Like the rest of the Hamato family, Atsuko was trained at a young age to defend her Hamato Clan and the world from the Shredder if he was ever to return. Later on, she would give birth and raise her only child, Yoshi. When Yoshi was of a young age, Atsuko had to leave him with Hamato Sho as she had to perform her duty of protecting the Clan. After this, she passed away of unknown reasons and Yoshi never saw her alive again.
