Hidan is an S-rank missing-nin who defected from Yugakure and later joined the Akatsuki. He is a devout worshipper of Jashin, and takes it upon himself to be a missionary of the faith. As a member of the Akatsuki.

Hidan is a very foul-mouthed and disrespectful man; he frequently used profanity and complained towards allies and opponents alike, despite being a "highly religious" person. He rarely used honourifics when speaking, and, even then, usually as a form of sarcasm.
