Ryner is the latest incarnation of a demon/god/insanely powerful thing who has reincarnated as a human thousands of billions of times and therefore died thousands of billions of times. Except he was born human (with magic eyes) and only had the reincarnation thing implanted in him later IT'S COMPLICATED so I don't know how that meshes with your stuff but. Feel free to sense whatever you'd like, and if you want more clarification I can try.

...There was also one time where he may or may not have died and come back to life in this incarnation too I'm... not actually sure about whether he died the full way or not there...
