From Manga Inn: Long ago, in the far reaches of space, there existed a world as pure and blue as the Earth. And on this world, there lived two "Queens" with the power to control it. When the world is thrown into chaos by one of those queens, a young boy and a young girl must stand up to challenge her for the sake of protecting all that they hold dear.
Tropes found in ''Tail Star'':
* AChildShallLeadThem: Sanagi [[spoiler: the only living tail-hunter]] and Mayu [[spoiler: the future White Queen]].
* AnyoneCanDie: [[spoiler: Aside from the Elder, Sanagi, Mayu, and about a dozen others (mostly children), everyone in Ageha Village is graphically murdered about two chapters after we meet them.]]
* AttackItsWeakPoint :
* BigBad: [[GodSaveUsFromTheQueen The Black Queen.]]
* BalanceBetweenGoodandEvil [[spoiler: Over use of the Queens powers will slowly destroy the world as long as a white queen is not there to nullify the black queen ]].
* ChessMotif: There's also a White Queen.
** LightIsGood, DarkIsEvil / ColorCodedForYourConvenience
* UltimateJobSecurity : [[spoiler: Averted as the Black Queen will order your death if you overstep your position.]]
* DownerBeginning: The story begins with the White Queen's death.
* CombatTentacles / LivingWeapon / PrehensileHair: The King Tails have a tail attached to their heads that can be used like an EpicFlail or [[WhipItGood a whip]]. The tails are extremely hard to cut and [[spoiler: can cause a mental breakdown if severed. ONE Star soldier killed almost everyone in Ageha, and all the tail-hunters, and it's implied he wasn't even that high a ranker]].
* EliteMooks : Many
** The 34 king tail tail hunters of Ageha are legendary masters able to fight on even footing with the shooting stars
* MaskPower / TheFaceless: The Elder. [[spoiler: Until recently. It's implied the other survivors had no idea what she looked like.]] The Black Queen also wears some sort of mask.
* MeaningfulName: Ageha means butterfly; [[spoiler: future White Queen]] Mayu means cocoon.
** [[http://www.mangainn.com/manga/chapter/96071_the-queen-s-justice/page_20 All the King Tails are named after comets and astronomers.]]
** UnfortunateName: The Black Queen's guards are known as [[spoiler: The Queen's hymen]].
* TheEmpire: Originally there were two kingdoms of light and dark. However after the White Queens demise the kingdom of light surrendered and were either destroyed or incorporated into the dark kingdom forming the current empire.
* TheMole: [[spoiler: Imperial fighter Yaeha, who's also deceased tail-hunter Sam's sister.]]
* MoodWhiplash: The art is incredibly cute and then [[spoiler: Ageha Village is slaughtered.]]
* OneManArmy / PersonOfMassDestruction / SuperSoldier: The King Tails.
* SigilSpam: The Ageha (Butterfly) motif. [[spoiler: The villagers ditch everything butterfly-related so they can hide among other refugees.]]
* WhipSword: Yaeha keeps a whip-like katana(s) up her very tight sleeve.
* YouHaveFailedMe: Do not presume to know what the Black Queen thinks!
