There are many different versions of Shirou Emiya, there are many versions that are not even an Emiya. One of them is a Shirou that is so different from all others that you could call him unique. He was a Shirou that grew up normally. Or, as normally as one with the surname Hakurei could get. Sadly, walking plot device Zelretch deigned him worthy of assistance back into the path of suffering. Not that he wanted to, but what can you do when the Gap Youkai herself also pitched in? (For the record, this Shirou is not Emiya Shirou. You could call this an OC with the name Shirou and the family name Hakurei instead. Thus, no sword/sword origin and element distortion to be found here)
Fairly good for a nasuverse fanfic. The DS is helpful for his lack of strength and aptitude from the original Shirou. Harem the way for this and cool to see the changing fate lies before him and for everyone he dear hold.
