Salutations!
After a whole bunch of run throughs, I've finally got enough information to compile into a guide that I hope will be of use to others!

Before you use the guide please keep in mind that I have only included options needed for endings concerning the character in question, rather than every option I personally chose. This is why there are a significant amount of options missing from each of the characters' sections.

Thus, if a choice appears that isn't listed in their section of the guide AND the choices do not concern the trainers (such as during training sessions), you are able to choose whichever option you wish as it won't affect if you get the desired ending or not.

Other options concerning the trainers and a few key moments in the routes have effects on the war aftermath but do not change the direction of the good/bad endings. Thus, they get their own sections near the bottom.

I’ve tried to keep the spoilers to a minimum but the titles of the endings are given in these posts. (Minus the letter for the Angel’s Password.) The Angel's Password is covered at the bottom of the guide.

If you have comments, suggestions, revisions to be made, or new information, please let me know!

DISCLAIMER: This is an unofficial guide! All information in this guide is based on the following observations and the spamming of the 'Skip' button. (As well as the consumption of a saplings' worth of paper.)

• Endings are based more on the total amount of right choices than the choices themselves.
  In that sense, some choices don’t affect the endings at all while others might be a tipping point between getting the good end or the bad end.
  
• Choosing alternative options along the way changed the ending result despite the point total.
  For example, while aiming for the “Hopelessly Devoted to You” ending a second time, I chose “Let Erik keep going.” option when trying to remove the Spirit. Later I received the “You Hurt Me, Now I’ll Hurt You” ending despite having selected all the “correct” answers, so I can only guess that this means some options can actually remove points instead of being neutral. (Or otherwise are, as stated above, a tipping point.)
  
• Some choices seem to only affect what dialogue is shown rather than the full storyline.
  For example, in Sam’s route, if I bring up the Demon Wedding during the planning the day after (When you’re alone with Sam) later in the game when you’re deciding between “Kiss him again.” and “Nuzzle into his shoulder.” a small section of dialogue popped up afterwards that wasn’t seen before. At least, in the run-throughs I did prior to this. It didn’t seem to affect the story at all but it’s interesting to note. I wonder how many other options could lead to some extra (or less) dialog?

Erik’s route is pretty straightforward. I found that no matter the interactions with the spirit, it didn’t affect the route provided I made the right choices concerning Erik. This might be a wrong assumption, but for now I’ve left out spirit interaction. (So choose as you see fit when it concerns the spirit)

The rule of thumb: Be open, loving, and patient with Erik. Comfort him when he’s worried or feeling insecure.

• Tell Him
  
• Kiss Him
  
• Hug Erik’s arm tightly.
  
• I was never disgusted by you.
  
• Kiss his cheek.
  
• Cuddle with him.
  
• Kiss me. / Hug me. / Pull him to you. [Any option will increase points.]
  
• Comfort him.

• Don’t take any chances! (When you see the Demon Lord in your room.)
  
• Let Erik keep going. (When confronting the spirit.)

• If I Can’t Live, You Can’t Either
  Get four (4) or fewer correct choices.
  This ending occurs in the middle of the game and you will not reach the end of the war.
  
  
• You Hurt Me, Now I’ll Hurt You
  Get between five (5) or six (6) correct choices.
  This ending occurs during the battle with the Demon Lord and you will not reach the end of the war.
  
  
• Hopelessly Devoted to You
  Get at least seven (7) correct choices.
  This ending occurs in the aftermath of the demon war. You will reach the end of the Demon War (And other decisions made may affect the aftermath but will not affect you reaching this ending.)

It should be noted that for Sam’s route, you will need to allow Sam to enter the cave AND pass the test to be able to reach the good end. I recommend saving early on so you can access

The rule of thumb: Be patient with Sam and comfort him when he needs it.

• Small wedding.
  
• Kiss him.
  
• Help me stay awake.
  
• Kiss him again.
  
• Wait patiently.
  
• Tell Sam the truth.
  
• It’s okay, Sam.
  
• Stop him.
  
• Kiss him.
  
• Boy, you are going to let me kiss you.

None for this route.

• Hand of the Devil
  For this ending, the amount of correct options doesn’t matter so long as you make it to the final battle to meet Malix. The most straightforward way to do this is to not allow Sam to take the test, rendering your choices null. When prompted, choose to help Sam in the fight. (“Help him!”)
  
  
• You Are Not Worthy
  For this ending, allow Sam to go into the cave. (”Let him do it.“) If the amount of correct answers in previous decisions is eight (8) or less, you will reach this ending.
  
  
• The Monster is Dead
  To reach this ending, do not allow Sam to go into the cave to take the test. By doing so, you lock on to this route. (Provided you let Sam fight on his own against Malix.)
  
  
• Hopelessly Devoted to You
  
• To reach this ending, you will have to have allowed Sam into the cave and passed the test. From there, let Sam fight on his own against Malix and when prompted, choose to return to the Human world.
  
  
• A New Life
  To reach this ending, you will have to have allowed Sam into the cave and passed the test. From there, let Sam fight on his own against Malix and when prompted, choose to stay in the Demon world.

For Damien’s route, if you don’t go through with the ritual you will be locked on a bad ending. If you do proceed with the ritual but it doesn’t succeed, one of two different bad endings will occur depending on a final choice. If the ritual does succeed, it’s a straight shot to the good end.

The rule of thumb: Support him and his dream. Don’t be afraid to express your curiosity.

• No way! It’s cute!
  
• Give him a squeeze.
  
• What do you think about this whole thing?
  
• What about you?
  
• Stop doing anything.
  
• He wants to be a human.
  
• Take as much as you want. / A kiss, then. (Both will grant you a point but the former will grant you an M-rated scene.)
  
• Kiss his cheek again.
  
• Take me instead!!

• I’m happy he’s a demon.

• My Life For Yours
  For this route, you need to get six (6) or fewer correct answers.
  Allow Damien to go through with the ritual (”If it makes you happy, then do it.”) and during it, choose “Take me instead!!"
  
  
• Up in Flames
  For this route, you need to get seven (7) or fewer correct answers.
  Allow Damien to go through with the ritual (”If it makes you happy, then do it.”) and during it, choose “Fight this!!"
  
  
• A Demon ‘Til the Day You Die
  Protest against Damien performing the ritual (”Please don’t. It’s too risky.”) and you will be locked on this path. Choices you make will be rendered null.
  
  
• You are My Dearest Dream
  For this route, you need at least eight (8) correct answers.
  Go through with the ritual and succeed. You will be locked on this route afterwards.

For James’ route, I found it tricky to get past the Demon Lord section because the required amount of right answers from past choices was high. You can miss only one of the options.

The rule of thumb: Be truthful and loving to him. Make sure to stand your ground!

• Tell him.
  
• Tighten the hug.
  
• No.
  
• Kiss him.
  
• Kiss him before sleeping. / Hug him. (Either option works.)
  
• Bust in! (If this option is not selected, you will lose points.)
  
• I had a nightmare again.
  
• Get up and kiss him.
  
• Kiss him again.

• Stay hidden

• An Angel’s Forgiveness
  This ending doesn’t rely on correct choices.
  When confronted by the Angel after you're both taken, choose “I’M SORRY” to get this ending.
  
  
• Divine Punishment
  Get five (5) or fewer correct choices.
  When confronted by the Angel after you're both taken, choose “I LOVE HIM!” to get this ending.
  
  
• My Destiny is With You
  Get at least eight (8) correct choices.
  Make sure to choose “I LOVE HIM!” when you’re both taken. So long as you have at least eight (8) correct choices, you will get this ending.

Matthew’s route is fairly linear. I found that you need at least five answers right to get past the first bad end and at least seven to pass the next bad end, which then sets you on the good ending. This in mind, you can get only one answer wrong before you’re stuck with a bad end.

The rule of thumb: Trust in him, love him, and stick by his decisions.

• Someone's saying your name!
  
• Kiss him.
  
• Tell him.
  
• Please.
  
• Kiss him.
  
• Comfort him.
  
• Hug him.
  
• Don't apologize.

• Smack him.

• Never Trust a Monster
  Get four (4) or fewer correct choices.
  
  
• The Last One Standing
  Get between five (5) and six (6) correct choices.
  
  
• My Love for You is Endless
  Get seven (7) or more correct choices.

Diana’s route is interesting. I found the choices I made determined if I got a bad ending rather than leading to a good ending. So, in this case, the choices listed below will lead you to Diana’s bad ending.

Rule of thumb: Try to be understanding with Saero and don’t get possessive.

Choosing any choices other than what’s listed here will lead you towards the good end until you reach the choice that determines which good end you get. You will know when you're locked on the bad ending once Diana goes missing.

• Clear your throat
  
• Hug her closer -> Pull her away
  
• She loves me |OR| I love her too. -> But she's mine

These do not seem necessary to choose if you have not angered Saero but were worth noting regardless. I found that when choosing them after a few bad choices, I still got the good end, so I can assume they somehow negate previous bad choices.

• I love her too. -> But I understand your feelings for her perfectly.
  
• I love her too. -> But she is important to me.

If you’ve managed to skip over Diana’s bad ending and end up talking to Saero, you’ll be given two choices. Whichever you choose will determine what good ending you get. You are in no danger of getting a bad end at this point so choose what appeals most. (See below for the specific choice pertaining to which ending)

• Repent for your sins.
  If you decided to be possessive of Diana and rude to Saero, essentially choosing the options listed above, you will get this ending.
  
• The Right Choice
  This ending is gained if you told Saero “I want to be the one to make her happy.” when talking to him by the tree.
  
• I am Thankful for You and You
  You will get this ending if you told Saero “And I know you love her, too.” when talking to him by the tree.

You do not have to find the trainers when you first arrive at the castle. Regardless of if you’ve met them during that time, you can still get their full story. (Provided you haven’t angered them or dropped out of training.)

If you stick with them the whole week, the trek towards the castle will play out differently. Furthermore, you will end up listening in on a key conversation and how you respond can lead to an interesting aftermath and one of the four Achievements concerning them. (More about this in the War Aftermath section.)

If you lose the trainer, you will train alone and gain the "Coward" achievement.


Options that are bolded will cause you to lose the trainer. Provided you don't select these, you should be able to get through the week under their wing.

Rely on Rage: No / Yes
Danthulir: Scream!! / Jump!! / Attack!!


Spirit Animal: Lion / Wolf / Rabbit


Just leave. / Seriously?!
No / Yes
Press the question. / Yes, sir.
Leave. / Teach me something else. (You won't lose trainer as this is the last training day, but you will miss out on learning more about Shadow.)


Get out of dodge. / Stay and try


Scream / Dodge / Parry -> Scream / Dodge / Parry

Golden Rose Sub Path:

• You seem to really care for Diana.
  
• There has to be a way
  
• Are you okay?
  
• Is there any way to prove your love for her?
  
• Peer in
  
• Enter the Room
  
• You should go.

Getting Diana as a trainer:

• Stay still
  
• What about Diana
  
• Are You Okay?

Losing Diana as a trainer:
Give Up. / Struggle / Focus!

Diana’s Truth Sub Path:
Past these two, all other options don't affect seeing the sub story.

• Check it Out
  
• What was that?

For the aftermath, there are several differences you can get. What directly affects the aftermath depends on Diana's state (deceased or alive) and the trainers.


You cannot gain the trainer aftermaths if you chose Sam's path because the fourth condition will never be met. The same is true for Diana's route, since you had no need for a weeks' worth of training.

The trainer-based aftermath will depend on four conditions as well as defeating the Demon King on whichever route you've chosen.

• Which trainer you chose initially, as they will be the one to rule the kingdom provided the other three conditions are met.
  
• If you managed to keep the trainer throughout the week. If you lost them as a trainer (either by angering them or backing out) then you cannot reach these endings on your current playthrough.
  
• What you've said upon overhearing the trainer's private conversation. When prompted, you will have to tell them "I believe in you all." to gain a heavy responsibility. If you chose "I believe in Diana." you will miss the chance.
  
• If Diana survives the final battle or not. You can find out more specifics on what hazards await her in the section below.

If you have met these conditions, during the victory celebration, you will spot Diana and be offered two choices, "Stay put." and "Follow her.". Choose to follow her and after a bit of chatter, you will be given the decision to go through with your mission or not. Select "Yes" and the deed will be done.

To summarize, choose the trainer you want to lead the kingdom. Make sure to keep them as a trainer throughout the week and when asked, tell them "I believe in you all." Defeat the Demon Lord and during the victory celebration when you see Diana, "Follow her." and then select "Yes".


These are all general notes from different routes concerning Diana's death and how to avoid them (or reach them.) If you want to achieve one of the Trainer achievements, you will have to keep Diana alive for the vicory celebration.

Erik's Route:
"Call out again!"
This option will lead to Diana's death.
"Grab Diana!"
This option will keep Diana alive.

Sam's Route:
In Sam's route, Diana's death in inevitable.

Damien's Route:
"Calm Damien down."
This option will keep Diana alive.
"Let him attack."
This option will lead to Diana's death.

James' Route:
"Don’t."
This option will lead to Diana's death.
"Stop him."
This option will keep Diana alive.

Matthew's Route
"ZECAERU!"
This option will lead to Diana's death.
"SAERO!"
This option will keep Diana alive.

Every ending comes with a letter. By putting the letters together and rearranging them, you will get the password to enter under the "Bonus" section of the main menu.

You must input the password using ONLY capital letters and NO spaces.

Here are the scrambled letters:
EESYEPCRTTAIEHN

Below is the unscrambled set of words.
THEYRESTINPEACE

If you input the right password, you'll be rewarded with a short video and an achievement.

Warning: Some of the CGs are unlocked by viewing the mature scenes in the game.
I recommend setting the "Skip Forward" setting to "Skip all" and "After Choices" to "Skip" in order to speed through these scenes if you still wish to unlock the CGs.
Information with italicized text is a warning that a mature scene will follow. Please take caution!

1: Mirth: This unlocks automatically, only if you choose to train alone when given the option to choose your trainers near the beginning of the week. Otherwise, you will miss this CG and the third.
2: The War Room: This will be automatically unlocked as you progress through the story.
3: Demon Training: This unlocks automatically shortly after meeting Mirth.
4: See below!
5: Saero & Diana: When given the option to explore the castle, choose the following.
Explore > Left > Left

4, 5-9: Tender Moments
To unlock these, you will need to do at least two run throughs on two different routes. (The first for four CGs, the second on a different storyline for the last.) Make sure on your second run you choose a different incubus storyline, or else you won't get your missing CG.

You must decide not to train with any of the given trainers when Diana prompts you. The CG's will then be automatically unlocked as you progress through the story.

NOTE: You may be able to see all four scenes even after losing your trainer but the most reliable way I've found was training alone initially. (Please do leave a comment if you've found otherwise!)
