I would say the main character of JoJolion. (his name is actually a spoiler)

Not to spoil things, but before he lost his memory he was a nautical surgeon who used his Stand to perform life-saving surgeries at sea and even after he lost his memories he's trying to find a Rokakaka fruit to save his mother.

He saved a lady trapped in a bathroom (Which is the first Stand fight, actually), so you know he's a true gentleman.
