Chiho is a mature looking girl with long, black hair, gray eyes and a slender yet curvaceous figure with large breasts. Her three sizes are B91/W60/H89.
Chiho wears her school's standard uniform for girls, which is a dark blue, long-sleeved sailor fuku, deep pink skirt with white ruffles on the inside. She also wears red framed glasses.
Chiho is a very calm and calculating girl, as shown when HOMRA took over their school and she told the students to not fight back since it meant fewer casualties and the members would leave sooner. She also cares for all of the students, seen as she is trying to keep everyone calm while comforting her friend who broke down in tears when they found out they might die no matter what happens.
Chiho is approached by Yashiro Isana and two other "transfer" students while looking at documents in the student council's office. They ask if she remembers seeing the white-haired student during the night of December 7, though she states that she does not, as she was busy dragging Sōta Mishina from the clock tower at the time, who ask for records of the night of December 7. Sakura Asama gives them a newspaper detailing the night. Chiho overhears Yashiro sighing about not being in any of the photos and tells him to ask people from the student newspaper instead. She then adds to them that they should not be dressed in "outrageous" clothes while on campus and that one of them, Kuroh Yatogami, should put away his "prop" sword.
Days later, members of HOMRA intrude upon the school and successfully gain control of the area. Afterwards, they begin interrogating the students about Yashiro Isana. Chiho and Sakura patrol the hallways where they discover that a group of the Red Clansmen are becoming violent with the students, forcing Chiho to raise her voice against them. She explains to Sakura that they must put their classmates' safety above all else.
- The name Chiho means "thousand" (千) (chi) and "grain" (穂) (ho).
