Nico Di Angelo, Assistant of Ironman

I've seen some of PJO and Avengers crossovers where Percy is Tony's assistant, but I was like, what if it was Nico? Because I love Nico and can never find enough fanfics about him.

Pjo is aged up several years, they're adults now.

Nico was annoyed. This isn't uncommon, seeing as he has to put up with annoying friends and terrified campers on a daily basis. However, neither of those were the reason for his annoyance, which was unusual. You see, after the Seven all went on with their lives, as one does, Nico didn't know what in Zeus's nose hair to do with his life. Sure, still had friends at Camp, but they had lives and goals. And yes, there's Will, but he can't just have him as his only reason to live, plus he also has a life and a goal as to what to do with it (Medical School). Nico does not. Other than his new job, he has no idea what to do with his life. However, after a video of a camper fighting a hellhound is released online, his boss and his friends start getting too nosy for their own good. Will Nico be able to keep his secret from the government, or will it all go wrong?

Tony is interested. It's not very often someone can tell him what to do, and he ACTUALLY does it. So yes, he was very interested in his new assistant Pepper hired. What is it that makes Nico Di Angelo so special that Tony freaking Stark listens to him? And why does he have a sword?!
