Both the Seventy-two Pillars Demon and the Tarot Card are regarded as western mysticism, and the Tarot Card is considered as a masterpiece of mysticism, which is equivalent to the Western Book of Changes, so it is more capable and repetitive than numbers.
It is understandable that Mihayou concentrated his resources on a few 22 big Akana cards with rich meanings. This also explains why there are only three demons in Mond's history.
Dika Rabin, the God of Tornado, Andrius, boreas and Barbatos, the God of Freedom.
It is known that Tevalin Devalin, the Dragon of Dongfeng, has the power of a fiend, but he has no name of a fiend. When the guardian power is exhausted due to corrosion, it is weaker than the fiend (that is, the level of BOSS this week). After getting rid of corrosion, it needs Barbatos's careful care.
Obviously, the families of the Seven Gods are fixed, that is, they are not demons and are not within the seventy-two pillars, which can be confirmed by the dragon king rock element Azdaha of Long Ruotuo.
The easiest way to judge the seventy-two pillars is to see whether its name comes from or is changed from the seventy-two pillars in reality. For example, Andrius is a powerful fiend.
But when a wisp of ghost can't stay and become the home of Fengshen, it is not qualified to be called Andrius, but Borias (Borias itself is the god of the north wind in Greek mythology). Of course, it may be that Andrius's ghost is sleeping under the care of Fengshen.
