Disgaea 3 is set in Evil Academy, a school for demons that celebrates troublemakers and people who ditch class as honour students and labels diligent and polite demons as delinquents. It's a funny little backwords logic world that fits right at home in the wacky Disgaea universe, but how such a world could possibly function was beyond me. I dismissed it as Rule of Funny until a random NPC commented on how nobody ever passed the end of semester exams. Since everyone always failed, everyone always had to repeat the year. So what about their tuition fee??? Suddenly it made sense! The Academy encourages students to slack off and not work so they can never leave the school (or even want to leave), thus making them pay tuition for eternity.
Wouldn't they just get sent to other schools? Why would they ever be sent there in the first place?
So demon parents can get the brats out of their hair for a few centuries. You know, just like the real world.
That's the thing. There isn't any other school- the entire Netherworld is the Academy!
In fact, one of the creatable characters in the game, the male healer, reffered to as Clergy, does mention this in class if you talk to him a few times.
Clergy: Being an Honor Student meaning flunking, which means you have to keep paying tuition forever...
Speaking of Disgaea, let's talk about the angels. Two major characters, Flonne and Lamington, in particular. Many people probably know Lamington is the name of a volcano. But I recently discovered that it's also the name of a sponge cake from Australia. Suddenly, Flonne's name made sense: It's supposed to be "Flan"! Whereas the demons have their volcano Theme Naming, the angels are instead named after desserts (except Vulcanus, but that's because he acts more like a demon than most actual demons in the game do) and the name Lamington is just a huge pun on both! It may also explain his Sweet Tooth in the manga, as well.
The thing is that her name sounds like "Flan" only in English. In Japanese, it's sounds more like "Flown" (Furon).
In games 2 and 3, there are 'Cell Phone' items with various functions - one of which is 'Call Zenisky Financial Services'. This either grants you some free cash, or steals a chunk of it away. The brilliance is actually in the name, a joke lost in translation. In the original, 'Zenisky' would be spelled 'Zenisuki'...Zeni (One reading for the Japanese kanji for 'money') + Suki (the verb, 'to like') In other words, the name of the financial company is, "I like money"!
Extra brilliance when you figure out who's running the business in the first place. It's Hoggmeiser from Hour of Darkness, whose Japanese name is Zenisuki.
Here's one thats easy to miss. Remember the Prism Rangers? It might seem like a withering deconstruction of Super Sentai. But as of the revelations off Z.H.P it actually becomes obvious why they're so weak. Their HEARTS aren't set on the passion for Justice and Love that MAKES a Hero's powers work! In the first game their only in it to make friends. In the SECOND game they actually target a bad guy...but willingly consider attacking women and children who may or may not be evil demons. Aside from that, they regularly demonstrate a cowardice that not even the Main Character of Z.H.P ever shows, DESPITE him being a literal Heroic Bystander who may have had The Call forced on him.
Here's a Fridge Brilliance to the Fridge Brilliance: Disgaea Infinite explains that the Prism Rangers are also part of a Show Within a Show that's shot live and that characters have a very good chance of dying. In the case of that happening, the producers start looking for replacements, either through scouting or kidnapping. So it makes sense why their hearts aren't in the right place for the hero powers to work — They were forced to do it.
Consider Krichevskoy for a moment. Ever notice how, if you gave him a shave and a haircut, he'd look a lot like Vyers?
Fenrich's Ho Yay behaviour towards Valvatorez and his hatred for Artina takes on a different meaning to those who understand canine psychology. Canines can be quite clingy and jealous when it comes to their master. As such, they tend to hate any potential new mates master might take up, seeing him/her as an infringment on its territory. Fenrich also happens to be a canine like creature himself.
The opening song to the second game, Sinful Rose. After much confusion over what the song was talking about, it hit this troper: It's from the true Overlord Zenon's POV. Switching between being about herself and her thoughts on everyone else (people being lying, corrupt bastards).
At first, it may seem like Flonne took in Artina when she became an angel out of pity but if you think about the circumstances surrounding Artina's final days as a human, it's actually much more than that. You have Artina, a citizen of a country opposing another country, yet she takes care of the sick and injured regardless of alignment. She also meets a demon who she takes pity on, which the demon find strange. Eventually, her country labels her a traitor and has her executed. The demon she met is looking to avenge her, but she doesn't want that and he decides not to go through with it despite his anger towards her executioners. Now play the final episode of Disgaea: Hour of Darkness. Suddenly, Flonne and Artina are Not So Different.
Valvatorez manages to shrug off the effects of the A-Virus, apparently due to Heroic Willpower, though he of course attributes it to sardines. Very in character for him, as he attributes all his power to sardines. But think about the little speech he gave on their benefits in the opening scene; he mentions how good they are at purifying the blood of toxins, due to the presence of omega 3 fatty acids. And how it's Artina's angelic blood, which removes all impurities, that acts as a cure. With that in mind, it's just possible he was right this time, and his immunity to the virus does have something to do with his sardine consumption.
So why after pledging their allegiance to Laharl does Laharl make the Krichevskoy Group Etna's vassals instead of his. It's their punishment for trying to rebel against him and putting him through everything throughout the game. First, making them Etna's vassals puts them in a very low position amongst those working for him while still allowing him to make use of their skills. It essentially puts them on the level of the Prinnies. Second, Etna has always been known for not being very nice to her vassals...
So in The Stinger of Dimension 2. Etna meets someone implied to be Xenolith and tells him that she'll get him pardoned in exchange for him having to serve her. How and why is this the case? Simple, By that point in the game he'd A. Committed two huge sins of kidnapping angels andalmost destroying the Netherworld and B. Got sucked into the Netherworld itself at the end of the game, being buried alive tends to be unsurvivable. What happens to dead souls who committed sins in this series? They become Prinnies!
Seeing as how Disgaea D2 takes place -before- Disgaea 2 and Disgaea Infinite, it's possible it also fits in before Prinny: Can I Really Be The Hero? - It is entirely possible that Xenolith is the titular Hero Prinny working to pay off his sins under his new Master Etna. It would explain why he's singled out.
The subtitles for each game are subtle hints regarding the main plot twists, and, to an extent, the final bosses of each game.
Hour of Darkness: This one is probably pushing it, but messing around with the title a bit can give you Darkest Hour, possibly regarding Laharl going berserk on Lamington for turning Flonne into a flower.
Cursed Memories: Overlord Zenon reincarnated herself to escape her old life, rendering that life nothing but memories. The cursed part comes in when Fake Zenon's plan involves getting revenge on Zenon rather than Rozalin
Absence of Justice: Turns out Super Hero Aurum fights for glory, not for good, and does whatever he can to obtain that glory.
A Promise Unforgotten: This one involves Valvatorez's promise to Artina, which is pretty obvious, but not so obvious is the fact that Valvatorez makes a lot of promises to the party throughout the game, and did his damndest to preserve them during the final four chapters, and ultimately made the promise to help Nemo pay for what he did, even if it took him a few thousand years.
A Brighter Darkness: The bright angels are being used to stabilise the dark netherworld. To an extent, it also references the fact that Xenolith is a grey villain instead of a white or black one.
In Disgaea: Hour of Darkness, the full fledged angels fought as enemies appear outright emotionless, acting almost like robots. One wonders if the game's events didn't happen, if Flonne could have ended up like that.
To add to this, when they return in later games under new Archangels (Archangel Virunga in Disgaea Dimension 2 and Archangel Flonne in Disgaea 3), the angels are nowhere near as emotionless as they were under Vulcanus. What exactly was Vulcanus doing to the angels to get them that cold and emotionless?
It's not just Flonne. Sicily and Artina would have also became as emotionless as the D1 angels had Vulcanus's reign of terror has lasted longer than it had.
Speaking of Sicily, What would happen if Vulcanus knew that that she was half demon? This being Vulcanus, the answer would notbepretty
