- This monster appears in the artworks of "Level Retuner", "Mistake", "Mistaken Accusation", "Mistaken Arrest", "Shared Ride", "Tour Bus From the Underworld", "Tour Bus To Forbidden Realms", and "Tour Guide From the Underworld" (alternate artwork only)
- The last five aforementioned cards are part of the lore of "Sangan". While making a tour trip to his homeland, the Underworld, "Sangan" ended up on a wrong bus, being picked on by the monsters from "Tribe-Infecting Virus". After fleeing from the bus, "Sangan" shared a taxi ride with the angel from "Graceful Charity". Unbeknownst to him, the driver, an imp from "Delinquent Duo", was illegally transporting a "Pot of Greed", and when stopped at a checkpoint, he and the angel were arrested as accomplices. When last seen, he was in a holding cell with "Witch of the Black Forest" as "Sangan" sobs while clinging to the bars (apparently saying something to a guard).
- This card's name "Sangan" is the Japanese term for "Three Eyes" (三眼 sangan).
- This card has a conceptual counterpart: "Witch of the Black Forest"
- The summon-triggered effect of "Umbramirage the Elemental Lord" is based on this card.
