"Shirou-sama, I will be frank with you. As you are now, your powers are more than enough for you to enter a magic knights squad. However, while it is possible for you to receive early admission, I would like to recommend you a different path. Right now you, despite being as strong as a magic knight, you are not strong enough to protect yourself from every threat, both inside and outside the kingdom, that comes your way. Your heritage, position, magic energy, and especially your skill set solidifies the fact that too many will want to either get rid of or capture you, and they will not care about any victims they might leave behind. To deal with this you need power, and while I am no expert in weapons I know a thing or two about magic. Thus, I would like to know one thing... will you accept me as your master?"
