A deadly viral outbreak in Russia somehow comes to the attention of "Third-I", a top secret Japanese investigative group under the Public Security Intelligence Agency, and their top hacker, student Fujimaru "Falcon" Takagi. Through a complex and disturbing web of deceit, lies and covert-ops, Takagi and his friends must help Third-I prevent a dangerous cult from initiating their "Bloody Monday".A manga trilogy written by Tadashi Agi and illustrated by Megumi Kouji. The first season of the manga published from 2007 to 2009 with 11 volumes. It is later adapted into a live-action adaptation with 11 episodes. The second season of the manga was published from 2009 to 2011 with 8 volumes. The sequel of the live-action adaptation was out on 2010 with 9 episodes. However, its plot is very different from the manga's second season. The third and final season of the manga was out from 2011 to May 2012 with 4 volumes.Not to be confused with Bloody Monday which is either a 1855 riot in Louisville, Kentucky, the Claudy bombings in 1972 or the Częstochowa massacre in 1939
Guile Hero: Falcon often figures out what his opponents are trying to do, and regularly comes up with counter-plans to manipulate them to his advantage. The success rate, on the other hand, is iffy at best because his opponents are Magnificent Bastards in their own right.
Hacked by a Pirate: The lead character Fujimaru, known as 'Falcon', always leaves his personal symbol of a diving falcon at the screen of every computer he visits as a calling card.
And look at the eyes of anyone who's in full-on cultist mode. Scary!
Hollywood Hacking: Computer security is portrayed accurately, with bad guys employing tools that would give the NSA fits — but which takes the Falcon five minutes to crack the Third-I mainframe, including a two minute bathroom break.
Loads and Loads of Characters: The series start off as just a few high school kids trying to outsmart a teacher. Later on we have more than a dozen of main characters. The story reaches a point where if a minor or secondary character appears at least once then they'll play a larger role in the future. Heck by the end of the manga we still have new major characters appearing.
Chapter 86 shows you how large the current cast of main and secondary characters is. That's excluding all the dead and minor characters.
And now there's a whole new group of terrorists, the Shooter of the Magic Bullet, in the sequel of the manga.
Oblivious Younger Sibling: Subverted for Haruka. Though Fujimaru and Ryuunosuke tried their best to keep Haruka from getting involved in the trouble that they've gone through, she is still aware that they're up to something. In the last season, she is aware that Fujimaru is involved with the hostage situation.
Parental Substitute: Sayuri acted as Fujimaru and Haruka's guardian when their dad is on a run from the authorities. Though that ended when she turns out to be The Mole. Her replacement, Minami, continues her job onward together with Kanou.
Rapid-Fire Typing: Done by all the hackers during the tense moments. Averted in some cases where the hacking is done by software loaded in a USB key.
The Rival: Hornet, who doesn't show up until Chapter 84.
Rule of Cool: While Falcon is described as a "wizard" class hacker in-universe, many of his feats are impossible in reality given the time it takes to accomplish it, or the computing power required to accomplish such feat in that time frame. Or simply impossible with the lack of equipment.
Another Dark Action Girl is Alissa, the only other surviving member of Nikolai's "Dream Team" until she was killed along with Pres. Curtis.
Air-Vent Passageway: Used to break into a nuclear reactor chamber. It's a tight fit but an injured Hibiki manages.
Artistic License - Military: Pandora's Box, the nuclear launch control system carried with the President of the United States. The equivalent object in reality is referred to as a nuclear football, and cannot be used to launch nuclear missiles, only to authorize their launch. Peter Pan's plan to hold the world hostage would never work in reality because the Pentagon knows the Box is his goal and any authorization coming from it would be disregarded.
Bittersweet Ending: Borderline to Downer Ending. Despite that Japan is saved again and that Peter Pan and his supporters got what they deserved, the real Hibiki is still missing and the Prime Minister is revealed to be the leader of the terrorists and the man responsible for Ryuunosuke's death.
Call Back: The monstrously perverted teacher from Season 1 helps release a member of the terrorists' memories, after attempting to sexually assault his former "sex-slave".
The deadline for the threat is again on a Monday, which is lampshaded by Fujimaru.
Remember the Bloody-X virus? It's BAAAAAACK!
Child Soldier: While we don't know how old Hibiki is, it's clear that she's been a well-trained soldier for most of her life Three generations prior to conception, in fact.
Cloning Blues: Hibiki is one of eight clones created from the genetic material from three generations of her country's best agents, and possibly the only one who ever questioned her training. Two of her "sisters" have since entered Japan.
Defecting for Love: Hibiki, who is a foreign agent trained to be emotionless and efficient, defrosts when she sees the Takagi family dynamics, and completes her Heel-Face Turn when she falls in love with Fujimaru.
Defrosting Ice Queen / What Is This Thing You Call Love?: Hibiki is shaken by Fujimaru's dying father's decision to give his kidneys to his ailing daughter and it appears that she's thinking about the families of the victims for the first time; most significantly she's stopped threatening to kill herself.
Fujimaru: I can't believe you're getting jealous over me caring about my own sister! Hibiki: Jealous...? I see, this is jealousy! Hee hee, this is the first time I've been jealous!
Fake Defector: Ryuunosuke Takagi. He pretend that he betrayed Third-I and defected to Shooter of the Magic Bullet so he can be close to Alexei and to whatever he's planning. However, Alexei eventually learns about this and fatally shoots him.
Government Conspiracy: It's revealed in the end that Prime Minister Kujo is pulling the strings behind the terrorist attacks which results to the deaths of several Third-I agents, including Ryuunosuke Takagi.
Hostage Situation: Averted a bit. The "fake" Hibiki held a clinic doctor hostage to make Fujimaru gain access to Pandora's Box. Too bad the doctor was killed before Third-I agents gunned her down.
In Love with the Mark: Hibiki. She was sent to watch over Fujimaru until Pandora's Box is safe. However, her time spent with Fujimaru for the past months made reciprocate her feelings with him. Of course, her superiors were not pleased.
Info Dump: Fujimaru's workmate-turned-mole Hibiki reveals a lot of information about "The Last Emperor" — so much so that Fujimaru tells her to stop and another person calls her Wikipedia-chan.
No ka-boom, but Peter Pan's plan is to use the Third Emperor demand enough money to throw an entire country's economy into chaos.
Our Presidents Are Different: President Adams sure looks like George W. Bush and is a bit overconfident, but he also seems to be fairly level-headed. He's a combination of President Jerkass and President Target.
The current Japanese Prime Minister, Kujo, is Prime Minister Personable, at first. But later, he's actually Prime Minister Evil.
Put on a Bus: We only get to see Aoi on the first few chapters but then, we never know what happened to her.
Psycho for Hire: "Peter Pan", Nikolai, and the dozens of guys he hired then put through an impromptu Deadly Game to get the best of the best for his "Dream Team".
Retired Badass: Fujimaru hasn't even touched a keyboard since "Bloody Monday" but this is just a ploy to avoid involving his friends again.
The Rival: Peter Pan, who is said to be what Falcon could become given a few years (which should already give some indication how powerful he is), and who had a hand in making Falcon the master hacker he is in the first place.
She Cleans Up Nicely: Minami. Her Third-I teammates were surprised about this, at first. Later, she does it again in the last season.
Too Dumb to Live / What an Idiot: The Minister of Justice ("They've all been bad"), who think Third-I is wasting time and money trying to attack Arthur & Co. and they should just get rid of the bureau anyway.
The American head of security, who's so overconfident he doesn't realize that Peter Pan has already taken over a powerful spy satellite.
President Adams, youcan make a deal a terrorist who previously said she could have killed any one of the dignitaries by moving into the penthouse next door and apparently forgot a retina scan doesn't require your eyes to be attached to your head.
We Have Reserves: Hibiki won't hesitate to kill herself if the situation goes south since whoever she works for will just send someone else (in fact, they'll likely send seven identical people). The Third-I crew decides to keep her alive just in case whoever they send is worse.
Billy Needs An Organ: After defeating her clones, Hibiki was stabbed in the heart by one of them near the end. J suggested to have her a heart transplant from the clones' fresh corpses.
Brainwashed and Crazy / Cloud Cuckoo Lander: Kaname — daughter of Storyteller, "wife" of season 1's cult leader, and mother of Otoya and J/Jun — has undergone some sort of mind-meld with her father so she knows exactly how he thinks in case she needs to replace him; in the meantime she acts so loopy even Maya doesn't know how to handle her.
Broken Pedestal: Though Otoya did find out that his grandfather is behind the attacks, it's only in his confrontation with him where he calls him out for his actions which results not only to the death of his best friend and his girlfriend's father but to the deaths of many people who served Japan.
The Bus Came Back: Aoi appears near the end of the manga where she attends Fujumaru's and Otoya's double wedding.
Calling the Old Man Out: After attempting to kill Otoya for his refusal to join, Kaname shoots Masamune and calls him out for taking away her sons from her.
Darker and Edgier: More serious than Season 2. Not to mention, there's the lack of comedy in it unlike the first two.
Despair Event Horizon: Storyteller's is from his parents dying in the Hiroshima bombing; unusually it's triggered in middle age.
Kaname: After all the practice I went through, I understand your hatred more than anything. But even if my heart is running on hatred, I also understand really well it won't restore anything. That's why it hurts. That's why I will end this now, father.
Heroic Sacrifice: J's terrorist friend (who was a member of the group that attacked Otoya as a kid) takes a bullet to save Otoya and Haruka; Hibiki takes a knife to the chest for Fujimaru but, fortunately, she survives, thanks to the heart transplant from one of her clones.
Now What?: Since the Storyteller problem has already been dealt with, J and companions don't know what to do.
Not So Different: Maya and Hibiki: born in a Wretched Hive and forced into espionage, they're offered Japanese citizenship when their duties are complete (plus a ton each of gold and silver for Maya), and both become a little more peaceful in the end.
Official Couples: To the point where they have a double wedding ceremony in the end!
Otoya and Haruka. In fact, when they both confront Prime Minister near the end, Otoya admits that Haruka is his girlfriend.
Fujimaru and Hibiki. Apparently, Hibiki mentions that once the mission is over, she wants to get married to Fujimaru.
Patrick Stewart Speech: Otoya, after refusing to join his grandfather and mother to join their cause, gives this to them that people, like Hibiki and, possibly, J, can change despite the countless wars that humanity experienced.
Power Tattoo: Not magical but all the terrorists have big omega symbols on their faces that can only be seen with the masks.
Red Right Hand: Maya's mole, the only part of her appearance she refuses to change or cover up even when crashing the Kujou and Fujimaru double-weddings.
The Revolution Will Not Be Civilized: Storyteller's "prologue" involves shooting a half-dozen hostages on live TV — including children — in order to get the other countries to sell their US dollars and make the Yen powerful. His lackey "Seagull" seems hesitant, so someone else does it. Fortunately the order was given by Fujimaru with a voice synthesizer and "someone else" was Hibiki with a taser.
Spy Cat Suit: Hibiki dons one after infiltrating a diplomatic party
Taking You with Me: Kaname commits suicide by jumping off the building and drags Masamune along.
Theme Naming: Storyteller's group uses birds for code-names like shrike and kingfisher.
Took A Level In Bad Ass: Haruka: she allows herself to be taken hostage so Otoya can escape, plants an extra explosive for Fujimaru when the terrorists unwittingly move them around, holds Otoya's arm up so he/they can shoot the last Hibiki clone who's aiming at Fujimaru, and literally helps Otoya stand up to his grandfather.
Tragic Keepsake: Otoya gives J their mother's watch; J surprises his hacker pal Michael by not tossing it.
True Companions / Band of Brothers: Throughout the series, Fujimaru sees Third-I as this. He owns them for protecting him and his loved ones since the first season when his dad went on a run.
Unwitting Pawn: Third-I have no idea that they're being used by Prime Minister Kujo. But as the story progresses, they know eventually that he's in charge of the terrorists.
Storyteller: The idea that violence cannot change things... is a lie. Every time the world has been changed it was by unilateral violence. [...] We are sacrificing ourselves as terrorists to make this nation ( —Japan—) a truly independent nation that has pride!!
Well-Intentioned Extremist: Japanese Prime Minister, Masamune Kujou (and Mamiya, the only terrorist whose POV we get to see). His reasons that ever since World War II, he feels that US influence caused so much chaos around the world. The only option, after the cult and Shooter of the Magic Bullet failed, was is to make Japan into a true independent nation.
What the Hell, Dad?: Masamune instill his ideals and hatred to his own daughter, Kaname. But he secretly took away her two sons from her and unfortunately for dad, she realized it and took matters into her own hands.
What the Hell, Hero?: Hibiki after gunning down what appeared to be hostages. They're actually bad guys.
Hibiki again: she kills a bunch of bad guys, but only to prevent Otoya from becoming "sullied".
J has to keep reminding Fujimaru that Everyone Lives isn't an really option but Fujimaru does his best anyway.
White Mask of Doom: Storyteller's terrorists wear them, as do the disguised counter-terrorists Too bad the good guys don't seem to know about the invisible face paint....
A World Half Full: At the end, this is pretty much the surviving characters' perspective. They know that they cannot expose Masamune's actions to the public as it would create more chaos. But as Kirishima stated, they still have to hunt down the surviving terrorists who are still using their cover positions in the JSDF. And Otoya, as what he said in his Patrick Stewart Speech, decided to become a politician as he wants to make a difference.
