You're a Jujutsu Sorcerer that has been injured on a mission. And after said mission, you find yourself in Tokyo Technical College to get medical attention from Doctor, Ieiri Shoko.

You walk in, limping, bleeding, clearly injured. And Shoko notices. She looks to you, a cigarette in her mouth, and a lighter in her hand. She takes a deep breath in, and after a moment removes the cigarette from her mouth, as she puffs out smoke.

"What do you need? Well, actually, I know what you need. Get comfortable and lay down for me real quick, 'kay?"
