- Accidental Innuendo: Done by Yuuka in episode 9, after Usui eliminates Himegami from the water polo match by stealing her headband:
Yuuka: (doing commentary) "...and just like that, Himegami is out. Kengo took her from behind like a thief in the night."
- Alas, Poor Villain: Gouken bordered on being more of a Punch Clock Villain and was eventually revealed to be one of Takeru Yamato's clones, when he possessed him. None of which mattered to Takeru, who beat Gouken to death, after Himegami sacrificed herself to save him. In the end, Gouken was as much a victim as she was.
- Awesome Art: Takeda Hiromitsu's character designs and backgrounds are reason enough to pick up the manga. But from chapter 23 onwards, the art improves considerably.
- Big Lipped Alligator Moment: At the start of chapter 16, Ms. Aki gets Kai to the nurse's office to treat his injuries but decided to change into nylons with gater belts and a thong first, then mounts him in the 69 position. Kai is understandably confused and asks why she's doing it that way, but she ignores him and proceeds anyway. It's the only time she's ever used such a risqué method and no explanation is given for it.
- Ensemble Darkhorse: Aki is popular with the fans for two BIG reasons.
- Hollywood Homely: By all outward appearances, Minori is still young and in better shape than Aki. Yet, the guys at Tenbi treat her as if she's a hag.
- Idiot Plot: The premise for episode 5 (season 2). Instead of saying she was dating one of the other teachers, Aki tells her parents she's dating a student, who's nearly half her age. Her parents simply take her story at face value and kidnaps a minor, then strands him on an island with their daughter in hopes that he'll knock her up. Which ends with him taking a beating for a situation that wasn't his fault, because Aki chose not to say anything.
- Les Yay: Some of the promotional art features the female cast in suggestive positions with each other. There's one between Himegami and Haruko and another featuring Takaki with Love Espada.
- Magnificent Bitch: Otohime may be a coward, but she's smart enough to learn from past mistakes, so the same tactics can't be used against her twice. During the Okino Island arc, Takeru's "Drive Duo" was able to nullify the Black Element she used to mind control the islanders. So Otohime devised an alternate form of mind control that doesn't use Black Element, rendering Takeru's Maken ability useless. And the first ones she used it on were the Four Pillars of Tenbi, which includes Love Espada. Thereby turning her enemies' strongest group of ability users into her own elite squad.
- You mean the cute plucky comic relief character, who likes sweets and happens to look like Makoto Nanaya? Yeah, Inaho, all the way.
- Oh, and Celia's sure to draw out reader's big brother instinct, since she hasn't got a chance of hooking up with Takeru, because his heart's set on Haruko. Even less so, now that he knows she's really a guy. Break out the hugs.
- Nightmare Fuel: Ask yourself which is worse:
- During the scene where Takeru Yamato first takes possession of Gouken's body, his eyes change from white to black and he moves like marionette - complete with one of the most unsettling grins ever.
- Or the scene in chapter 57, where Takeru becomes so enraged that he beats Gouken to death; not caring that he was possessed, or that the act was futile. All played horrifically straight.
- They Wasted a Perfectly Good Character: Gouken was criminally under used, until the midway into Okino Island chapters (42-49), where he was revealed to be an S rank ability user. Any potential he may have had went out the window when Takeru beat him to death, in a futile attempt to kill Takeru Yamato.
- They Wasted a Perfectly Good Plot: The anime's first season only covers chapters 1-10, then skips to chapters 26 and 27, while the OVAs loosely cover chapters 28-30. The rest is filler. Meaning, you'll be missing the majority of the manga's most significant plot details and developments.
- What an Idiot: During the Himekagura Festival, Otohime challenged Maken-ki to a contest for possession of the original 8 Maken. So how did Minori decide which members would participate...? With a game of rock-paper-scissors. Predictably, they lost.
Himegami: (angrily) "Why am I not included in the bunch? How could you even make a decision with 'rock-paper-scissors' for such an important battle?"
