(Thanks! And yeah, there's a theory that Hidan invented Jashinism and Jashin is his split personality, which is the voodoo-doll skeleton he turns into. Which does explain why you never hear about any other followers and why the religion isn't mentioned by anyone besides him.)
Hidan's eyes were closed as he felt the bliss come over him. He was panting slightly, and then the hurt faded. He could feel himself being taken away, floating. It had been a while since he had felt this. He felt calm, serene.
Hidan opened his violet eyes and he discovered he had been robed in black. The same robes everyone around was wearing. He watched, on the side, like everyone else. He had not been to Jashin in a while. He did not get many converts, only sacrifices. But he enjoyed the feeling. He still felt the pleasure surging up and down his body. He had to lean against the wall to hold himself up.
Jashin sat on top of a throne made of skulls and broken bones. He looked at her emotionlessly. His dark eyes unreadable as he stood and finally made his way over to her. He looked like a skeleton, almost like a voodoo doll. He approached her. Oddly, he was beautiful, in a weird way. He approached and bowed to her. Then he tilted his head to the side, watching her.
