Long ago, a terrible monster called "The Black Beast" appeared and began destroying everything in its path, spreading a toxic substance called "seithr" across the planet and threatening to cause The End of the World as We Know It. Humanity was on the verge of extinction when a group known as the Six Heroes arose and developed weapons to fight the Black Beast: the "Armagus", an artificial form of magic powered by seithr that anyone could use. With humanity empowered by the Armagus, the Black Beast was defeated and the Six Heroes disappeared into history. This event became known as the "First War of Magic", aka "The Dark War".
Humanity began reconstruction in low-seithr areas and formed the Novus Orbis Librarium note (otherwise known as the N.O.L. or "The Library") to govern the world and the grimoires that controlled the Armagus. However, the N.O.L. quickly grew into The Empire and began to abuse their power, aiming to create a hostile monopoly on the Armagus grimoires. A resistance movement attempted to rebel against the N.O.L's growing power in an event known as the Ikaruga Civil War (aka Second War of Magic), but were defeated. As a result, the N.O.L. imposed even harsher restrictions on the Armagus, making Armagus possession (outside of the N.O.L's own members) punishable by execution without trial.
In the year 2199, several branches of the N.O.L. are suddenly destroyed by a One-Man Army known only as "Ragna the Bloodedge". Wielding a powerful Armagus called the Azure Grimoire, he declares the start of a one-man war against the N.O.L. and their tyrannical grip on the world. In retaliation, the N.O.L. imposes the largest bounty in history to anyone who kills him.
As news spreads that Ragna has arrived at the 13th Hierarchical City of Kagutsuchi, a ragtag bunch of N.O.L. operatives, bounty hunters and vigilantes straight from the Dysfunction Junction descend upon the city, each one seeking out Ragna for their own purposes. Meanwhile, Ragna heads for the dark secret lurking in the centre of Kagutsuchi, a single purpose resting in his heart.
The game uses a 4 button system: Weak Attack (A), Medium Attack (B), Strong Attack (C), and a unique Drive Attack (D) for each character.
The Arcade version of Calamity Trigger was released on November 20, 2008, and console ports for the PlayStation 3 and Xbox 360 were released on June 30, 2009. The console version included online play, a new Story Mode that is set up somewhat like a Visual Novel, a new anime opening by J-Pop artist Kotoko as well as several new anime cutscenes, English voice acting, and much, much more. Console releases are sold in retail and premium editions which include a combo DVD, an artbook (several of these are now backordered, unfortunately), and a limited edition soundtrack, which includes every song in the game except for the main theme and the two extra songs for certain characters, and instead replaces them with remixes by rap artist Oh No. The European version was released much, much later. April 2nd, 2010, to be specific. As compensation, it has all the DLC included for free.
There's a PSP port, entitled BlazBlue: Calamity Trigger Portable, and a Windows PC version of Calamity Trigger, released for the Games for Windows platform on September 2, 2010. The latter is available for $35 and, much like the PAL release, for the fans who waited so long, includes all of the console DLC for free. The same PC port was brought to Steam (albeit without GFWL parts or online VS.) on February 14th 2014, then later on April 14th to GOG.com the same year.
Rebel 1, ACTION!
- American Kirby Is Hardcore: Or in this case, European Noel is Hardcore. The European cover shows Noel doing a pretty badass Pistol Pose with a dark brown background contrasting other covers' use of blue. The result makes it look more like a shooting game.
- Anger Born of Worry: During the True Ending sequence, after Noel saves Ragna from falling into the cauldron.
- Anyone Can Die: They can and often do in the story mode.
IncludingEspecially the main character, Ragna, who often dies in his own path. The "Groundhog Day" Loop makes it so that all of the endings are canon, while ensuring that no one is Killed Off for Real. In the True Ending, though, the loop finally gets broken and Nu-13 died in the process.
- Book Ends: The Ragna ending of Rachel's story mode ends with the same tea in the courtyard that it began with.
- Combo Breaker: Barrier Burst is used; its use has the penalty of the user temporarily taking 1.5x damage and being unable to use Barrier Block for the rest of a round.
- Cover Drop: The seal depicted behind the BlazBlue logo (and on the game over screen) finally shows up in the story in the True Ending, when Ragna activates his Azure Grimoire.
- Didn't See That Coming: Hakumen says a variant of this in his Calamity Trigger Arcade mode when Nu-13 is the ninth fight, rather than the last one.
- Early-Installment Weirdness: The core cast is understandably compact for a first game, but where the real weirdness ensues is in the format of the Story Mode: the "Groundhog Day" Loop results in treating the game more like a Visual Novel of repeatedly tackling different routes to see their outcomes, with the cast often dying constantly in various horrible ways, especially Ragna. Thanks to the cause of the loop being shutdown in the True End, all the subsequent games would use character arcade and personal stories as ways to build them up as a more genre-traditional What If? approach, or focus entirely on more linear stories with none of the route shenanigans.
- Future Self Reveal: Through various hints scattered between their story modes, it's revealed that the legendary hero Hakumen who fought the Black Beast 100 years in the past is the future self of the largely villainous Jin Kisaragi due to a 100 year long "Groundhog Day" Loop.
- Gameplay and Story Integration: Hakumen and Nu-13 are monstrously powerful in-story. This is reflected in Story and Arcade Modes by only having you face their Unlimited forms.
- Glamour Failure: In the True Ending of CT, Hazama reveals that he is actually Yuuki Terumi. Interesting because his glamour failed more or less out of sheer enthusiasm.
- "Groundhog Day" Loop: All of the paths of the story mode in CT actually occur. It is implied that these events have been looping for some time and that Rachel is the only one of the main cast who is aware of it. The True End finally breaks the loop.
- Groundhog Peggy Sue: Rachel. It is due to being an Observer that she can "feel" the time looping, unlike the others. However, she can't exactly do things all by herself to correct it; she works more on trying to nudge other characters to do the right thing to end the loop. In the ending, Hazama/Terumi is revealed to be another one, and he also wants to end the time loop; unlike Rachel, however, he wants to turn the world for the worse. And as the loop is broken, the Takamagahara System summons Rachel for questioning.
- Ham-to-Ham Combat: Ragna vs. Jin. And you love them for it.
- Home Stage: Characters are typically fought on certain stages, with a few sharing them.
- Cathedral for Jin.
- Kagutsuchi Port for Ragna and Carl (PM 9:00) and Noel (AM 10:30).
- Alucard castle for Rachel.
- Lost Town for Taokaka.
- Orient Town for Litchi and Tager.
- Area 28 for Arakune.
- Ronin district for Bang.
- Kiln for Hakumen and Nu-13
- Kick the Dog: Jin kills Noel in his story mode. He's in crazy mode, so it's probably this trope.
- Long Song, Short Scene: "Love So Blue" (the vocal version of "Bullet Dance", Noel's theme) only plays for the Noel vs. Nu battle in the true ending. One of the combatants has an infinite heat gauge for this battle, so it will be over in 10 seconds. Fortunately, it can be selected in VS mode.
- Multi-Platform: The console port, being released on PlayStation 3 and Xbox 360, followed by its port to Windows PC.
- Poor Communication Kills: All of the people in the story who know ANYTHING about what's really going on are either the villains (Terumi, Takagamahara), enormous assholes who can't be bothered to explain anything even to their own allies (Kokonoe) or people who can't tell what's happening because of being Observers (Rachel). Jubei, Hakumen and Kokonoe know a lot more about the Azure Grimoire than they're telling Ragna, Jin or Tager.
- At one point, Rachel even outright mocks Noel for all of the things Rachel knows that she doesn't know about herself, and then refuses to tell her anything.
- Power Up Motif: Bang Shishigami's Fu-Rin-Ka-Zan is a Super Mode that works like this: When you activate it, his power-up music begins to play loudly over the stage BGM, until the next round begins.
- Rank Inflation: In Online mode, players are awarded ranks that change depending on the user's player level. Ranks change every 5 levels of inflation up to 50, then every 10 levels up to 90, and the last rank is reserved for level 95.
- Independent fighters (Ragna, Rachel, and Arakune) start off as "Dine n' Dashers", then get "Risk Ratings" of "F7" to "F0", then progress from "E" to "A", then into "S" and finally "SS"
- Vigilantes (Tao, Carl, and Bang) are given different colors for their titles. Starting with "Novice" and ending at "Purple".
- Sector Seven (Tager, Litchi, and Hakumen) are given various animals. Starting with "Errand Boy", then going from actual animals like "Wolf" and "Lion" to mythical creatures like "Leviathan" and "Phoenix".
- The NOL (Noel, Jin, and Nu) are given military ranks. From "Private" to "Commander", then to elite royal ranks such as "Centuriones" and "Praefectus".
- Due to lack of coding, once you reach level 100, every character's rank becomes "(null)". Yes, (null). Arcsys basically tells you you've wasted your time.
- Regional Bonus: The European version includes all of the DLC, free of charge.
- Sean Connery Is About to Shoot You: The European box art for Calamity Trigger shows Noel in her Pistol Pose.
- Secret Final Campaign: Finish all characters' story modes, and you will unlock the final parts of the whole story.
