A failed assassination attempt, a bank account full of lives, and a handful of friends that were most likely the only reason I made it out alive. What else is there to go wrong?
---------
'Aviana Borguese' was the city thief in her past life. She worried little regarding the state of the world, and often found amusement watching the children of the most elite families cry over their stolen playthings.

Now, this low-life thief was reincarnated as an elite, professional mage fighter in an entirely different world. With more money than she knew what to with, and a lot of lives to play with, her worries were all but figments of her past.

What is she to do when a Vanguard Soldier calls for her head while simultaneously catching the attention of the assassin from her prior life?

She has a choice: to survive the hellfire rained down by the Isekai world creators and defeat them, or let the world fall and seek revenge when faced with her killer.
