From Chapter 23, Tei : "It makes me think of Chase...He looked to me more than he did our father. I wonder how he's been doing...How nice it would be to hear word of them."
He said THEM, meaning Chase and their father, right ? So Tei's dad is still alive.
I'm shocked to know that little Shuraka killed his father. And Nashid said he did it effortlessly. Wow he must be very powerful (≧∀≦)
