How to Raise Affinity and Oath a Ship

This is based on my experience. Feel free to correct me if you find any error.

Raising a ship's affinity

Ships have affinity level that can be increased, starting from "Stranger", then turning to "Friend", "Crush", "Love", and finally, once you've given them a ring, "Oath".

From what I've observed, simply using the same ship over and over again won't raise the affinity to the max. Each stage of affinity can be achieved by doing specific actions. Those actions include:

1. Using the ship in 10 battles
2. Setting the ship as secretary and do 10 battles. Using the ship is optional*
3. Raising the ship's level to 100, then do Cognitive Awakening**

By doing these actions, the ship's affinity will increase by one stage until "Love".

*= Point 1 and 2 can be stacked, meaning if you set a ship as a secretary when she still has "Stranger" affinity and go into battle 10 times with her, the affinity will jump to "Crush".

**= Cognitive Awakening can be done by raising your ship to level 100, collecting their M Isomer by fighting them in the story mode, and exchanging them for Cognitive Chips in Akashi's store. Once you have, simply go to Dock and open the ship's status screen. Press Triangle (PS4), Y (XBOX), or I (Keyboard) to proceed. (Need to finish story mode first, up to chapter 6 and S-rank all the stages)

Buying the Promise Ring

Once you've raised a ship's affinity to "Love", it's time to buy a Promise Ring for them. The rings are available for purchase once the ship's affinity became "Love".

To buy the ring, you need Heart Tokens. Heart Tokens are unique to each ship, meaning you can't buy Shimakaze's ring with Suruga's Heart Tokens. Heart Tokens can be acquired through two methods:

1. Watching an episode for the first time in Episodes mode. You can only get Heart Tokens once from each episode.

2. Clearing Extreme Battles. You can get a ship's Heart Tokens by fighting them. For example, clearing stage 1 will get you Shimakaze's and Yukikaze's Heart Tokens.

Once you've collected 25 of Heart Tokens, you can exchange them for Promise Rings from Akashi's store.

Marriage

With the ring in your possession, simply go to the Dock and open the ship's status screen. Press Triangle (PS4), Y (XBOX), or I (Keyboard) to start the marriage.

And you're done! The affinity on your ship will now show "Oath". I haven't checked it, but one of the tutorial said by doing this, your ship's status will be boosted by a certain amount. Enjoy!

You can revisit story mode anytime you want from the main menu. As for the Heart Tokens, like I wrote in the guide, is to be exchanged in Akashi's store for the rings.

What if you didn't S rank every single fight? is there a way to re-do them after story mode is done? and what are heart tokens for?

You have to collect enough isomers for a cognitive chip, you need to complete story mode completly and have S rating in all missions in order to use the cognitive chip, if it isn't working go replay some of the chapters and find which one isn't S rank. To marry a ship you need to cognitive awaken her, have her as secretary for 10 battles, and use her in combat for 10 battles. After that you can oath her if you have the ring. You can find heart tokens by watching episodes and by completing extreme battles that have the specific ships as adversaries.

That's right. Glad to let you know.

and based on that i can assume that awakening a ship is equal with bringing her to battle 10 times..

[MarilynMesum]

ah... thanks for the info then.. because i have been awakening my ships since stranger.. ahahaha.. so they only advance to friendly after i awaken them.. that's why i've been grinding like hell to get her all to love..

[A/Z]

I see your point, but you don't have to necessarily do that. If you got the ship to "Crush" through 10 batlles and setting as secretary, you can advance it to "Love" by doing Cognitive Awakening.

[MarilynMesum]

oh sorry.. forgot to mention, 10 battles after she's on crush to advance to "love".. and after you set her as secretary..
