Foreign Interference

As an exhausting week of a volleyball training camp was wrapping up for the Karasuno boys, a new ally was flying in. How will the boys react when faced by a new, yet to be identified individual?

This is a Haikyuu!! reader-insert fanfic. I haven't decided If there will be any type of relationship in this, yet. Maybe I could do branches? I don't know. I'll decide later! ;P

I DO NOT OWN HAIKYUU!! None of the characters in this work are mine (aside from the obvious reader character)!
