Do that.I always liked situation when something average at best/Evangelion,SAO,etc/ is turned into something really good.
It remind me Halkenginia online by Trigerhappy/SAO and ZnT/ ,unfortunatelly dead as dodo.I hope,that your story would live.
Great story.Mythos are good,but average SM,WF,SAO or Evangelion are otheir own,in my opinion,rather ...average.
But you mixed them all,and turned into good story.Let Nurgle and Cthutu bless your works !
