Kakyoin Noriaki

Kakyoin is a young man of above-average height and a fit build. He is typically seen wearing a slim-fitting long gakuran, but also wears striped pajamas during his initial encounter with Death Thirteen. In the anime, he additionally 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 admirers commented on his looks and during the Tower of Gray encounter, he swooned two female stewardesses. Upon arriving in India, he is also referred to as beautiful 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

Noriaki Kakyoin is first introduced as a cruel, uncaring 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, and as thanks toward Jotaro for saving his life. Kakyoin is 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 is 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 can 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. Even as a hero, he can be particularly cruel to his enemies, as seen when he rips Tower of Gray to pieces without hesitation and takes revenge on Mannish Boy by forcing him to eat his own excrement.

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 heart, making them feel at ease.
