@VanJosh even more so if they judged person from what they can see
this random dude just beheaded a man, killed several others with 1 swing and smashed another to the wall all without giving them any chance to retaliate
and yet "A FAMILIAR USER CANNOT BE STRONG"
i haven't read the novel yet, did the novel explain how a familiar contractor get power from their contracted beast or something (which got dismissed from the manga?)
and that jewel whatsoever would negate the said power?
if not, that's just peak stupidity and lazy writing there
