Sakura has short pink hair cut above her shoulders and pointed dark blue eyes rimmed with notable eyelashes.
At first, Sakura is very hostile towards Class 3-E and attempts to bully them. However, she eventually warms up to them (particularly to Nagisa).
Sakura was bullied at school until she stopped going to classes. After that, she stuck to studying at the cram school where the other kids feared her.
Mistake and Nursery Time
After most of Class 3-E crashed into an old man while freerunning against Karasuma's instructions, the entire class were told to take care of the cram school the old man (named Matsukata) ran. Upon their arrival, the children of the cram school swarmed them but Sakura remained unimpressed. Intending to test their "guts", she ran at Nagisa with a broom only to fall through broken floorboards. Later on, Nagisa attempted to tutor her but she grew impatient as he tried to figure out a way to explain it to her. He then asked her why she didn't attend school and Sakura explained she was bullied, comparing her situation to a cat that had gotten stuck in a tree. Nagisa responded by telling her to think of the ground as the cram school and the top of the tree as her school (meanwhile the cat is rescued by other Class 3-E students). He explained to her that they get their strength from the ground and are looked down on by others even higher but it's after learning the fearfulness of heights that they are able to move around so freely. He then cautioned that they could still forget about the fear of heights and end up falling to the ground again. Sakura looked up at him in amazement and Nagisa offered her the chance to learn at the cram school and set up a "strategy".
During the following two weeks, she studied under Nagisa's tutelage. When Matsukata returned, Sakura arrived and revealed she came second in her class. She followed the strategy Nagisa gave her: to go to school just for the arithmetic test and then make a break for home. Nagisa then instructed her to continue with the "hit and run" tactic to "build her arsenal" for "battles at school". Sakura shyly asked if he'd come back to teach her again to which he agreed, much to her joy.
Sakura has made periodic appearances since. She returns in Chapter 116 along with the rest of the cram school. They visit Class 3-E's restaurant and reveals she asked Nagisa to be her private tutor. When Nagisa mentioned it being a "difficult battle", Sakura noted that they had a "mysterious power" so not to worry.
During Nagisa's final term, he was tutoring Sakura. At the time he was undecided on what his future career should be. Sakura suggested that he become a teacher much like how he was currently tutoring her. If that failed she blushingly added that she could be always be his girlfriend. In another tutoring session Sakura was practicing for a test. Noticing that her concentration was breaking up as she thought of all the bullying she endured, Nagisa helped to calm her down. This effectively confirmed Nagisa's choice to become a teacher like Korosensei.
Later she took the final test in Chapter 163 so she can return as a Sixth grader in Elementary School. Despite her trauma, Nagisa manage to calm her down when she was struggling to keep her mind on the exam while fearing she will be bullied again.
