KO Seiki Beast Sanjūshi: Gaia no Fukkatsu

Title

The title is a pun at the famous book The Three Musketeers by Alexandre Dumas. "Three Musketeers" is 三銃士 in Japanese (romanized sanjuushi). The Sanjuushi of the game's (and the anime's) title, however, is spelled 三獣士, the middle character meaning "beast". That's why the English translation "The Three Beasketeers" is most appropriate!
