Worship Rep-un-kamuy as our Patron God
Rep-un-kamuy is the Ainu god of the sea, sometimes pictured as an orca and sometimes as a carefree young man with a harpoon. The sea offered fishing, whale hunting and trading voyages that the land could not.
In one myth he throws a harpooned whale ashore near a village. Told that the humans butcher it with axes, he laughs and lets them have the meat, until he sees that they cut it with ritual swords in the proper manner.
