Chabashira

Biodata

History

Chabashira introduces herself to the incoming Class D and explains the school's special system. When the class receives no monthly private points, she tells the students that poor discipline has reduced their class points to zero. She also warns them that failing a subject on the midterm or final exams means immediate expulsion 2 11.

She summons Hikigaya Hachiman and Ayanokoji Kiyotaka during Horikita Suzune's protest over her Class D placement. Chabashira identifies the two boys as potential keys to the class climbing the ranks, though Hikigaya later interprets the meeting as an attempt to spur Horikita into action 12 14 15. Ayanokoji subsequently says that Chabashira threatened him into helping with class matters 164.

Chabashira administers later special exams and explains their rules, including the paired final exam and the mixed-grade training camp 121 125 173. After Ayanokoji and Sakayanagi raise concerns about Acting Chairman Tsukishiro's interference in the year-end exam, she agrees to help and keep their discussion confidential 254.
