From top to bottom: A sword in Sparkling (sakura petals floating over the portrait), normal, fatigued, and severely fatigued states.
Fatigue is the exhaustion level of a particular sword from being sent out on too many sorties. As fatigue level worsens, swords tend to perform more poorly in battle.
Swords generally become exhausted as they are sent out on the Front Lines or Expeditions. Certain actions will increase or decrease fatigue by specific amounts.
Statuses
Fatigue is calculated using a numeric system, in which different actions will add or subtract from a sword's fatigue value. The swords display different colored background statuses, depending on the level of fatigue they have.
The exact effects of each status are currently unconfirmed. Hypothesized effects are listed below.
| Fatigue Value | Status | Effects |
|---|---|---|
| 50~100 | Sakura Fubuki (Sparkling) | Increase in fighting ability (+20%) |
| 20~49 | Normal status | Normal status (±0%) |
| 6~19 | Fatigued | Decrease in fighting ability (-20%) |
| 0~5 | Severely fatigued | Severe decrease in fighting ability (-40%) |

Recovering From Fatigue
Formation Page Screen
Item List
As outlined above, the easiest way to recover from Fatigue is to stop going on Front Lines with a sword until they return to normal status on their own. If a sword is fatigued and damaged, repairing them with the use of a Help Token will instantly restore their Fatigue to default levels.
Another way to recover fatigue is to use Sennin Dango, Makunouchi Bento, or One Bite Dango. Using these items will instantly recover your swords' fatigue. The items can be purchased from the Shop. All three items are one-time use item, so use them wisely.
To use any of the three items, go to your Formations page (疲労回復), click the green 'Restore Fatigue' (疲労回復) button, and pick an item you want to use.
Sennin Dango
Sennin Dango will instantly recover swords from fatigue. The item is applied to the current sword members in the selected party.
Makunouchi Bento
Makunouchi Bento will grant Sakura Fubuki status to all swords in the party. Like Sennin Dango, the item is applied to the current sword members in the selected party.
One Bite Dango
One Bite Dango will greatly recover fatigue of a single sword when it is given to one sword. It will also grant Sakura Fubuki status to that sword. Additionally, you will be able to hear special lines when giving One Bite Dango to the swords.
Notes
A quick way to recover Fatigue and put a sword in Sakura Fubuki status is to put them by themself on a team and repeatedly go to Map 1-1. They will always experience a net gain in Fatigue levels, as they are always the Captain and MVP, even if they are above the level cap.
A sword can also be assigned the captain of the party and brought on longer maps with more battle nodes (Eras 4 and 5). If the team travels through at least three battle nodes, the captain will experience a net gain in Fatigue levels (i.e. become less tired).
