Most of the frequent posters where college related, other gymnasts and jocks at her school as well as some classmates she had made small contact with. For the most part she seemed to try to keep to herself and didn't have many friends. She rarely posted and when she did it was about a meet that was coming up or to answer a person's question or to comment on a comment. One however did stick out a bit as looked closer into her posts. a Picture of her with another Japanese man about her age that was posted a few days ago. Kiku told the poster to take it down and the poster told her in a reply on the night Kiku vanished "But you two looked so cute, please???" Their was no answer after that.
You get a strong feeling from Ichirou that they killed the security guard during their interrogation.
