I just got teleported into another world As Shirou Emiya's brother?

Asashi Akio...your average teenager...He was bored out of this world so he found happiness in reading VNS and playing games. One of his favorites...Fate Stay Night just released another copy of their famous VNs so, he did what most fans will do, buy the new release. For him, his day was normal, however he did not anticipate what will happen to him soon enough.
