Crossover: The Hardcore Head Nurse

One day, after working late into the night, a certain trainee nurse became Florence Nightingale. Yes, the historical [Lady with the Lamp], Florence Nightingale. But this "angel" seemed a little different from the one she'd seen in her textbooks... "Sir, you need treatment." As she spoke, she pulled out a scalpel. "There's no need to fear dry eyes. We just have to remove them." A certain Erasure Hero: ... "Sir, you need treatment." As she spoke, she pulled out a gun. "There's no need to worry about having a problem in your head. We just have to blow it off." A certain mastermind behind the League of Villains: ... Although her patients refused to cooperate, their injuries weren't serious, so she simply "treated them by force" until they recovered. But in Yokohama, she encountered a walking roll of bandages... "Sir, you need treatment!!!" The head nurse, spurred on by the smell of blood coming from the boy, brought out all kinds of surgical tools. "Are your eyes injured? That's fine, I'll just remove them! Is your neck injured? That's fine, I'll just cut it off! Is your arm injured, too? That's fine, I'll just saw it off!" A certain black-haired boy: ... Would you believe me if I said I wasn't hurt? The blurb will be changed because of the Little Hero incident. (Keeping the original blurb for now; the main idea is unchanged.) (Because a major plot point of a fellow author's work was plagiarized, and the plagiarist shamelessly pretended to be innocent, I'm starting to keep records of my upcoming story ideas from today on. I can't remember the exact date, so let's start from today. Written on 2020/05/18) Theme: Pursuit and being pursued
