Prologue (Edited)

I don't know why I'm writing this story so yeah.
Inspired by Fate DXD though it's more like that fanfiction story where the main character is either Harry Potter or a adopted father of Harry Potter

Post-Ordeal Call
Sometime after the events of Ordeal Call, Novum Chaldea received a signal that seems to be from another world. During this time, the Last Master of Humanity got captured and caused the resident to be worried.
This incident have created a butterfly effect that could potentially caused an anomaly among the world
