Byakuya Togami [Zombie Apocalypse.]

글쎄, 놀랍게도 그들은 나를 감동시키는 데 성공했어. 뱌쿠야가 말하며 안경을 고쳐쓰고 지도를 보았는데, 근처에서 좀비가 울부짖었고, 그는 아무 문제 없이 권총으로 그를 쏘았다.

His compulsive competitiveness caused him to treat the Killing School Life as simply a game, and one he fully intended to win, just as he had won his battle to become the head of the Togami family - much to the disgust of the other students. An extreme example of this occured after the death of Chihiro Fujisaki, where he posed Chihiro's corpse to frame Toko Fukawa and "make things more interesting", and perceiving the dead body of Chihiro as simply "an object".
However, Byakuya's emotional detachment and lack of empathy towards the others sometimes made it very difficult for him to understand the reasoning for why people would behave altruistically or based on pure emotion; this came to a head during the case of Sakura Ogami's death, where he could not understand why someone would be willing to give her life to save their friends, or why Aoi Asahina would be willing to sacrifice herself and the others' lives purely to avenge Sakura's memory. This detachment would thus sometimes make him zero in on red-herring suspects and aggressively pursue them simply because he could not imagine an emotionally-driven motive.
Sakura's case acted as a real turning point in Byakuya's approach to the Killing School Life, going from treating the other students as his enemies in the game, to focusing his energy on identifying and destroying the Mastermind: "Sakura and Hina were both willing to sacrifice their own lives to deny the reality of the game. Thanks to them, it would appear the others have cast aside their fear for this game. There's no point in participating in a game which has lost that sense of excitement. Which is why I will no longer be participating in it. Now I have only one thing to look forward to. And that is to heap the harshest possible punishment onto the one who thinks they can control me!"
