This Corrupt World's "Normal" Is Difficult

At least this much is "normal," is it not?

Elma who was raised in a prison was dangerously granted pardon and released. Though she tries to heed her mother's words to be "normal," while working as a maid in the royal palace, her outlandish abilities and behavior end up shaking it up in its entirety. Successfully carrying out a four person's job in one morning, tea that would taste as if it was blessed by the heavens if she brewed it, dissembling a giant tuna with one stroke of a sword, and even with a surgical procedure more advanced than recovery magic as her forte.
--if not a little dangerous, even this normal is it not?

The curtain opens on a story of a thoughtlessly peerless girl who had intended to be normal.
