RAHHHHH I LOVE SANO
Just saying, Sano would so starve you and then feed you human flesh (he makes sure you know it’s human too) so that he can see how cannibalism breaks your down
He wants to see you try and swallow the flesh, struggling to gag and keep it down despite your conscious fighting you
But you’re so hungry, and you need to eat! Poor Sano is starving you and all you can do is eat what he gives you, doctors orders!
What Sano really wants to see is how sick you get
He wants to see how sick you get from the diseases human carry, from all the holes that develop in your brain after eating someone else’s (true thing that happens btw), he wants to see you vomit what little your guts have left from how disgusting eating flesh is
He wants to see you become even rabid for food, swiping at his hand like an animal just so you can sink your teeth into raw meat like a goddamn dog. He gets a sense of sick joy from observing you and seeing how bloody you get, not like you care being bloody when you haven’t eaten in two weeks
Tbh I have a ton more headcanons about Sano’s medical practices (he’s so done the blinking head experiment)
Like one of these hcs is like Sano has tried using organs (like fucking child organs or animal organs, and I’m not talking like using a pig valve to replace one in your heart I mean like maybe a whole ass spleen of a monkey or smth) and used them to replace perfectly working organs
Sano is mostly a huge brain freak tho, lobotomies, CRT (I believe it’s called that, it’s something hing football players experience from constant reoccurring head trauma and it can really fuck a person up), transplant, straight up just cutting pieces off and poking around in there to see what’ll happen. His goal in life is to rattle your brain and not in the fun way
