• In episode 1, Yuma Tsukumo sets this card during his Duel against Shark. In the next episode, Yuma forgets to activate this card in response to "Number 17: Leviathan Dragon" attacking "Gogogo Golem", though he later blames Astral for making him forget after Astral learns what Yuma's set card was. Later "Jawsman" attacks "Number 39: Utopia", but Yuma activates this card to prevent "Utopia" from being destroyed in battle this turn and make Shark take twice the Battle Damage he takes. However activating this card allows Shark to activate "Booming Urchin" which will inflict 1000 damage to Yuma during Shark's next turn.
    • In the first above-mentioned episode, this card can be seen after Yuma collides with a Litterbot.
    • In the second above-mentioned episode, this card appears in Astral's thoughts when he explains in detail to Yuma about the "Numbers" and how they work.
  • In episode 7, this card is shown after Yuma's Deck case falls out of his school bag and his cards fall out.
  • In episode 17, Yuma sets this card during his Duel against Fortuno, but did not activate it.

In the next episode, this card remained face-down on the field until the Duel was over.
