UA has a new teacher. Enter Amy Laidlaw. A Marine in the Anti Quirk Combat Containment Unit 107th Tactical division. During an op gone wrong on a raid on a human trafficking ring, Amy in the Hospital is hand picked by principal Nezu to join their staff as a new teacher and is given reign over 1A. Amy herself is a 97 year old stuck as a 17 year old, and born during the dawn of Quirks with the quirk of Biological immortality. Amy thinks this will be a normal job, but as she'll find out, it's anything but.
