Adrienne Guadiacco

Adrienne Guadiacco is a skilled female Duelist from the Obelisk Blue Dormitory at Neo Duel Academy, as well as one of Alexander Frost's closest friends.

In Japanese, her surname has been written as either ガインのイア共 or グダイア共同. Her given name can be interpreted as "Dark Haste", which may make a reference to Adrienne's temperamental and originally unpleasant attitude. She has also been called "Adrie" on certain occasions by her brother, Gregorio Guadiacco, and Alexander Frost.

Character Biography
Adrienne Guadiacco, along with Alexander Frost and Lionel Reyes, is one of the elite students at the Academy. She is widely regarded as the "Queen" of the Obelisk Blue Dorm for her prodigious Dueling talent and for her extraordinary beauty. While Adrienne is extremely popular at the Academy, she usually doesn't care for the company of others, except for Alexander, her constant companion and one true friend. She is also extremely seductive, and not above using her physical beauty to give her an edge against her opponents or to get what she wants.

Adrienne mourns for her long-lost older brother, Gregorio Guadiacco, who disappeared seven years ago. The mysterious disappearance of her brother, with whom she shared a very special bond, caused something inside her heart to die. Slowly but surely, Adrienne became a very pessimistic person, believing that nothing lasts forever and that all efforts to change one's fate are meaningless.

Adrienne places fifth in the Midterm Exam, and takes a spot as one of the Top Twelve Dueling Participants for the Homecoming Duel Tournament. After learning that a mysterious girl named Yuuki Vandrille obtained a perfect score on the exam, she and Alexander begin to investigate her. After a fruitless search of the Academy's computer network, she and Alexander go to the Ra Yellow Dorm in search of Hayden Omirou - another one of the Top Twelve, and famed for his habit of keeping tabs on other Duelists - to obtain information on the other competitors. Although Hayden proves initially difficult, Alexander is able to defeat him a Duel and gather the information successfully, along with several interesting insights about Yuuki's unhappy past. Due to their rough treatment of Hayden, they make enemies of both Raphael Luiseruga, who witnessed the confrontation, and of the disgruntled Hayden.

On their way back from the Ra Yellow Dorm, she and Alexander also encounter Aurion disguised as Mark Tanner. Angered by Mark's disrespectful attitude, their meeting does not go well, prompting Adrienne and Alex to manipulate Lionel Reyes into defeating Mark Tanner and gathering information on him in exchange for their support in the Homecoming Duel Tournament. After gaining the desired information from the successful Lionel, she and Alexander break their end of the deal and refuse to help Lionel, making yet another enemy.

Adrienne's first opponent in the Tournament is Sir Edgar Deboit, a wealthy and eccentric sculptor. After extending the Duel painfully, Adrienne claims victory. She and Alexander are later approached by a mysterious man who seems to know Adrienne. Determined to discover his identity, they begin to investigate, only to stumble upon the sinister Lucien Lachance instead. Lachance reveals his true persona - the leader of the Dark Brotherhood - and offers them a chance to join. He also seems to possess strange knowledge of Adrienne's late brother, Gregorio Guadiacco, who went missing many years ago. With Alexander's support, Adrienne is able to resist his tempting offer and denounce him as evil.

After a frightening public display by the Brotherhood, many of the Tournament's participants withdraw, expressing concerns with security and their own safety. Due to this, Adrienne wins her planned match against Hayden Omirou by default, and is sent directly to the Semi-Final Rounds. To her shock and dismay, she learns that her opponent for this round will be Alexander, her one true friend. Despite this, Adrienne expresses her determination to win, and promises Alexander that she will give their match her all.

Deck
Adrienne plays a Gorgoness Deck, given to her by her father and constructed with her brother's help. Her tactics are well-balanced due to the variety of different effects at her disposal, ranging from the destruction of her opponent's Monster, Spell, and Trap Cards to the Summoning of her three Ritual Monsters, the Gorgoness Sisters. By using her Snake Garden Field Spell, Adrienne is able to increase her snake army, or to facilitate the summoning of her three Gorgoness Sisters.
