In a 'Hidan Sacrifices OC' fanfiction, the OC could be a sacrifice to stop some greater evil. Hidan, believing in his twisted way that sacrifice is the answer, chooses the OC. The OC might be an innocent bystander or someone who was in the wrong place at the wrong time. However, the sacrifice could have unforeseen consequences. Maybe it angers other characters in the Naruto universe who then seek revenge on Hidan for his cruel act.
The OC could be an outcast in the ninja world. They don't belong to any major clan and are constantly on the move. Hidan might see this OC as an easy target. The OC might have some unique skills, like being able to communicate with animals, but these skills are not enough to protect them from Hidan when he decides to sacrifice them for his own dark purposes.
Well, it could be about an original character who gets caught up in Hidan's sacrificial rituals. Maybe the OC is a new recruit in the Akatsuki and Hidan decides to use them for his Jashin worship. The OC might have some special power or knowledge that either makes them a prime sacrifice or a target for Hidan's wrath.
Well, if Hidan mistakes an OC (original character) as a Jashin fan, there could be some wild consequences. He might try to involve the OC in his Jashin - related rituals. Since Hidan is extremely devoted to Jashin, he could see this as an opportunity to either convert the OC or use them as a sacrifice. It would be a really chaotic situation for the OC as Hidan is not one to be reasoned with easily when it comes to his beliefs.
Well, it could be about Naruto having to face Hidan's unique immortality jutsu. Maybe Naruto tries to find a way to defeat Hidan without using his normal brute force. He might study Hidan's religious beliefs related to his jutsu and use that knowledge against him.
A possible main character could be an OC who is a young and inexperienced shinobi. This shinobi accidentally stumbles upon Hidan's secret sacrificial site. Hidan, seeing this as an opportunity sent by Jashin, decides to make the shinobi his sacrifice. The young shinobi then has to quickly grow and learn to use their latent ninja skills to survive the encounter with Hidan and potentially expose his actions to the ninja world.

One possible plot development could be that Sasuke is initially in a situation where he is facing an enemy he can't defeat alone. Naruto steps in and gives his life to save Sasuke. This would lead to Sasuke being filled with guilt and a new sense of purpose. He might vow to carry on Naruto's will, perhaps trying to bring peace to the ninja world in Naruto's name. Sasuke could also start to question his own actions that led to Naruto having to sacrifice himself, and he may become more empathetic towards others as a result.
In the fanfiction, Naruto might sacrifice himself for Sakura in a more selfless act of love. For example, if Sakura is afflicted by a deadly curse and the only way to break it is for someone to transfer all their life energy to her.
