I really like this story. The best parts about it are for sure 1 - The way you do the characters, all of them are on point. Especially Joseph (which is very important cause he's the main character). When i started this i was wondering if you're gonna be able to do him justice. He's heroic and noble, but also goofy, lazy and a bit of a jackass. He's really smart, but also really stupid. So i was wondering if a fanfiction would be able to write him well. But i gotta say that you nailed it, Araki himself might as well have written this. And 2 - i love how you integrated the Jojo lore into Remnant. Makes the story so much cooler to have all these counterparts.

I hope to see the continuation, so many questions i want answered. Like how DIO and Diego are related. And how exactly DIO transported Joseph to Remnant. The why seems simple enough, he probably just wants Joestar blood to complete his transition into Jonathan's body (which is obviously in "short supply" in Remnant), but considering that he somehow seems to have a Super Aja perhaps his ambitions go way deeper than that (another question i am looking forward to have answered is how and why he has a Super Aja in the first place.) And i am definitely looking forward to seeing the origin of the stone daggers. Considering it seems to transform people into vampires using some kind of Grimm juice or some shit, Salem or the God of Darkness himself are likely culprits, but then that begs the question of how Ozpin wasn't aware of them before Speedwagon clued him in.

I just knew that Penny was going to look up and end up seeing that star the moment you brought up the Big Dipper. Though with all the flags you're throwing, like Penny dressing like a Zeppeli and her now seeing the Death Omen star I gotta wonder if she will actually survive in this fic. As Joseph showed in this very chapter, it's possible to see that star, live to tell the tale and stop seeing it.

I appreciate you showing little stuff like Joseph's world having a lower drinking age and more modest swimsuits. Most crossover fics, not just RWBY ones just crossover fics in general (hell, even official crossover material written by professionals), well... they just plop someone into an alien world and pretend like it's all the same. This attention to detail really adds a lot.

Very interested to see where this story goes with Cinder's plans now that Mercury's and Emerald's covers have been blown. Also I'm taking note how you explicitly say that Joseph is from a "parallel dimension", I think those are the exact words that are used for D4C's ability. So I guess this is just among the many parallel dimensions of the jojoverse, which might mean that D4C might have access to it, so I wonder if Valentine will get involved somehow. Maybe this Diego even is from Valentine's world and he ended up here somehow, and everyone just thinks he's a faunus. I did find it strange how this world has two Dios - as Diego and vampire Dio seem to be separate people. So maybe this world only has the one and Diego is actually a foreigner.
I appreciate you skipping the food fight since you weren't planning to do anything different with it.
Also, nice Baoh reference.

Soooooo... no one noticed that Joseph doesn't have Aura? And they just casually said "Oh he's gonna bleed out!" as if that's a normal occurrence in sparring and they aren't protected from serious injuries by their Aura. Well, on that topic, Joseph also hasn't noticed the presence of Aura? That his clackers didn't actually damage Ruby at all and that unlike him she isn't bleeding? Cool story so far that but is a huge oversight.

That hand prank was actually funny. It even got me. I thought you were gonna use it as an excuse to give Joseph a robo hand or something.

Damn so Joseph finally decides to cross paths with Dio, I mean it was basically destined but now the real fun begins. Can’t wait until we see more

Why dont you write a fic about that by yourself instead of asking him to write for you

I am so glad you decided not to give Joseph a harem. But I beg you, make Velvet at least some love interest to Joseph! Like they have some fun at one point and then Joseph manages to return home, Velvet’s got a kid and she names him Josuke and on some ancient Faunus language, it means “Joe” so we get Josuke Scarlatina!

To nantono,vanessa masters and zero:…FOR FUCK SAKE STFU!

You DID NOT just make Penny do the nazi salute, did you?

looks like Yang is similar to Josuke when their hair is insulted or ruined

is this Remnant version of Jonathan Joestar?

I wonder if this story is dead

... DIO!

mess with Yang's hair, you're Dead.

insults Josuke's hair, You're super dead
