Isekai Executioner: The Serial Killer in Another World

A murderer who cannot stop the urge to kill people, even though he wants to stop, receives the death sentence he wants. His joy is short-lived, as he is reincarnated in another world. The mission entrusted to him by the goddess is to kill 12 reincarnated people using his murderous impulses. Not all reincarnated people are saints!
