Go To

Azure Keyblades is a series of fanfics written by Atlas Ultima and is a crossover between BlazBlue and Kingdom Hearts.

Taking place after the events of BlazBlue: Central Fiction, Ragna finds himself in a land known as the Realm of Darkness. There, he encounters a young Keyblade Master named Aqua. The duo come across many perils as they try to find an escape from this dark place. Together alongside a freed Terra, they will escape and find a way to defeat the forces of darkness.


Current fanfics in the series:

Azure Keyblades: Distored Dream (Takes place during Kingdom Hearts 0.2: Birth by Sleep - A Fragmentary Passage)

Azure Keyblades: Key of Light (Takes place during Kingdom Hearts)

Tropes applying to the series as a whole:

  • Adaptational Angst Upgrade: Inverted. Aqua escapes the Realm of Darkness much earlier and Terra is freed from Xehanort's control, so they don't have quiet the same level of trauma as they did in the games.
  • All-Powerful Bystander: There is this mysterious entity that is a Reality Warper, but aside from sending Ragna to the Realm of Darkness to help Aqua, he primarily just watches what happens from his world. It isn't until Chapter 8 of Key of Light that he does a bit of fighting, and even then, it's not really an important one.
  • Alternate Universe: Since these stories long predate Kingdom Hearts III, there are certain differences.
    • Terra manages to free himself from Xehanort's control and joins up with Ragna and Aqua in the Realm of Darkness, with the trio escaping far earlier than canon.

    • Word of God confirms that Aqua will not become one of Xehanort's vessels in this series.
    • Keyblades also work differently here. They are described as sentient weapons that choose their wielders based off the strength of his/her heart. The Keyblade can later gain abilities such as transforming and traveling across worlds with the wielder's training. It is also possible for a powerful heart to bear two Keyblades at once, but such instances are rare, especially as of late.
    • Alice is also not going to be one of the Princesses of Heart, as the author stated that the age doesn't match up to him and her lack of significance in later games doesn't exactly work well for the story.
  • Continuation: The story is a continuation of Ragna's journey after he wipes himself from existence in his own world.
  • Experienced Protagonist: Considering that Ragna is hot off the heels of Central Fiction and both Aqua and Terra went through both their Birth By Sleep stories and the Realm of Darkness, they all fit this trope.
  • Advertisement:
  • For Want of a Nail: The mysterious entity states that Ragna's existence being brought to Kingdom Hearts has completely altered the coarse of history.
  • Gameplay and Story Integration: Some aspects of the games game-play get mixed in with the story at times to help Hand Wave certain things.
    • The Battle Aura, which is a passive ability of magic, is used to explain why Kingdom Hearts operates on Bloodless Carnage.
    • Magic evolves overtime through experience, much like an actual RPG. It's also connected to the mind so that the wielder can still perform spells even while severely injured.
  • Our Mages Are Different: Magic in Kingdom Hearts and magic in BlazBlue aren't exactly the same. Besides being more frequent in Kingdom Hearts, it also bears more versatility while BlazBlue magic is more specialized.

Tropes for individual stories:

    Distorted Dream 
  • Brought Down to Badass: When Ragna has to fight replicant versions of Tager, Jin, and Hakumen, he noted afterward that he felt like his strength was reverted back to the same level it was back in Calamity Trigger. This resulted in him making more frequent use of his Blood Kain form than he normally would have. He regains his strength after defeating his doppelganger.
  • Cliffhanger: The story ends with Ragna, Aqua, and Terra escaping the Realm of Darkness and arriving on Destiny Island... just as it's being consumed by the Heartless, leading into the sequel.
  • Curb-Stomp Battle:
    • Terumi delivers one to Ragna, albeit in a dream sequence.
    • Ragna and Aqua casually defeat the Demon Tide. Ragna even comments on how underwhelming the fight was.
  • Dark Is Not Evil: Due to her struggles against Xehanort, the Unversed, and Vanitas, Aqua has trouble with this mindset. This leads her to briefly become hostile toward Ragna after the display of his dark abilities.
  • Good Cannot Comprehend Evil: A better title would be "Good cannot comprehend dark is not evil". Aqua at first, doesn't understand how dark abilities like Ragna's can be used for noble purposes or how he can use it without being evil himself. Thankfully, she starts growing out of this mindset across their venture.
  • Handicapped Badass: When Ragna arrives in the Realm of Darkness, he lacks the ability to use his right arm or eye as a result of the Grimoire being cut off from the Boundary. Due to his experiences during Chronophantasma, he can at the very least fight off Heartless without much trouble. Subverted after he kills a Heartless, where the Grimoire starts running off of Darkness instead of siether.
  • Power Creep, Power Seep: In-Universe. Ragna ends up having more trouble against Tager than he should have when he fought his illusion. During his fight with Jin, he noted that the illusion was when Jin was under Yukianesa's control and should have been easy to defeat, yet was able to fight evenly against him. This clues him in on the illusions weakening him back to his Calamity Trigger level. He also notes after his fight with Jin that the illusions' level of power is somewhat greater than when he first fought them in his world.
  • Shadow Archetype: Both Ragna and Aqua ended fighting dark illusions of themselves after they defeat Hakumen. Ragna's doppleganger mocks him for denying the power of the Azure, while Aqua's insults her for doubting herself and trying to keep the darkness at bay. Both even mock the duo for fighting against it instead of giving way to the darkness.
  • Spotlight-Stealing Squad: Downplayed. While Ragna is the main protagonist with Aqua as the deuteragonist, he ended up getting much more time and development than Aqua early on.
  • Where It All Began:
    • The mirrors in the Realm of Darkness cast an illusion that takes Ragna and Aqua to Kagutsuchi. There, Ragna ends up fighting through his Calamity Trigger story, while Aqua ends up fighting Hibiki and aiding Ragna against Hakumen.
    • After they fight Hakumen, they end up in the charred remains of the church where Ragna grew up. Here, they end up fighting illusions of themselves.
    Key of Light 
  • Armor-Piercing Question: When the group crash lands in Deep Jungle, Ragna questions Donald on why he tried to prevent Sora from exploring the world to find his friends, with Donald stammering that he didn't want to waste time and their mission is to find King Mickey. Ragna then questions him on if the King or if Sora's friends were in that world. The big one that gets to Donald is what if he was the one stuck there and Mickey did the same. Donald has no answer other than angry gibberish.
  • Angrish: Donald's response to Ragna's Armor-Piercing Question.
  • Animate Inanimate Object: All over the place in Wonderland, as to be expected.
  • Battle Aura: Merlin explains to Ragna and Sora that this is a passive ability of magic that anyone can use. Its main purpose is to protect the user from attacks.
  • Bloodless Carnage: Because magic users have Auras, they don't bleed when struck by lethal attacks. Of course, this can't last forever as there is a limit.
  • Brought Down to Badass: Terra and Aqua, due to having spent years trapped in the Realm of Darkness, aren't as strong as they were at the end of Birth By Sleep. They're still incredibly strong and experienced Keyblade wielders nonetheless.
  • Casual Interstellar Travel: The Gummi ship lets them fly to various worlds. It's also a necessity as Aqua and Terra no longer have their Keyblade armor.
  • Chekhov's Gun: The Mysterious Observer notices an unnatural transfer in a separate world and sets off to investigate. At first, the readers are left to speculate that he may have been referring to Sora's entrance of Traverse town, but since he doesn't ever appear before the group, that's clearly not the case. It's later revealed that the unnatural transfer was Naoto Kurogane from The Bloodedge Experience.
  • Cliffhanger: The end of the group's journey through Wonderland cuts back to the Mysterious Observer, who noticed that Naoto Kurogane has entered a time rift that brought him to Kingdom Hearts.
  • Cool Big Sis: Aqua seems to be taking up the mantle for Sora. She even gives him a sisterly glare of disapproval when he forgets to include Donald in the list of friends they need to find when talking to Tarzan.
  • Dark Is Not Evil:
    • Ragna ends up having to put up with people assuming he's evil due to his dark abilities. Leon questions him on why he uses darkness, with Ragna responding that he's simply used to it.
    • In the spur of the moment, Aqua ended up using darkness, which shocked her as she knows that she didn't succumb to it.
  • Deity of Human Origin: The Observer's dialogue in chapter 8 implies that he was once human.
  • Even Evil Has Standards: Played for Laughs, but even the Heartless find Wonderland's lack of logic and utter wackiness tiresome.
  • Facepalm: Ragna does this when it proves that the insanity of Wonderland is against them during Alice's trial, despite the irrefutable evidence that she's innocent. Even the Heartless that was actually guilty face-palms at this.
  • He's Back: Hazama returns and teams up with the villains.
  • Hidden Depths: Hazama tells Riku that he knows what it's like seeing people you know opposing you, indicating that he may have at least had something resembling regret for his actions before he threw that away.
  • In the Hood: The unknown observer wears a hood that completely hides his face.
  • Know When to Fold 'Em: The Heartless that was about to attack Sora in the Third District of Traverse Town had high confidence that it could take on an inexperienced Keyblade wielder, but once Ragna shows up, it cuts its losses and leaves. It returns with an entire hoard of Heartless after Ragna and Sora fight Leon. This forces them to retreat with Merlin's aid.
  • Let's You and Him Fight:
    • Ragna and Sora end up fighting Leon due to them believing that Leon was after the Keyblade. Thankfully, Aqua, Terra, Yuffie, and Merlin intervene before it got too violent.
    • Maleficent has Riku briefly fight Hazama to test the boy's power. While he's thoroughly outclassed, he does manage to score a hit, a blocked one, but still a hit. This is enough for Maleficent to start sending Riku out to perform tasks for her.
  • Only Sane Man: More like only sane group. Terra, Aqua, Ragna, Donald, Sora and Goofy start getting really fed up with Wonderland's insanity. The former three especially.
  • Pride: Donald is very proud of his summoning abilities and dislikes the fact that the summon gem prefers Sora over him. He also looks down on lesser worlds, as he didn't believe that King Mickey would be on a "back-water" world like Deep Jungle.
  • Purple Eyes: The unknown observer's eyes are described as being violet in color.
  • Screw the Rules, I'm Doing What's Right!: Donald and Goofy tell the group that they shouldn't get involved with the affairs of other worlds due to meddling. Aqua points out that this is a rather dumb rule since the Heartless are meddling and doing so is literally the only way to stop them.
  • Seen It All: Ragna doesn't react much to Donald and Goofy (magic wielding anthropomorphic animals) due to all of his past experiences. Wonderland, however, throws him for a loop.
  • Summon Magic: The summon gem given to Sora by the Fairy Godmother allows him to summon souls that narrowly escaped the destruction of their world. It only works with Sora as it outright snarled and roared at Donald when he tried to use it.
  • Suspiciously Similar Substitute: Aqua and Terra have a small talk on the Gummi ship about how Sora is extremely similar to Ventus. Terra brushes it off as a coincidence, but also notes the similarities.
  • Translator Buddy: Donald and Goofy by virtue of their watches, which are equipped with universal translators that let them communicate with anyone or anything, even animals.
  • The Watson: Because Ragna and Sora are new to how things work in Kingdom Hearts, they need things explained to them from time to time, such as how magic works.
  • World of Weirdness: Wonderland. The entire group gets frustrated with this very quickly.
