Фуджівара Міцуру

Although he is a classmate of Ai Kunugi, Mitsuru Fujiwara rarely attends class. A very lonely boy, he is often found following and photographing Misaki Saiki. He also sends Misaki text messages on her cell phone, no matter how often Misaki changes the text address. Even though his behavior is that of the classic stalker, Mitsuru means no harm to Misaki. In fact, he would often help Misaki out of cases she is involved in... or when those close to her are in danger. (source: Absolute Anime)
