----
!!''Black Rose King'' has examples of:
* AbsurdlySharpBlade: Saya and Diva's swords, of course.
* ActionGirl[=/=]DarkActionGirl: Saya and Diva.
* AlternateContinuity: Follows the series up to Saya and Diva's final showdown in the Metropolitan Opera House, then spins off from there.
* AnythingYouCanDoICanDoBetter: As a Chiropteran King, Alessandro is far more powerful than Saya and Diva combined, cannot be killed by their blood, and has no need to actually drink blood to survive.
* ArmorPiercingQuestion: [[spoiler: When a Red Shield member attempts to shoot Diva in revenge for his family, Saya insists that they need Diva to beat Alessandro and asks if his family would want him to put revenge before stopping a threat even worse than Diva.]]
* ArsonMurderAndJaywalking: Saya's assessment of Alessandro and his capabilities are that he's "arrogant, a showoff, a sexist pig… and strong enough to kill all of us with a pinky."
* BadassNormal: The humans of the Red Shield.
* BigBad: Alessandro Noirroi, a Chiropteran King bent on destroying Saya and Diva.
* BigDamnHeroes: [[spoiler: During their first battle with Alessandro, Haji arrives just in time to save Saya from being eaten alive by a mob of Chiropterans under Alessandro's control.]]
* BoomerangBigot: Alessandro openly expresses disgust for most other Chiropterans, believing that their species was tainted by Saya's and Diva's births because their father was a Chevalier rather than a King. He is particularly disgusted by Saya and Diva, hating Diva because she was enslaved by humans and had to be named by her sister, and being particularly disgusted by Saya because she chooses to integrate into humanity and protect it.
* BloodyMurder: Alessandro states that, while the blood of a King cannot kill a Queen, it still hurts them badly- [[spoiler: which he demonstrates by [[HoistByHisOwnPetard stabbing Diva in the shoulder with her own sword (laced with his blood, of course)]], [[SpitefulSpit spitting]] [[BloodFromTheMouth his own blood]] [[EyeScream right in Diva's eyes]], and finally ''cutting his own hand'' and using it to punch clean through Diva's gut.]]
* BulletCatch: [[spoiler:At one point, Alessandro deliberately catches a [[MoreDakka hailstorm of bullets]] in his teeth and then [[CatchAndReturn spitting them at Saya and Haji]].]]
* CurbStompBattle[=/=]NoHoldsBarredBeatdown: Alessandro makes his grand entrance by putting the smackdown on both Diva and Saya, leaving the former near-death.
* DarkIsNotEvil: Saya, though that goes without saying.
* DeadpanSnarker: Alessandro. Not only can he avoid Saya and Diva's attacks with ease, he even finds time to crack jokes while doing so.
* TheDeterminator: Alessandro will stop at ''nothing'' to destroy Saya and Diva, at one point swearing to take them and everything they've ever ''touched'' and burn and bury them in "the worst-smelling landfill possible."
* EnemyMine: Saya and Diva are forced to team up to fight Alessandro.
* EveryoneHasStandards: [[spoiler: Despite their hate-filled rivalry, Saya still feels pity for Diva when she's locked in a heavy duty container meant to hold Chiropterans.]]
* FantasticRacism:
** Alessandro has nothing but disgust for the humans and all non-Chiropteran life forms.
** [[spoiler: One Red Shield member attempts to shoot a helpless and restrained Diva, and then disgustedly tells Saya that she's no different from Diva and just as responsible for the deaths of his family as Diva is.]]
* FlashStep
* GoodThingYouCanHeal: Saya and Diva, naturally.
* HeManWomanHater[=/=]StrawMisogynist: Alessandro.
