History Manga / VermeilInGold

* MayflyDecemberRomance: Alto is 15 or 16 at the start, while Vermeil is a demoness who is at least 550 years old.

* DidTheyOrDidntThey: [[spoiler:Once Vermeil and Alto express their feelings for each other, their make out sessions become ''much'' more passionate, with the two clearly clinging to each other in bed that would make it look like they had sex. There is no evidence that suggests they have, but it the way they are shown makes it difficult to see if they did or not.]]

* AbsurdlyPowerfulStudentCouncil: The student council is made up of five of the most powerful students in the academy and Lilia says they have a great amount of influence in how the academy is run. It's rumored even the teachers ultimately have no authority over them. Somewhat {{Justified}} by the sheer level of power on the council, with five Gold rank mages (one of them being a potential Platinum rank). [[spoiler:Plus Alto, who while not yet ranked when he joins, with Vermeil, he has Gold/Platinum potential.]] This makes the council stronger than most of the teachers.

* MagicKnight: Most mages in the setting seem to adopt this style of fighting, using their magic to augment their bodies and/or their weapons, or at least being fit enough to not be helpless in melee range. Even Alto, who relies mostly on projectile attacks, learns to summon a magical sword after some training with the Student Council.

* TheMagocracy: The country the characters inhabit is entirely governed by mages.

* {{Ecchi}}: Very much so. While the series is actually more chaste than some other ecchi stories from a visual standpoint, making heavy use of SceneryCensor and BarbieDollAnatomy to hide naughty bits, the humor is still incredibly raunchy. A good example of this is [[ReluctantFanserviceGirl Lilia]], who has [[ForcedOrgasm endured]] [[TheImmodestOrgasm two]] unexpected [[TheModestOrgasm orgasms]] and twice has to [[InvisibleStreaker strip to use her invisibility potions]]. And then there's Vermeil... In short, she is a proud MissFanservice who routinely has a ton of skinship with Alto that ranges from comically erotic to intensely intimate (and erotic). Not to mention how frequently and intensely she kisses him.

An anime adaptation began airing on July 5, 2022.

* SelfFulfillingProphecy: [[spoiler:The people from Vermeil's hometown blamed her for a plague, and decided to kill her in the belief it would stop the deaths - only for their actions to cause Vermeil to awaken her demonic powers and obliterate the entire city. Fatema lampshades this, stating that Vermeil’s destructive powers caused a lot more casualties than a plague could ever do.]]

At a WizardingSchool called the Ortigia Royal Academy of Magic, Alto Goldfield must summon a {{Familiar}} or else be held back a grade (as Familiars are necessary for much of the work going forward). Having failed to summon even one, he finds an old grimoire and tries the summoning spell inside. He ends up summoning a powerful, seductive devil named Vermeil who agrees to become his Familiar. He asks her to pretend to be human to not scare anybody, as she can conceal her horns and tail, but this causes them to come under scrutiny as humans have never been summoned as familiars before. The two must get through the school year amid several people picking fights and Alto's jealous childhood friend, Lilia Kudelfelt, while Alto seeks his dream of becoming a Platinum rank mage. Bigger, darker plots also soon are revealed to be taking place.

* TheBet: Lilia challenges Alto to a duel with their familiars. If she wins, Vermeil has to stay at the dorm unless she is needed, and if he wins, Lilia will have to get along with Vermeil. Alto and Vermeil win, and Lilia is very unhappy.

* GemstoneAssault: Alto's favored form of magic lets him summon and form crystals in creative ways.

** Another happens in episode 9 and 10, when it clears shows Iolite '''still in his normal, imposing robes no less''' and not in any normal academy uniform, and in episode 10 it shows Iolite literally napping during the written portion of the bronze exam. Alto really is that slow not to pick up on any of these obvious signs of someone that shouldn't even be there in the first place.
