Thanks probably to several friends getting sick and investigating themselves (and a few... "acquaintances" at best looking at you Mukuro), Shouichi is going to help however he can to find out information. He's a scientist of a kind, but his field is engineering and he is not quite as awesome as Tony, so he has NO medical help.

He can use his Sun flames to help heal people a little, but I think he'd likely only do that in a dire straight. Otherwise, you have a hacker and a quick mind to help out?
