In episode 11, Nozomi gets an 18 on a math test. She studies with Coco and company and manages to raise that up to a 35 by the end of the episode. In the same episode, Nozomi manages to finish reading a book for the first time in her life.
Audible Gleam: This is Pretty Cure. You won't get five minutes into an episode without sparkles.
Bait-and-Switch Credits: While they're mostly accurate, the first opening briefly features Karen showcasing her musical talent the violin. In the series proper, the only instrument she's known to play is piano.
Beta Couple: Nuts/Komachi, with Coco/Nozomi as the Alpha. In addition, either Syrup/Urara or Karen/Kurumi could count as the Gamma Couple.
Beware the Nice Ones: The very first sign that the really nice Komachi needs to be watched out for was when she suddenly slammed the table and scolded the crowd that pestered Karen for her Student Council President permissions. When Hadenya pushed her too far, she not only effortlessly block her attacks like a total Badass, but shows that for a Barrier Warrior, she's also capable of unleashing untold destruction with that barrier.
Big Eater: If you're not Komachi, raise your hand.
Big Fancy House: Holy crap, Karen! And that's not even including her private island, or private mountain resort, or just countless of other smaller houses...
Bishōnen: Coco/Kouji, Nuts/Natsu and Syrup/Shirou, to hilarious extents on Nuts' part. Mukadia, disguised as Momoi Kyousuke, also counts.
Bittersweet Ending: The first series. Although Nightmare is defeated and Coco now has the means to restore the Palmier Kingdom, he and the rest of the Palmier Kingdom citizens have to separate with Nozomi and friends, and to reach the Palmier Kingdom, the Precures give up their ability to become Precures and resume their life as normal girls. Not to worry, the second season's preview is right after the ending credits, so we know things will be less bitter soon.
In Second Season: Eternal dies, but Flora dies too, but reborn in seed form, the girls take care of this seed, the Cure Rose Garden are free from visit, the cirls care from Palmier Kingdom citizens and get our dreams.
Book Ends: The series proper begins with Nozomi running around a corner and crashing into Coco, who catches her. Go Go ends with Nozomi running to deliver a letter to Coco via Syrup, only to run around the same corner and into Coco himself, who again catches her in his arms.
Character Development: This is pretty prevalent in this series, by the end of the series, the girls have come out to be different than how they were introduced. For example, Nozomi is less scatterbrained and more focused in her dream that she found out, being a teacher. Rin is more open to her more feminine hobbies (like accessory making) while still going with her tomboyish activities (like soccer). Karen becomes less self-dependant and lonely, accepting help and also works her way to be a doctor.
Cherry Blossoms: Used to add more of a dramatic, mysterious feeling to Syrup's first scene in GoGo. And to make him look more of a Bishōnen.
Clingy Jealous Girl: Milk towards Coco, which explains most of her animosity toward Nozomi; once Crepe appears, the three of them succumb to a jealous war over the poor guy. Syrup, on the other hand, is fought over by Nozomi, Kurumi and Urara. And then there's Anacondy...
Club President: Mika is the Club President for the school newspaper, and only member by default, since her obsessive personality drove everyone else out.
Combined Energy Attack: in the form of a magic kamikaze mecha-butterfly in the first season, and the form of a giant man-eating rose in the second season.
Continuity Nod: In episode 40, Nozomi doesn't figure out that Otaka-san is the Chief Director until Rin says it. She and Urara have a Big "WHAT?!" reaction. This happens again in episode 44 of GoGo with Santa Claus.
Cool Mask: Pretty much the whole point of the Nightmare Group.
Defeat Means Friendship: Despariah, Dark Dream. Seems to be an exclusive power of Nozomi's: the other Cures just kill their enemies. However, as seen in the first movie, even Nozomi has her limits. Enemy subordinates, though? Tough luck... unless you're Bunbee.
Diet Episode: In one episode, Coco goes on a diet because he got fat (although you never really see the difference in his human form) from eating too many cream puffs.
Disappeared Dad: Not in-universe (except for Taro Minazuki), but all five characters' fathers seem to have a lot of trouble getting screentime. Only Urara's and Nozomi's ever appeared, and even then their combined total appearances are in the single digits.
The Dragon: Kawarino, who has his own Dragon in Bunbee.
Fractured Fairy Tale: Milk fractured Cinderella in the first season: Casting Nozomi as a super clumsy Cinderella, Urara as an equally clumsy Good Witch, Rin, Karen and Komachi as the Definitely-Not-Wicked Stepsisters and Stepmother... and every of the cast got Medium Awareness that they're in a Cinderella story. It was only done midway before the midnight ball done, but Rin and Karen still complain on how they're cast as the 'villains'.
Frilly Upgrade: Wings Of Justice; later, Jackets, and later, Even Bigger Wings of Justice.
Gag Sub: Yadokan and Isogin have almost the exact same lines, some fansubbers still translate them in completely different ways.
Gratuitous English: right there in the title. Also notice that the team says "Yes!" rather than "Hai!" when they are about to do something flashy.
Gratuitous French: The school's Meaningful Name, L'Ecole des Cinq Lumieres, literally translates to "The School of the Five Lights". This has no direct relationship with the five lights that protected the Palmier Kingdom, but it is where those five lights found the protagonists so they can become Pretty Cures.
Laser Blade: Played straight by Cure Aqua's sword in the movie, even leading to some fantastic Blade Locks with Dark Aqua's very own Laser Blade. Subverted as the Cure Fleurets are never used for direct combat.
The Leader: Nozomi is chosen as one as she was the one who gathers them. However, in Go!Go!, Nozomi claimed that she's not one, and they probably don't need one, when Bunbee offered himself to be the Precure leader.
Lethal Chef: Though they got better during episode 21 of ''GoGo''.
In the first season, Kawarino managed to put Despair Mask to all the Cures and rendered them despairing and immobile... Until Coco leapt through and first snapped Nozomi out, followed with her snapping the rest.
Anacondy petrified all the main Cures and turned them into Eternal collections as the Eternal Director makes his flight to Cure Rose Garden (oh and he just killed Anacondy afterwards). Even with Milky Rose, she won't be enough to single-handedly beat the Director and she doesn't know Eternal base's interior to find where the Cures are taken. But suddenly, Bunbee comes in and nonchalantly showed the way just before he called it quit for real, so Milky Rose and the other mascots reach the Cures, give them a pep talk that restore them from petrification so they can catch up and deliver righteous beatdown to the Director.
Oba San: Karen's not really this, but it is the source of her Fan Nickname. Although Rin ribs on this a bit during the first movie, when Karen tries to act like a princess (which, by the way, means lots of Noblewoman's Laugh), Rin said that she looks more like a queen than a princess.
Shaggy Dog Story: the entire Dream Collet plotline. Though Tropes Are Not Bad, because this trope becomes a point on how Coco is able to rally the Palmier Kingdom to break away from the Nightmare Mask and rebuild the Kingdom again even when the Dream Collet ran out of use by Desperaia.
Ship Tease: Lots, mostly involving Karen or Nozomi.
Surprise Santa Encounter: Episode 44 of GoGo. Santa Claus is attacked by Mucardia who steals his sleigh and Santa falls on earth while losing his cloak and hat and catching a cold. Syrup and Urara find him in a park where he collapses, so they bring him to Natts House. They later bring his sleigh back after they purified it as a Hoshina, and Santa goes back to work. While everyone else figures out he's the real Santa when he's about to go, Nozomi and Urara take it longer.
Talkative Loon: Not so much of a 'Loon', but Queen Bavarois. Once she talks, she just won't shut up. She could easily pass as a less powerful long lost sister of Excalibur.
Uncanny Family Resemblance: Komachi and her sister Madoka look so alike that anyone who doesn't know Madoka immediately mistakes her for Komachi, which is played for humor as Komachi and Madoka are a Sibling Yin-Yang. (Incidentally, they also share a voice actress.)
Verbal Tic: The mascots, as in every Pretty Cure series, use some variation on their names; also, Rin ends some of her sentences with "nano" and Nozomi with "mon".
Where The Hell Is Springfield?: They're supposed to be in the Minato ward of Tokyo, but you couldn't tell by looking — they instead seem to be in some twisted Euro-Japan that highly confused viewers as to where they actually were.
You Have Outlived Your Usefulness: In the first movie, when Dark Dream makes a Heroic Sacrifice, Shadow says that she had outlived her usefulness and he was probably going to kill her anyway. Later, Mukadia suffered this at the very end of 5GoGo!.
