This anime follows Iku and her fellow soldiers as they protect various special books and artifacts from the oppression of the Media Enhancement Law Commission.
The Tubi TV folks have now brought out the full thirteen-episode run where it’s free to view on their site.
In the near future in Japan, the Media Enhancement Law has been forced upon the population censoring all books and media.
Just like distribution elsewhere, it’s available in its original Japanese language only as no dub was produced for it.
