The blue flame samurai is a direct translation of the name Shien (...)
It's not a blue flame, and the description says that it serves a red flame, so something got twisted.
It also appeared in the anime, and the appearance itself is an ordinary samurai character.
Afterwards, it was re-released as a card called Xyz Monster, Shadow of the Six Warriors -Xien-!
I thought it would be great to show the old cards again like this!
