Morale is used to measure the current morale status of a ship girl. Low morale is referred to as "Fatigue". The actual stat ranges from 0-100 and is hidden in game. The values can only be viewed by using a viewer. Ship girls recieve bonuses or penalites depending on her level of morale.

Morale naturally regenerates by 3 points every 3 minutes up to a soft cap of 49. Exceeding this cap requires sorties, exercises or gifting. Please see Sparkling for more information on how to sparkle your ship girls.

Overview

Morale still naturally regenerates while a ship girl with 49 or less morale is on sortie or expedition.
- This means that sorties which take 15 minutes or more can be done consecutively with a single fleet.
Repairing ship girls below 40 morale will reset their morale to 40.
- Using an Instant Repair can help bring damaged and fatigued ships back up to normal morale quickly.
Remodeling a ship girl will reset her morale to 40.
Newly obtained ship girls have 40 morale.
The time it takes to recover to soft cap from various fatigue states is:
- Heavy Fatigue: 30-48 minutes
- Moderate Fatigue: 21-30 minutes
- Slight Fatigue: 0-9 minutes
Morale will update after every battle.
- This means that ship girls can recieve morale bonuses mid-sortie.
Although morale has a maximum value of 100, it is impossible to hit that value with sorties. It is only possible through repeated exercises and using gifts.

Morale Effects

Status	Value	Effects
High Morale (Sparkling)	50-100	Increased accuracy and evasion in combat. Since entering a day battle reduces morale by 3, the minimum morale needed is usually 53. Increased chances of Great Successes during expeditions. Increased chances of triggering Support Expeditions.
Normal Morale	40-49	No bonuses or penalties to combat or expeditions.
Slightly Fatigued	30-39	No bonuses or penalties to combat or expeditions. Although the ship girl banner indication does not change, the Gift button will begin flashing if there are any ship girls in the fleet with this state.
Moderate Fatigue	20-29	Decreased accuracy and evasion in combat. Expeditions will fail if the fleet returns in this state. Increases the morale loss from sorties.
Heavily Fatigued	0-19	Decreased accuracy and evasion in combat. Expeditions will fail if the fleet returns in this state. The Overkill Protection mechanic changes for ship girls in this state. She will have her HP reduced to 1 instead of losing a percentage of her remaining HP.

Gifting

The Gift (給) button in the Composition menu.

Gifting is the function to feed sweets to ship girls in a fleet to raise their morale. This function is available by clicking on the Gift (給) button in the Composition menu.

The amount displayed beside the button is the total amount of Mamiya and Irako possessed.
Either, Mamiya only, Irako only, or Both sweets can be given.
- If the Gift button is flashing (), all 3 options can be picked.
- If the Gift button isn't flashing, only the latter 2 options can be picked.
Combined Fleet are still considered 2 fleets and so require separate uses.

Mamiya

Using Mamiya sets the morale of all ships in the fleet to a fixed value:

0-39 Morale: Set to 40.
40-49 Morale: Set to 50.

Irako

Using Irako increases the morale:

Of the flagship by +25,
Of 0 to 3 random other ship girls in the fleet by +25.

Mamiya and Irako

Using both Mamiya and Irako together increases the flagship's morale by +30 and the morale of the rest of the ship girls in the fleet by +20-31.

Ship girls that are below 39 morale get their morale set to 40 before the bonus morale is applied.
If the ship girls are already sparkled, the bonus morale is added on top of their current morale values.
A single use is roughly equal to 1 Mamiya and 5 Irako used individually.
Using this on a Striking Force Fleet applies the bonus to all 7 members.
