Card Appearances:Isolde, Belle of the Underworld

Manga

 * In Rank 39, Kyoji Yagumo uses this card during his duel against Shark. He Special Summons this card from his hand while he controls "Tristan, Knight of the Underworld". Kyoji then uses this card's other effect twice, doubling both its own and "Tristan's" Level, before overlaying this card with "Tristan" to Xyz Summon "Number 23: Lancelot, Dark Knight of the Underworld".
