Four Archfiends

"Four machines created four centuries ago. No one knows how such miraculous things could exist at that time. But, magic is the cause for miracles, so this shouldn't be too out of the ordinary. But still...a single one can very well be a threat to a country. No wonder they're used as seals for the strongest demon."

- Hakase talking about the Four Archfiends Four Archfiends (四魔王, Shimaō), also known as Lords of the Four Realms (四場の主君, Shichō no Shukun), are four ancient machines, created as the final seal for the Grand Demon, doubling as a security measure if someone tried to break the seals. They are located across the four corners of the Pergrande Kingdom, the north, south, east and west.
