My second biggest fear after Zanka dying is something happening to Lovely Assistaff, if she gets destroyed I fully believe that Zanka would give up on life, he's extremely attached to her and losing her would break him entirely
you ever consider the fact that assistaff is a blunt, technically non-lethal weapon in her unactivated state… when fighting people, compared to eg. the ripper that would basically kill on hit, even activated assistaff is more suited for inflicting pain rather than killing. hm.
The more we learn about vital instruments and how hard it is to have one the more insane it feels that Zanka bonded with Assistaff in just three days. Boy what do you mean you interlinked your heart and soul with a inanimate object in just 3 days. Whats your problem.
i have noticed something when goka carried away zanka, he took lovely assistaff with him too, he didn't leave her there, for someone who hates givers and by extension vital instruments, he still made sure to take his brother's treasure with him.
