Daigo Sorano (空野大悟, Sorano Daigo) is the highest-ranking second-year Obelisk Blue student. He Duels Jaden Yuki in the Graduation Duel, and loses. After the Duel, he is defeated by Trueman; who uses his Deck and appearance in Duels against Tyranno Hassleberry, Syrus Truesdale, among other Duel Academy students and lock them in Nightshroud's World of Darkness.
It is revealed before Trueman Dueled Hassleberry while taking Sorano's form that Sorano was one of Hassleberry's first friends at the Academy.
Sorano is most likely revived after Jaden reaches out to everyone trapped in the World of Darkness and helps them to escape by believing in their cards.
Sorano uses a
Deck. His main strategy is bringing out " Horus Decree Lock Horus the Black Flame Dragon LV8" to the field as soon as possible so that way he can lockdown his opponent's Spell Cards. He would then combine this with " Royal Decree" to prevent his opponent from activating Trap Cards, thereby leaving his opponents with almost no way out of the lockdown. If "Horus the Black Flame Dragon LV8" would be destroyed, Sorano would use other cards to bring it back, so that way he can reenact his lockdown strategy. His strategies also involve using " Stop Defense" to forcibly switch his opponent's monsters into Attack Position so that way he can inflict as much Battle Damage to his opponent as possible.
