Rain Code Ch 0 | Massacre on the Amaterasu Express

Welcome to our walkthrough for Rain Code Ch 0 | Massacre on the Amaterasu Express in Master Detective Archives! Our hero Yuma awakens in a strange room with no memory of who he is or what he’s doing there. With only a note and ticket for passage on a train, Yuma heads for the train in hopes of figuring out what’s going on.

??? (Train Station)

Select whichever difficulty you’d like as it does not matter. All will result in the same outcome! When you gain control of Yuma Kokohead, interact with the items listed below in the storage room to earn 10 Detective Points each. After that, you are free to go outside via the door.

  • Cardboard Box
  • Back of the Room
  • Shelf with Umbrellas
  • Items Scattered on Shelf
  • Toy Robot

Once you’re in the hallway, Yuma will reflect on the room he was just in and you’ll be presented with three choices. Choose the Station’s Lost and Found option to receive 30 Detective Points, increasing your Detective Rank to 2.

Amaterasu Express Car 1

After a brief cutscene, Yuma will find his way aboard the Amaterasu Express. You’ll then be shown a tutorial on how the notebook works and given the main objective to find the Master Detectives in the train. Start by Interacting with the below objects on the train car to get 10 Detective Points from each one and fully explore Car 1.

  • Guide Map
  • Train Door
  • Connecting Door
  • Main Control Room A
  • Restroom
    • Mirror
    • Window
    • Toilet Door

Hurray! You found the other Master Detectives! When you regain control of Yuma, speak with the people listed below.

  • Detective wearing the black hat with ears
  • All 5 of the Master Detectives
  • Zilch a second time
  • Pucchi

After getting to know your fellow detectives, Yuma will be presented with three choices:

  • About Amaterasu Corporation
  • About Kanai Ward
  • About the Amaterasu Express

Select each one to learn a little more about the situation and they will also reward you with 10 Detective Points each.

After another cutscene, Yuma will ask himself who is the most suspicious person on the train. You’ll only get to pick one and each choice rewards 10 Detective Points which should get you to Detective Rank 3. The choice doesn’t matter so pick who you want (I chose Yuma).

To wrap things up speak with Zange to learn more about his Forte. Now make your way to the infirmary in Car 1.

Amaterasu Express Car 1

Approach the infirmary to trigger an event where you’ll be introduced to the Objective Display 2 tutorial.

Train Station

When you make it off the train, another cutscene triggers. After it ends, you’ll find yourself in the Mystery Labyrinth leading to another cutscene.

Rain Code Ch 0 Mystery Labyrinth

During the cutscene, you’ll earn Solution Keys and will also receive a tutorial on the Playable Loop. When you regain control of Yuma, Shinigami will task you with solving the Amaterasu Express mystery!

Reasoning Death Match

Start off by following along the long unending hallway until another cutscene triggers leading to a Reasoning Death Match. You’ll need to dodge the word coming at you until the phrase You’re the only one who could’ve done the crime! shows up. Rebuttal it to counter the statement (the game will load the Inflammable Statement for you this time). You’ll then have to go through another round of dodging words until And only pretended to drink it! shows up. Rebuttal it with the Thoughtography Image solution key. This will bring a close to the Reasoning Death Match.

Mystery Labyrinth Options

Continue to head down the hallway to trigger an event when you reach the door. You’ll come to a fork in the road so to speak and be introduced to the Mystery Labyrinth Options mechanic. The question presented to Yuma will be Was the culprit one of the six?. The door to the left will say “Yes” and the door to the right will say “No”. You’ll want to head through the door that says Yes.

Reasoning Death Match

Congratulations! You’ve chosen the right door and your prize is ANOTHER REASONING DEATH MATCH!!! The table below has the Inflammable Statements you’ll get in order going top down with which Solution Key you’ll need to use to rebuttal the claim. Counter both statements with the Solution Key to emerge victorious!

Mystery Labyrinth Options

Once again continue heading down the long hallway passing through the doorway at the end. This will trigger another event leading to your second fork in the road posing the question Everyone was dead, so how did the culprit pull it off?. Follow Shinigami to the right door then head over to the left. This will trigger another event where Shinigami will lead you through the correct door! Proceed down the hallway (let’s see how many different ways I can say that!) until another event triggers introducing the concept of Dead Ends. After another event, you’ll be placed back at the fork. Head through the Commit suicide after the crime door.

Mystery Labyrinth Options

Venture on down the correct hallway until yet another event occurs. Yuma will fall through the floor landing in a mine cart that will take off speeding down the track. You’ll then be asked a series of questions that you’ll need to answer correctly to continue the investigation. Those questions and their answers are listed in the table below. Answering all the questions correctly will bring you to the goal!

QuestionAnswer
Who was the last person to die during this incident?The Culprit
Who set fire to the dead culprit?The Culprit
Who was the last person to be burned to death?Zilch

Reasoning Death Match

After another cutscene plays out, you’ll be given two options: “Open the conclusion door” or Demolish the conclusion door. You’ll want to follow Yuma’s gut and choose the latter option to demolish the door. This will lead to one last Reasoning Death Match where you’ll be introduced to the Noise mechanic which obstructs your vision of the statement. You’ll need to use the Solution Balde to cut through them. You’ll also get a capped bonus for each Noise you destroy. With that in mind, use the below table to finally take down the Mystery Phantom Swank. Also note that in each round, there will be multiple Inflammable Statements, but only one is Rebuttable.

Crime Scene Re-Creation

Thanks to Shingami’s punch to the face, you have a chance to re-examine the Infirmary from Car 1 on the train. Inspect the two items below to gain a pair of new Solutions Keys.

  • Cushion
  • Burned Blanket

Shinigami Puzzle

With this new evidence, Shinigami will start her puzzle game to help Yuma with the case. You’ll be given a question and have to fill in the missing letters hangman style before the time runs out. The letters you’ll want are as follows: R – E – D. This will solve the puzzle and you’ll now be able to loot the treasure chest for a new Solution Key! Now backtrack to the “wrong end” from before. After a short time, you’ll be given two options (Z*OM and EV*C) and Shinigami will teleport you back there to save time. Pick whatever option you would like to continue.

Solution Key Selection

Finally nearing the end! This final section is kicked off by introducing the Solution Key Selection mechanic where you’ll need to use the correct Solution Key to open the door to the truth!! Interact with the door and choose the Red Herring Solution Key to break the lock. Head through and follow the new path…

Mystery Labyrinth Options

…until it starts to fall apart and Yuma must jump onto different floating stones to reach safety! Answer the questions correctly as you go to reach the other side triggering an event.

QuestionAnswer
Was what Yuma saw through the window actually Zilch?Yes
Was the burnt corpse in Car 1 actually Zilch?No
Zilch swapped places with the corpse in the infirmary…Before Yuma entered

Spot Selection

You’ll now be introduced to the Spot Selection mechanic where Yuma will have to deduce where the corpse was hidden. You’ll want to select under the sheet on the bed. This will return you to the hallway for another cutscene which leads to…

Reasoning Death Match

A REASONING DEATH MATCH!!! There is only one round this time and the Inflammable Statement you want will be the third one. After rebutting it, you’ll win this Reasoning Death Match and begin climbing up a ladder.

Mystery Labyrinth Options

When you reach the top, you’ll find yourself on top of the train. Chase after Zilch until you reach the end of the train. This will trigger another event placing you on the track. Follow along the track until you reach the fork where you’ll be presented with a question: When moving the body from Car 1 to Car 5, the culprit… You’re two answers are “Moved through the train” or “Did not move through the train”. You’ll want to choose the Moved through the train option. Know what comes next?

Yep! A REASONING DEATH MATCH!!! You know what to do!

Shinigami Puzzle

After the Death Match, you’ll pursue the phantom down a hallway via cutscene which leads to another Shinigami Puzzle. This time the sentence you’ll need to complete is The main control system was lost when Car 1 was _ _ _ _ _ _ _. Choose the letters D – E – T – A – C – H – ED to solve the puzzle then continue pursuing the phantom! You’ll get a bit down the hallway when another puzzle appears! The body was transported along with the entire _ _ _. Choose the letters: C – A – R to solve the puzzle leading right into another…

Reasoning Death Match / Shinigami Puzzle

REASONING DEATH MATCH!!! Time to take down the phantom once and for all! Use the table below to rebut the phantom’s Inflammable Statement. Once that’s done you’ll kick off a Shinigami Puzzle to close the investigation.

Inflammable StatementSolution Key
There’s no way to shuffle the train cars around!Route Map

The question for the puzzle is From the start, the Amaterasu Express was a _-car train. Select the number 4. After solving the puzzle another cutscene will trigger and you’ll end up back in the long hallway. Follow it to the end then take the stairs all the way to the top to reach the fort guarding the truth.

Last Stand

Approach the fort to begin your assault!!! The area will transform sending you to the desert where you’ll begin the attack aboard the Great Onset Destroyer! Charge at the fortress kicking balls, tackling through walls and jumping over the spikes. After a while, you’ll come to a wall with the phrase There’s no evidence they ever swapped! on it. Use the Distorted Plate Key Solution to smash through it. Once you reach the fort, you’ll need to use a solution key to destroy the fortress. The phrase You have no hard evidence proving that location was the first car! will be on the front of the fort. Use the Bloodstains on Interior Lock solution key to bring down the fort! To wrap up the case you’ll have one last Spot Selection. Choose Main Control Room A when prompted to begin the Deduction Denouement.

Deduction Denouement

During the Deduction Denouement, you’ll have to piece together everything to show the full picture of the crime that has transpired. To start only a couple of the Solution Keys are available with more unlocking as you place them in the correct locations. The table below lists which solution key goes on which page. When you’re done a scene will play out going through the whole incident.
