Ms Smith

History
Miss (or doctor in formal conversation) Smith was born in Ireland in 1961, and is 57 as of 2018.

She had a mundane childhood and adolescence. She attended Bullshit Catholic in 1979, and was slightly overweight compared to the other students at the time.

After graduating she went on to join a series of militaries and terrorist groups, such as the Irish Republican Army, the Soviet Army during the invasion of Afghanistan, fought on multiple sides of the Yugoslav Wars, in the Somali Civil War, and so on.

It isn't known when, but she attended Trinity Collage in her home country of Ireland at some point, getting her PhD in Biology. She started working at her old school sometime after. She appears to also have some education and training in Catholic theology, as she is a nun and acts nervous about anything that may violate her Christian values. However, she is willing to comply to Principal Anon's request without complaint when the students are involved.

She is a tall and curvy woman with long brown hair, and shares a lot of similarities with Sawako Yamanaka from K-On. Despite her advanced age, she managed to have a solid six-pack of abs by default and there is no evidence that she dyes her hair.
