Relationship is mechanism used to describe Kirito relationship with other characters in the game.

Relationship is described through 5 levels of Affection.

Higher Affection Level with a character will unlock side quest for them and if you have reach the required point the side quest will be available.

So getting your Affection Level to max level with all character will guarantee you don't miss any side quest.

Initial side quest of each character will unlocked when you reach level 2 of Affection Level with that character

Affection Level represent Kirito relationship with that character.

Affection Level consist of 5 levels that presented by affection heart percentage :

1. Level 1 : Acquaintance [Affection heart between 1-20%]
2. Level 2 : Amicable [Affection heart between 21-40 %]
3. Level 3 : Friend [Affection heart between 41-60 %]
4. Level 4 : Close Friend [Affection heart between 61-99%]
5. Level 5 : Rival [Affection heart at 100 %]

In order to raise affection heart percentage, you can talk to the character to get affection point at the socializing area (marked with love symbol) at town/village.

• First Tier
  
  This interaction options appear when you zoom far away from the character you are talking/interacting (recommended at Affection Level 1)
  First tier has three topics you can talk about :
  
  
  1. Talk about yourself
     
  2. Talk about your partner
     
  3. Talk about love
  
  
• Second Tier
  
  This interaction options appear when you zoom a bit close (using R stick) from the character you
  are talking/interacting (recommended at Affection Level 2 and advisable during heart to heart
  minigame after you choose to share bed - refer to Pillow Talk section bellow)
  Second tier has three topics you can talk about :
  
  
  1. Talk about world
     
  2. Talk about battle
     
  3. Talk about food
  
  
• Third Tier
  
  This interaction options appear when you zoom a bit more closer (using R stick) from the
  character you are talking/interacting
  Third tier has three options you can perform :
  
  
  1. Smile at them
     
  2. Gaze at them
     
  3. Look around (avoid this option as it's generally depleted interaction bar meter)
  
  
• Fourth Tier
  
  This interaction options appear when you zoom the closest (using R stick) from the character
  you are talking/interacting.
  Fourth tier has four initial options you can perform (and two more options after you reach certain affection heart percentage) :
  
  
  1. Hold their hand
     
  2. Poke their cheek
     
  3. Pat their head
     
  4. Slide up to them
     
     Additional Options :
     
     
  5. Hug them (after Affection Heart > 60%)
     
  6. Move Your Face Closer (after Affection Heart Reach 100 %)
     

Higher tier interaction will result more affection points especially if you click when the heart is at largest size but notice that the interaction bar will drop faster.

Please notice that each character may respond differently to each topic/actions - one will have interaction bar faster while the other may slower, such as Asuna that will have interaction bar drop faster towards Second Tier interaction options and each option will increase different bar (friendship/romantic/both for each character)

Equiping Anima will help you to improve relationship easier :
Affectionate (Kirito's original Anima will help increase mood)
Lecherous (Leafa's original Anima will help increase affection heart percentage)

When the interaction meter bar is out then the interaction will be concluded.

Please look at the image bellow.

There are many type of Personality and Anima which give many effect in or outside battle.

But the most important thing is if the value of Personality and Anima goes to 100% you will unlock that peronality/anima, therefore you can copy and store it and give it to the other character, this is very useful for personality and anima that give good/useful effect such as give more EXP or more item drop.

Personality and Anima can be increase in two way :

• interacting with the character, higher affinity point gained after interaction will raise the personality and anima higher.
  
• controlling that character during battles

Additional Notes

• prize costume for a character (if that character has) can be unlocked by doing heart to heart with them when their persona and anima at 100% (max)
  
• Kirito's own personality and anima can't be increased through doing heart to heart. The only way to increase it is by using Kirito in adventure and battle until it raise to 100%.
  Please note that switch Kirito's personality/anima when it's not yet reach 100% will reset it back when you reequip that persoanlity/anima.
  

Mood level represent character mood when talking/interacting with Kirito.

Mood level is essential to initiate pillow talk with the character and higher mood will gain more affectionate point for each talk/interaction.

Mood level will increase when both Friendly and Romantic Bar meter is raise at highest point. Once the mood rise for example from Level 2 Happy to Level 3 Flustered then both Romantic and Friendship meter will back to 0 so you will have to raise it again in order to raise the mood again.

Please notice that as mentioned above, each character will have different topic/actions that will rise Friendly and/or Romantic Bar.

Also notice that once the character mood level increase, his/her reaction towards topic/actions may changed (for example topic that previously raise Friendly Bar will raise Romantic Bar instead.

Therefore to raise mood quickly you need to choose topic/action that will raise Romantic and Friendship bar to max as quick as possible (I recommend doing T2 interaction and equip Considerate Anima to Kirito)

Note :
If the mood level is 1, it's better use T1 option as T2 option sometimes deplete the interaction bar faster)

There are 5 Mood Level :

1. Relaxed/Jovial (Depend on location of Heart to Heart interaction)
   
2. Happy/Fun/Cool (Depend on location of Heart to heart interaction)
   
3. Flustered
   
4. Excited
   
5. Content

Pillow talk scene is the scene when each character try to help Kirito by verifying his memory because they are afraid that Kirito memory is distorted after sudden attack after he defeat the pontifex in the end of chapter 1.


There are several requirements in order to trigger a Pillow Talk :

1. Minimum affectionate level is level 4 (Close Friend)
   
2. You haven't got any pillow talk with other character than the one you are attempting to trigger the scene today, because only one pillow talk can occurred each day, for example if you have initiate sleep talk with Asuna today you need to wait another day to initiate other scene with other character.
   
3. The character mood level must be at level 5 (Content).
   
4. You must choose to carry the character before went to Kirito tent or you can carry them inside tent and go out and go in again in order the share bed option appear if you carry your partner near Kirito's Bed.
   Note For Silica and Fanatio as I discovered today you need to carry her outside the tent or the share bed option won't appear.
   
5. You have raised your character mood from Excited to Content on the same day.

Once all prerequirements above is meet, you will have option to share bed when you carry the character and approach the bed inside Kirito's tend in North Centoria.


After you choose Share Bed option, the heart to heart mini game will begin.

You must maxed both romantic and friendship bar on the left and right side of the screen before the interaction meter went out during this heart to heart mini game in order the scene to trigger.

If the meter runs out and both romantic and friendship bar not maxed the scene won't trigger.

That's why I suggest doing Second Tier interaction so the interaction meter won't run out before both Romantic and Friendship meter are maxed, please remember that as stated above each character may have their interaction bar drop faster while the other drop slower.


Notably easy to rise Character (interaction meter bar drop slower):
- Sortiliena
- Ronnie
- Tiese
- Bercouli
- Cardinal

Notably hard to rise Character (interaction meter bar drop faster):
- Asuna
- Deusolbert
- Medina
- LInel

Hardest Character :
- Fizel (Unable to raise her mood because bar runs out before the meter filled up)

Please check two video bellow when I try to trigger the scene for Asuna, Ronnie, Sortiliena, Sinon, Alice and Tiese in order to see everything I mentioned and explained above

Each person has different state (Personality, Anima, Affection Level) but I managed to trigger pillow talk for all of them.

And I am still not progress through Chapter 2 yet when those videos are recorded, still at collect info in Williria which means you don't need to progress through main story too much to trigger Pillow Talk.


It's also possible to trigger all pillow talk scenes at once without processing the storyline
as in this video, when I attempted to trigger all Sheyta pillow talk scenes in one go


21:22 - 30:02 (first talk)
48:49 - 1:50:45 (Process triggering her second until her last talk)

Characters with no Pillow Talk Scene currently :

• Bercouli
  
• Deusolbert
  
• Eldrie
  
• Renly
  
• ReoNa
  
• Strea
  
• Philia
  

That's all that I found about relationship in Sword Art Online Alicization Lycoris game
I will add more information in this guide if I found something new especially about personality and anima description as I haven't found every available personality and anima yet.

You can comment bellow if you have any question about the topic I am explained above and I will try my best to give the answer.

Thank you.
