In Inazuma we know that Orobashi was an Archon that created the island of Watatsumi for his people. But Watatsumi is actually part of Japanese folklore.
The story is of Urashima Tarou and is very famous over there. The story is pretty simple. Tarou is a fisherman who saves a turtle from his net. The next day a woman on a boat asks if he would escort her home and he obliges. It turns out she was the turtle. She is also the daughter of Watatsumi which means Sea god who is a big water dragon. (based on the Chinese story about the nine children of the dragon king) He spends some time with her and she gives him a box called the katami no hako but tells him never to open it. Eventually Tarou goes home but finds out that time passed differently and now it's been 700 years and everybody he knew is dead. He forgets about the box and when he opens it all 700 years flood back into him aging him into an old man. In some versions he ends up becoming a kami and reunites with her.
Orobashi is a big snake and with his association to Watatsumi you could make the connection with water dragon. So could that mean that Otohime his daughter and her possible husband Tarou (who ends up becoming a crane) will appear in the future? Could they want revenge against Ei? Could they have already attacked Ei for revenge and gotten defeated but not killed and finishing them off will play out in a future event?
