Ep 2. The Black Order

The D. Gray-Man season 1 episode 2 is titled "The Black Order" and features the main character, Allen Walker, as he continues his journey in the fictional world filled with demons called Akuma. The episode introduces the audience to the Black Order, an organization that fights against the Akuma with the use of Innocence, a substance that provides superhuman abilities to its wielder.

The episode starts with Allen's arrival at the headquarters of the Black Order, where he is greeted by a man named Komui Lee, who shows him around the place. Komui Lee is the chief officer of the Black Order and assigns Allen as an Exorcist, someone who uses the Innocence to fight the Akuma. Allen meets other Exorcists who are experts in their own abilities, such as Lenalee Lee, Komui's sister, who possesses superhuman strength and agility, and Yu Kanda, who wields a sword infused with Innocence.

As Allen settles into his new surroundings, he is briefed about the history of the Black Order and its mission to defeat the Millennium Earl, the main antagonist of the series. The Millennium Earl is an immortal creature who creates Akuma by using the souls of the deceased and corrupts them with his own power. The Black Order's primary objective is to stop the Millennium Earl from wiping out humanity with his army of Akuma.

The episode also highlights the importance of Innocence and how it is vital in the war against the Akuma. Innocence takes the form of a weapon that varies from person to person. Lenalee's boots, for example, can transform into multiple forms that allow her to move quickly through various environments, while Allen's claw-like weapon is capable of manipulating the molecules of matter. The existence of Innocence is kept secret from the general population, and only a select few Exorcists are aware of its existence and capabilities.

As Allen trains under the guidance of his new mentors, he learns more about the Black Order and the various departments within the organization. He is also introduced to General Cross Marian, a former Exorcist who abandoned the Black Order years ago. Cross appears to be a mentor to Allen, but it soon becomes apparent that the two have a complicated history. Cross gives Allen a mission to retrieve a fragment of Innocence from a mysterious organization known as the Noah Clan.

Overall, "The Black Order" provides essential context about the titular organization's history and purpose within the series. The episode introduces new characters and highlights the significance of Innocence and its role in fighting the Akuma. Additionally, it sets up the overarching conflict between the Black Order and the Millennium Earl, as well as the various obstacles that the Exorcists will face throughout the series.
