Comments of chapter undefined of DxD: The Tale of Blood

i think your 72 pillars are missing some because 54 clans + 10 dukes + bael and belial = 66 pilar devils. so 4 great satans and your oc clan + mammon are not considered devil pillars. and from what i know there are only more than 30 pillar devil clans survive the three way war and civil war. and add the missing ones.
