The Master Dragon Emperor (FGOxHsDxD Fanfic)

Zelretch being bored of always tossing multiple Shirous in different timelines or dimensions decided to switch to another person to "help" and it just so happens that he apparently, not coincidentally found a perfect test subject to "help". Follow Issei Hyoudou's life as he adjusts to a secret society with devils, angels, Gods and other different mythological beings while having a weapon which can say "F you" to a God and at the same time a Master of multiple servants as his "harem"....or not?

Note: First story I ever wrote in my life so I appreciate other authors or readers' insights and opinions on my story....Please less flames and more flowers please...And I usually right what is on my mind and also write for fun but still research important things like servant backgrounds, pasts, etc.
