Lol sry i ment like if she ever met Ise she would be nice to him but still mean to Ddraig.

and who is inshrined there is Amatarasu the sun goddess but there are many more also inshrined there so going there is like asking heaven itself for help or somthing like that.

and it was said in Vol.20 that he went to a shrine to pray but they didnt say what shrine but since Issei's father had already had the name Ise picked out for the child im just speculating that it was the Ise grand shrine but i could be completly wrong
