Card Trivia:Fallen Angel of Resentment, Satan


 * This is the awakened form of Yamato Tennoji after he wore the "Masks of the Divine Progenitor" as told in the story of "Corrupted Oath" starter deck.
 * This is also reflected in this card's Advent Condition, since Yamato took Ereshkigal (Dingir) and Crepus (Diabolus) as offering in said story.


 * This card is notable for having some distinctions.
 * This card is the first Z/X Extra card with only a single Tribe, and also the first Z/X Extra that is not a Dingir or a Waker.
 * This card currently has the highest printed Cost of all Z/X Extra, and the third highest printed Cost of any card in Z/X -Zillions of enemy X- TCG after "Inducement of Skating, Layback" and "Future Big Actress, Di Gi Charat".
 * This card currently has the highest printed Power of all Z/X and Z/X Extra.


 * While this card is not a Dingir, it still possess Advent Condition and the same card frame design (complete with the Dingir symbol and characters) as them. However, the Dingir characters on the left side of the card itself is written as "YAMATO" instead of its own card name like the other Dingir.


 * This card's Cost and Power might be a reference to the fact that number 13 is considered as unlucky number in some culture.


 * This card can be considered as the antithesis of "Seraph of Judgment, Uriel". Not only their naming scheme and pose in the PR version's artwork mirror each other, but their effect is the opposite of each other as well. "Seraph of Judgment, Uriel" gives Ignition Icon to your own Z/X and makes them appear in Square, while this card makes your opponent's Z/X loses Ignition Icon and eliminates their Z/X in Square.
