In the world of ninjas, many things come down to qualifications.
Bloodline, talent, background, and which side you're on.
Uchiha Rikka doesn't care much about any of that.
Whether you're a child who can't even hold a kunai steady or the village's most celebrated prodigy, you can make a wish to her.
But you'd better think one thing through first:
What is it you really want?
Some receive power, some receive opportunities, and some finally realize that the "only way" they once believed in without question isn't the only option after all.
What they do with what they receive is up to the wish-makers themselves.
Rikka wants to see where they'll go.
As for the clan head, the elders, and the Hokage who end up with headaches over it...
They weren't the ones who made the wishes.
