Requirements

This is a very rough guide for now - just enough to clarify what's needed to meet the requirements of the category. I'll follow up with a baseline route once I have a run uploaded to support it.

Please note that this guide, and the category rules, contain extensive spoilers for the whole game.

You can see the requirements for a valid run in the category rules. You must unlock all 10 case files, uncover the additional 2 conspiracies, and achieve the following, and only the following, convictions:

• Akiko, 2 convictions: Henry's Escape, Who Killed the Holy Seal Marshals?
• Carmelina, 2 convictions: The Murder of Grace Bloodlines, Carmelina's Conspiracy
• Lydia, 1-2 convictions: The Second Holy Seal, Who Killed the Holy Seal Marshals? (Optional)
• Sam, 2 convictions: Who Opened the Third Seal?, Who Breached the Fourth Holy Seal?
• Witness, 2 convictions: The Mystery of the Dead Killer Demon, Witness's Conspiracy
• Yuri, 5 convictions: Henry's Demonic Possession, K. HX is Missing, The Second Holy Seal, Who Opened the Third Seal?, Who Breached the Fourth Holy Seal?
• Dainonigate, 3 convictions: Who Opened the Third Seal?, Who Breached the Fourth Holy Seal?, The Crime to End all Crimes

(Note: While Lydia did not kill the Seal Marshals, she did breach the first Holy Seal. Whether it's a glitch or not, the game convicts her of this crime when she confesses after Sam's conviction. As far as I'm aware, there's no way to avoid this and still convict Yuri of all of his crimes. If a way to do this is discovered, that run will be valid, so long as no other convictions are added or missing.)

Any run that has the above, and only the above, convictions at the end of the trial will be valid for this category.

Finding the case files

You have to get all 10 regular case files to get the correct convictions. There may be more than one way to open each case file, but one possibility is:

1. Talk to Judge to unlock The Crime to End all Crimes and K. HX is Missing
2. Talk to Akiko via Starligh to unlock Henry's Escape
3. Get the vault records from the library to unlock Henry's Demonic Possession
4. Open Grace Bloodline's grave to unlock The Murder of Grace Bloodlines
5. Inspect the dead marshals to unlock Who Killed the Holy Seal Marshals
6. Talk to Shinji by the Second Seal door to unlock The Second Holy Seal
7. Inspect the Third Seal to unlock Who Opened the Third Seal?
8. Inspect the Fourth Seal to unlock Who Breached the Fourth Holy Seal?
9. Inspect the killer demon to unlock The Mystery of the Dead Killer Demon

One possible trial

There may be more than one way to achieve this result. There may also be evidence requirements that are not listed here. But one way to get the required convictions is with the following accusations:

1. Akiko
2. Yuri
3. Carmelina
4. Akiko
5. Yuri
6. Yuri
7. Sam
8. Dainonigate
9. Witness
10. Dainonigate
11. (And then both Carmelina and Witness' conspiracies.)
