* DuelingDubs: Creator/MediaBlasters dubbed the first season, with plans for a dub of season two being abandoned, while Creator/{{Animax}} dubbed both seasons.
* FanNickname: Tako-Musume, for Tanabe Kozue (see ThereIsAnother).
* NamesTheSame: Cindy's last name is [[ScaryMovie Campbell.]]
* SeriesHiatus: Season 2 barely started before the show had to be placed off the air for two weeks, citing "a situation with the studio", to the disappointment of many.
** Worth noting: Two of the TV networks broadcasting the second season started two weeks late and did not go on hiatus at all; the overall effect was that the subsequent episodes premiered on the same day on every station.
* TalkingToHimself: Ika and the Ika cyborg that she battles are voiced by the same seiyu.
