Nagayama, Toki

永山朱鷺

She sports two distinct hairstyles: one with her hair down during the survival game, and another with it tied in a ponytail. In her long-haired appearance, she can be recognized by how evenly her hair falls.
Within the Survival Game, she belonged to the Cafe Faction and managed the team's communications. She discloses that while she is proficient with computers, she lacks athletic strength.
During the Survival Game, Tanaka invited her on a date. After accepting, it is presumed that they have become Class 2-C's second official couple. Manga clues suggest the pair may intend to graduate and enter the same university.
