The dank cell was quite disgusting. It had moss and rust all over the walls and bars. But Dio could clearly see that literally every other cell was clean and lit up by lanterns. A woman next to his cell just got released and she was thanking the guards profusely for something.
The cellmate that Dio was stuck with was some sort of robber who had to get a knife surgically removed from his chest about a week ago. He's currently going through with his sentence of about 20 years in prison. Something about robbing a bread store or something.

"Zo, what're 'ou in fer?" The man says pointing over at Dio.

"That's some weird accent you have there, how much of school did you have to skip to get that." Dio says uninterested.

"Listen, I'm not 'ere fer your opinion."

"You're literally the one who asked the question." Dio responded dumbfounded at this guy's stupidity.

"Yea? And zo what?"

"..."

Dio decided to ignore the man and his ramblings.
Dio then sees a man with leopard checkered pinkish crimson hair being escorted to a cell. His shirt seems to be a mesh of complex wires and his pants are studded.

"Get in." The guard says pushing the mystery man into the cell with Dio.

"There's many other cells here, why not put me in one of those?" The mystery man asks.

"This cell is for the more.. Untrustworthy individuals we've caught." The guard says pointing to claw marks on the wall that Dio had yet to notice.

The guard then turns around and exits the room. Many of the other chained up prisoners start to yell, laugh, and rattle chains furiously. The noise drowned out Dio's thoughts and he could see that it was the same for the mystery man. The ground rumbled in wake of the ruffian's squabbling. The bread robber was banging the wall with a rusty spoon for no apparent reason.

"... Listen, I can get us both out of here. For a fee of course." The mystery man says."I'm painstakingly low on this world's currency, so it'll help me out a lot."

"I could break out of here at any time, it's just that going through with that trial later tomorrow will help my overall plan." Dio responds.

"Mmm. You seem awfully familiar to me.. You've got the general aura of someone I knew back where I came from..
Are you perhaps related to a boy named Giorno Giovanna?" The man asked.

"I need some more information on this.. Giorno.. What does he look like? What kind of powers does he have?
And I'm going to say this right now, are you a Stand user?" Dio asked bluntly.

"So you're from Earth. My name is Diavolo, the boss of a group called 'Passione'." Diavolo explained.

"Dio Brando. And by showing that you could figure out I was from Earth from the expression 'Stand' alone tells me that you have one.
Please tell, what's your stand's ability?" Dio asked sitting down on a rickety bed.

"I won't tell you my ability. But I will say that it's name is「King Crimson」" He explained.

"Likewise, and it's「The World」."

"Anyways, I want to know what you know about Giorno. He has golden hair and he has a stand power that allows him to turn non-living object into a living thing."

"No, I appear to not know the boy you speak of." Dio responded.

"Hmm. At least let me in on this plan of yours?" Diavolo asked.

"Listen, I've turned one of the army's horses into a zombie. This will, in turn, spread an infection of my minions in the city without anyone knowing.
I'm going to go to this 'trial' and chew out the king and his guards in front of the whole room, making him seem like the bad guy." Dio explained.

"I asked you the question out of curiosity, but I thought you wouldn't answer. So why are you telling me, a stranger, this. And there's even another person in here." Diavolo asked.

"I want you to help me. Stand user to another Stand user. I want to create a party of Stand users and strong people who pledge their loyalty.
I already have Jotaro, I have a strong druid back at the village, and then you'd be a fine member." Dio explained.

"... What a devilishly good idea." Diavolo said." I'd be better to be on the side of another Stand user, rather than be at the receiving end of one of your Stand blows."

"Now, we just wait...
Wait, where is Jotaro anyways?"

Little did Dio know, he was literally right on top of his head.

"Yare yare daze.."

"So why are we at a courthouse again?" Giorno asked.

The courthouse was massive, it could hold at least 100 people in a large cinema styled row of seats. The seats were also set in a C shape and were sectioned off from the main area in the middle.

"If we want to know a lot more about this world, we can learn a lot from criminal cases. It shows a new wild variety of different places and weapons and people." Bruno explains.

"I think it's just fun looking down apon the criminals on trial." Josuke says sipping an apple juice carton.

"Where did you get that?" Mista asked.

"There was a vendor- sip -outside." Josuke sipped.

"ORDER!" The judge said.

The judge had a long grey beard and was pretty old, but you could see the look of determination in his eyes.

"The king himself will be observing this case, as he thinks this is a personal matter.
This case is currently being held by prosecutor G. 'oultee. May God bless this mess." The judge says bringing down his hammer.

The king is now clearly seen in a seat next to the judge with his daughter, Holly, right behind him. The lights were dim, as this was taken place during the night and the lanterns let off a distinct yellow light. The team readjusts themselves in their seats before the session will officially begin. Josuke snaps his fingers to get the group's attention and pulls out multiple large buckets of popcorn. All of the buckets were covered in melted butter except for one, which was oversaturated with salt. He then passes these buckets along the row giving one to each person, starting with Okuyasu who was sitting right next to him. The group stared in awe for a second before deciding it's best not to ask where these came from. Okuyasu looked down at his salted popcorn and Josuke handed him a carbonated drink.

"HOW DID YOU EVEN AFFORD THIS?!" Narancia asked staring directly at the bucket.

"SHH. It's starting!" Mista says passing some popcorn to Number 6.

"I, G. 'oultee, will start off with my statement." The prosecutor announced.

"Yes, please begin." The judge agreed.

"The criminal, not currently out here yet, is being charged with:
Using magic of the dark arts.
Murder.
And potentially being an undead."

"Undead..?" Josuke says leaning back in his chair slightly taking a handful of popcorn.

"Bring out the man!" 'oultee yelled rolling the R.

A bunch of obviously jacked guards wheel out the prisoner, who is sitting down with his head in his arms. He is rocking back and forth, the only distinct thing that anyone could make out about this man from their distance was the obvious blonde hair that strikingly resembled Giorno's. It was also apparent that nobody was representing him, meaning that the judge could rule a punishment without ever hearing his side.

"That seems.. Biased." Bruno said chomping on some popped corn.

"The evidence is here: He was first found out by the Church that he was a possible undead, so his majesty sent his daughter with a guard to easily take care of the problem that was residing in town Greymorre. But more days passed and she didn't come back to the capital, so everyone got worried. We sent a bunch of royal guards to go investigate and we brought her back with no trouble. However, what's more disturbing is the fact that her guard suddenly vanished, and when we asked her about it she merely said that no guard came with her. If that's not all, she was also a different person when she came back. She displayed a higher form of empathy towards goblins and undead creatures, which is unnatural for a member of the Holy Church. She seems to still be under some of the effects, so we'll show you what we mean. Your highness, please let down the princess to the stand." The prosecutor explained.

Holly stood up from behind her father and went behind a curtain, which she then emerged from behind a door frame down near the stand.

"! Lord D-
It's you! It's been a while." Holly said happily apon spotting Dio.

'This is all going to plan.' Dio thought.

"As you all heard, Holly spouted the word 'Lord' when addressing this man. As if she were talking to someone she's known for a long while.
And as for the fact that this may be just his status, that would be incorrect. This man is the Mayor of Greymorre, but not the standards of being a 'Lord'."

"That's just mean.." Number 3 says chomping on some popcorn.

"Lock him up!" The crowd around us start to chant.

Just as the judge seemed to raise his hammer, the group wanted to get up and interject, but was also interrupted by the man in the cage.

"It seems like you'll find me guilty. So with that being said, may I speak my final words before being locked up?" Dio says starting to stand up.

Dio is now seen at his full height, which was pretty tall and muscular at 195 centimeters.

"Let him." The king said with a stern look."It's the last thing he had to look forward to before being executed."

"They were going to kill him?!" Narancia whispered into Mista's ear.

"I would like to say that there are no grounds for any of these bases. Where's the physical proof? Are you just going to agree with your king solely because he said so? Give me a single witness, a single photo or video that hasn't been provided by the king. If the church are the ones who sent Miss Holly to my town, then why aren't they here? You are literally just drones that follow only what is being told to you. You have no freedom, and you have no rights in the presence of the king. He has all the power in the whole country, and because of that you're afraid of every breath and step you take around him. If you accidentally muck up his shoes, he could send his assassins to kill you in your sleep in the most vile and disgusting ways you can imagine. At any waking moment you also worry that taxes shall rise due to some crappy reason that was given to you by the collector."

"Shut him up." The king barked at the guards.

The guards went over and plunged their spears into Dio's neck and face. Blood went flying as the spears went in and out of newly made holes in his skin.
But Dio kept talking.

"See? He allowed for me to speak, but the minute I start to talk about him, he orders to kill me.
This reminds me of a crucial part of history.. Oh, that's right.
After the american revolution, France went broke and taxed every last dime out of the Third Estate. Every single noble and rich person did not mind this, because they weren't being taxed even a penny's worth, even normally without the raised taxes. The price of bread also went up to about the amount of a month's work. So people got mad and stormed the Bastille and broke into the palace of Versailles. After the king succumbed to his selfishness and tried to flee his own country to join another, which the people didn't like. So the king was slaughtered using a guillotine.
Do you get what I'm saying? If you keep abusing your power like this, someone with take notice and overthrow you. In fact, I think that sometime real soon you will be murdered." Dio went on.

"H-he won't die! He's an undead!" The guards start yelling.

"「The World!」"
