Well im already used to his power of “death”
Ive seen tsukihime with shiki tohno’s power to cut everything and ”kill” anything
Just percieve his power as “ending existances ability to function” rather than just “ending life”
If it exists and is working as intended, then he can make it stop working as intended yet still keep it existing.
Which means stuff like robots, zombies, rocks, oceans and mountains would bend to his will like hes speaking the words of the almighty.
