The Four Deva Kings are four gods, each of whom watches over one cardinal direction of the world. The Four Heavenly Kings are said to currently live on the lower slopes of Mount Sumeru, which is the lowest of the six worlds of the gods. It is a realm that is closest to the land of mortals and watches them closely. The four gods; Tamon-ten of the North, Zōjō-ten of the South, Jikoku-ten of the East, and Kōmoku-ten of the West act as guardians to the human world. The Deva are the protectors of the world and fighters of evil, each able to command a legion of supernatural creatures to protect the Dharma, or natural law of the world. The four as said to act independently, diverting their gaze away from each other but when they come together evil falls in their wake. The Four Deva Kings go themselves every thousand of years to see how virtue and morality are faring in the world of men, incarnating themselves in mortal flesh. Since the creation of their being they have never known more than one of the other four kings, as their gaze can only see from left to right but not behind them. For the first time in history the four gods in mortal form have discovered the existence of each other and banded together under a common goal. They are also vowed to protect the Buddha, the Dharma, and the kind hearted from danger.

Tamon-ten is the guardian of the north, one who protects Buddha and his followers. His name means "listening to many teachings" and he is associated with the element of earth.

Zōjō-ten is the protector of the south, one who protects Buddha and his followers. His name means “He who enlarges” or “Patron of Growth” and he is associated with the element of fire.

Jikoku-ten is the ruler of the east, one who protects Buddha and his followers. His name means "He who maintains the state" or “Watcher of the Lands” and he is associated with the element of wind.

Kōmoku-ten is the watcher of the west, one who protects Buddha and his followers. Its followers are the Nāga. His name means 'He who sees all' and he is associated with the element of water.

Hogasha are the heavenly kings sword, while the last Tengu acts as their shield. The two operate in coherence as one force to protect the world from both the forces of good and evil. No one force may grow to over power the other, and Hogasha maintains that balance. Their intervention is just, and their ideals pure. The guardians Hogasha are themselves above those who inhabit the earth. They administer judgement, jury what must be interpreted, and carry out sentences within their means. Occupied by the greatest mortals of their generation, Hogasha is lead into battle by none other than the last Tengu, Hinote Shin. Their mark is crimson, their cloak bearing black clouds, a symbol stolen from the villains of another time. When acting they move in pairs, though each members assists the others. Their strength lies in their collective consciousness, strung together by Hinote Shin. When facing Hogasha, there is truly no hope for victory. To face Hogasha is to face the worlds strongest. Here is where they reside, Mount Sumeru.
