Well, Araki drew the cover art but Otaro Majio wrote and drew the nterior art, also, that fanfic is the most fucked up thing in the history of novels :

Stands are named after movies: NYPD Blue, Grand Bleu, The Rear Window, Singin' On the Rain, Dune, Face/Off, The Cube.

There are 36 Kars that live on the Moon, after Pucci re-started the Universe 36 times. One Kars, dubbed KArs-senpai by Jorge is good and helps them: he stole Kira's Killer Queen (Along with The World Requiem, D4C Requiem, Made In Heaven Requiem and Dune, which is Sandman's Stand) Kira is now a Spin user and uses a Golden Rectangle to amputate Lisa-Lisa's LEGS. He dubs himself Kira-Kira.

Doppio existss outside Diavolo, Diavolo swapped bodies with Giorno, and Giorno is trapped on a never ending death loop. Both Morio and Capri Island grow legs and skeedadle cooly after all this shit.

And then Kars-senpai's head becomes Jorge II (Joseph's father) Stand after he puts him on his chest.
