Background

Chabashira serves as Class D's homeroom teacher at Tokyo Metropolitan Advanced Nurturing High School. She understands the academy's core rules and assessments, and her memories include earlier Class D cohorts being crushed by evaluations, losing large quantities of points, and in some cases dropping out. 10

She views Class D as a group of problematic or flawed students and considers excessive encouragement pointless. Rather than preparing them for the school system, she expects them to learn through the consequences of their own behavior. 10 11

Appearance

Chabashira maintains a consistently cold, professional presentation in the classroom. Her heels are noted for their sharp, resolute sound as she leaves Class D after announcing Sudo's expulsion. 9 45

• Frequently wears an expressionless or cold expression. 9 10 44
• Often stands with her arms crossed while observing students. 10
• Her gaze is described as icy, forceful, and scrutinizing. 9 29 44

Personality

Chabashira is stern, emotionally restrained, and blunt. She delivers school rules and punishments without softening their implications, treating Class D's failures as consequences the students must face themselves. 11 29 30 45

Her apparent indifference extends to withholding information: when confronted over Class D's loss of points, she states that she has no obligation to explain every detail of the school's rules. 29 She frames the academy as an unequal society whose rules must merely appear equal on the surface. 47

Despite this harshness, she shows amusement and possible appreciation when Ayanokoji and Horikita find a way to purchase the point needed to save Sudo. 47

Story Role / Major Arcs

Class D's Initial Point Allocation

Chabashira introduces herself as Class D's homeroom teacher, warns students that they cannot change classes midway, and explains the school's isolated campus and private-point system. She announces that every student has received 100,000 points. 9

Although the class celebrates, she privately expects their irresponsible spending to lead to a harsh lesson. 10 11

Loss of Class Points

After Class D receives no monthly private points, Chabashira reveals that the class has exhausted its initial Class Points. She explains the relationship between Class Points and private points, while criticizing the class for reducing a 1,000-point starting total to zero. 29 30

When Linmu questions why she did not warn them, she refuses responsibility for informing students of every rule. 29

Midterm and Sudo's Expulsion Crisis

Chabashira announces that Sudo is the sole student to fail the midterm, then explains that the passing threshold was 40 points while Sudo scored 39. 44 45 She rejects Hirata's and Kushida's pleas for a second chance, declaring that school rules allow neither makeup exams nor exceptions. 45

On the rooftop, she entertains Ayanokoji's argument that a grade point may be purchased under the school's principle that everything has a price. After Ayanokoji and Horikita pool 100,000 private points, she sells one English point, preventing Sudo's expulsion. 47
