She keeps her distance emotionally to stay objective, rarely revealing her feelings or personal past while taking charge during investigations. Byakuya Togami: Arrogant, cold, and intensely elitist. He views the survival game as a high-stakes match to be won, treating others as intellectually inferior and openly expressing disdain for teamwork.

He suffers from a severe inferiority complex over physical weakness and constantly apologizes for even minor inconveniences (e.g., "I-I'm so sorry!").
