Arc Number : The number nine is important in Nileniran culture, due to their nine goddesses.
Asskicking Equals Authority : The appointment of High Commanders in Nilenira is supposed to be this, but tend to be more based on winning the favor of powerful families. However, this trope is still played straight in Nilenira due to the fact that inheritence only goes to girls who have completed the Training from Hell.
Author Avatar : Nehpeus iln Roblos, the youngest and least important member of the Roblos Clan.
Black Sheep : Dilsinet ler Paldrea. Also, Jirdrea's sister Belisdrea.
Evil Albino : Dralnea ler Reltrea appears to be a villain at first, as her first act in the story is killing a lower-class girl for not saluting her. This will be subverted in later chapters.
Exact Words : Relbacia invokes this when she promises to let the crew of a merchant ship that she and her brother capture live. She promises that she will not kill them, but reminds them that ordering them overboard will cause the water to kill them, not her.
Family Theme Naming : There are Four Robloses in a row in the Roblos Clan of Pirates, and, in Nilenira, there are several Jirdreas in Jirdrea's line, along with several Dilsinets in Rilsent and Dilsinet's line.
Knight Templar : Ernalk Osarbin has yet to appear, but his actions forty years before the story in trying to eliminate the Cusubolmi pirates turned the Roblos pirate clan into in-universe Dracos in Leather Pants and Osarbin into The Dreaded in Cusubolm, which suggests this trope.
Matriarchy: Nilenira is the "Patriarchy Flip" variety.
Transparent Closet : Talisent ler Geltrinea, Jirdrea's friend, is obviously attracted to her.
Tryto Fit That On A Business Card : All of the High Commanders of Nilenira have rather long titles, but the Supreme Commander takes the cake: Her Grand Ferocity, Supreme Commander Rilsent ler Paldrea ler Freldea ler Rilsea ler Dilsinet ler Tilnidea ler Paldrinet ler Rilsent ler Nilsinet ler Dilsinet ler Drelsea ler Freldea ler Dilsinet Vecendishbane ler Jirsent ler Paldrea, Defender of Nilenbay and all of Nilenira, Sword of Prelsient, Goddess of Wind, of Nilensent, Goddess of Earth, of Gilserea, Goddess of Fire, of Tarilsea, Goddess of Water, of Felnisent, Goddess of Souls, of Jirdrisent, Goddess of Justice, of Bilasent, Goddess of Desire, of Relterea, Goddess of the Harvest, of Desarlea, Goddess of War, and of the Nileniran people, Queen of Nilenira, and Commander of all Nileniran armies and navies.
