Grim Grimoire is a real-time strategy game brought to you by Vanillaware and Nippon Ichi.It tells the tale of a magically-gifted child called Lillet Blan, who gains admission to a renowned Wizarding School called the Tower of Silver Star. There she meets an eclectic ensemble of students and teachers- the mysterious and bearded old headmaster, the sarcastic and Obviously Evil Sorcery teacher, and the cold but perceptive honour student, to name a few- and learns about the four schools of Glamour, Necromancy, Sorcery and Alchemy.Everything is going swimmingly until the fifth day, when Lillet awakens to find that everyone is dead and that a sinister evil has been unleashed from within the school. Lillet is soon killed as well, but suddenly finds herself in a Groundhog Day Loop, thrust back to her very first day in school but retaining all the knowledge she learned in the meantime.After taking the sensible approach of alerting her teachers, only for it to result in spectacular failure, Lillet realizes that her only chance of averting her fate and escaping the time loop is to do it all herself. Along the way, she'll delve into the history of the school and discover dark secrets about practically every member of the facility, including herself.Grim Grimoire wears its inspirations on its sleeve, and none the worse for it. Though the plot has been described as weak, the characters more than make up for it, with a whole school full of freaks and lunatics barely capable of organizing their own twisted love lives, let alone a workable school.This might explain why they're all totally useless.
Beast and Beauty: Subverted, in that the Beast does not love Beauty (even though this would break the spell), is somewhat of a nerd, and doesn't care what he looks like.
Only in the localization. Gammel Dore just had a name change to appeal to the Harry Potter fans in America. Advocat may be a snarker, but he and Snape are on two completely different levels.
The Computer Is a Cheating Bastard: They aren't restricted by silly things such as resource levels or build times—in fact, you can even catch the computer in the act of teleporting in more Mooks for it to use.
Crippling Over Specialisation: Affects the Skullmage, who's role as chief killer of ethereal units is easily taken by other more versatile creatures.
Devil in Plain Sight: Done literally with Advocat, subverted in that he's not one of the villains.
Deal with the Devil: Literally, many times. Hell is going to have to update its rules to avoid falling for Lillet's last deal.
Unless Hell is run by individuals like Advocat; in that case, they'll have a field day at every poor schmuck demon that actually falls for the trick.
Speaking of Advocat; his deal with Gammel is that he will "teach and assist" at the school for no pay; but should Gammel ask for a Deal with the Devil for his soul; he'll get it. Gammel never succumbed, even in timelines where he's about to be possessed by Grimlet.
Did You Just Scam Cthulhu?: Lillet successfully pulls this off in the end with Grimlet, making contract with him where her request is for him to embrace god, which devils can't do, and since neither of them can change he contract, he gets sent back to hell for breaking it.
Dub Name Change: Gammel Drask (an alcoholic beverage in keeping with the themed names) became Gammel Dore (which should be obvious), and Margarita Frozen became Margarita Surprise.
Foreshadowing: On the fourth Day 1, Advocat, while listing things that a high level demon could do for a contract, he mentions praying in a church as something they couldn't do.
Full Name Basis: Advocat just...tastes Lillet Blan's full name every time he says it.
Getting Crap Past the Radar: When Lillet first meets Advocat he starts harassing Amoretta, all the while making quite a few sexual remarks that you wouldn't believe made it into an E10+ game. It gets worse when you notice that before the comments start, Amoretta calls Advocat her uncle. There's also another time where Lujei, when speaking to the skull of her dead lover, tells the skull to 'tell me again what you whispered to me in bed.' Um.
The Gods Must Be Lazy: There's no other explanation as to why devils can walk around as they please and have to leave humans to stop them.
Groundhog Day Loop: Lillet seems to be cursed into repeating the same five days over and over again until she gets it right.
Heroic Sacrifice: Made by several characters over the course of the game. Lillet's ultimate goal is to find a way to win without anyone having to do this.
Hide Your Lesbians: Technically, Lillet and Amoretta don't do anything like kissing; but they do live together in the end. Snuggling in bed together is compared to one being "like a baby." Declarations of love can still be argued to be "sisterly." They never cross that ever so fine line of plausible deniability on the part of the writers.
Instant-Win Condition: Destroying enemy runes is the generic win condition, but you can also force an early win in the Hold the Line mission(s).
It's Up to You: Of course it is. You're the protagonist! (Hilariously, in subsequent loops, Lillet will blow off helping certain people because she's got bigger priorities.)
Justified Tutorial: Lillet's a new student, and it's her first day of school. Of course, on repeat sessions everyone expresses considerable surprise at how much Lillet already knows.
Karmic Death: All the bad guys, thanks to some particular cleverness on the part of Lillet.
Lightning Bruiser: Chimeras are massively destructive (and can actually out damage dragons since they have a higher attack rate) and move alarmingly fast, and ignore obstacles, but their HP gradually decreases. Also, while the game lists them as having close to the same HP as dragon, their defense is nowhere nearly as high so they die much more easily.
Meaningful Name: You cannot help but suspect Margarita Surprise from the beginning.
It's less obvious in the Japanese version, where her last name is 'Frozen'.
Mighty Glacier: Dragons. By far the slowest units in the game- but by FAR the strongest (most units die in one or two attacks, unless they're astrals, but using skull mage using astalize on the dragon can solve this) and by far the most durable. It's attacks. They. It takes an ARMY to bring down even one. Or a well placed sleep spell from a Grimalkin.
Necromancer: Opalneria. Also Lujei when she was alive. Also, Hiram is Opalneria's student which makes him an apprentice necromancer.
Older than They Look: Opalnaria. Gets even worse when she changes her appearance to a schoolgirl's to make things more "suitable" for her Hot for Student role.
Smug Snake: Advocat, another rare protagonist example. He is a devil who could be a Magnificent Bastard if he wanted to, but he knows he has very little to gain personally from the conflict.
Spanner in the Works: Nobody, not even the highest ranked Demon or the Archmage, counted on one humble transfer student blowing all of their plans to hell.
Crossover Example: Lujei Piche ends up sending the demon Sulfur, villain of Phantom Brave back to his world despite the sacrifices involved in banishing him, as revealed in her Cameo in Soul Nomad & the World Eaters.
Stealth Pun: The sorcery teacher is a devil. His name is Mr. Advocat. And he's constantly flip-flopping his allegiance based on his mood. Put the pieces together. He's a devil's advocate.
Summon Bigger Fish: The only way to defeat Calvaros is to summon the arch-devil Grimlet, who takes his soul to hell. Of course, then you have to deal with Grimlet which is where things get difficult.
Theme Naming: With three exceptions, every character is, for no apparent reason, named after an alcoholic beverage. Two in the Japanese version (Gammel Dore is Gammel Drask in Japan.)
Tome of Eldritch Lore: Lillet keeps getting more powerful versions of these, and they stay with her each reset.
Tsundere: Opalneria has been described as... passionate.
Wishplosion. An incredibly epic one. Lillet summons a massively powerful devil, which fulfils the Big Bad's contract with him, which gets rid of said Big Bad - and then Lillet drops a Logic Bomb on the demon, making a contract and then wishing for it to embrace God. The demon refuses and therefore suffers the consequences.
Zerg Rush - On the first couple of days, you can just mass-manufacture your unit of choice and march them to the objective. Not so much on the later days, where your opponents tend to have a mix of unit types. Phantom swarms, for instance, go from awesome (when the AI tends to have little to counter them) to short-lived (when the AI gains Homunculi and alchemy area-of-effect attacks) to awesome again (when you figure out the subtle nuances of using other units to take out said Homunculi and area-of-effect defenses before sending in the crazy sword-swinging avenging ghosts soldiers).
