This monster's TCG name is the Japanese word for "Blade of the Crescent Moon" (三日月の刃 Mikazuki no Yaiba).
This monster's name is based on the trend established near the beginning of the card release of Yu-Gi-Oh!, where cards that had English (katakana) names in the OCG ("Crescent Dragon") were given Japanese translated names in the TCG ("Mikazukinoyaiba").
