Mimori Seiteikouji was the student council president, and the granddaughter of the school chairman. She initially places Souta in the remote Quest Dorm but helps organize its renovation. She participates in the school board meetings, and takes actions from there to the dorm.
She has a really positive, but clumsy attitude to her.
Mimori has had a crush on Souta ever since he went on a date with her and was really kind to her, as it was her first date. Ever since that, she has developed a shy personality around him and tries to spend more time with him. She has a habit of staring at him and making it seem like he was staring at her, much to his confusion.
She was the one who placed Souta in the old dormitory, but helped them renovate the dorm. Actually the higher ups weren't okay with the establishment of the dorm but she suggested that the quest dormitory would be allowed to stay if they were able to win the upcoming sports festival.
She had an older brother and everyone believed that he would succeed the Seiteikouji family, but after his death Mimori succeeds the family. She thought that she needed to inherit what her brother left.
