The intro sets nearly every expectation for this series as a run-of-the-mill harem comedy with a little magic thrown in...which it is, as far as that goes. The real hook is that every person in the world has a set number of uses of magic that they're born with, be that a handful, to a few hundreds, or well beyond. Once a person uses their last magic, their body turns to ash and they die. Aoi Gakuen is a school which prides itself on the fact that the average number of uses of magic of its students ranges well into the tens of thousands. Meanwhile, Kazuki's grand total is... Eight. However, because of a coincidence of powerful mages in his family tree, each of his eight spells is more powerful than anything any other mage in the world is capable of.
So, Kazuki has three girls fighting over him, and his whole class mad at him, since no one can figure out any good reason why any of the (arguably) three most beautiful girls in the school are suddenly hanging all over him. Beyond that, he's such a happy-go-lucky fellow that he burns one of his eight uses of magic to save a girl's bentou (box lunch) from falling on the ground, and thinks nothing of doing it.
The supporting cast is arguably more humorous than the main characters most of the time, with the antics of the school doctor, Akai-sensei, particularly not to be missed.
For those in the US, the series can legally be watched at Crunchyroll.

- Barbie Doll Anatomy: Most noticeable in episode 9, when they visit the hot springs.
- Averted in episode 19 when you see nipples on Kuriko and Yamase.
- Battle Aura
- Childhood Friend Romance:
- This Unlucky type is debatable, as he splits himself into multiple persons after becoming human, and Kuriko mentions keeping 5 or 6 of them to herself while giving Yamase one, to which she's perfectly okay with.
- Depending on your POV, Yuna and Yamase are both Victorious since Kazuki being split up into clones means they could both have one to themselves. Yuna doesn't like the idea, but Yamase seems happy to have one of him.

- Particularly hilarious at the end of the series.
- Clothing Damage: In one episode, a summoned monster manages to claw through Kuriko's blouse and bra without scratching her skin.
- The Collector: Shino seems to be a bit too obsessed at trying to capture Kazuki as a ghost.
- Contrived Coincidence: In episode 9, Yuna, Rin, and Elizabeth are taking a taxi to the hot springs hotel where Kazuki and Kuriko are (to increase his spell count). Their vehicle dies in the middle of nowhere, and the driver says he can't get it fixed right away. They wonder what to do next. Cue their gaming teacher, who JUST happens to be driving that way (to pick up a game), and gives them a ride to where Kazuki is.

- Hand Behind Head
- Heroic Sacrifice: Kazuki sacrifices his last spell and subsequently his life to save Yuuna's.
- Idiot Hair: Yuuna.
- Jerkass: Pretty much the entirety of Class B with the exception of Kazuki and Yuuna. Note that two of Kazuki's precious eight uses of magic are the direct result of the careless antics of Class B.
- Kansai Regional Accent: An odd usage, for the two episodes of the class trip to Kyoto, the episode previews are in Kyoto-ben... which for some reason in the R1 English dub is rendered as a cliche US Deep Southern accent - complete with a "ya see" tag for each spoken line.

- Two-Teacher School
- Unskilled, but Strong: Kazuki's Superpowerful Genetics makes him the mage equivalent to a rocket launcher. That said, he's only able to use eight spells before he dies.
- Ur-Example: This series is the granddaddy of all Harem works that take place in a magical school of some sort. Basically every trope you see in those modern works originate from Maburaho in some fort or another; from the idea of the setting itself making its magic known to the public, to the protagonist being a self insert loser who secretly holds grand power, to several of the female leads being tried and true archetypes vying for the protagonist, it all began here.

- Wham Episode: Episode 12. Kazuki uses his last spell and turns to ash, although he "survives" as a ghost.
- Wizarding School: Pretty much the whole point of the school. Everyone there has a vast pool of magic aside from Kazuki. Subverted in that there's little, if any indication that magic is being taught.
- Writers Cannot Do Math: At the rate most of the students use spells, even the more powerful ones would be out of magic by their mid-20s.
- Zettai Ryouiki: Kuriko, as seen in this page's picture.
