Omshan Rekyo - The Japanese Yakuza

Shujhi Taguchi is strangled to death by three of his Amshan Rekyo fellow cult members. Shujhi was so devastated when his friend died that he threatened to leave. Ashahara gets paranoid that Taguchi will go to the authorities and basically rat on him. Many people involved in this story are basically on never ending acid trips. They do LSD. They do meth, they make their own barbituates. It's how breaking bad was conceived.
