No offense but that doesn't help in any way...
Elder son of what, who, how does that imply power of reality or anything that can be built upon to an understanding of classification
I am aware that in the Narutoverse it is a form of religion that Hidan's character worships and gains his power through,
but given that in none of the manga fights (as I dont watch all the anime ep), he showed no ability to regenerate anything and that
his character hasn't been in action since the fight with Shikamaru... him (Jashin) being an elder son ....helps the conversation in no way...
If you as a person would like to research Jashin more and bring that information to this thread ,
I atleast would be willing to give you a rep + point for it but you would need to site your sources, and I'm saying you as person as I really have little interest in the character other then what pertains to the question posted by orchimaruofthesound...
I am aware that Kishi uses alot of his cultural heritage as source information and subject matter within his Narutoverse (ie: Kamu,Amaterasu, etc).
