Hibiki Watanuki is a member of the school council Intelligence Club and is constantly assuming undercover activities. She always carries a camcorder to record school events with her two subordinates Akira and Yuzuko in the anime episodes, especially those concerning Becky. When doing this, she will often change her mind about what to report on, always wanting to find a better "scoop". She considers Rei to be her rival. Her investigations often end with her (implied) death, though she is always alive and well in the next episode.
