Akatsuki...

Pain, the leader of the Akatsuki, whose real name is Nagato Uzumaki, had a teammate named Yahiko. After enduring so much pain, witnessing Yahiko's death, and seeing countless wars, he became who he is today. Konan was trained by Jiraiya alongside her partners Nagato and Yahiko. She witnessed many wars throughout her life, but none shattered her as much as seeing her beloved Yahiko die before her eyes. Since then, her role has been to protect Nagato at all costs. Deidara, an artist of explosive clay art with a tic of saying "Hum," was expelled from his own village, the "Hidden Stone Village," for using a forbidden explosion jutsu, but he doesn't care because "What matters is true art... and true art is an explosion, hum." Obito is a Uchiha who helped Itachi annihilate his own clan. Obito was a boy who dreamed of becoming Hokage, but after seeing his beloved Rin die on a mission, he lost the only light he had and has lived with a constant emptiness in his heart ever since.
Orochimaru is a cruel and psychopathic scientist who aims to become immortal and learn new jutsus. He experiments on orphans and trains young people to become more powerful, later using their bodies as hosts for his soul. Itachi Uchiha is the man who annihilated his own clan to save the village, sparing only the life of his younger brother Sasuke. Today, Itachi is known as "The Traitor." Hidan is a religious devotee and servant of the god Jashin. He is a fanatic for blood and sacrifices; he sacrificed almost everyone in his village and then cruelly abandoned it simply because it became a peaceful place. Kisame is a shark-like man. He was one of the Seven Swordsmen of the Mist Village and the strongest of the seven. One day, Kisame's sensei tried to deceive him, and Kisame killed him repeatedly. His only faithful companion is his sword, "Samehada." Black Zetsu is the son of Kaguya, the Otsutsuki goddess, while White Zetsu was created by Madara, and both are mysterious figures.

Sasori is an artist of eternal art; he's a puppeteer who believes that 'eternal art is the only true art.' He always argues with Deidara when the subject is seeing art differently. Sasori transformed his own body into a puppet to live for many years and have his art recognized. Kakuzu is a greedy, fanatical figure obsessed with money and economics. He doesn't care about anything except money; for him, only money has value. His story is marked by the betrayal of his own village, the pursuit of immortality, and even more money. He also possesses five hearts. Everyone in the Akatsuki is dark and difficult to communicate with; they all only care about themselves. Deidara is the only one who is less complicated; he's the least dark of the Akatsuki, but don't underestimate him. He's less complicated but somewhat rigid. Deidara also has a tic of saying "Hum" every time he speaks long words or phrases, or when he says "Explosion, hum." Obito uses the "Tobi" persona to forget the emptiness inside him, even knowing he'll never truly forget it. Even acting like an idiot in "Tobi" mode, he's not easy to deal with, especially in "Obito" mode where he's himself. Hidan is a very sharp-tongued immortal; he has no shame or fear of anything and is completely rude.

Yahiko, Nagato, and Konan created Akatsuki during the Third Shinobi World War with the goal of bringing peace and ending their country's suffering without resorting to violence. After Yahiko's tragic death, Nagato took command, using Yahiko's body as the Pain Path, and the organization was corrupted and manipulated by Obito Uchiha, who acted in the shadows under the name Madara Uchiha, and by Black Zetsu, transforming it into the criminal and mercenary group we know today.
The Akatsuki's objective is to capture the tailed beasts, seek peace through suffering, and then resurrect Madara to finally reach the final part of the Moon Plan. Akatsuki is an organization of S-rank ninjas and renegades who have abandoned or been expelled.
