This is a list of all the AUs that Rosewick can be put into (though if you AU hard enough, anything is possible XD).
PS: You might need to know the background of some of these series.
PPS: Can be prompts for fanfics or fanart or, heck, even edits.
Kougami x Akane Version: Ruby is the new Inspector and Roman is one of the Enforcers assigned to her. Roman used to be an Inspector, but after the murder of his sister/best friend and fellow Inspector Neo, he goes insane, clouding is hue and turning into an Enforcer. He is determined to find Neo’s killer. He helps Ruby as she gets used to her new job, and they eventually form a close bond. As she spends more time with him, Ruby can see Roman’s crazy determination and worries he might go overboard and defy the System she used to believe in.
Ginoza x Akane Version: Ruby will still be the new Inspector in this version, but Roman will be the other Inspector she is working with. Roman won’t be as helpful and most likely just teases Ruby as she tries to get used to the workplace, though he gets serious when the situation calls for it. As both of them and the rest of their team work together to find the person responsible for the rise of criminal activity, Roman slowly loses his way, and it’s up to Ruby to help him keep his hue clear.
Ruby is the new police officer recruit, and currently the one being talked about. She graduated early from the police academy and then got recruited into one of the most prestigious police forces in the continent. She values justice and peace above all else, and works very hard to keep the city safe. One of her “just” actions takes it too far, and she almost gets fired. The chief gives her one more chance, but this chance is a challenge. She has to get to the bottom of a series of missing Faunus – a case which no one has a lead on. Along the way, she “enlists” the help of a conman named Roman (and his associate “child” named Neo), and they work together to solve the case.
Roman is the god of the underworld. He likes to stay away from the other gods’ discourse and just watching over his realm. The goddess of death, Neo, stays close by his side. He isn’t so alone with her around. However, one day, Roman notices the goddess of spring (Ruby) near one of the entrances to his realm. He watches her warily at first, but day after day, she would come and just enjoy frolicking in the meadow, making flower crowns for her beloved sister, the goddess of harvest (Yang), and Roman would look forward to whenever she came near. He enjoyed seeing her smile. One day, Ruby became curious and walked closer to the entrance, unbeknownst to her. She eventually stumbles upon it and goes in. Roman confronts her and tells her to go. Ruby goes, but she comes back the next day.
Seven mages are chosen to participate in a battle royale in order to win the Holy Grail and have a chance to get their wish granted. Roman is one of these mages. He is a melee fighter, but can also use fire magic. He summons Ruby Rose of the Red Riding Hood (Lancer class), the hero who defeated thousands demonic wolves and saved a whole country. Roman knew that Ruby was going to be a great fighter and would therefore make the War easy, but he didn’t know that she was such a short and childish servant. Maybe it’ll be a challenging fight after all.
Maybe even go into mature territory if you add the “magic circuit recovery” aspect ( ͡° ͜ʖ ͡°)
