"To put it simply... honor.
Sera listened in amazement as Mitsui explained his reasons in saving her. Although she had met many different people with many different viewpoints, this was her first time hearing one so noble. That being said, she had never met anyone who still followed the way of the sword. Even the Sword Meisters she met didn't follow that path. It was refreshing to meet someone like this, even if he considered her a child.
"Well, I'm happy you decided to choose helping me over your goals. It was rather kind of you," She began with a soft smile, "But I don't think I'll be seeing my allies as soon as you would think. I don't even know where they went." Sera liked to think of herself as a social butterfly but just like a butterfly, she made sure to never stick close to just one person. Some she couldn't help know all too well, like the children of her parents' best friends. Growing up with that strange lot made it hard to not stop being friends with them. They were very close when they were young but as they grew older, interests and responsibilities split them up. It didn't help that they had strong partnerships of their own, leaving Sera the only one in their old group to not have one. Maybe that's why she tried to avoid them as much as possible.
Growing close to other people outside her niche was also worrisome for the light-haired Weapon. Once people knew who she was, they made such huge assumptions and expectations of what she would be. Some were good, a lot were bad, but she barely lived up to any of them. She quit trying to show who she really was and just made herself as vague as possible to whomever she was speaking to. It was for that reason she had no idea where the Shibusen students would escape to.
A sudden breeze gave Sera the chills and she looked up to see the dark moon high in the sky. Sera remembered the stories her mother told her of the heroic Crona who sacrificed himself to save the world. The memory of her mother tugged at Sera's heart, making her realize just how much she missed her. She wondered where her and dad were.
"I think we should find a place to sleep tonight. We'll look for any sign of Shibusen tomorrow." She stated as she turned back to Mitsui, "Also just to make sure, how old do you think I am?" His previous comments about her being a child were beginning to nag at her.
