This is a mafia au, characters can be aged up but at the same time. It's sorta going to be in a twenty - thirty era mixed with modern times.
There can be stands in this but at the same time you don't need to :D.

ALSO I DO NOT KNOW MUCH ABOUT MAFIA STUFF SO DO BARE WITH ME PLEASE

~Scenarios ~

1. Oc has worked for one of the mafioso familia as you do your job keeping up with everything. One day while doing your mission you ran across crush. You two have met before just never really talked. But you worry more about your mission since you know what would haven if you don't do your job.

2. Oc works at a bar / strip joint where a certain mafia groups hang out at. Cleaning tables and taking orders was one of your job.The other was to make sure people didn't get into fights. Which is what happened when crushes group runs into an enemy one. Having to now intervene before it gets brutal.

3. Oc is a singer, having been new to their job. Oc wasn't told that mafia members came to the bar/ strip club they worked at. While performing a song while giving the dancers a break. Oc noticed the group walking in. While still sining you noticed crush staring at them. When making eye contact and quickly looking away. Crush was now interested with crush. Now wanting Oc to be their pet, they were willing to do anything.

4. Oc works for (which every mafia) but your a rat. Working for the other side secretly or you work every close for the boss. Telling them about people who dare cross their path or try to take them down.

5. Oc works at an strip club as one of the dancers. It was quite normal for members of the mafia to show up. You get lots of tips from the mafia members that come and go. Which you were making a pretty wealthy business out of it. While oc was performing one of their dances , crush walks in with their group. Watching oc for a bit, oc makes eye contact with crush. Which soon gets crushes interest, Crush wanted you now.

6. Make your own scenario

My Oc's in this au
(If they're apart of the mafia )

Usami

Usami originally worked in the joestars before being moved to the zeppeli's. She never really minded the whole moving to this mafioso familia.
She's a recon and a medic

Shi

Shi when she was younger in the crusaders familia has been an informant. Growing up and having kids she decided to have the idea of maybe dropping out. But when she left she was told she was needed a year later. She was hesitant at first but went back making sure her kids were in safe hands after all.

Now that she's back she has been moved to the zeppeli's familia and is now a espionage.

Momoka

Momoka has been an outcast for most of her life, and from her parents. When she was younger she was friends with josuke and been closed to him ever since. When he became godfather he asked her if she would want to join. She gladly accepts.
She's an informant and a hacker for them. (She even helps with bandaging and makes new inventions for them)

Yua
(When she joins the mafia she would be an informant)

Her mother and older sister refuse for her to be apart of the familia as they are scared she could get in danger. Due to them both being in the mafia or just puts Yua in more trouble. So she works at the bar trying to keep a low profile. When ever she joins she joins the Passone. (She sings)

Yua'a work outfit

Marina

Maria was once in the zeppeli's mafioso with her mother but soon was tranferred to the passione famila. She never really minded it due to them being able to see each other as non enemies.
She's an extortion

Irene

Irene was mostly my versed for this, taking missions from anyone. She was known as the peoples hitman . Having do things for people when they're having troubles, always for good never for the wicked. She would always help them. She never planned on join the mafioso until she ran into the Joestar familia. Hearing them out and their bargain , help bring the people to justice who slashed her eyes, she gladly joins. After all they can't take back on what they said.
She's an hitman
