotaro Kujo: Like with Avdol, Jotaro's relationship with Kakyoin begins with a fight. After defeating him, Jotaro takes Kakyoin to his house to remove DIO's flesh bud and release him from DIO's control. Jotaro and Kakyoin later develop a strong friendship, discovering a mutual interest in sumo, and Kakyoin being one of the few people Jotaro smiles at. Kakyoin sacrificed his life to give Jotaro an advantage against Dio and Jotaro mourns his death along with Joseph and Polnareff. In the JOJONIUM special interviews, Araki comments that without their power, Jotaro and Kakyoin probably wouldn't have become friends.
 * Joseph Joestar: Having joined them on their journey to Egypt, Kakyoin got along well with the rest of the group. While his interactions with Joseph specifically were minor, Joseph usually went to him to crack jokes and express his comedic nature (due to Kakyoin being able to tolerate it the most). Towards the end of the series, Kakyoin's last act before dying was shooting the clock tower with his Emerald Splash, in order to help Joseph discover the secret behind The World's ability to stop time. Joseph, whilst hiding his grief, responds by treating the message with utmost importance and swearing that Kakyoin's death would not be in vain.
 * Jean Pierre Polnareff: The two worked well together in battles such as Hanged Man and The Lovers. The two did have a brief falling out when Mannish Boy attacked the gang with Death Thirteen and Polnareff didn't believe Kakyoin when he said the baby was the stand user, believing the journey had taken its toll on Kakyoin and made him crazy. However, upon learning that Kakyoin was right, he genuinely apologized and the two have gotten along since. Kakyoin notes that it is thanks to Polnareff knocking him out while he had his Stand out is what let him save the day. While in a sinking submarine, the two were still able to joke around with each other and do a manly handshake. At the end of their journey, Polnareff mourned his comrades, including Kakyoin.
 * Muhammad Avdol: Kakyoin first interacted with him during his recovery after DIO's flesh bud had been removed. With both of them having adequate knowledge on Stands, the two proved useful to the Joestar group in every battle. Like Polnareff, Avdol's alleged "death" impacted Kakyoin and he swore to avenge him. While this would turn out to be a front by the rest of the group to fool Polnareff, Avdol, likewise, considered Kakyoin as a valuable comrade and even discouraged Jotaro from gambling his soul in Daniel J. D'Arby's game of poker.

Enemies

 * DIO: Having met DIO on a holiday in Egypt with his family and then put under his control with a Flesh Bud, Kakyoin was loyal to him and would do anything he wanted. However, upon having the bud removed by Jotaro and seeing the harm DIO was causing towards the innocent Holy Kujo, who had shown him kindness as he was recovering at the Kujo residence, Kakyoin decided to go with Joseph, Jotaro, and Avdol to Egypt to defeat DIO.

Creation and Development
Kakyoin's first name was originally intended to be "Tenmei" and is still used by Araki himself, despite it officially being "Noriaki". The change was the result of a miscommunication between Araki and his editor as the kanji can be read both ways. This can also be seen in Enya's hotel register, where Kakyoin wrote "Tenmei Kakyoin".

Kakyoin is seen incorrectly wearing Polnareff's earrings several times throughout Part 3. This includes Chapters 160, 164, 172, 182, and 183.

Casting
According to anime producer Nobutaka Kasama in the 2020 Anime Expo interview about the anime series, the "rero rero" of Kakyoin was particularly difficult for Daisuke Hirakawa (the voice actor for Kakyoin) to pull off since it was to be repeated 17 times and so he had to train himself out of work (for instance rehearsing repeatedly during bathing).

Kakyoin's voice actor in Heritage for the Future (along with several other characters in the revisions of the game),, would later go on to voice Part 8 Josuke Higashikata in All-Star Battle and Eyes of Heaven.

Kakyoin's voice actor in the Stardust Crusaders Drama CD, Sho Hayami, also voiced Enrico Pucci in All-Star Battle and Vanilla Ice in Heritage for the Future, the Part 3 Anime, and Eyes of Heaven.
