Joemaru

Joemaru is the slash ship between Jou Tazuna and Ranmaru Kageyama from the Your Turn To Die fandom.

Canon
Uh, none? They don't interact in canon. Ranmaru is aware of Joe, as he was given the information that he was Sara's best friend and a non-participant.

Fanon
They met in the afterlife and are now dead bfs. Change my mind.

Aside from that, theories have risen that Joe is connected to a lot of people in the game, with the idea that the policeman Keiji killed was his dad, and he was the brat in Kanna's flashback that got yelled at by Kugie for making Kanna cry, which wasn't the case.

Ranmaru knows some minor information about Joe, and Joe has no idea about Ranmaru. Ranmaru referred to him as Joe, but since they'd canonically never met and weren't friends, it's proper Japanese etiquette that Ranmaru refer to Joe by his last name, Tazuna. This may just be for the translation or aluding to some kind of affiliation with one another.
