Saeko Busujima

Saeko Busujima (毒島冴子, Busujima Saeko) is a student at Fujimi High School, a member of the survivor group led by Takashi Komuro and the daughter of Master Busujima. Before the apocalypse, she was in her Third year and was also captain of the Kendo Club at Fujimi High School. In the group, Saeko is considered the most reliable of all fighters, and everyone can count on her combat skills to pull them through a tough spot if need be. Like Rei, Saeko is an athletic fighter and talented combat specialist whose forte is in melee attacks. She is one of the reasons why the protagonists have managed to survive as far as they have. At the beginning of the series, she uses a bokken wooden sword that she used to fight "Them" with, but she was later given a sword by Souichiro Takagi to fight "Them"

In A Time in the Universe, she is a main character in the First Arc.

Personality
Saeko Busujima is shown as a kind, caring, strong and reliable woman, pointed to everyone else. She follows her samurai lineage and the bushido code. Her character, behavior and language was shown throughout the series.

However, later on, she has developed sadistic tendencies and explains to the group that she has developed it a long time before the events of the Series. This was due to an incident four years ago when Saeko was attacked by a man on her way home, which forced her to severely injure the man. She realized that she loved inflicting pain and suffering to everyone that tried to attack her or her friends.

Despite her sadistic tendencies, she has proven to be a capable fighter.
