A group of young spies engaged in espionage at a spy training institute in the wartime Showa era (1937). This mystery anime is super engaging, with the characters even betraying each other.
With the fires of war still raging in autumn 1937, the Imperial Army lieutenant colonel Yuki establishes the secret "D" spy training institute. Under his watchful eye, young spies train in all of the necessary skills for the job -- use of explosives and wireless technology, operating cars and airplanes, and tricks like pickpocketing and safecracking. Once trained, they are dispatched to various locations. Spies must not be seen or heard, and operate under a mantra of "don't die and don't kill." For spies at D, taking a life -- whether their own or others' -- is the last resort. Central command with the army furiously opposes their initiatives, and they find themselves in a web of global lies and deceit as they must even betray their own and outsmart the enemy.
In the original novel, all personnel at D do not know their teammates' respective skills. The reader, unable to see their faces, is further plunged into mystery. In the anime, the characters have names -- albeit aliases -- giving them a more complex personality. By putting a name to a face, there is new drama in the way these spies all but try to cloak their existence while carrying out intelligence activities. Even though they are colleagues, there is something gripping in the way they treat each other coolly and with distance. With visual tricks on view and foreshadowing hinting at future developments in the series, the complex story is one that won't reveal itself on one watch through. The show perfectly succeeds at getting viewers addicted to its plot.
