The tentatively-named Josuke Higashikata is the main protagonist of Part VIII: JoJolion.
Josuke is a young, handsome and physically fit man of above-average height.
He constantly wears a tasselled "Dixie cup" sailor cap (in multiple illustrations, adorned with the same palm as Jotaro Kujo). He wears a striking sailor suit, cut with a wide neck and above the navel; a neckerchief adorned by a button resembling a slotted screw head; large emblems of an anchor on his right side and a compass rose on his left; fitted pants with belt, and a pair of high-top athletic shoes.
Josuke has diastema between his upper incisors, a star-shaped birthmark on his left shoulder, and four testicles. He has two sets of irises and two tongues, joined as one, differing in texture and hue/shade; the left halves lighter.
Yasuho Hirose mentions a resemblance to her dog, Josuke.
The establishment of Josuke Higashikata's true name, history and identity represents one of the principal forces in the plot of JoJolion. His provisional name is given him by Norisuke Higashikata IV.
A primary investigation yields the tentative name of Yoshikage Kira, but this likelihood quickly comes into doubt after a visit to an apartment registered by this name and the subsequent interrogation of Sasame Ojirou.
Upon return to Josuke's place of discovery by the Wall Eyes, he and Yasuho discover the corpse of a second man, identified upon autopsy as Yoshikage Kira. A DNA test of Kira's corpse commissioned by Yasuho reveals a very close match to Josuke's makeup, as well as the return of the cryptic statement that the two in fact represent the "same person". Later still, Kyo Nijimura proves that Josuke is a fusion of Yoshikage Kira and another unidentified individual by indicating a physical seam along both of Josuke's eyes and his tongue, while explaining how they would have been fused by reference to a mysterious property to the earth near the Wall Eyes.
