Getsumento Heiki Mina (月面兎兵器ミーナ, Getsumento Heiki Mina? lit. Lunar Rabbit Weapon Mina) was a fictitious anime which appeared in the television miniseries Densha Otoko. In the same manner as Kujibiki Unbalance, an anime that began as a fictitious anime/manga within the anime/manga Genshiken, it has been adapted into a television series, which itself was later adapted into a manga series. The 11-episode series has been adapted by the animation studio Gonzo. It premiered on January 13, 2007 on Japan's Fuji TV.
Anime News Network has reported that the official pronunciation of the series' title is Getsumen To Heiki Mina, not Getsumen Usagi Heiki Mina. In the Densha Otoko drama, it was named just Getsumen Heiki Mina. The Densha Otoko version of Getsumen Heiki Mina ran for 26 episodes, and the story is totally different from the real-world anime.
Regarding the cast, it was initially rumored that the voice actor for the main character, Mina Tsukishiro, would be Saori Koide, who played seiyū Karin, the voice of Mina in the Densha Otoko miniseries. It has since been confirmed that professional seiyū Marina Inoue is playing the role.
