As she heads off to her entrance ceremony at Sainotama Girls' High School, Akane Kikuchi muses over her grade school dream of becoming a manga artist and the lack of progress that she has made. When she finally arrives at school, she is surprised to learn that she is once again in the same class as her two best friends: the deadpan and emotionless Shiori Saginomiya and the hyperactive and ridiculous Nozomu Tanaka. Tanaka then comes to the obvious realization that she can't achieve her grade school dream of being popular with the boys and getting a boyfriend by going to an all-girls high school. In desperation, she begins asking the girls in her class to introduce her to their guy friends. Her classmates, however, are anything but ordinary. From a grandmother-loving loli to a reclusive chuunibyou to an overly analytical stalker, each one is given a fitting nickname by Tanaka to accentuate their weirdness. And so begin the wasteful days of these high school girls, each day kicked off with a simple question: Hey, wanna hear something amazing?

Still in pursuit of her ambitious goal, ingenious arms dealer Koko Hekmatyar, inexpressive child soldier Jonathan “Jonah” Mar, and the rest of their squad continue their mercenary activities. From professional assassins to private militaries, the group's work constantly puts them in the face of danger. But internal conflicts soon arise after Renato R Socci, one of Koko's bodyguards, is revealed to be an undercover agent for Operation Undershaft—a plan devised by the CIA to infiltrate HCLI and exploit Koko as a tool. Shocked by his betrayal, Koko's leadership is needed now more than ever to rally her squad and rebuild their foundation of trust before they are torn apart. Jormungand: Perfect Order follows Koko and the rest of her crew as they take on persistent adversaries, overcome internal struggles, and make Koko's vision of world peace a reality—where everything is in perfect order.

Specials included with the Blu-ray box set releases of Joker Game.

Brought up in a conflict-ridden environment, child soldier Jonathan Jonah Mar hates weapons and those who deal them. But when Koko Hekmatyar, an international arms dealer, takes on Jonah as one of her bodyguards, he has little choice but to take up arms. Along with Koko's other bodyguards, composed mostly of former special-ops soldiers, Jonah is now tasked with protecting Koko and her overly idealistic goal of world peace from the countless dangers that come from her line of work. Jormungand follows Koko, Jonah, and the rest of crew as they travel the world selling weapons under the international shipping company HCLI. As Koko's work is illegal under international law, she is forced to constantly sidestep both local and international authorities while doing business with armies, private militaries, and militias. With the CIA always hot on her trail, and assassins around every corner, Jonah and the crew must guard Koko and her dream of world peace with their lives or die trying.
