Flower Memories / フラワーメモリー, shortened as FM, are things you can attach to individuals to power them up. They were introduced on Sep 2, 2019 and replaced Promotion Abilities. FMs have rarities between three to six.

How to Obtain

3* FMs can be bought from Wares using various common currencies: mid level equipment gacha seeds, gacha seeds, gold, sun medals, and LC. Their stock does not expire, but only a limited amount is available to be bought. Specifically, you can buy up to 50 of each FM.

4-6* FMs must be obtained from the Flower Memory Gacha / フラワーメモリーガチャ. Rolling the gacha requires Memory Seeds / オモイデ種 or Flower Stones. Memory Seeds can be bought from Wares, bought with Real Money alongside FS, obtained from Campaigns, etc.

Your existing FMs can be viewed under the Confirmation / フラワーメモリー確認 screen. The current maximum capacity is 300 1000 2000 and it cannot be expanded at this point in time.


Like how Promotion Abilities behaved, installments are maintained on a per-Set basis. For example, you could give your one and only 4* Lilac a Speed Down FM in Set 1, but her FM could be assigned differently in sets 2 through 12.


Installing an FM on a knight gives them a max HP/ATK/DEF boost. These boosts are based on the FM's rarity, level, and unleashes.


Each FM has an ability that will affect Combat and/or Subjugations. An FM's ability can be empowered by unleashing it.

Memory Score

Each FM has a Memory Score / メモリースコア associated with it based on it's rarity and unleashes. The combined memory score of all knights in a set have an impact on the dropped items in Memory Dungeons. You can see a set's total memory score above the 1st squad. Unleashing a FM 4 times (the maximum) will increase its Memory Score by 1.

  • A bronze FM will give a Memory Score of 2 and cannot be unleashed.
  • A silver FM will give a Memory Score of 3, which can be increased to 4 upon being unleashed four times.
  • A gold FM will give a Memory Score of 4, which can be increased to 5 upon being unleashed four times.
  • A rainbow FM will give a Memory Score of 5, which can be increased to 6 upon being unleashed four times.


FMs can be attached to knights from the Flower Memory Installation / フラワーメモリー装着 screen, or from the character composition screen. Either way, the FMs you assign are on a per-set basis, so keep in mind which set number you are using.

From Character Management, you can assign FMs. The green button with white bars toggles showing the FMs on this screen. If you have FMs visible from here, you can just select an FM slot on a character to assign an FM to her.

FM slots are always visible when selecting party members

If the FMs are hidden, select a character to go to the character selection screen. At the bottom of the screen, you can see your currently selected party and each character's FM slots. Either click on a slot or click on the violet Flower Memory / フラワーメモリー button at the upper-right to choose FMs for characters. When you are done with your assignments, you must press the large, red confirm / 決定 button at the bottom-right to save your assignments. Going to any other screen discards your changes.

Power up FMs with a process called Flower Memory Strengthening Synthesis / フラワーメモリー強化合成. Synthesis requires character materials called Painters / イロドール / irodooru to give experience to the FM.

Painters can be obtained by Refining Forge Spirits / オキタエール of any type except Personal Equipment Forge Spirits (the Nazuna bot ones). Painters can also be bought for various currencies from Wares.

See: FM Synthesis.


FM Diamonds

An FM unleashed 3/4 times

Flower Memory Unleashing' / フラワーメモリー解放 is the process of combining the same FMs together (aka "dupe fusing"). The unleashed FM gets a higher max level and a max HP/ATK/DEF boost. If the FM has been unleashed 4 times (the maximum), then it will also gain a powered up ability and a higher Memory Score. The FM's Unleash Status / 解放状態 can be seen from the diamonds on an FM's particulars / 詳細.

Instead of fusing dupes, you can use character materials called Memory Flowers of Kodaibana / コダイバナの記憶花 to unleash FMs. You can buy these from the Wares with Rainbow Medals / 虹色メダル. (Hence, they are extremely expensive in terms of Real Money).


You can sell FMs from the Flower Memory Selling Off / フラワーメモリー売却 screen. FMs that are equipped or locked cannot be sold. Sold FMs give you gold.

Memory Dungeon

A Memory Dungeon / メモリーダンジョン is a set of stages related to some memory. Clearing these stages gives you a set amount of Memory Stones / メモリーストーン which you can use in Wares.

Each stage in a dungeon has a Recommended Memory Score / 推奨メモリースコア. If you meet or exceed that recommendation with the combined memory score of all characters in your set, then clearing the stage gives you Memory Crystals / メモリークリスタル alongside the usual memory stones. Like the memory stones, the memory crystals are used to buy things from Wares.


From the Office, you can go to the Flower Memory Reference Book / フラワーメモリー図鑑 to look at any FMs you've obtained. You can see their picture in full size and read flavor text about them.

Comparison With Promotion Abilities

For veteran players more familiar with the now defunct Promotion Abilities / PAs, this section gets you up to speed to using FMs instead. To start with, here are some similarities between the two features.

  • PA and FM assignments are both stored on a per Set basis.
  • Most PAs and FMs can have their abilities powered up.
  • The PAs veterans are familiar with happen to be the 3* FMs you can buy from Wares.

Now that we've covered the similarities, here are some differences.

PA and FM Differences
PAs only needed to be bought once. You can obtain multiple copies of the same FM.
One PA can be set to as many knights as you wanted. One FM can be set to only one knight per Set.
PAs did not give a max HP boost. FMs give a max HP/ATK/DEF boost.
PAs were strengthened on a per character basis. FMs themselves must be strengthened.
PAs were strengthened using Sources of Ability-Nurturing / アビ育成の源. FMs are strengthened with Painters / イロドール.
PAs had nothing like unleash. FMs can be unleashed.
PAs had nothing like a memory score. FMs have a memory score.
PAs could not be given to the Whaleship. FMs are installable for the Whaleship.

Proof of Pest Subjugation

Finally, it's worth nothing that Sources of Ability-Nurturing / アビ育成の源 has been replaced by the item called Proofs of Pest Subjugation / 害虫討伐証. Although the former was used to strengthen PAs for knights, the latter is just currency used for Wares.

To Be Implemented

Not everything has been implemented yet. This is the list of planned features.

  • "Automatic Equipment Feature" for the character composition screen
  • "Unleash Feature" for the character composition screen
