Locked Out of the Loop: She's the only one of the two duos that has no idea or has suspicion that Kaoru and Michiru are Dark Fall warriors. But it's because of that, she had no doubt on each other's intentionnote Mai suspects the twins to backstab them when she finds out until she sees Kaoru saves Minori, while the twins think that the Cures luring them into a trap by false sense of security, only seeing her friends as awkward, but kind-hearted people.
Malaproper: Whenever Shitataare is involved, often with hilarious results.
She does the same to Karehaan too.
Meaningful Name: "Saki" comes from the Japanese verb "saku", meaning "to bloom", while "Hyuuga" can be translated as "facing the sun"
Attention Deficit... Ooh, Shiny!: It's not as much as she lacks focus; she has too much focus on things that tickle her fancy, usually her drawings, and it's difficult to distract her out of that. Choppy has to physically shake her out of her trance if that happens.
Hyper Awareness: This girl practically has a photographic memory and good eyes to notice that two people flying under moonlight hundred meters away are her classmates.
The Klutz: Not her, but her mother. She's an archaeologist that often has sleep attack in the middle of doing something because she's losing sleep from her work. Mai usually is the one who takes care the brunt damage of her shattered plates and scattered papers.
Last Name Basis: She calls everyone except Saki and the Kiryuu sisters with (Last name)-san. The only reason she calls Michiru and Kaoru with their given names is because their surname is the same.
Little Sister Heroine: Subtle, but it's implied that Mai becomes more resposible and well-mannered than her somewhat indecisive older brother because in the past she's an Annoying Younger Sibling. She bonds with Minori because of their shared adoration toward their older sibling and desire to shed said Annoying Younger Sibling stigma for sake of said adoration.
Meaningful Name: In Japanese "Mishou" is written with the characters for "beauty" and "fly". "Mai" translates to dance, but it can also refer to the fluttering of a bird's wings.
Nice Gal: Soft-spoken, well-mannered, and non-confrontantional. She's loyal to her friends to the point of Can't Spit It Out when she saw Michiru and Kaoru as Dark Fall warriors because she can only see them as friends and unsure whether telling Saki is a right choice for their friendship.
Because You Were Nice to Me: Their borderline Undying Loyalty and insistence to save Michiru and Kaoru from the Dark Fall, even though they are directly responsible for the destruction of their Fountain, is because the twins saved them from a falling tree, spared their lives, and allowed them to keep staying in the Fountain even though their job includes fairy-killing, long before their Heel-Face Turn.
The Comically Serious: This guy is almost no-nonsense, except regarding his nickname Karecchi. He allows almost everyone to call him that.
Enemy Mine: He dislikes Moerumba (mostly because their elements are incompatible and Moerumba rubs him the wrong way), but when it comes to fighting Precure, the combination is simply devastating. The Cures only manage to survive because when victory is almost assured, Karehan and Moerumba start fighting again, forcing Gohyan to retreat them both.
Leeroy Jenkins: Basically his Fatal Flaw; he's too impatient to attack strategically (even Kintolesky is better at this than him), using two Uzaina at once to overwhelm the girls in his arc's last episode. As warriors of Dark Fall die from using up all their Miracle Drops to make Uzainas and taking too much damage, this is an incredibly stupid move as the Cures' finisher is Twin Stream Splash... and this happens again when Gohyan resurrects all the generals. He's such a glory seeker that he ignores Kintolesky's warning and charges head on to his seemingly defeated opponents, only to get blasted at point blank twice.
Emotionless Girl: Kaoru at first. Michiru is friendlier from the beginning, but even she has her moments.
Empty Eyes: Not as dull of a color as most other examples, but there is a sense of lifelessness in their eyes. It's worse when they fight the Cures, as it makes them look inhuman. The glossy look slowly disappears as they make their Heel-Face Turn bit by bit until the eyes are completely normal-looking at the last few episodes.
Heroic Sacrifice: At the end of the Final Boss Preview against Akudaikahn, they undergo this when they save the Cures by sending them away from Dark Fall. It turns out they didn't die, but were sealed away.
Sibling Yin-Yang: Exist in subverted archetypes; Michiru might be the friendlier of the two but she's actually a type B Stepford Smiler who doesn't understand the reason of such novelties, while Kaoru is more prone of Brutal Honesty because she's insightful of her surrounding and doesn't see the point of faking her concern. Then they play it straight; when they face their inevitable fight with the Cures, Michiru quickly despairs and goes into a berserk denial, while Kaoru notices that fighting is not something that they want, makes peace with her contradicting existence and stops her sister.
Enemy Mine: The reason why she invokes I Was Just Passing Through, Thinking Out Loud, and open a portal directly into Gooyan's lair; she's so furious that Gooyan is one step away from her by capturing Flappy and Choppy, she decides to help the Cures reclaim their fairies.
Inferiority Superiority Complex: She seems to compete with Kintolesky for the title of Dark Fall's strongest, and being constantly one-upped by both him and the Cures really gets into her skin. Her interaction with the Cures really gets into It's Personal territory because of this reason, with both sides are not only physically clashing but also taunting psychologically and exchanging trash-talk.
Lady of War: Ignoring her personality, she's actually a quite graceful fighter. She opts to dodge any attack with twirling motions and redirects physical attacks with her hands, not unlike Cure Egret herself. Most visible in DX 2, when she dodges Prism Chain with a simple twirl before charging at Precure5 team, while Moerumba jumps away from the attack before it connects.
Blue and Orange Morality: Due to his Blood Knight tendencies. Early on he even says Earth isn't so bad, but he simply does not comprehend that not everyone likes fighting, or that there are more important things than victory.
Dumb Muscle: A subversion. He's not stupid, but he dislikes using strategy. In fact the first time he tries using strategy he steals Saki's school festival costume, uses it to surprise Mai...and that's it. He even admits he didn't see the point. But this doesn't stop him from using Reverse Psychology later on to lure Saki and Mai into a trap.
Abusive Father: Sending your daughters-except-in-name into Fate Worse than Death at the bottom of a lake after you blasted the hell out of them when they weren't fighting back really grants you the title, Akudaikahn.
Super Toughness: In their first confrontation with him, Bloom and Egret try to physically attack him. They end up only hurting their own limbs. He also No SellTwin Stream Splash without much fuss, claiming that he didn't even use half of his power.
Truly Single Parent: At one point the Cures note that he's basically the Kiryuu sisters' father.
Faux Affably Evil: He always speak in Keigoeven after the reveal. He taunts, he grinds morale, he destroys, but he always do those politely and without empathy. When his true form is shown, he might forgone the Japanese Honorifics, but his language is even more archaic and soft-spoken. He also becomes emotionless and more callous of everything, including his Dark Fall.
