How come when kids grow a little bigger and stronger than other kids, they hurt the littler and weaker ones?

— Sakura confiding to Nagisa Shiota about her getting bullied

Sakura Kiyashiki (鬼屋敷 さくら, Kiyashiki Sakura) is a young girl that Nagisa Shiota meets when Class 3-E is forced to help out at Wakaba Park's nursery.


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 frequently attempts to harass them; this behavior stemmed from the fact that she was bullied herself.

Once Nagisa Shiota reassured her, she eventually warmed up to Class 3-E and she has developed a crush on Nagisa.


Sakura was frequently bullied at school until she stopped going to classes. As a result of her harassment, she stuck to studying at the cram school where the other kids feared her.


Mistake and Nursery Time[]

After most of Class 3-E injured an old man while freelancing against Tadaomi Karasuma's instructions, the entire class was 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 Shiota 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 the material. He then asked her why she didn't attend school, to which Sakura confided 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; they get their strength from the ground and are looked down on by others even higher, but it is after learning the fearfulness of heights that they are able to move around so freely. He also 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.

Later appearances[]

Sakura has made periodic appearances since and 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 Shiota 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 managed to calm her down when she was struggling to keep her mind on the exam while fearing she will be bullied again.


Arithmetic: Sakura has a decent understanding of arithmetic, scoring 2nd in her class after receiving some early tutelage from Nagisa Shiota.
