Leiji seems to have an unsettling hatred for her, due to an incident that happened between them in the past. His only desire now is to crush Kanade in the concours, so as to get avenge himself for what she did to him in the past. When they were trapped in a basement in Episode 11, Kanade remembers the face of the boy that had given her the golden string and had helped her tune her violin when they were young, which turned out to be Leiji. She also discovers that he was the one who wrote her the letter which read - お前はここで終わるのか "Are you done for, here?" (or "Have you reached your limit?")
