OMG, I think I've heard of Shonen Jump and I believe I did see a magazine about it at Books A Million at one point.
PS: I'm not a huge fan of yaoi like some people are. I'm more interested in Persona 5 Reader-Inserts, especially now since we have an evil version of Joker with us this year FINALLY after ten years of our messy-haired hero not having a dark version of himself for months! And he is so handsome! It's not hard to understand why I fell hard for him and chose him to love over the real Joker.
Shadow Joker appears briefly in the cinematic trailer for Persona 5 Scramble: The Phantom Strikers: www.youtube.com/watch?v=Opr0C_…
PSS: The Shadow's REAL name is My Dear Joker, but I like Shadow Joker more. I gave him the nickname because it just suits him better and he's a Shadow. Also, people are making fun of him using the N word, too, which I hate, like in this comment: Joker finally got his "N" pass and this one: He became the n word pass. Shadow Joker isn't 'BLACK'. He's just a really, REALLY dark gray color. And I HATE it when people use the N word because I'm African-American and I don't like how they use the word.
