One kinda interesting thing I noticed in the first two chapters here. In chapter 1, Cleo thought back to his resurrection, how Kohaku said she'd give him her life (but it's not like she lost it), and how it's weird he remembers something she would've said when he was supposed to be dead at that point anyway. In this chapter, notice Cleo's hand after the slaver gets Kohaku out of his bag, before he tackles him: it's got a little glowing aura around, sorta like when Kohaku casted magic.
Think maybe something's being set up where she's, like, literally put a part of herself into him (will that mean he can bring her back, but at the cost of his life, or is his life now "okay" since he's been animated and running normally?).
