MAMIYA: Complete Walkthrough: 100% CG and Achievements Guide

After rereading the game so many times and watching others do so as well, I decided to write a complete walkthrough guide + CG and achievement paths, with the least amount of spoilers as possible.
To be honest, if you explore all choices (which I recommend) you’ll eventually get everything, but there are some things that are pretty easy to miss in the second episode (DownFall) so please check it out! <3

During your first playthrough you won’t be able to explicitly choose which route you’ll start with, since it’ll be decided by your choices in the personality type-like quiz + a bit of luck. If you nonetheless want to start with a specific route…
You’ll need to think of it as a point system. If you get a tie (or multiple) it’ll probably assign you a random route.

• Q1:
  
  • Make it yourself +Keito
  • Keep praying for it +Ryou
• Character you bump into (random):
  
  • Student A +Ryou
  • Student B +Minato
  • Man +Haruki
• Q2:
  
  • Shared it with others +Minato
  • Kept it to ourselves +Haruki
• Q3 (I’m pretty sure this one doesn’t add to anyone):
  
  • I wanted the world to end
  • I didn’t want the world to end
• Observing each character:
  
  • I am curious +that character’s route

Starting your second playthrough (btw, you’ll need to press Restart, don’t be afraid) you’ll be facing some choices to unlock each character’s route, as following (also think of it as a point system):

• Character you bump into (random):
  
  • Student A +Ryou
  • Student B +Minato
  • Man +Haruki
• Take a seat:
  
  • …on the right +Ryou
  • …on the left +Minato
  • …deeper in +Haruki
  • …close to the exit +Keito
• Observing each character:
  
  • I am curious +that character’s route

This time, you can unlock multiple routes at the same time (or none at all!) and you’ll see it in this selection screen:

• …dark-skinned youth [Ryou’s route]
• …black-haired student [Minato’s route]
• Sit in a seat deeper in [Haruki’s route]
• Go outside [Keito’s route]

You can notice there was a red choice in the last image. Follow the two red choices to unlock the Outro. Choosing “Call out to someone, after all” will assign you a route instead.
Finish reading it to unlock the second episode +CGs +FallDown achievement

Tip: You’ll get the best experience if you read the Outro after the four character routes

Is there a recommended reading order?

The game presents the routes as: Ryou, Minato, Haruki, Keito; both in the prologue choices (where to sit) and in multiple sections of the menu. I’ll be following that during this section. However, there isn’t a correct or incorrect way to read them.
Though, if you want to have the best experience, leave Keito’s last if you can!

During this episode, the most you could miss are CGs so I’ll mark those. I’ll add a * if there’s a choice that presents additional interesting details about the characters/world. Otherwise, you’re be free to go blind with them. Have fun!

• Ignore him * -> only first “Ignore him” choice, the second one doesn’t give extra details
• Get on the black horse +CG

Proceed as you want with the rest +I Won’t Run achievement

• Eat with him *
• Then you try it! *

Proceed as you want with the rest +Spell of Midnight achievement

• I don’t do that kinda stuff * / Do you fancy me or something? * ->I suggest saving and loading to see both paths. Hint: You’ll be good to load the choice selection again when you see “party” in the dialogues.

Proceed as you want with the rest +Loveless achievement

• It’s fun * / It’s a bit lonely * -> Same as before, I really suggest reading both paths. You’ll be good to load the other choice when you see them talking about a children’s book.

Proceed as you want with the rest +The Boy Who Wouldn’t Grow Up achievement

No matter what choices you pick, you’ll eventually get to the same ending for each of the character’s routes in FallDown. That means, as long as you read them all, the achievements and their endings are unavoidable!

Welcome to the second episode! If you got here by chance without finishing all FallDown routes, please go back to them.
As you can see when you open DownFall, there are 9 chapters and some “Tips”. I assure you, those Tips are important. I’ll do my best to guide you through them.

These chapters have little to no choices and are pretty straightforward, but you can get some achievements:

• Yes +Songbird achievement

• Please remember… looks +All About the Looks achievement

You can read Tips 1 after this chapter

• Hurry up +unlocks Chapter 4
• Take a detour +unlocks Tips 3
  

  It is important to read all Tips before Chapter 4, so you need to pick the “Take a detour” option during your first read

In the Legacy version (i.e. before DoomsDayDreams release), the order was:

1. Chapter 1
2. Chapter 2
3. Tips 1
4. Chapter 3
5. Tips 2
6. Tips 3
7. Tips 4
8. Chapter 4
9. …and so on

(That’s why I mentioned you can read Tips 1 after Chapter 2)

However, you can read both Tips 1 & 2 whenever you like as long as it’s after Chapter 2 and before Chapter 4!
Tips 3 is on the same boat, and you’ll need to read it to unlock Tips 4: the character routes.

Similar to FallDown, there isn’t much of a recommended reading order other than leaving Keito’s route until the end.
But, this time, there is an optimal path for the routes, where you’ll get all important story scenes + CGs + achievements. This path follows the Legacy version.

• Treat him myself
• …an older brother…
• I don’t
• A future

+Connections achievement

• Stop him
• …approval
• I’ll fight, too
• …no form

+Morning in the City achievement

• …know you
• Take it
• Don’t say something so cruel
• I will live…

+A Final Smoke achievement

(See for yourself!)

+The Little White Bird achievement

There’s an special achievement you can get during three of these four routes at the red choices scene:

• Ryou: I don’t -> A longing
• Minato: I won’t let him fight -> …his source of comfort
• Haruki: Don’t say something so cruel -> …is wrong

+Rejection achievement

After reading through the main 4 routes, don’t forget you can return to Chapter 3 and pick “Hurry up” to unlock Chapter 4!

Reminder: before Chapter 4 you should have already read all Tips.

In this chapter you will get to another route selection screen, this time with the characters you met during the Tips:

Who do I pick first?

You may pick whomever you like the most, go left to right, right to left, it doesn’t matter! Some recommend leaving Samejima’s last but it isn’t as necessary.

Selecting one of them will start Chapter 5.

No side route in Chapter 5 has any choices, however, they do share some common scenes. You can notice it since when you start the chapter you’ll see the first image, but halfways the second one will appear. That’s the “common” section, which the game calls “Dissonance”:
Dissonance starts ^

After finishing Dissonance, you’ll return to your respective Side Route. You’ll know cause whomever you picked in Chapter 4 will start a flashback.
Finishing Chapter 5 will get you the following achievements, depending on the route you read:

• Touma +Clair de Lune achievement
• Arisugawa +Goodnight Moon achievement
• Ni’igaki +Unfulfilled Mayuri achievement
• Samejima +Crabapples achievement

You have two options:

1. Keep reading until the end of Chapter 9 and return afterwards
2. Read all Chapter 5 routes before reaching DownFall’s ending

Here’s where it’ll get tricky. You need to know there are some scenes in Chapter 7 & 8 that directly relate to the route you last picked in Chapter 4-5. The longer and most important ones are in Chapter 7. They are not important to understand DownFall’s ending, but are indispensable to comprehend DoomsDayDreams content.

What is my recommendation?
Whichever option you picked before (read until the end or before reaching the end) will lead you to lots of skipping read text. Just be sure to read Chapter 7 & 8 after you read each one of the pink house routes!

Though, if you must have the absolute best experience…
You can read all four routes before even starting Chapter 6. Go in whichever order you like! Then read as normal until you finish DownFall.
Remember when I said those scenes relate to the route you last picked? That’s right, you do not need to read all the routes again, just select the pink house character (can be done hovering over the Chapter 5 button), return to title, go to Chapter 7 and skip through it & Chapter 8. Repeat for each character and enjoy!

Finishing at least one Chapter 5 route will give +Pink House achievement

Let’s return to easier things. This chapter only has a set of options:

• Take the hand +Absolution achievement
• Don’t take the hand +Continue Chapter 6

No options. Check Chapter 5 for more info.

+True Course achievement
Be sure to read the credits as well!
Continue until you get the +DoomsDayDreams achievement

DoomsDayDreams is the conclusion of MAMIYA’s story, it has 16 endings, lots of CGs, and some interesting achievements. Reaching all endings should unlock most of them, so the focus will be on that.
If this episode isn’t unlocking it might be for the following reasons:

• You didn’t read DownFall’s ending until the very end
• You haven’t bought the DLC yet
• You have bought the DLC but it isn’t installed yet
• I think you need to be online after you first install it but I’m not sure about this one. Might be worth a try

There is a “scent” option here that’ll present you with some details about certain characters. I recommend you reading both if you’re interested. Does not lead to CG or achievement nor affects the story in any way.

• 2003
• no MAMIYA / not a year (any option is fine)
• failed to stop the pink house members

If you get 1 & 3 wrong three times +Permanent Overtime achievement

Finishing the prologue will lead you to the route selection screen:

As you can see, it’s divided into two sides: DayDreams (Keito and Ryou) and DoomsDay (Minato and Haruki)

Is there a recommended reading order?

This time, there is. Even if it isn’t mandatory, reading in the following order will make the story flow better:

1. Ryou
2. Keito
3. Minato
4. Haruki

The first choice in this chapter will only lead to a minor branch path.

• Not what I want +Continue the story
• … +Que sommes-nous achievement (Ending 6)

• … at sea
• … in 1999
• Suou Keito
• In 1999

Following those choices will continue the story. Failing them will give +Blissful Souls achievement (Ending 5) (it is impossible to fail the first one afaik, try from the second one on). This is a shared ending/achievement.

• …will be heard +Continue the story
• …will not come true +You Can Fly achievement (Ending 14). This is a shared ending/achievement

• Reconsider +LAST DINOSAUR achievement (Ending 8, Ryou’s good ending)
• Punish +Spring of Aging achievement (Ending 7)

Easter egg: why don’t you load this Chapter 7 again from the selection screen?

All choices happen during Chapter 6.

• … at sea
• … in 1999
• Suou Keito
• In 1999

Following those choices will continue the story. Failing them will give +Blissful Souls achievement (Ending 5) (it is impossible to fail the first one afaik, try from the second one on). This is a shared ending/achievement.

• …will be heard +Continue the story
• …will not come true +You Can Fly achievement (Ending 14). This is a shared ending/achievement

• Believe in them +Continue the story
• I lack the confidence +Family achievement (Ending 15)

• I can’t bear it anymore +Author achievement (Ending 13)
• Continue to bear it still +Thus I Dream in the Future Too achievement (Ending 16, Keito’s good ending)

Unlocks after getting at least one ending of each route.

• Swear loyalty +Les Fleurs du mal achievement (Ending 3)
• Don’t give up… +Continue the story

• Perhaps we are +The One Who Once Was Venus achievement (Ending 2)
• I’m not like you +Continue the story

• Ni’igaki Mayuri +The True Form of Anger achievement (Ending 1)
• Morichika Haruki +” ” achievement (Ending 4, Minato’s good ending)

• Try to listen… +Continue the story
• Suggest a way… +The Price of Snowfall achievement (Ending 11)

• Ask… for help +Burned Black achievement (Ending 10)
• Endure it by myself +Continue the story

• Introduce myself as… +Lessness, Less achievement (Ending 1)
• See how things play out +Take Me Home, Country Roads achievement (Ending 12, Haruki’s good ending)

Unlocks after getting at least one ending of each route.

You’ll unlock this section after reading through all previous routes and Another Tracks.
Go blind and follow your heart. Enjoy!
(Choices don’t matter, you’ll eventually get all CGs if you keep reading)

From the title screen you’ll eventually see an “Extra” button. Here you’ll be able to read What-if scenarios and unlock EX.

To unlock extra scenarios you’ll need to search for what-if pages. It is a gacha and you can only search for 5 of them each day. Each computer day (wink).

There are no choices in the what-ifs, however, the scenarios number 8, 14, 15, and 16 have CGs

Reading all what-if scenarios will give +Just One More Story achievement

After reaching DoomsDayDreams’ True Final Ending, return to the Extra section in the game. You’ll notice some details.
When you leave, you’ll get the option to unlock it:

• Pick up the page +Last Ember achievement

If you want to access this new content, go to restart and you’ll see that small arrow on the side.

EX has 6 CGs and a single set of options. If you reached this point I’m sure you’ll try them all. I do recommend leaving the bottom one for last, though.

If you did everything right and you read all there was of MAMIYA, you’ll get +Seeker of Beautiful Things & MAMIYA achievements. Congratulations!

Thank you so much for reading this guide, I hope it was helpful enough! I did binge doing it in a single day so please tell me if you find a mistake.

I welcome all comments and questions!
