Something like this does not happen once but thrice, frice, and so on. Basically, all scenes circled by Narukami showed the same thing of him getting killed by Ryu. With the same, betrayed expressions. It was dreadful to watch.
"Stop," said Narukami slowly as he watched himself get pierced in the head with Ryu's hand. Other scenes showed him getting his limbs mutilated before Ryu cut his throat, the head flew off as it landed with a bounce.
"Please, stop," begged Narukami with a low tone as he closed his ears. His eyes were wide yet his pupil was the size of a tip of a pen, shaking.
Cold sweat flowed down his cheek. Although what he was seeing was through a monitor. He could feel the pain but thanks to his abnormal pain tolerance, he could endure them.
The thing he couldn't stand the most was the betrayal that took place. That feeling tore his heart to pieces like a pack of wolves that didn't eat for days and finally found a little lamb.
