I'm a Healer, But...

this is not my story all rights go to yellowleader on AO3

Magic always comes with a price, which is why superpowers are the best evolution since bipedalism, and of all powers, healing is one of the rarest- and thus, healers are quickly stolen away by heroes the moment their powers are discovered. Which is why the SBI, semi-immortal villains who can only die by injury, want their hands on one. So when a weird, loud, pushy teen shows up and offers to trade them a powerful healer in exchange for the smallest, simplest favor... how could they say no? Too bad this won't be as easy as they think.
