Whenever night falls, the heinous people on the assassination list will disappear quietly if the mission entrusted to them is assassinated.
Every second day, people in Gotham City will find the bodies of those who seem to be bad for Gotham City exposed in their original places.
Rumors leaked that the person who did this was wearing a dark blue dress. His movements are neat and elegant, and he behaves like an aristocrat.
So, people called him——
"The Prince of the Dark Night"
