Asta Black Meteorite Manga Black divider is capable of slicing through devil flesh and potentially human elf the berserk form sees asta lose all sense and therefore he is not in control

Black meteorite couldnt keep up with luck who is objectively slower than elf yuno at this point since asta couldnt keep up with patris light sword judgement asta has full control over his black meteorite and black tornado in a jam so i dont think range has literally ever been an issue for him anywho
