Shay Obsidian

Shay Obsidian's History

Shay's homeland, Heartland City in the Xyz Dimension, was once a place where Duelists were loved and everyone enjoyed Dueling. Shay attended the Spade Branch of Heartland Duel School[3] known for training professional Duelists.[11] Shay was a rival to Kite Tenjo, the ace of the Clover Branch.[12][3] Whenever the two Dueled, they drew large crowds of children who looked up to them.[13] Shay and Yuto watched Lulu's Duel as the latter commented on her great Dueling skills. Shay told Yuto that she was his sister (adoptive actually) and after her Duel, he introduced them both to each other.[14] At one point Shay, Yuto, and Lulu watched a Duel of Kite's from the audience at an arena.[3] Shay witnessed Lulu lose to Saya Sasayama, and was furious both that she lost and that she accepted a card from Saya due to his opinion on such matters and he slapped the card from her hands.[10]

Shay during the invasion.

Heartland was attacked without warning one day by Duel Academy from the Fusion Dimension, and without an organized defense, lost comrade after comrade to their foes until they learned to fight back.[15] On one occasion, Shay fled from several materialized "Chaos Ancient Gear Giants" during the early days of the attacks on Heartland.[16] He, Yuto and three other Duelists attempted to fight off the "Chaos Giants", but the other Duelists eventually lost and were sealed into cards, forcing Shay and Yuto to retreat.[11]

After capturing a Duel Academy Duelist, Shay and Yuto questioned him about the reason behind the assault. After the interrogation, Shay tried to seal the Duelist into a card, but Yuto prevented him from doing so.[17]

Shay and four other Duelists arrived to witness Yuto Dueling Yugo. Upon arriving, Yugo fled on his Duel Runner and Shay asked Yuto where Lulu was. Yuto shook his head in response, prompting him to curse.[18]

At some point after that, Shay cornered another Duel Academy Duelist, who informed him that Declan was the Professor's son. Shay theorized that taking Declan hostage would force the Professor, Leo Akaba, to return Lulu and then proceeded to seal the Duelist into a card, despite the Duelist begging for mercy.[17] He traveled to the Standard Dimension to oppose the Fusion Dimension, and Yuto soon pursued him.[19][20]
