“The last thing I want is for the line of successors to end with you... For the sake of you, Grandfather, and all the others who have wielded Raijinto... I must be prepared to take the lives of my enemies and protect the kingdom. Even if I get caught up in the heat of battle, I will not forget my resolve...”
Shiro is a playable character in Fire Emblem Fates on the Birthright and Revelation paths.
Shiro is the son of Ryoma and the cousin of Kiragi as well as one of the grandchildren of Sumeragi.
In his Paralogue, Shiro departs from his Deeprealm and ends up in a barren desert in the real world. Upon entering, Tarba ambushes him and threatens to kill him if he does not give up his equipment. Shiro refuses and prepares to fight Tarba and his gang.
Fortunately, Ryoma and the Avatar's forces arrive, after receiving word from Shiro's caretakers that he had gone without a trace. Ryoma is upset that Shiro left his Deeprealm but focuses on routing the bandits first. After the battle, Shiro is shocked that he is actually part of the Hoshido royal family, as while growing up, he was never notified of his royal status. Ryoma tells him that it was for his own safety due to the war between Hoshido and Nohr. Despite this, Ryoma allows Shiro to come along so he can learn more, as Shiro admits to Ryoma that he was taught to fight, and not to kill.
