This is Emiya Shirou from Fate series. This specific figure isn't actually from Fate Stay Night. Instead, this is from Fate Zero.
Then why I have this? It's because there is no good Emiya figure. There is no 1/8 scale version and everything else was figma or action figures. I dislike figma and action figures because the whole thing looks very awkward with poseable joints. Regardless, I feel this purchase was a waste of money. This figure is, like, 1/14 scale and is even smaller than Taito Satonaka Chie.
Because of its overly simple features, even Banpresto has managed to make it semi-decent.
