Kurimu Sakurano

For eight years after moving to her new home, Kurimu had no friends. At first, it was because there was a conflict between the adults that told their kids to avoid talking to Kurimu. However, even after the conflict is resolved, she is unable to make any friends. When she was 14 in her middle school years, she was asked to deliver things to the then hospitalized Anzu Tsuyuri. Despite an awkward first meeting where Kurimu had a hard time speaking, they soon became friends and Kurimu begins to open up to Anzu. They became really close that Anzu begins to call her Ku-chan. But, Anzu's condition grew worse and had to go through an operation where there is a high chance that she will not survive. Before the operation, Anzu wrote a letter to Kurimu and made her promise to make many friends. Anime: Student Council's Discretion
