So I was playing Chapter 6 on hard mode. More specifically it was H6-5 and when I couldn't find the enemy. I looked up and noticed this enemy up there and he was unable to be attacked. After leaving and trying again I was able to beat the stage but I thought I would post this because I have not seen anyone else post it or have the same problem. Is this a glitch or is this random Soul Reaper just Shinji in disguise?
