Shintaro Kisaragi/Relationships

Ayano
Shintaro first met Ayano in school and she eventually made contact with him despite his tendency to keep distances. They became close friends. He caught her crying alone in a class room one day, but didn't know what to do so he walked away. When news spread that she committed suicide during the first high school year, he fell into depressions, thinking that she would be alive if he had talked to her the day before. Then, Shintaro decided to escape and isolate himself from reality to the digital world.

Ene
Shintaro was very surprised when he received Ene in a mail from an unknown sender and couldn't delete her anymore, because she had got her own will. He used to really dislike her for her mischief and jokes but has come to rely and trust her as shown in his faith in her during the terrorist incident.

Momo
Shintaro is Momo's elder brother and although he may not seem like it, he does care for her well-being and health dearly. She shares a lot of character traits with her brother.
