Sae Chabashira

Sae Chabashira is a Japanese history teacher and the homeroom teacher of class 1-D.

Appearance
Sae Chabashira is a young adult woman with a well-endowed voluptuous body and long brown hair that is tied in a pony tail with brown eyes. She is mostly seen with a serious expression on her face though it does change into a smile on occasion.

Personality
As a teacher, she is very serious in her job as she makes sure to teach the class about their subject. She follows the school rules to the letter as shown when she bluntly told Ken Sudō he would be expelled from the school for failing the test.

She appears to have a sadistic side as she called her students disappointing as she informed the students that they wouldn't receive points after they blew through them in a month and took joy in their anguish. She also demanded a large sum of points from Kiyotaka to stop Sudō from being expelled, she did this because she knew that he didn't have the amount to pay for such a thing.

Despite that, she shows some leniency in teaching the class as while she was teaching the students were either sleeping or playing their phones. She was also willing to rescind Sudō's expulsion after Kiyotaka and Suzune paid her to halt their classmates' fate.

She seems to have taken an interest in Suzune and Kiyotaka as their selfless deed was something she had never seen at the school. She appears to recognizes the depths of Kiyotaka's intelligence and figure out that he was hiding his talents on purpose as he wouldn't be in the lowest ranking class if he was that amazing.

According to herself, she has a life of regrets meaning there were some terrible events that transpired some time ago.

She has been seen smoking a cigarette when by herself.
