This is the very first monster played in the first episode of the Yu-Gi-Oh! anime by Joey Wheeler, making it the first card ever played in any series of Yu-Gi-Oh, besides Season 0.
This card's TCG name suffers from a mistranslation: 'Blue Flame' is a translation of 'Shien', and 'Kagemusha' means 'Body Double', making this monster "Shien's Body Double", and therefore affiliated with the "Six Samurai".
This monster has a counterpart (or possibly a later form) in "Kagemusha of the Six Samurai". They both share the same color clothing and hair, as well as being a mirror image in posture.
