Hello! This is a guide how to get every ending in the Cainabel story!
I will explain how I personally got the endings, that includes the order of the routes, but if anyone finds an alternative to any of them or any mistakes, let me know, so I can edit the guide!
This is also my first guide so any criticism or tips are welcome!

The choices that don’t have a character’s name is a neutral option and won’t affect anything much to my knowledge.

The order that I used to get all the endings was this but I don't think the order matters as much, except you can’t access any of Jereme path’s routes before completing at least one route in Jevite’s path:
Fin - Adage - Ulrik - Jevite
Yune - Ines - Eltcreed - Jereme

I personally played through all of Jevite path's routes first and then did Jereme's.

If a selection of choices is not mentioned, that means that it doesn’t matter which you choose as they won't affect the story. Inside the routes, I’m only including the choices that have any effect on the affection bar.

For starters, you can get 8 CGs for the 'Others' section in the gallery, for that you just play through the Grand Ending Story under Bonus Scenarios.

To get to a route, choose the answers corresponding to the character. To get Jevite's route, make sure to separate affection equally between Ulrik, Adage and Fin until you meet Jevite.

• I'll carry your things. ( + Adage)
  
• Fin and I will guarantee your safety. (+ Fin)
  
• Is there anything I can do to help?

• Stay behind with Adage ( + Adage)
  
• Go with Ulrik.

• Wait at the restaurant ( + Fin)
  
• Go together (+ Ulrik)
  (These choices only appear if you decide to go with Ulrik)

• It doesn't bother me at all (+ Ulrik)
  
• I am a little scared (+ Fin)
  
• I'm worried about the other two (+ Adage)

• Canned food (+ Fin)
  
• Sweets (+ Ulrik)
  
• Just water... (+ Adage)

• Be friendly (+ Jevite)
  
• Be formal.
  
• Be authoritative.

• Who are you, anyway?
  
• Let’s hurry inside (+ Jevite)

• I want something sweet.
  
• I want something traditional
  
• I want a local specialty.

After this choice, make a save no matter who you pursued first.
[SAVE 1]

If you choose all the options for Fin, you should have his route now. To get his ending, "Unwavering Feelings", choose positive choices if possible, otherwise choose neutral options.

• … (+ Jevite)

• I’d encourage her to turn herself in. (+ Jevite)
  
• I’d let the law handle it.

To get his ending, "Blank Slate" Start over with game. Since it’s gonna be the second route in Jevite’s path, there’s a new option/choice at the start, feel free to make SAVE 2 here before making the choice but not mandatory.

• Accept right now. (Jevite’s path)
  
• Consult with family first (Jereme’s route)

[SAVE 3]

After choosing “Accept right now”, follow Jevite path - common route guide above and choose +Adage options. Then you should get to his route. Again, choose positive options, if possible, otherwise choose neutral.

• You’re very attractive
  
• Maybe you’re too self-conscious? (+ Adage)
  

• You look so dashing (+ Adage)
  
• You’re just like a doctor.

• I can’t
  
• … (+ Jevite)

To get his ending, "Flight" , Load SAVE 3 and choose +Ulrik options.

• You seem like a very cautious person.
  
• I’m glad you trust us. (+ Ulrik)

• I can’t
  
• … (+ Jevite)

• I’d encourage her to turn herself in. (+ Jevite)
  
• I’d let the law handle it.

To get his ending, "The Sun <Mifalna>" Load SAVE 3 and separate affection equally between Ulrik, Adage and Fin in the common route until you meet him, then choose positive options for him. After saying “Let’s hurry inside” you should have a little more affection with Jevite than with the others. Once you get to this route, choose positive options for him, if possible, otherwise choose a neutral choice.

[SAVE 4] Make sure to save BEFORE making a choice here:

• Ask about his skill with the sword (+ Jevite)
  
• Ask how many women he’s tried to pick up.

• I can’t
  
• … (+ Jevite)

• I’d encourage her to turn herself in. (+ Jevite)
  
• I’d let the law handle it.

To get Other Ending 1, "And Everyday", Load SAVE 1 and choose all the positive options for Jevite, if possible, otherwise go for the neutral options.

To get the Other Ending 2, "Blood Relations and Family", Load SAVE 4 and choose any answer that IS NOT +Jevite.

Load SAVE 2 or start over with the game and

• Accept right now. (Jevite’s path)
  
• Consult with family first (Jereme’s path)
  

[SAVE 5]

• It’s hot… (+ Ines)
  
• It’s beautiful (+ Yune)
  
• It’s nothing but sand (+ Eltcreed)

• Introduce yourself. (+ Jereme)

His ending is titled "The Pursuit of Justice. To get his ending, choose positive choices for him, if possible, otherwise choose neutral choices.

• So as long as it’s in moderation… (+ Ines)
  

To get his ending, "Throughout Eternity" Load SAVE 5 and choose positive answers for Yune, or stay neutral if none of his positive choices are available, then you should get to his route.

• About personal embarrassments? (+ Eltcreed)

To get his ending, "The moon <Relva>" Load SAVE 5 and divide the affection between Eltcreed, Yune and Ines unitl you meet Jereme. Then choose to Introduce yourself. If you happen to have equal affection with Jereme and one other character, you will get a prompt to choose which route you’ll end up in. In that case, choose Jereme. After either options, make a SAVE 6.

• I’d like to pet her.
  
• Not particularly. (+ Jereme)

• Talk about the king’s decision. (+ Jereme)
  
• Talk about the law in the Heights.

As you’re max affection with him by now, the rest of the choices won’t matter so choose whichever you’d like.

To get the Other Ending 3, titled "Undone by History" , Load SAVE 6 and DON’T choose positive answers for Jereme.

After that one, you should have all the endings from the Cainabel story!

To get the final CG for each character, just watch through every Bonus Scenario for each character, you’ll get the CG from the Epilouge.

After you finish all 3 endings in New Theory, you’ll get a CG in the ‘others’ category as well.
