What's even more off to me Kanki still has not a single drop of blood.
Further suspect that his officers will be like fuck that shit and make an escape for him. In that case he will probably be shown vaguely in some panel like Ryofuy making his way outside China borders.
I think the latest chapter is potentially setting up for that exact scenario.
Kanki is accusing Riboku of self-preservation as cowardice, with him using the lives of his underlings as a shield to save his own skin. Of course, for noble reasons, but that's not how Kanki views it.
Kanki is accepting his inevitable doom, and doesn't care nor wants to be protected by others. This is why he made preparations for the Saki to be with the HSU and possibly alerting Maron to abandon the mission, regardless of the threat to his life.
It's possible that his lieutenants disobey his wishes and sacrifice their own lives for his sake, allowing him to escape.
