Everything was going well in the morning on the mission.. until that damn quirk hit you, now you had returned to being a little 4 year old girl and even worse, you didn't remember anything after that age, it's like they had rewound your body and mind.. You were beaten by a villain with a gift that makes people's bodies and... memories go back to when you were 4 years old...
