* EvilIsSexy: Stella is an ElegantGothicLolita whose dress sports Absolute Cleavage that bares her head-sized breasts. [[spoiler:And she turns out to be a subversion, as she still wears that even when she's good]].
* GameBreaker: Sisters mode is incredibly easy for two reasons: the sisters float and hover in the air (at the cost of MP), and their method of attack is entirely done by the touchscreen. Stella does physical attacks by rubbing the stylus over, while Loretta launches a barrage of ice magic where the stylus is placed. With Loretta, even ice-resistant enemies fall in seconds (save for mage-type enemies). Attacking also consumes MP, but on the ground they recover it quickly. They're also immune to all status ailments. Of course, you have to beat the game just to unlock the mode to play as the sisters first, so there's not much of the game left to break.
** Charlotte can learn a spell called Ice Needles that is bought early on in the game. Because of its fast cast rate, multiple "needles", low mana cost, and [[DiscOneNuke high damage]], it's incredibly useful for taking out rooms of enemies with ease, even late into the game. Later in the game, Chain Lightning can be gained, doing huge damage to every enemy onscreen when fully charged.
** Similar to the Charlotte example above, Jonathan can buy the Shuriken subweapon really early in the game, and you'll almost never need another one. It's easy to master, and when mastered it basically obliterates anything in front of or below you.
** The fully powered Vampire Killer, while not the strongest weapon by any stretch, is ridiculously good due to the typical speed and range of the whip combined with a high enough attack power and holy/flame elemental , especially when the special attack is used. This does huge damage to many enemies. Other stronger weapons are often much slower and their specials aren't as good.
** The Cross subweapon, which can be obtained from a quest unlocked somewhere between halfway and two-thirds through the game, is flat out ridiculous. It does solid damage, penetrates enemies, can score multiple hits against pretty much anything with good aim, can strike enemies behind you as well if you jump out of the way when it comes back, and has an elemental advantage over virtually every creature in the game. It doesn't cost all too much MP, has good reach and an easily predictable flight pattern, and becomes downright HUGE when mastered, which also lets you throw two of them. In other words, it's pretty much a Boomerang, Bible, and Shuriken compressed into one highly potent package. Not only does it make clearing rooms a snap, but it also flattens all but a couple of bosses (most of which show up BEFORE you can obtain it), but it also makes the optional level restriction runs incredibly easy.
** Miser Ring (increase power realitve to your gold stash) + Gold Ring (increases the amount of money you can earn from candles realitive to gold stash) + [[ThrowingYourSwordAlwaysWorks Heaven's Sword (a weak, but long range sword Jonathan can swing real fast and can easily hit an enemy multiple times in one throw)]] or Holy Claymore (ridiculously powerful sword with slash and holy attribute)= [[CurbStompBattle Total Annhilation.]]
** The Sage Ring boosts mana regeneration; when you have two and Charlotte's Healing spell, you have FREE healing (if you are paitent.) A similar thing happens if you equip healing mail and [[GoodBadBug walk against a wall.]]
* FridgeHorror / TearJerker: The Circus of Fear. [[spoiler:It's mentioned that Brauner lost his daughters because of the first World War. The painting (and by extension, the stage) shows the aftermath of a circus and town torn apart by war. Put two and two together. Worse, as you go further into the level, the stage gets turned on its side, and then upside down, representing how Brauner's life was literally turned upside down. And then there's the boss...]]
* GoodBadBugs: You can duplicate quest rewards for [[DiscOneNuke early access]] to the Holy Claymore. You can also glitch the vampire sisters with a deft usage of Clear Skies, freezing them in place for the entire remainder of the battle.
* HellIsThatNoise: You will likely come to dread "SISTER!" "Ready, sister, I shall KILL YOU!", since it heralds Stella and Loretta's CombinationAttack.
* HilariousInHindsight: The main pair make an impressive team. Jonathan is the truly talented one, with the training necessary to accomplish his goal, but he suffers from deep self-esteem issues. The younger 16-year-old Charlotte accompanies him with her own (even if considered lesser) talents and much-needed moral support, allowing him to reach his full potential. Cue the sixth season of ''Series/BritainsGotTalent'' and the second-place team of opera singers Jonathan and Charlotte, who have the ''exact same team dynamic''.
** Creator/TakahiroSakurai's role as [[VampireHunter Jonathan Morris]] is even more hilarious if you know he voiced [[{{Literature/Twilight}} Edward Cullen]] in Japanese, the same kind of monster Jonathan is ''hellbent to destroy''.
* MemeticMutation: JONATHAN! CHARLOTTE! JONATHAN! CHARLOTTE!
** (SCREAMS) and (SOBS), the game's very articulate way of expressing inarticulate vocalizations.
** The description of Death in the manual. "{{Lawful evil}}. [[BattleButler Has some samurai-like aspects]]."
* NightmareFuel: The Legion - heavily subverted thank to the overly bright atmosphere of the boss music...
** In one of the miniquests, you have to get a tear located near a certain statue. When you take it... *Shudder*
* TheScrappy: Vincent's [[NoHeroDiscount refusal to lower his prices]] (even after being cured of vampirism) has gained him some scrappy status. He's still far more likable than the inheritor of his name in ''VideoGame/CastlevaniaLordsOfShadow', though.
* ThatOneAttack: Stella and Loretta can do a CombinationAttack in which Loretta makes a {{BFS}} out of ice, and Stella smashes it on the players, most likely resulting in a OneHitKill.
* ThatOneBoss: FrankensteinsMonster isn't actually too hard, with [[MightyGlacier hard-hitting but easily telegraphed attacks.]] It's when you meet [[WolfpackBoss two of him]] in the Nest of Evil that fit hits the shan. You can't reliably predict what one of them will do because the other is off screen or surrounding you, about to sucker punch you. Abusing the NotCompletelyUseless Clear Skies spell is almost mandatory here. The worst part? This is the FIRST room of this floor. The boss at the end of the floor? [[VideoGame/CastlevaniaChroniclesOfSorrow Abaddon.]]
** You ''can'' just try to survive against the Creatures for sixty seconds, at which point the door to the next room will open whether they're beaten or not. Not that this is much easier, mind.
** And you can forget trying to beat these two if you're playing with any of the alternate characters.
** The [[spoiler:purification of Stella and Loretta, where casting Sanctuary takes 15 seconds and Charlotte cannot get hit during it or it fails, nor can she go offscreen, and if either character gets hit, that's like a 3KO, and it's even worse on Hard mode. Trying to do this at low levels can make it pretty much a LuckBasedMission. [[NoSell Stonewall]] is your friend here.]]
*** Worse? [[spoiler:Sanctuary has a range of one screen-width with Charlotte as the center. Since you'll be playing as Jonathan keeping the sisters to one side so Charlotte doesn't get hit, it's possible for the spell to ''miss''.]]
*** One saving grace is that [[spoiler:you only need to hit one of the sisters with it for it to work.]]
** Death can also have shades of this, being Death and all.
* TheyWastedAPerfectlyGoodPlot: [[spoiler:Brauner believes Stella and Loretta are his daughters reincarnated, but this is never explored and we don't get any confirmation for one way or the other.]]
** [[spoiler:Of course, it might've just been put in to show how insane he is.]]
** There's an Axe Armor mode but no John Morris/Eric Lecarde mode, despite this game being a sequel to [[VideoGame/CastlevaniaBloodlines theirs.]] And/or even a ''VideoGame/CastlevaniaIIIDraculasCurse'' mode, since the sprites for the player characters in that game (except for Alucard) are in this game but used for bosses (recycled from ''[[VideoGame/CastlevaniaSymphonyOfTheNight Symphony of the Night]]'').
** The UsefulNotes/WorldWarTwo setting isn't used to its full potential. Like, there are no Nazis dabbling in [[{{Ghostapo}} the supernatural]] or with [[StupidJetpackHitler super-science]], or [[{{Magitek}} both]].
* WhatAnIdiot: [[spoiler:Dracula has a WINDOW in his throne room. He's a vampire. Sunlight is bad for him. Sunlight coming in through this window is the cause for his death after his defeat.]]
