Chapter four of The Centennial Case: A Shijima Story, The River of Oblivion, takes you back in time to the events that follow the first murder you solved with Yoshino and Josui. We learn a lot more about the Shijima family and the legendary Tokijiku fruit in this chapter.

After the Incident Phase, you'll once again be in the Reasoning Phase to solve another murder, so gather your clues, come up with some new hypotheses, and figure out who the murderer is.

Warning — there are spoilers throughout this guide!

Throughout the Incident Phase, there will be times when you are posed various questions. The answers you choose have no impact at all, so we have not listed them in this guide.

How To Solve Gen'ei's Murder

Remember, when pairing clues to mysteries that not all of your hypotheses will pan out and many will contradict each other, it's up to you to find out the truth of the matter.

You don't have to complete every mystery in this section. Once you have created enough hypotheses, the purple 'Reasoning' tile will appear and you can choose to complete this phase and move on to the next.

We've got each mystery listed below in the order in which they appear, and have detailed all the clues you need for each one and where to place them.

Once you complete the Reasoning Phase, you move on to the Solution Phase. This begins with the Summary where Josui asks you questions and you use your hypotheses to try and build an idea of what happened. You only need to complete one set of questions and then you can select 'Finish Reasoning' to move on to the next part.

How To Identify Gen'ei's Killer

It's time to explain what happened to everyone involved and, of course, accuse your chosen suspect. Don't forget, if you make a mistake, you can simply retry. However, you will lose some points off your score for any mistakes made.

We have the correct answers listed in order right here:

  • The rope was tied securely
  • The killer didn't know Saeita was at the river
  • Eizan Shijima
  • The killer wasn't in Gen'ei's room
  • The kettle was used as a weight to pull the room
  • We were meant to hear the vase fall over
  • The ashtray must have caught on the rope
  • Eizan Shijima
  • His name written in the guestbook
  • His fountain pen was out of ink
  • Bloodstains on the tatami mat
