So are you ready to take on the role of the aspiring detective and solve the mystery within The Centennial Case: A Shijima Story? Time to crack this case wide open. The first chapter, The Wandering Mummy, takes us back to 1922 when a private auction for people seeking to prolong their lives has a much more lurid ending.
This chapter will introduce you to the basic mechanics of the game, during the Incident Phase you will watch scenes unfold and gather clues, which you can then use to create hypotheses in the Reasoning Phase. You don’t have to click on each hint as the scenes unfold , as all of these are automatically added in the reasoning phase independently. Once you have sorted out your hypotheses in the solution phase, you can proceed with the story to unmask the killer.
Warning: Plot spoilers and murder mystery are contained in this guide!
There are several times when you will be asked to answer a question during the Incident Phase and after you identify the killer. These answers don’t really matter or change the story, which is why we haven’t included them in this guide.
How to Solve Setsu’s Murder
I would have already had a short tutorial on the reasoning phase earlier in the chapter, but essentially you need to create hypotheses by matching the clues to the red mystery tiles . You don’t necessarily have to complete all of the mystery tiles, as once you’ve created enough hypotheses, the purple “Reasoning” tile will appear and you can proceed with the game.
Your hypotheses are exactly that, proposed explanations, so they are not necessarily the actual facts. Many of your hypotheses will conflict with each other and it is up to you to decide the most likely series of events during the solution phase.
Just below you will find each mystery in order, as well as the clues necessary to create each hypothesis. Please note the exact wording, as some tracks have very similar names.
