'S not like anyone knew about us back then. Most people couldn't see us before...

(Hizen isn't without understanding. If anything, he understands his past situations very well. Ryouma didn't know his sword was aware when he passed it on. Izou didn't know he was never really alone when he carried his sword at his side. Takechi had no way of knowing when he threw away Izou, he threw away two souls. It's why instead of holding a grudge, he carries grief instead and anxiety instead. )

And now's just the same like before. Only difference is people can see us now.

(Being summoned after centuries of nothingness. The sudden sense of being aware and in the world again is the same as before. Feeling the weight of his new humanity on a new form was different, though. This time around is different from the last but--)

I'm a sword. (Not a real human.) I do what I'm s'posed to do.

(And if humans want him to fight, he will.)
