It was sold at Comic Market 73 held in the winter of 2007. It is a sci-fi work set on the Moon and in Gensokyo. Despite being a doujin work, it gained attention for casting famous voice actors such as Yui Sakakibara and Kana Ueda. Additionally, singers Nana Takahashi and Shihori, who were also active within SOUND HOLIC, took on voice acting challenges in this work. Yoshinori Sonobe, who played the role of Luna Marius, also voiced all other male characters in the work. Although he may seem overshadowed by the aforementioned famous voice actors, he is a veteran voice actor with a career spanning various Pokémon series, Fullmetal Alchemist, and numerous foreign film dubs. His casting in a doujin anime is unusual. In the opening scene of "Hoshi no Kioku," there is a military conference scene among the Luna executives. Yoshinori Sonobe skillfully performs four distinct roles, showcasing the prowess of a professional voice actor. Additionally, the voice actor Hitomi Harada, who had just debuted at the time, also appeared in the work.
