What it means to be an Uzumaki (смешанная)

He knows his name, Uzumaki Naruto, but what does it mean? Where does Uzumaki come from? Is that really even his name? It can’t be a standard name they give orphans, because even when he still stayed in the orphanage, he was the only one with that name. Plenty of kids had no last name at all, which makes it more believable that Uzumaki is his real family name.
But what does that mean? Who are the Uzumaki? Is he the only one left? How can he find out? Were his family shinobi? Merchants? Regular civilians?
He is determined to find out.
...
And it kind of spirals from there in ways he never could have imagined. Who knew that posing a simple question would change his life zo dramatically?
