Toki Meka was originally Takeuchi Naoko's first manga after a hiatus of nearly four years. It appeared as a yomikiri in the September 2001 issue of Nakayoshi. At the end was a note requesting letters from people who would like to see a continuation, but shortly after, Takeuchi started the unrelated manga Love Witch.
The new serial Toki Meka! began in the January 2005 issue of Nakayoshi and ran until the April issue, in which Takeuchi promised a future return of the series as well as a tankoubon.
