- Many people have spread rumors across the internet that Ikue died. Thankfully, Ikue is alive and well.
- She was pregnant in 2006 which is why she had not finished voicing Gash Bell for the remainder of the series run. It was also mentioned that there were enough voice clips for Pikachu so nobody had to take over.
- She works under Mausu Promotion.
- She has a pet named Iku-chan.
