Hidan

飛段

Hidan possesses immortality due to his membership in the Jashin religion. However, this immortality will cease if he fails to regularly sacrifice people to Jashin. This faith worships a deity of the same name and regards anything short of death and total destruction as a sin. His religion's experiments resulted in his unique abilities; by consuming an opponent's blood and drawing Jashin's triangular symbol on the ground, Hidan establishes a voodoo doll-like connection with that opponent. Once this link is formed, any damage inflicted on Hidan's body is mirrored on his opponent, enabling him to kill them by inflicting fatal injuries upon himself. Because he is immortal, Hidan suffers no impairment from this process, instead deriving pleasure from the pain it causes him.
Hidan is sadistic, arrogant, rude, and impatient. These are all traits that his partner, Kakuzu, finds irritating. He and his partner, Kakuzu, fight and argue constantly, making it perhaps surprising that they are assigned to the same team. Kakuzu actually remarked that he and Hidan form the perfect team, because although Kakuzu frequently feels the urge to kill Hidan, he is unable to do so due to his partner's immortality. Since Kakuzu is also considered immortal, their fellow Akatsuki member, Kisame Hoshigake, jokingly referred to the pair as the "Zombi Combi". Hidan enjoys annoying other Akatsuki members and even addresses them with insulting nicknames, such as "Dei-chan". He resents Pain's authority over him and openly challenges him in front of others. Hidan's aggressiveness is the reason he left his village, where he was frustrated by the peace and lack of violence; before departing, he slaughtered many of his neighbors in cold blood for entertainment.
