The Shitenno are the Four Kings of Heaven.
They are:
Jikoku (
Indian-
Dhritarashtra): Protector of the East. He holds a sword and a little
ossuary.
Zocho (
Indian-
Virudhaka): Protector of the South. He fights
evil and does
good, and holds a sword and a shield.
Komoku (Indian-
Virupaksha): Protector of the West. He holds
a paint-brush or a spear in his hand, while the other hand is on his hip or holds the sheath of his sword.
Bishamon (Indian-
Vaisravana or
Vaisramana): Protector of the North. He holds a sceptre and a little ossuary shaped like a
pagoda.
They live in the slopes of mount Sumeru, on the top of which dwells Taishuku-ten, whose vassals they are.
