Ayase was a clever and intelligent person as an Academy student. This caused people to stay away from her, thinking that she's too bossy and boastful. One time, she found a box of scrolls, right outside the Hokage's office. She then went home with two scrolls and began to study one of it. This led her into gaining full chakra control, being able to use a partial form of the Yin Seal. The other scroll was about the knowledge of poisons and tools that can be used for battling stronger opponents. The next day, she quickly returned the scrolls back to the office, only to find that the box was with Sakura Haruno, who is Ayase's Academy teacher. Ayase was able to return the scrolls, however, Sakura became a little mad at her for "stealing" them.
