I feel like Sui has completely taken over this manga, he was in the novel, but he is practically the main character in the manga. Not like that is a bad thing, just different.
I like the child-like Sui, but in this chapter its innocence was just translated as annoying incompetence. This is exactly how you ruin a character completely... @Mojo
Well, yes. This is a spin-off that focuses on Sui.
