Record of a Night Too Brief (Bungou stray dogs OC story)

This is not an x reader or x oc story but it just follows my oc life and there is some romance and other things.
A little girl only the age of 6 awakened her ability, although it didn't have a good starting. Kawakami Sawako a criminal loved and looked up to by many other criminals around the world with a body count of 1040, most of which her murder and other cases of manipulative suicide(i made that up). She kills he victims is a very unpleasant way as most would say. her way of killing is that she sleeps with her victim in the form of someone that the victim has lost, either a woman or a man, and right after she kills them, her other way of killing is faster and other used when she wants to get things done, she uses her ability and sends the person to an eternal sleep(death). shes a sex addict.

bungo stray dogs' main plot is not mine nor are the character other then my oc and a little bit of the stuf i make up(like her backstory and so on)
