I divided the Achievement Guide's guidance into three levels.

Hint: Indicates the information that is disclosed directly. Suitable for players with rich experience in choosing oriented games, who only require a little bit to understand where to start the achievement immediately.

Guidance: More obvious prompt information may be a person's name or task. It suits players who do not want to receive too much information about the story.
Reminder: if you can get clues from the first tip, you do not have to see the second and third tips.

Instruction: Almost hands-on guidance, mentioning every important node and the position of options that I think might be wrong. For new players who are new to choice-based games or players who have been stuck on a certain line for a long time.

I made three guidance levels because the Mask of the Rose did a great job integrating information and connecting different characters' quests. As a visual novel game, the pleasure of playing comes from the story. The excitement comes from digging for pearls (knowing and understanding the characters) and connecting pearls (feeling the connections between the characters' quests and main lines).

I don't want to ruin the experience, so my guide contains a lot of black boxes (trying not to give away the plot, not mention the specific plot, and not diminish the enjoyment of the game). And I hope every player can enjoy the process of exploring stories.

In addition, I want to encourage the struggling early players and the mid-level players who are trying to find a way to their achievements. All of your efforts to explore the story are worth it!
Every ending in this game is worth trying, among which the real culprit ending is excellent, referring to a lot of foreshadowing about a certain character. Of all the visual novels I've played, it's really impressive.

You will easily get these five achievements once you finish the game.

The first two achievements help the player establish character awareness, make initial contact with character relationships, and unlock possible character quests.

Confessor → Understand the favorability mechanics of the game
Censurious → know almost all the characters

Important advice :
When meeting people except for Mr Page, it is best to wear the flower brooch( the badge could not help build the relationship).
When you meet Mr Page, of course, it is best to wear the badge to improve the relationship between you two.
You can consider selecting friendly options and special options provided by brooches, which can increase the characters' liking for you quickly and unlock their quests faster (see what you can do for...). Also, high favorability with the character enables you to ask for more things in a single inquiry for your case.

Censusious achievement is best to be done during early rounds because it helps you quickly build character awareness, expose them to possible personal quests, and thus speed up the investigation since you already know various characters and can predict what help you could obtain from them.

Reminder: if you can get clues from the first tip, you do not have to see the second and third tips.


Hint: There is a message in the game that mentions a person responsible for Halloween decorations. It is also a person that you can get clues about the case from.

Guidance: 1. Ivy, 2. trigger with high favorability , 3. question her after you build the case story in the second week

Instruction: Meet Ivy within the first week. You can open the location by doing Horatia's census or letting Harjit lead the way. During the Horatia's census talk, you need to achieve high favorability with her in order to unlock her quest. She will ask you to go to the market to bring something for her, which will unlock the spot for the player.
When you first meet Ivy (for example, to finish the census), wear the flower brooch instead of the badge, choose friendly options, trigger the relationship selection mechanism, and choose to be friends. At the end of the conversation will trigger the relationship mechanism again and choose to offer friendship.
The second week of the investigation begins, make the case story . You can leave the motives blank to trigger questions about xx's motive. Then go to her to ask questions and pay 2 pounds or use friendship to get her to talk. At the end of the conversation, it triggers a confession event.

Update: According to finalCalzone's comment, if you chose to unlock the spot where Ivy is through Horatia, it may be better to finish her census before the arrest. After the arrest, some quests will be more difficult to trigger.


It can be done together with the next achievement: Suited and Booted.

Hint: 1. Some characters' quests can lead to new locations and new characters. 2. It is best to open the location the first week to meet most people and make the censuses (to save time). The census option may not pop up when some characters are newly acquainted after the investigation case begins in the second week.

Guidance: New location cave leads to 2 characters. Help the priest leads to 1 character. 1 new character will join your house in the second week. The new spot unlocked by helping Harita or Milton leads to 2 characters.

Instruction: 2 demons, 3 family members +1 stone man who joined later, 3 in Landaus house, 1 patrol officer, 2 merchants, 2 former city survivors in caves, 1 priest +1 Reginald who you can make the census after helping the priest to get him back.
Priest: Meet a priest with the flower brooch and select the friendly option. Then open the page and click 'see what you can do for...'. If the option does not appear by clicking on location of the church on the page, it indicates that the favorability is not enough.

A small tip: Check the expressions on the character when you two first meet. If they smile less, your favorability with them improves too slowly due to your choices.
You can consider returning to the main page before you two finish the conversation and read the file to start again.


Hint: "Buy", "buy" every hat and torso item. All censuses give you enough money to buy all the hats and tops, and you can even remain a bit.

Guidance: Purchase everything in Ivy's and Ferret's stores, including hats, wigs, and torso items.

The ending achievements could be split into 4 lines .

The first line is to get help from higher-level persons, including 2 end achievements and 1 hidden achievement you can get during the process.
Intervention: The Last Bill, Hell Hath Such Fury, Abstracted

The second line is to break the jail, which includes 1 end achievement and 1 hidden achievement.
Jailbreak: Sanctuary, Baptism


The third line is to find the murderer, which includes 3 end achievements.
Murderer: Acceptance, The Impostor Synod, Ascension

The fourth line is 1 special end achievement. It is also linked to the case, but it is in a completely different direction compared to finding the true murder line. So, I take it out separately.
Special line: Reunion

Note: The ending line achievements can only be unlocked after the Rose Festival and reading the characters' epilogue.

A small tip: do not wear the department badge to see people. Best wear the flower brooch to meet for the first time. It is best to choose "The census is my own idea. " which increases favorability with them more, along with special options provided by the flower brooch.
It is totally fine if you don't wear it. But if you do, it will make some characters like you less when you first meet.

Hint: Keyword express: 'Bill'. A character's quest. You are familiar with this guy.

Guidance: It belongs to the intervention line of three lines (finding the real murderer, getting the intervention, and breaking out of prison). Maintain a good connection with Griz and take his personal quest.

Instruction: Choose the friendly option whenever you meet.
Tip: Choose the joke option. Do not exclude her when Archie wants to talk. Thank her after meeting Mr Pages for the first time. Wear the flower brooch and make her census. Respond kindly when she talks about her background. She will mention her quest to you. If she doesn't, choose 'see what you can do for...' to trigger her quest. She will ask you to lead her way to the parliament location. Lead the way for her and finish every quest she asks.

Open the parliamentary location method:
The first method: help Mr Pages complete 7 censuses, be friendly with him and do not doubt when you get answers from him each time at the end of the meeting. After you submit 7 censuses, there will be a relationship selection mechanism, choose to be a friend/lover, etc. He will take you to see the parliamentary site.
The second method: After getting Griz's mission, let Harjit lead the way. It will cost 4 pounds.

Note: It's best to meet Theophilus the first week, take the census and improve your favorability (choose friendly options).


Hint: Hell, one character's quest

Guidance: Help Virginia, another branch of the intervention line.

Instructions: 1. Wear the flower brooch when meeting demons for the first time. Always choose the friendly option and the special option provided by the brooch. Wait until the end of your first meeting with Mr Pages, choose to ask the question on the map (saving time), and then open the location page and select "See what you can do for Virginia" to open the character quest.
Process: Answer the map – make her story -- get permission from her -- meet Mr Pages – ask for her intervention
2. For the story, focus on portraying Virginia as a strong leader of the resistance. If you are interested in the truth, obtain Milton's opinion and submit the story in Milton's presence (Virginia will reveal more information).
3. After Virginia successfully gets the ambassador position, a new option appears on the location of the House of the Devil on the map: ask her to intervene. If you had already helped Virginia on the day he was arrested, the option immediately came up at the end of the day: Maybe Virginia could help. Click and then finish the Virginia line)
4. After asking for permission, she will give the new exclusive tools of hell to commit crimes. Make yourself the murderer when forming the case. The method is what she provides, the hell poison. The motivator can be David. Then submit the case to Harjit. Virginia will appear in court.

"You can communicate with demons, make friends with demons, and even experience intercourse with demons." But doing business with the devil? Some kind of private business with a huge price? Well, you'd better not think about it at all."
"The price is not something you can afford."

Hidden achievement # 1:


Hint: The name and the sentence are explicit.

Guidance: 1, Soul , 2. Hell

Instruction: Unlock it with the hell achievement. In the Hell intervention ending line, after asking Virginia for help, when Virginia asks you to pay the price, choose to pay your soul,

Update: According to Piggy in the comment, Virginia may not ask for a price if the player have helped her get the position she wants.
If it happens, maybe you can try finish this achievement in the line of 'The Impostor Synod' achievement. Virginia will also ask for a price, where you can choose to submit your soul. I remember it is during the time you help the priest retrieve the treaty of his soul.

Be careful. According to 0bsidianFire's comment, if you submit your soul , you won't be able to flirt or seduce other characters.

Hint: "a profusion of small friends", one character's quest

Guidance: Ferret. Keep a high favorability with him, trigger his talk about his small friend, and then finish his quest. It is the Jailbreak line among the three lines.
(don't forget to select the jailbreak option)

Instruction: 1. In the first week, meet Ferret, make his census, and choose friendly options. If he smiled more, select "No gender question", then "Actually, I don't care much about this question either" (if he looked unhappy, try other options). Finally, the relationship selection mechanism appears. Choose to be friends (choosing not to be his friend is also okay). The relationship selection mechanism can help check whether you obtain enough favorability with the character.
2. The next day, choose "See what you can do for him", and he will introduce you to his mouse friend, be kind to the mouse, and then make up the mouse's story. If the story is put together correctly, a sentence will pop up on the story page. There will be an exclamation point at the church, and then give it to the priest (choose the option that can help the mouse).
3. Then, start piecing together another story. Go to the location of Mr Pages, select the library to explore information, focus on the mouse, and unlock characters, the saint and a series of options you fill the story. Spell the story: Left saint, right mouse king, piece together successful points to propose a bullet conclusion, and then see the priest ready to give the mouse baptism.

Small tips: 1. Whether you trigger the relationship selection mechanism or not can be used as a tool to check the character's favorability for you. If it is high, choices to be friends, lovers, etc., will pop up.
2. If the story is pieced together in the direction you can obtain some conclusion, hover over "Submit", and you will see that the option is not lit. And when you try to click, it props up a conclusion. If the piece is not put together towards the direction you can obtain something, hover over the "submit", and it will have a bright edge that enables you to click. No conclusion will pop up.

Hidden achievement # 2:


Hint: A small branch choice of the jailbreak line

Guidance: Change the direction of the second story

Instruction: The previous processes are the same as the sanctuary achievements. The changing option is on the second story. Put the mouse king left and a mouse right, and do not involve the saint. Submit the report to Ferret, and then during mouse baptism, choose to join the baptism.

Note : If you can choose not to check the guidance and instructions, then do not look at them. Try your best to find the murderer based on your understanding of the characters and the relationships between characters.
The reason is that the pleasure obtained after clearing the clues of the case can only be obtained by your own exploration.
If you read the instruction part I gave you, your experience of the game will be significantly reduced. Because all the instructions I gave are just shortcuts.

If you feel that the investigation is very difficult, I suggest that you finish the above achievements, explore the quests of each character, build your impression of the characters and become familiar with the character relationships. When you complete these and start the case investigation, you will find the case becomes much easier.

The investigation of this game is based on your understanding of characters and relationships between different characters . If you are not familiar with these two things, it is normal that you cannot find the real murderer easily. Just relax and take your time.


Hint: The achievement statement clearly states that it is the line of finding the culprit.

Guidance: 1. Sources: Ferret, David, Phoebe, 2. Pieces together the case to pop up questions about motive and questions about the method

Instructions: 1. Complete the censuses of David's family in the first week, as well as Phoebe's census and Ferrit's census. It is preferable to maintain a high favorability with them (it enables you to ask more questions about the case during one conversation later).
2. At the beginning of the second week, you can start to piece together the case, randomly select all the blanks on both sides and select the unknown method at the top to pop up "Questions about the method of the crime". A new exclamation mark will appear at the Ferret's store on the map, click the new option, and meet to talk about the problem of arsenic.
3. Then meet with David, and if you maintain a high favorability rating, ask all the questions at once, and choose all the questions.
4. Piece together the case again. The method is the arsenic candle, the left is Phoebe, and the right is David. Fill in every blank part and click submit.
5. Then, the location of David's house appears with new options for you to ask. First, Meet David to talk about Phoebe's motive. Then click on another new option about Phoebe, 'accuse her', and Phoebe will confess something.
6. And then, finally, update the story (the candle, Phoebe" s motive(love), and behaviour (treat David)). The motivator person is David. Hand over the case to Harjit.

As for why the name is accepted: It is a half-true ending, and someone is still hiding.


Hint: The previous processes are the same as the last achievements. However, there is a small quest that needs to be completed.

Note: follows the same line as the previous achievement above. When you choose the condemning / confronting Phoebe choice, Phoebe asks you to do a favour. Promise to help and get her a priest. Finish Theophilus's mission.
Update: Retrieving the soul is enough to unlock the achievement according to Storminka's comment.

Guidance: After agreeing to help Phoebe, go to the priest and pay attention to the choice of questioning when communicating. You need to force out the priest's confession on his problem.
Then negotiate with devils. You can choose your closet as the price.
Update: Retrieving the soul is enough to unlock the achievement according to Storminka's comment. So, you can just hand over the case to Harjit.
Return to see the priest, and then go to the devils to ask them to return the treaty. Pay four or five pounds, return to see the priest, and finish his quest. Then, hand over the case to Harjit.

Once again, the name of the achievement is a reminder. The real murderer is someone else.


Hint: 'ascension', 'enters the hereafter' The hidden quest of one character. Think about which character is often involved in the story, but their own quest seems to be a little short. Also, think about a clue about the case that you obtain in the early process of the case.

On the other hand, it depends on how well you know that character. If you've been a friend or a lover of that character and you've heard that conversation, you might be able to realize who the character is.

Guidance: 1. A demon. Virginia's request is already linked to one achievement, so naturally, the one left is... 2. Think about what clue you get when you dig up the body. When later questioned one person, this person will answer, "He/She saw someone doing something." There will be part of the sentence that coincides with that clue. It provides a new optional option when you piece together the case 3. Ivy, asking about the motive of an unlikely person

Instruction: 1. See Milton in the early stage, maintain high favorability, and click to see what you can help. Ask Harjit to lead the way and unlock the underground cave to meet two new characters.
(If you are unfamiliar with their quests, do not finish the task they give you.)
(There are branches in their quest, and if you fail to gain enough favorability from one of them, they will split up, and you will have to find one of them, which will take you some time)
2. When digging up the body, keep looking at the body until the sigil clue is found. The process in the first stage of the investigation is the same as the last achievements (Ferret, David). Piece together the story, pop up the questioning means, question the motive, and click Ferret to get the arsenic candle clue.
3. Click on Ivy to pay 2 pounds or utilize your friendship. Listen to her talk. Piece together the case again, leave the motive of the culprit blank and choose the culprit to be a maybe impossible person, such as Archie. Then ask Ivy about the motive, and she will mention that she saw Milton doing something with the sigil.
4, Piece together the story. The left is Phoebe, and the right is Milton. Complete the story. Then the House of Demons presents a new option: challenge Milton.
Note: It must be the "challenge" option, which proves that your story is pieced together in the right direction. The other options like "interrogate" or "confront" are not what you have to click. If the challenge option hasn't come out, it's probable that you're still short of clues. You can continue to ask David and Phoebe about the case.
5. Milton will tell the truth but asks you to help him investigate his last death. He'll put a few exclamation marks on the map, don't bother to check all of them. Go straight to the cave to see the Barqujin, ask about Milton, give the information back to Milton, go to the cave with Milton, and go through the process. Finish Milton's mission. Then give Harjit the case and listen to the truth about the case in court.

Well, somebody finally gets what they want.
What is interesting about this end is that this is a win-win end, which is rarely to be seen in case story. The writer did an excellent job on this end.

This achievement has nothing to do with any route a very special ending. The whole process, from the start of the investigation to the final trial, differs from the culprit line and any other lines.
It inherits some of the mysterious atmospheres of the previous games, such as the Sunless Sea.


Hint: The entry point is challenging to think of, and you must identify an unlikely person as the culprit.

Guidance: 1. Related to Archie and May , 2. need to complete two small quests for Harjit , 3. Recall the past to find Lucian, 4. Identify Archie as the culprit

Instructions: 1. Start with a criminal background (other backgrounds can also achieve the achievement, some special options from this background can drop the favorability quickly), choose unfriendly options with Archie
2. Wear the flower brooch to see Harjit, click the choice to wear the hat, click on the special thank you option provided by the flower brooch, present the census question as your own, ask if there is any change about the information, promise not to tell anyone, listen to his story, click on the special option about wiping tears (or offer solidarity), mention the person may still be found, trigger Lucian photo event, click on you recognize it.
If it is not triggered, the favorability is not high enough. You can choose to reread the file or ask him to lead ways several times. During each conversation, be friendly and compliment him.
3. Go back to the house, click to recall the past, and choose the recall Lucian choice. If it does not appear, choose one choice randomly and recall the memory the next day (the first choice will be about Lucian). Then choose to see if there is anything you can do for Harjit. To preserve the memory for Harjit, you can ask Mr Pages or Milton for help, then tell Harjit about what you found. Also, submit your memory of Lucian to Harjit. As you reminisce, you can also recall your memories of Archie.
4. After Archie is caught, if the likability is low enough + criminal background, the third option is 'Archie has a high probability of being guilty', choose the last one. The page will open up new exclamation points about Archie, such as Finding evidence of Archie's guilt. The day David woke, the Journal would open a new quest, 'Archie may not be himself.'
5. Piece together the story. Archie's motive is that he may not be himself, wait for the moss to appear, treat moss kindly to open its quest, choose 'see what you can do for Moss' on the page and follow his quest. Find Harjit to help find someone.
6. When you find May, there will be a new option about Archie. Choose it.
If the choice does not jump out, read the file. It possibly means that the choice you chose is not firm enough to lock Archie as the culprit.
May gives new clues. Update the story. Archie's motive is he may be dreaming. Submit the case to Harjit and enjoy the trial.
Update: It is okay if you do not update the clue.

Hell Hath Such Fury:

The worst of all the ending branches, the masters have problems, but letting demons live in the City of London is more terrible. In this line, the protagonist is used from the moment the deal is negotiated to the end, Virginia obtains the master’s permission with the protagonist’s help to build political forces, and then relies on the case trial of the protagonist using the tools of hell to commit crimes, opening the time that hell interferes with the legal judgment in London.

The past hell can only be said to be separated from the human settlement of London, and this first interference in legal judgment will sound the horn of hell in London's legal and political sphere. As the ending shows, Virginia has risen quickly to the pinnacle of power in a short period, making the devil a guest possibly a new master in London. And the main character who starts as a guest of Virginia and Milton for their consideration of information, then quickly becomes a slave who spends his life working in the basement.

The ‘fury’ of the ending title refers to the unprecedented speed with which the evil envoys in London, led by the ambitious Virginia, ascended to the stage of power in London, and quickly swallowed up the power of the Masters, becoming the de facto rulers of the populated city.

Ascension:

This is the line that I think most demonstrates the high level of the writer’s script, From the other ending to the murderer’s ending, from the semi-murderer’s ending to the real murderer’s ending, the player will step by step to the heart of the case, and finally in this line to connect the clues that the semi-murderer did not connect.

From the very beginning, it is difficult to forget the sigil problem when digging up the body, the anxiety feeling that there are too many characters who have no way to start when touching the case, the bewildering feeling that there are too many characters who do not know which one to fight first, the surprise after finishing other endings and the difficulty of sitting and standing still knowing that they have not discovered the truth, the feeling of missing something when finishing the semi-true ending.
All these feelings are in this ending line to get the end. All the cases we learned along the way were finally solved on this line.

But I think the most powerful thing about this killer ending is that it takes the foreshadowing -- the reference – this aspect of the game to the extreme. This is particularly evident in the creation of Milton’s character image. If you had been friends or lovers with Milton, everything you learned about him in the course of your communication would be wrapped up in this ending line.

About death, he would personally say that his last death was painful: "I died, but it was not the death I chose." I’m not ready to return. When I returned to the world, I found only remnants of the past. A saddle that was once mine, a long song translated into the words of hell. With some effort, I finally retrieved my old name. It doesn’t belong to me anymore, but I keep it, as a souvenir."

About names, when he mentions his name, he brings up the few memories he has of the past, and he also mentions the real body. And if the Rose Festival had chosen not to meet Milton but to meet him briefly in the process, Milton would have mentioned it himself.

"I died in the Fourth City, and it was a wrong death. To die again and finally get back everything I’ve lost... Who knows, maybe one day I can remerge like Virginia." [/i]

After the end of the real product, the dialogue of who knows (who knows) is very charming, yes, how could he want to think that he really can get a chance to remerge. The front saddle and the long song are also pointed out in the true ending line.

At the same time, his personal mission to help him meet the survivors of the Fourth City will open a new option. Barqujin will reply: "It seems that the Khans may still be alive, or the enemies of Yellow Eyes are still alive." All it took was one sentence to point out that the two might have crossed paths.

It can be said that this line proves the excellent skills of the production team’s character creation direction, about his foreshadowing has long been buried, his hidden line is both unexpected and reasonable. His hidden side is not based on building new hidden surfaces, but on integrating and processing the information he reveals, so that his hidden lines are not very confusing, but can still surprise players who have spent time with him before.

I wish every player who has entered this game can achieve full success as soon as possible and experience these excellent ending lines of this game!




Except these interesting ending lines, I wish every player had a great time building your relationship with characters! I mean, they are all so adorable!
