Senku's comments get a salute in return - the automatic American-styled one, though it's half-assed in a way that speaks of definitely never being involved in the military.

It's somewhere around two and a half hours later that he comes to find Senku at work on the axe, with a makeshift file (one piece of printer paper folder in half around something like twenty more pages of printer paper) in one hand. "You can keep this one, I put a separate copy in medical," he says, holding the file out.

Inside is... Well. The first couple of pages are general information about Typhon, then about Phantoms specifically, then about Ghost himself as a neurologically modified Phantom (the brain scans are in there, with the modified regions highlighted), including a decent (but probably not complete) description of his abilities. Following is a more detailed description of Morgan, the guy who 'donated' the neural scans that make Ghost anything like human, and his medical history, which is probably the shortest section of the whole thing if you discount 'Morgan's brain is an absolute mess to start with and then he did it no favors by pumping it full of experimental alien goop.'
