- The Homunculus Token summoned by this card resembles "White Night Queen" in its' artwork.
- This card's name comes from "Blue Moon," an extra full moon in a given division of a year (i.e. 2 full moons in a month or 4 full moons in a season). The concept of a full moon is synonymous with a rare event ("once in a full moon") and, in popular fiction, can be associated with magical powers.
