A murder occurs in a city.

It was considered a simple case, but as murders using the same method occur one after another, it spirals out of control.

Eventually, people came to call these incidents the 'Jack the Ripper case'.

People discover a commonality in that the 'Jack the Ripper case' occurred only in the 'Sullivan Family's' territory, and they begin to suspect Sullivan.

As the interrogation intensified, Sullivan ordered his enforcers, Ripper and Lobelia, to find the real culprit behind the 'Jack the Ripper case' in order to quell the unrest.

And then, victims of 'Jack the Ripper' appear.

[ The People Surrounding Jack the Ripper ]

We do not know who 'Jack the Ripper' is.

However, there are countless people that Jack the Ripper points to.

Never miss the suspicion that builds up in the characters' actions and conversations.

• Become the 'Reaper' and enter the rough world of the Mafia to chase the real culprit who murdered Lobelia.

• Do not miss anything suspicious in the characters' actions and conversations. It is up to you to decide who to suspect.

[ Repetition and Mastery ]

Who was your most threatening enemy?

As you go through repeated battles and deaths, weigh who to eliminate first.

• You are not a hero. The enemies' attacks will be fatal in one way or another.

• The specially upgraded gun holds only two rounds. Use intelligence, and sometimes quick reflexes, to take out your enemies.

• Break through the Mafia using your own clear formula forged through death.

[ Memory and Record ]

Was there anything suspicious?

Was there anything you wanted to remember?

Lobelia told me to write a diary every time that happened.

• Record any suspicious occurrences from today in your 'log'.

• 'Interrogate' the suspect based on the log to get closer to the truth.

• Find the real culprit through interrogation and punish Jack the Ripper, who murdered Lobelia.
