Sakura Kiyashiki

Sakura is a young girl that Nagisa meets when Class 3-E help out at Wakaba Park's nursery after causing the principle to break his leg.

Appearance
Sakura has short hair cut above her shoulders and pointed eyes rimmed with notable eyelashes.

Personality
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).

History
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 was No. 2 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.

School Festival Arc
Sakura 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.

Nagisa Shiota
Upon meeting Nagisa, Sakura tried to attack him with a broom only to fall through the broken floorboards. Nevertheless, Nagisa still tried to tutor her and advised her on how to deal with her bullies. He regularly tutors her and Sakura seems to have developed a crush on him.

Matsukata
