꧁•𓊈~BORROWED TIME-(JJK Y/N X GOJO)~𓊉•꧂

The name of this nearly describes it all. Your curse technique is Clockwork Reversal, or, in short, "Hourglass." It may sound cool and all, but it does more harm to you than anything else. I'll go into detail on what your curse technique is about.

Clockwork Reversal allows the user to rewind the state of anything, living, non-living, or even an area to a past point in time. This applies to both physical and temporal states, which include wound rewinding, material restoration, event undoing.

The cost is measured in lifespan. Each activation takes away time from the user's life, seconds for small wounds, months for grievous injuries, and decades for undoing death. Things like grey hairs, weakened stamina, and accelerated aging occur depending on the amount the user uses it. Excessive use risks sudden cardiac arrest or organ failure. If you're lucky, you can die from old age separately when the overusage of this technique occurs.
