Well, Shiki Ryougi's Mystic Eyes Of Death Perception. Shiki Tohno's reduced his lifespan or something like that, right? That's a weakness that somewhat balances it's use.

Still, excuse this moment of possible noobicity, but what question are you answering specifically? How to counter it? Because if so, MEDP and inmortality both make someone with this kind of Semblance useless in comparison.

MEDP can kill the person with this directly, or "kill" their Semblance right away making it useless.

Against an inmortal that can't die, making it's Aura Null it's useless, as they wouldn't die anyway.
