- Author Existence Failure: Anastasia Moreno passed away from cancer on July 12th 2015. Thankfully Moreno was able to tell the rest of the plot to artist Nogami Takeshi who continued the story.
- Troubled Production: The English translation hadn't got an update since early October 2014 due to the author undergoing cancer treatment. Translations resumed in 2015 until the author's death in July 12th 2015. The English translation was to be taken over by Dan Kanemitsu but never materialized for years until Hyakuro Translations decided to take matters into their own hands and scanlated the rest of chapters in April 2018.
- Write What You Know: Co-author Anastasia Moreno was a Marine.
