The Mikado Tribe and the Izana Tribe

From Yo-kai Watch 4(++), it has been revealed that the previous 'King (Enma) Tribe' was known by the old name 'Mikado Tribe' (symbol mark: purple sun). Furthermore, the existence of the 'Izana Tribe' (symbol mark: navy blue crescent moon), which is in a rival relationship with the Mikado Tribe, has also been revealed. Note that in Puni Puni, both the Mikado Tribe and Izana Tribe are treated as the 'Enma Tribe' (symbol mark: the character for King). Currently, the Yo-kai classified as the Mikado Tribe are all Yo-kai of the Enma lineage (e.g., Enma Kōen (Great King Enma), Enma Gōen (Previous Great King Enma), etc.). Those corresponding to the Izana Tribe are the Serpent King Kaira himself and all his derivatives, as well as Meleque. Those who wield the power of the King but do not fall under either the Mikado or Izana tribes are treated as 'Enma Tribe' or other species as is (e.g., Fudō Myōō [Kenbu Mashin], Rinne [Onnen Tribe], etc.). As for Jaen... it will be treated as a special case, a descendant who inherited blood from both the Mikado and Izana tribes, thus belonging to neither exclusively.
