Name Origin
Doya is short for Doyagari, the name of the tribe he hails from, which is also derived from "yadokari" (hermit crab)

Doya Osa can be translated as "Doya chief"

Origin
The Doyagari Tribe Members seem to be based off of the Sazae-oni, a sea dwelling demon in Japanese folklore that is known for its turban shaped shell. Coincidentally, the Doyagari Tribe Members also have a shell resembling a turban.
