   Summary

   She was never meant to be part of the League, only a controlled asset, a researcher too useful to discard and too dangerous to trust. Assigned to supervise Shigaraki's development under the guise of scientific necessity, she approaches everything with clinical detachment. But between biological anomalies, failed containment, and a boy who shouldn't matter to her calculations, something in her carefully maintained control begins to break.

   or

   Reader is a scientist that works with the Doctor and AFO to create Nomu's. She's unfortunately assigned as Tomura's babysitter and is forced to create what he wants. She also gets wrapped up in the League's shenanigans as well as wrapped in a destructive spiral of something disguised as love.
