Sachiko is childish. She will stick her tongue out if a camera is pointed at her. If she witnesses a murder, she will have a mental breakdown. When she has recovered, her mind will create a "reality" and she will act as if nothing is wrong whatever atmosphere there is. If she sees people dead, her reality will be shattered, and her mind will break.
Sachiko normally enters the School grounds at around 7:25 AM or as she always wakes up late. Once she has arrived at School, she goes to her locker and searches for any lost sweets until 7:35 AM. She will then go to the light music club and practice on her own until 8:00 AM.
At 8:05 AM, Sachiko walks into Classroom 1-2 and doodles in her sketch book. She starts her morning classes at 8:30 AM, and leaves to sit underneath the Sakura Tree at 1:00 PM.
Sachiko walks to class again at 1:30 PM and finishes her afternoon classes at 3:30 PM. Afterwards, she heads to the Light Music club and stays there until 5:45 PM practicing half the time and playing hide and seek the second half. She then walks home.
