Fate/Motivation (Vergil OC x FateVerse)

2 young boys are stranded in a sea of fire, one child with white hair and blue eyes is holding into a sheathed katana with all of his might, their flame of life is slowly withering until a man in a black suit save them from their doom. Now years later a war will commence for the Holy Grail, but with changes because there will be a storm approaching.

I do not own DMC and Fate they both belong to their respective creators.
