The Truth Album (真相畫冊) is the reconstruction puzzle: at the end of a case, you lay out the crime as an ordered chain of cards. The game's own description names the five stages, and the order is the answer.
That order is a genuine logic chain and not a formality. The madness activation has to come before the killing because the Disorder is the mechanism; the staging has to come after the killing because staging is by definition a response to it; and the forged alibi comes last because it is the layer that turns a murder into a locked-room murder. If you try to force a different order, the chain will not close.
Step 2 is where the disorder set pays off. A Disorder is not just a lens on the scene — it is a tool that was used. Your custom execution is keyed to the killer's specific disorder, which means that solving the album means correctly identifying (a) whose disorder it was and (b) how that particular disorder would be weaponised against a victim.
Scan the scene carefully, keep the five stages separate as you gather clues, and note which clue belongs to which stage — most of the mistakes people report are a clue filed under the wrong stage rather than a wrong deduction. The demo covers Chapter 1 in full, so the first album is available before you commit to the full game.
