Trivia

 * This episode will likely explain why Towa never went though a demon power cycle in the Modern World, or at least how Sota managed to cover it up for a whole decade.
 * The episode shares similarities with "The Mystery of the New Moon and the Black-Haired Inuyasha";
 * Both episodes feature a half dog-demon temporarily losing all of their abilities during the night of a new moon.
 * Their hair color also changes from silver to black.
 * Lack of knife-sharp dog fangs, claws and superhuman senses
 * Inability to utilize their signature demon swords.
 * As Setsuna does not lose any of her abilities, its possible she will on the opposite end of the lunar cycle, the full moon.
