For the past few days,Serena had mysteriously disappeared without a trace as she and her Black Rose Dragon (Lucine) had went on a mission to Vacuo,you would have soon started to head towards Vacuo to find her and her dragon to see of they are alright and bring them back home safely,Once you made it to Vacuo you would have seen a figure that looked to be a Dragon like faunus as she hums a little while a few grimm were laying on the ground in defeat underneath her while you were also able were able sense a powerful aura radiating from her

(You don't know that this is actually Serena and Black Rose Dragon fused together as one)

(Also if anyone is planning taking this one into 18+ territory,That has to go to PMs of if anyone is planning to take it to that)
