[[folder:Rashinban Musu / Compass Girl]]
* TheDreaded: Every Admiral is at the mercy of the compass. Pray that the compass fairies don't send your fleet into a dead end after a series of hard fought battles.
* FourTemperamentEnsemble: The four Compass Fairy fit this, even with their limited script.
** Sanguine: The one with a chick. Her face in permanent X3, she talks in MotorMouth, and she's always trembling with excitement every time she spins the compass.
** Choleric: The one dressed like a witch. The most noticeable of the four, dressed gaudily even for the fairy's standard but her speech bubbles always filled with tad bit of trivia.
** Melancholic: The one with hairclip. Doesn't really stand out, but most hard-working. Ambivalent of anything.
** Phlegmatic: The green-haired one. Always looks sleepy, doesn't talk much, and even that she's pretty apathetic.
* TheDreaded: The greatest enemy no Admiral ever wants to encounter: [[spoiler:a connection error.]]
* GirlishPigtails: [[HairDecorations With ribbons.]]
* BadassAdorable: They man every piece of equipment and pilot every plane in the game. And they are cuter than a box of kittens.
* TheGreatestStoryNeverTold: Very rarely appear in media, despite being essentially crew of the ships/pilots/maintenance personnel.
* FairyCompanion: For the ship girls. due to them manning and operating all the equipment on behalf of the shipgirls. In some fanworks they tend to follow around the girls in day to day activities as well.
* LoadsAndLoadsOfCharacters: every equipment type has a unique fairy sprite [[note]]With the exception of 16inch Triple Gun Mount Mk.7 + GFCS, which shares a fairy with the base 16inch Triple Gun Mount Mk.7, but with another fairy added in, and the 38.1cm Mk.I/N Twin Gun Mount, which has the same fairy as the base 38.1cm Mk.I Twin Gun Mount, but with her pose changed.[[/note]]. Currently there are well over 150 equipment fairies, plus construction workers and NPC's.
