Critical Reception of the series has mostly been negative with many reviewers comparing it to the 2004 series Elfen Lied, also created by Lynn Okamoto, and the many similarities between the two works. In reviews of the anime the story has been called "shoddy" and "incomplete" with none of the characters being particularly memorable or having much depth. In addition they have also noted the overuse of harem antics and cliches to the extent that the series often feels more like an ecchi harem comedy as opposed to a serious sci-fi/horror series.[
