Chitose is a Second Year student at Fujou High, the 15th Student Council President. Chitose is best friend with Roka Shibasaki, the younger sister of Chitose's Older Sister, and the rival of Tama Sakai. According to Ataru Kawahara, Chitose is literally the Queen of the school because both teachers and students bow down to her. Ataru also mentioned that Chitose caused gangs to go into hiding. Chitose is also the co-founder of the Game Creation Club (Temp) alongside with Roka. Chitose element is "Earth", and her main combat method includes punching her opponent with sand on her fist from making sand castle, throwing dirt at them, or digging traps. Chitose has a habit of burying her victims up to the neck.
Chitose have shown to be quite mean at times, abusing her student body president for her own game, threatening to bury people up to their neck, and force people to do thing they wouldn't do. Although, Chitose shows a kinder side towards Roka Shibasaki since she was the first friend Chitose ever made and taught her to be brave. Chitose shown to have good terms with other members of the Fake Game Creation Club, expect for Kenji since Chitose treat him very badly, saying he has foot fetish while rubbing her feet in his face. Even though she treat him badly, Chitose still cares about Kenji enough to try to help him when he is in a pinch and teach him some pointers to be the top delinquent, but leave the rest for him to figure out.
Chitose wasn't always mean and bossy, as when she was five years old, Chitose was quite timid and shy that Kenji couldn't believe Chitose was like that. Chitose didn't had many friends since she spend most of her time playing in the sand to make the ultimate sand castle and was considered a cry baby. This all change when Chitose met Roka and Tama, learning to be more tough in order to keep up with them and to protect Roka from bully or people who been to mean to her as Roka did for her.
When Chitose was four years old, Chitose would spend all her days playing in the sand box alone, which worried Chitose's Older Sister as she feard that Chitose wouldn't make any friends the way she act. Chitose's sister hired a younger Tama Sakai to break her sand castle and be friends with Chitose which backfire as Tama is not interested in becoming friend with Chitose since Tama have tons of friends. When all hope seem lost, a younger Roka Shibasaki appeared and wanted to play in the sand box, but instead of playing with Chitose, Roka ended up playing by herself by digging a hole and put her head in it. When Chitose's sister begged Chitose to stop playing in the sand and make friends, Chitose revealed that the reason she was playing in the sand so she could make the ultimate sand castle, surprising her sister since she thought the reason Chitose didn't play with anyone because she was either shy or physically sick like her. Chitose sister came to term with Chitose and let her play until Tama came and destroyed her sand castle as she was still doing her job.
Tama was later stopped by Roka and Chitose join in to stop Tama after Roka give her courage to stand up for herself. Soon the three became great rivals to one another throughout their life as they would play games to see who would win, giving each step for Chitose to become the person she is today. In the past she and the previous student body president (Tama) had a battle and Roka Shibasaki had to end it. It is unknown what type of battle they had.
Back when Roka Shibasaki was still in the Real Game Creation Club, she was treated cold and indifferently by most of the club members due to her strange personality. This furious Chitose and decided to punish them by burying them up to their neck in sand, causing all of them to abandon the club minus Roka and Takao. Roka believed she was the reason the club was ruined and was feeling down while sitting on a bench outside until Chitose approached her and asked if she wanted to make her own game creation club which Roka agreed to.
