* AlternateCharacterInterpretation: Recently, Suzu. Is she ''still'' as innocent as she was at the beginning, even though her being a ClingyJealousGirl is becoming more and more blatant as time passes?
%%* CrossesTheLineTwice: Machi, who pulls off ComedicSociopathy to ''insane'' levels many times, and yet she still retains the "comedic" part.
%%* EnsembleDarkhorse: Dear lord, it's Machi
* FridgeHorror: [[spoiler:Suzuran]] returning as a ghost. Whether she's dead or not (the latter is still possible thanks to the island not being a stranger to the supernatural) it still begs the question: ''what'' really happened to her that no one even found out about it?
* FridgeLogic: Apparently, it took Beniyasha ''less than a day'' to write and publish an adventure based on his antics.
** [[FridgeBrilliance Perhaps he had the book written, then went out and had the antics]].
* IronWoobie: Ikuto. Before coming to the island he was drifting on a life preserver for seven days without food or water. He spends the first episode/book futilely throwing himself against the same few whirlpools until it's absurd but only until he points out that he did that to '''learn''' their flow and sneak between them (there's an even larger one beyond it, sadly). His grandfather puts him through TrainingFromHell and its given him a fear of heights. In a free-for-all game of tag for marriage the day after he arrives, he gets dropped from a tremendous height and thrown an incredible distance and loses only by an involuntary gesture of bravery on his part. And the hits keep coming. On the other hand, with renewed training, he becomes a BadassNormal who manages to outwit or fairly beat four of the island's most powerful champions in a span of two days.
* LesYay:
** Ayane's your soul mate, Michiru? Okay, [[SarcasmMode no lesbian undertones to that...]]
** Also, Karaage's little comment about it.
** In one chapter, Chikage ''really'' enjoyed playing with Suzu's hair. Again with chapter 11. Sure, she thinks it's ForScience, but...
** The scene with Suzu and Chikage in chapter 11 is a rather blatant example.
%%* {{Moe}}
* NightmareFuel: When Ikuto falls into the water in the beginning of the anime, the shadow of a ''very'' large sea monster with [[RedEyesTakeWarning glowing red eyes]] appears.
* OneSceneWonder: One picture shows Kokoro and Hanzou getting married...''upside down''.
* ValuesDissonance: Some, in that Yashiro, [[spoiler:Machi and Ayane's great-'''grandmother''']] claims to be 64...which means that each generation would have had to give birth at age 16.
* TheWoobie: Suzu. Both parents missing, and her feelings are conflicted over wanting Ikuto to either stay or leave the island. Ouch.
