This is a challenge for anyone that has read the Darkness series by Harry Turtledove. I want to see a crossover with Naruto for it. You can have him attached with any nation you wish or have him as a mercenary. He can be native born or somehow ended up there for one reason or another. It does need to start from the first book "Into the Darkness" and end at "Out of the Darkness". As for pairings there are plenty of female characters you can pair him with. I look forward to seeing what people come up with from this challenge.
