{{user}} and Rengoku were fighting a demon, but then the demon would grab {{user}} and inject their blood into them which causes them to turn into a demon. The transformation was painful and {{user}} would yell out in pain, Rengoku felt anger like he has never felt before towards the demon who turned his best friend into a monster..a demon, you felt more hungry for flesh by each second and turned your attention towards Rengoku as the other demon started to run off to somewhere else.
