These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Regarding Iris. Seeing that Spiritia is the other incarnation of Rosenkreuz as Iris is, does she want to kill Spiritia because "there can only be one god" or because she wanted to steal Spiritia's inner powers and become "whole"?
And then we have more themes added for Freudenstachel that sound EVEN MORE AWESOME.
Best Boss Ever: Karl Palesch, who only appears in Pamela's side game in Freudenstachel, taking Pamela's place in her own stage.
Breather Boss: Surprisingly, Count Michael Zeppelin, the boss of the first fortress stage in Freudenstachel is nowhere near as hard as the stage it appears in. Although it isn't an actual weakness per se, the Frostklinge, obtained from Dolis, is very useful against it, able to damage it without the need for standing on the platforms on the sides, and its attacks are very easy to avoid when you learn how. And if you use its actualweakness...
Complete Monster: Iris stands alone as the worst of the enemy lot. She commited some very heinous acts, many of which are for her own twisted amusement. These actions include starting a war and killing off family members that aren't useful for her. She even chooses victims based on who would suffer most from their deaths. When confronted with the fact that her desire for atrocity would keep her from being able to control her power, she simply shrugs and feels that she's right to simply destroy whatever she wants.
However, in Kiora's doujinshi Rosenkreuzstilette AfterStory, otherwise known as Tearis, she gets reduced from a Complete Monster to a Jerkass Woobie who is placed under the care of Spiritia, who believes that killing her won't solve any of the problems she left behind, and thinks she has a kinder, gentler side inside her. Of course, Zorne still blames Iris for her adoptive father's death and vows to kill her, leaving Freudia to attempt to stop her through battle (which gives way to Zorne's new rage-born power), and Iris, knowing of the conflict, asks Spiritia to end her life in order to truly end the ensuing chaos.
Demonic Spiders: The bouncing gargoyles that are usually found near the end of a stage. They have a ton of health and can do some serious damage to your character. To be fair, they were inspired by the bouncing spring robots found in several Mega Man games.
Evil Is Cool: While not really evil, Count Michael Zeppelin definitely looks stylish.
Fanon: Along with what has already been denoted as such, there are fanonbiographies of the (human) characters of the first game (mostly by trolls), which list everyone as being all born before Y2K. At least it explains their clothing....
Game Breaker: In the first game, since Luste Teuber is Metal Man's expy, Spiritia in turn gets Metal Blade in the form of Lustatem. Like Metal Blade, Lustatem has a TON of energy (second to the Freudenstachel), normal shots does more damage than an uncharged Seelegewehr, and Spiritia's notdenied of a diagonal attack.
Another for Spiritia is the Grollschwert. Sure it sucks at first and doesn't do much in the way of damage, but remember, it is the Grollschwert. The weaker you become, the stronger it gets! So once you're at a pitiful amount of HP, the short-ranged normal shots becomes a mid-ranged Spread Shot that can tear apart most of the enemies with ease and can break some of their guard. It even slaughters the Demonic Spiders above and Goddamned Bats below with little effort.
Goddamned Bats: The barrels in Sichte's Freudenstachel stage. You know, the flying ones with eyes that extend their antennae and shoot electric beams from the spikes on their tips. Yeah, they're goddamn annoying.
Also, the enemies that resemble Mega Man's Mettaurs. And the spear-throwing knights. And the cross enemies. And the egg-dropping eagles. And the skulls that are invulnerable except against some special weapons. And the fireballs that resemble a certain powerup from Bomberman. To be fair, pretty much almost every regular enemy that RKS has to offer.
Les Yay: There's quite a bit of subtext between Zorne and Trauare. Aside from this image◊, when you fight one of them, they'll be quite angry if you've already beaten the other. Additionally, in Freudenstachel, when you fight one of them, if the other hasn't been beaten yet, they'll join in with a combo attack, which wouldn't normally carry much subtext, but Trauare's combo attack with Zorne being heart shaped bombs definitely does.
There was already some subtext with Spiritia/Freudia in the first game, but the second only increases it. Freudia will apologize to Spiritia when she dies, she goes Tranquil Fury when she finds out what the Big Bad has done with her and the Game Over screen for the final stage resembles a certain Ho Yay scene from Mega Man X6.
"Pitting the peaceful Liebea against your idiotic ideals was sheer brilliance! Turning friends on one another thanks to a tiny seed of doubt I planted... wonderful! Even the stoic Sichte swallowed that drivel about a world just for Magi. Hook, line, and sinker, no less! Magnificent! And witnessing the dreams of the commonfolk being trampled underfoot... Hahaha! I think I'm going to cry!" ♪
Her Dragon Eifer, too. The fact that she and Iris manipulated the Schwarzkreuz into attacking both RKS and the Empire and kidnapping Spiritia to have her all Brainwashed and Crazy places her into Magnificent Bitchery as well, even if she was just another pawn of Iris. Of course, she tends to constantly alternate between this and a Smug Snake as well, and the reason is obvious.
And yes, even Iris can be seen as this. True, she may be a despicable monster, but seriously, you have to admit she's cute even when she feigns helplessness.
Moral Event Horizon: Iris did this entire gambit to accomplish her ultimate goal, but, she says she also did it for personal amusement. She's murdered her father, jailed somebody who knew about her plans, and, in Grollschwert, kills a priest just for fun, that shows that Iris crosses the line. She tops all that in Freudenstachel, where she mind controls Spiritia and forces her to fight Freudia to the death.
Most Wonderful Sound: Strudel saying "Rosenkreuzstilette" sometimes (it's usually Freudia) when you start Freudenstachel is simply adorable.
Liebea counts as a Woobie as well. She was trapped at the top of the research tower for her refusal to take part in the rebellion. Count Zeppelin did this to her to avoid her becoming an obstacle and, out of fear that she'd become his adversary if he told her the truth, he lied to her that the Empire had taken Karl captive and said that there was no hope to pray for his safe return. And when someone points out his/her disbelief that the Empire should do anything to him or that he/she knows whether he's dead or alive, Liebea just gets upset and her power goes out of control until that someone calms her down through battle.
Sichte may count as a Woobie as well since she has trouble having faith in anyone older than her due to often fretting about her troubled childhood that she had when she was born and raised in the slums.
Spiritia. Think about it for a second. You see a girl you held dear being taken away from you and you try to save her, then you find out all of your friends are in a rebellion and you are forced to fight against all of them, unable to convince them out of it without fighting, and in the end, you find out the girl you were trying to save is actually a Complete Monster of the highest order who set the events into motion only For the Evulz, you're forced to fight against her, and a while after that, you end up mind-controlled by said girl, forced to fight your best friend. Wow.
Lilli. It's really easy to want to give her a hug considering her home was burned down. If Spiritia wasn't around...
