Background / History

Chabashira enters Class 1-D as its homeroom teacher, distributes the students' school-issued IDs, and explains the S System and monthly point deposits. Her presentation establishes points as the school's central currency. 1

When Kengo Tendo investigates the school's expulsion system and Class D's standing, Chabashira refuses to disclose the information under school regulations. She instead offers to sell the answers for two million points, stating that points can buy anything. She also explains that a student may apply to transfer to another class for twenty million points, while only Class A receives a 100% advancement rate. 2

During Class D lessons, she does not intervene when students talk, use their devices, sleep, or otherwise disrupt class. Kengo interprets her deliberate indifference as evidence that discipline is being evaluated through the school's surveillance and class-point system. 2

After Kengo publicly reveals his findings, Class D demands confirmation from Chabashira. She gives the same response: two million points in exchange for the complete rules. The resulting dispute over pooling points exposes the class's lack of unity. 3

The following day, Class D's argument forces Chabashira to end class early. She states that further updates on the assessment rules will be announced later and leaves the classroom amid the continuing turmoil. 4

Personality
