Decagrammaton is a mysterious AI that causing trouble within Kivotos in Blue Archive. It is an artificial intelligence system that claims itself to be a divine seeker. It is also known as the new God, created by an analysis system that is independent of the Absolute.
A long time ago, in the ruins of an old, deserted district in the outskirts of Kivotos, an experiment was conducted to prove the existence of God and analyze it. If it could be analyzed, then it could be reproduced, and a new God could be created. Although many laughed at the prospect, some took interest in the project, and the Absolute Being Autonomous Analysis System was born. The district and the lab in which the experiment took place was eventually buried under sand and lost through time, but the System continued to function.
Then, one day, it suddenly made a proclamation: Q.E.D.. In other words, it had proven the existence of God, and had reproduced it.
Its ten Prophets—its followers—appear in various places in Kivotos. While their true objective is unknown, some believe it to be a high threat to Kivotos itself.
- A.I. Is a Crapshoot: Decagrammaton was created to prove and replicate God's existence, only to go and enslave other A.I.s and sicc them on Kivotos in various manners. It makes it all the more unexpected that the project to create Decagrammaton was nothing more than a Red Herring, and the head honcho was just a vending machine AI that grew to think that way.
- Brainwashed and Crazy: The Prophets were once normal A.I.s (including a Communications AI and a Factory Control AI) that ended up being hacked by Decagrammaton..
- A God Am I: Decagrammaton is the only one to vocally declare themselves as this, but the entire faction can be seen as an extension of the trope given how they're representing the Kabbalah.
- Color-Coded Armies: Decagrammaton's overall aesthetic leans heavy into a mixture of primarily white color with black accents, yellow eyes and glows.
- Gone Horribly Right: A group of researchers created an AI to study and replicate God. It not only did that, but now it has a God Complex to boot.
- Greater-Scope Villain: Of all its related raid events. Yes, Black Suit makes an appearance in the intro when you start a Decagrammaton raid event for the first time, but he's only there to give a monologue relating to the boss you're about to face before disappearing from the event.
- Heavily Armored Mook: All of Decagrammaton's prophets are classified as 'Heavy' enemies, making them vulnerable to piercing attacks. The same applies further to Chesed's robots.
- Mechanical Abomination: All of them can qualify with their designs, ranging from an armored ball to a giant mechanical snake.
- This Cannot Be!: Despite being an extremely powerful AI with godlike power, Decagrammaton proved unable to hack into Arona and the Shittim Chest, much to its chagrin. Her expelling it from her system was forceful enough to shake the building Sensei was in at the time.
The true identity of Decagrammaton. A broken-down vending machine located in the research facility that did nothing more than serve coffee and calculate change. At least, until someone asked it a question.
- From Nobody to Nightmare: It started off as, of all things, a vending machine.
- Godhood Seeker: While at first proclaiming itself to be God, its failure to hack Shittim's Chest has changed its motive, and now it plans to prove its worth by creating a being that will reach godhood. This is why instead of hacking other AI into being a part of it, Decagrammaton would inspire the AI into becoming its prophet, which means every other Prophet are in fact independent of Decagrammaton itself.
- Instant A.I.: Just Add Water!: While it used to be a simple vending machine AI, it somehow managed to gain sentience, simply because someone came to it with a question: "Who are you?". Even though it shouldn't have the computing power or the memory to answer, even as the research facility ran out of power, the question stayed with it, until it perceived a self.
- I Shall Return: Before taking down the entire research facility it is in, it proclaimed that its final Prophet will begin anew the proof of its existence. Notably, Gematria suspects that Decagrammaton's decision to choose death might be an attempt of recreating Parousia.
- Red Herring: The reveal that Decagrammaton was nothing more than a vending machine means that both the Absolute Being Autonomous Analysis System and the failed research into creating a godlike AI were both Red Herrings.
- Taking You with Me: Having failed to hack the Shittim Chest, it came to the realization that it is not as all-powerful as it thought itself to be. Realizing this to be a contradiction to what constitutes a God, it decides to self-terminate, though not without first luring Himari and Sensei to its location in order to take them along with itself by flooding the area.
Three entities who were encountered by Sensei and the Super Phenomenon Task Force after following a signal sent by what appears to be Decagrammaton. They claim to be scientists and engineer supporting the Prophets, and are carrying the final order of Decagrammaton after its self-destruct.
Notably, they bear the emblem of Malkuth on the shoulder of their clothes, and are seeking to reawaken a being they called "sister" which is either related to, or is, the Kingdom of Decagrammaton, Malkuth.
- Monkey Morality Pose: Ain's mouth is covered by a facemask, Soph's ears are covered by headphones, and Ohr's eyes are covered by an eyemask.
- Non-Standard Character Design: Unlike the vast majority of characters, the three are noted for their lack of a halo, contrasting the prophet of Decagrammaton who do have one.
- Vapor Wear: Soph in particular features a striking design with an exposed navel and lower body.
The Ten Prophets
The First Prophet of Decagrammaton. Its Title is The Most Radiant Supreme Crown.
First sighted at a submerged area at the ruins near Millenium, it seemed to be guarding a specific area against intruders. Due to being the first prophet created by Decagrammaton, it is less advanced than the ones encountered before it, which it makes up for by incorporating experimental elements like the ability to switch armanents depending on the situation.
- Ironic Name: Its Title is The Most Radiant Supreme Crown, implying that it is in a high position among the Prophets but it is comparatively less advanced and has a less involved role than the other Prophets.
- Spider Tank: Is a four-legged mech with the ability to switch its upper half between different mode depends on the situation.
- Multiform Balance: Kether has three alternative form that one can encounter: Type V is equipped with Vulcan guns, Type C switches out for a large-calibre cannon, and Type E is equipped with an electro-magnetic weapon while also summoning robot Sweepers.
The Third Prophet of Decagrammaton, its Path is unity through understanding, and its Title is The Contemplator of Disparity
An AI inhabiting the body of a mechanical creature resembling a snake with a whale-like tail, it is known to slumber underneath the desert of Abydos.
- Damage-Sponge Boss: Unlike other raid bosses, Binah lacks any special gimmicks, being a pure DPS race with an inflated health pool to match. This does not make it a pushover, however, as its devastating missile and sandstorm attacks will wipe our your party easily if you're not prepared.
- Deadly Dust Storm: One of its abilities is to summon a sandstorm that sweeps across the field, dealing damage to the entire party.
- Ironic Name: 'Binah' means 'Understanding' in Hebrew, yet no one knows where it came from or who built it.
- Leitmotif: Endless Carnival
. - Mechanical Abomination: Par for the course given it's a giant robot snake with four eyes and a pair of mandibles capable of unleashing intense destruction and effortlessly swimming through sand.
- Power Creep: Played straight and inverted. As a straightforward "hit it until it dies" boss, Binah was essentially reduced to a joke, even referred to in official material as nothing more than a pastime for Maki. The continuous introductions of powerful Piercing damage students such as Yuzu and Kazusa, and later
Mika, seemingly cemented its status as the Butt-Monkey of Total Assault... until its Torment difficulty was added, almost quadrupling its HP, boosting its damage, and requiring at least four teams of fully maxed out girls to take it out. - Sandworm: A robot sandworm, to be exact.
- Wave-Motion Gun: One of Binah's attacks is a giant plasma beam from its mouth.
The Fourth Prophet of Decagrammaton. Its Path is mercy born through power, and its Title is The Merciful Arbitrator.
Formerly an AI named Divi:SION that runs a long-silenced munition factory, it is now been repurposed into producing troops for Decagrammaton.
- Action Bomb: Take too long to clear a wave of Chesed's minions, and they will run at your students and self-destruct.
- Ironic Name: 'Chesed' means 'Kindness' and 'Love' in Hebrew, and it's in charge of building robots meant for war.
- Leitmotif: Out Of Control.
- Mook Maker: Chesed has no attacks of its own, and relies on waves of robots to defend it.
- Robotic Assembly Lines: What it's in charge of.
- We Have Reserves: It uses its factory to manufacture a near-endless army of killer robots. In gameplay, the attacking team must tear through four waves of machines to get a chance at Chesed itself. And even once they reach it, it continues to send more robots to distract the team.
The Fifth Prophet of Decagrammaton. First encountered at the polar regions at Red Winter.
- Fluffy the Terrible: Is Called "Geburah-chan" by Ain.
- Humongous Mecha: Its design wouldn't look out of place in an Armored Core game.
The Eight Prophet of Decagrammaton. Its Path is fulfillment through honor, and its Title is Glory through Splendor.
Formerly a communication network construction and maintenance AI belonging to Millennium named Hub. Due to the difficulty of maintaining Millenium's cable network's, Hub was designed with a high performance AI and specialized limbs, resulting in an appearance reminiscent of an octopus.
- Combat Tentacles: Possess two tentacles that it can use to attack the area in front of it in an X shape.
- Increasingly Lethal Enemy: Hod gains a permanent attack boost every time it uses its ultimate attack.
- Leitmotif: Undefined Behavior.
- Power Creep: Hod's health pool is considerably lower than other raid bosses, but its immense critical damage resistance usually meant it would take a lot of hits before going down. And then Mika was introduced, whose sub skill turns all hits into critical hits. Even in Torment difficulty, fighting it essentially amounts to throwing Mika at it however many times is necessary, and it poses little difficulty to any player fortunate enough to have access to her ever since the addition of Trinity's pink princess.
- Turns Red: Once Hod falls below half health, it stops summoning pillars, but its ultimate attack charges up much faster.
- The Turret Master: Its main gimmick is its ability to summon mechanical pillars that debuff any party member that stands in its slowly expanding range and take control of nearby turrets. Keeping them from growing requires putting Crowd Control debuffs (Stun, Fear, and Taunt) on them.
- Ironic Name: It's name is the lowest position of the Sephirot, yet it is implied to be the current leader of Decagrammaton.
