Shirou Emiya In Fate/Zero [Miyuverse Shirou]

Miyuverse Shirou Emiya still has to complete his side of the contract in ensuring Miyu's happiness. As Alaya has given him the chance to fulfil the oath he has made, she sends him back to the 4th holy grail war of the world Miyu is sent to as a servant. However it is a time before she will arrive.

Alaya uses the help of another to merge the archer card in Shiro, also remove his tan marks and patch of white hair. It'll help him be at his full potential, comparable to the Heroic Spirit EMIYA, but also with her interference it will give him a boost in strength and speed, making him better than the original.

His goal is to win the Grail war. But to also make sure Irisviel doesn't die. He is promised that even if he fails to win the Grail war but is able to make sure Irisviel remains alive with Kiritsugu then he can still become human and live a human life.
