Hmm i think the shrine Issei's father prayed to was the Ise Grand Shrine and thats why he already had the name Ise promised for his child.

Also i think Ise and Tiamat should be connected in a diffrent way like she's nice to Ise but hates Ddraig.

And its kinda was stated that Ise's blood had an effect on Saji's SG when that jewl grew on his hand and the same with gasper when it came to the level of control he had.
