Aya

Aya is a 10-year old girl that was adopted by Katsuko and Akira. Nothing is known about her past before that, though this will be likely to be revealed in Season 2 Arc 3. She is constantly drawing pictures and is a natural Michaelangelo at it. In fact, her drawings were so good that Pegasus hired her as a creator for Duel Monsters cards.

Appearance
She is always seen with a sketch pad and a pencil with a Pikachu pencil top. She wears what looks like a dress seen on a doll as well as long periwinkle hair wrapped in bright red ribbons. Her eyes are a grayish color.

Serene Dreams
It is revealed in Season 2 Arc 2 that Aya is not human at all, but really is the essence of dreams. This title is known as Serene Dreams and being that she can't draw blood was a problem to Jahrvis' plans. He used a machine to reverse her from dreams to nightmares which drew blood but killed her in the process. By dreaming real hard, Junichi and the others were able to bring her back to life.

Lifeless Corpses
It is revealed at the end of the Demise Realm Arc that Aya is one of the Grand Masters known as Lifeless Corpses. Not much else is known about this.

Relations with Others
Aya has many relations with the wide variety of the cast.

Junichi: The person Aya developed a relationship with. The two were really close.

Ryouta, Scott, and Pegasus: As all card creators, it was always up to these four to create and judge the characteristics of cards, though Aya usually let any kind of cards go for she just liked creating the cards for others.

Akira and Katsuko: These two looked after Aya as if they were her own parents.

Sakura, Shizuka, Rina, and Hana: Being all younger characters, Aya is able to relate on the feelings that can develop through these characters.

Bakura and Duke: Though this duo seemed strange to everyone, Aya actually saw them as great duelists who knew how to play the game right and was glad to create decks for the two when they were given the option of free decks.

Deck
Aya used a Spirit deck, which focuses on the card's abilities when played but also returned to the hand at the same time. Aya collected these cards for the wonderful art designs each put into the cards and never worried if she ever won or lost, as long as she got to use the cards she liked which is the true spirit a card maker should always have.

As Lifeless Corpses, she uses a Darkness Manipulation Deck, which focuses on using a Field Card called Yami no Sekai and uses her DARKNESS effect concept to play with her opponent's mind to make them go crazy and eventually commit suicide.
