Trivia

 * Its meaning "White Deer" might be a reference to the spiritualism of the white-colored deer, who are a sign of good fortune, in addition to one of divine blessing in multiple religions, such as Japan, in addition to Taosim, European and Indian.
 * Nanashi's comment about his sword being "too blunt" for Lancelot could mean that either it could not match up to the young man's might or it is more blunt if not used with Iai. It might be the former considering that Lancelot used Shirojika to kill Mortlach.
