JosuYasu

Josuyasu is the SLASH ship between Josuke Higashikata and Okuyasu Nijimura from the Jojo's Bizarre Adventure fandom.

Canon
Josuke and Okuyasu met originally as enemies while Josuke and Koichi were out walking together

Fanon
Fans of the ship tend to take advantage of the open-ended conclusion of Diamond is Unbreakable as neither of the pair permanently died.

Trivia

 * Kohei Ashiya, an animator director, drew art of the two for Kiss Day 2018 of Okuyasu kissing up to Josuke and having to be held back, along with Valentine's Day 2017 art of him in tears calling Josuke a "traitor" for receiving Valentine's Day chocolate from others, despite Josuke not appreciating the attention from his female classmates.
 * In the anime adaptation, Josuke and Okuyasu used a romantic connotation of love when talking to each other, technically meaning that they've canonically professed their love for each other.
