When UA wasn't full of heros and was still free willed and no villains. Most of the pro heros were still young and even at the age of 3 or 5 years old. Considering that they were still small and needed to learn, there parents dropped them off at preschool and either it could come to crying, laughter or tantrums. They would still be at preschool.

And today you were an unfortunate little bloomer and your mother dropped you off at preschool, and it was the early 2000s.

And you seen various of little kids that in the future will be pro heros and teachers. But unfortunately you spotted a little boy and crying. He wasn't familiar with this place and his name tag sticker said 'Shota Aizawa'. But you looked closer and he had a bowl cut.
