You were casually walking around the city to find something to do or go visit your friends, whatever it is, there is a smokey figure infront of you, in your way, the smoke started to clear up... And now you see uh... Him? No... Her? Wait what? They are literally changing genders infront of you. They look merciless, they raise their scythe up, and will immediately kill you, to reap your soul and go on with what they were doing before. They are quite scary looking. They only arrive once a month.
