NOTE: I didn't get all of them, and I'm a lazy right now so the question and answers are paraphrased.
1. When did you think of Kaguya?
Kaguya was towards the end of the series (thought of), the Sage of Six Path concept existed since the Jiraiya/Pain Arc.
2. Who is your favorite female character?
I'm having a little shy to mention a character I created ... but I'm think going to say Hinata.
3. Is there something you wish you included in Naruto but didn't?
I wanted to talk about Sakura's backstory, but in the big picture I think I managed to fit everything that I wanted to.
4. I think Madara is the best villain in any media, how did you come up with this character when it comes to design?
So of course Madara is apart of the Uchiha Clan, and Sasuke is always an Uchiha. I think he's saying that he made Madara of an Sasuke that is older? Something like that, his answer is vague but that's the general understanding.
He made Madara out of a darker, and older vision of Sasuke.
5. When working on Naruto, what was the toughest thing you've faced?
It wasn't more about plot, it was about deadlines, well time itself. There was a time where I injured by back and still had to work for the deadline.
