A cold and ruthless girl with the power to bring the monsters and magic of Duel Monsters to life, an ability only used through anguish and sadness. Because of this, she chooses to distance herself from people, believing her power to be caused by the Dragon birthmark she possesses.
Aki is the daughter of Hideo Izayoi and Setsuko Izayoi. Her father was a congressman in Neo Domino City and as such, was often very busy and didn't spend much time with Aki. One day, it was Aki's birthday but her father had to go to party and didn't come home till she was asleep. While she was asleep, he gave her a deck which she had wanted. The next day, she woke and found it and was very happy but when she wanted to duel her dad, he told her he had an important job to do and would be gone for a month which only made her bitter and distanced them more. He eventually managed to find time to spend with her and they dueled but in the middle of the duel her father received an important call and had to leave immediately. However, Aki insisted on continuing and on accident she would discover her powers as a psychic duelist when one of her cards inflicts real damage to her father. At that point, she also became a signer and was given the sign of the Crimson Dragon's feet.Aki was confused by all this and her father, also terrified at what was happening, called her a monster and told her to stay away from him and though he didn't really mean it, what he said could not be taken back. Because her parents feared her power, they then forced her into duel academy, and when she was 13 years old, she hurt another student with her powers at which point everyone began to fear her. She went back home to see her parents and found them smiling and presumed they were happy that she wasn't with them anymore. Her parents took notice her, but she uses her psychic powers to cause damage to the house and runs away, telling herself that since her father was laughing, she should laugh at how he fears her.
Soon afterwards, she would take the mantle of the "Black Rose Witch", donning a mask and black robe, and she would strike terror in the people of Neo Domino City with her powers as a psychic duelist. She eventually met Divine - another psychic duelist - who would invite her into the Arcadia movement and would teach her that it was because she knew pain that she had power. He also promised that she wouldn't have to think about painful topics anymore and that he would think of everything for her.
One day, while a crowd of people is watching a duel in the streets, she rises out of the ground with her Black Rose Dragon, interrupting the duel and attacking everyone. When she appeared, Yusei's signer mark started burning and he confronted her. She then noticed Yusei's signer mark and was surprised to see he had one too and then said it was a detestable mark and disappeared. Aki is soon invited by Rex Godwin to join the Fortune cup and she accepts. In her first match, she faces off with Jill deLauncebeaux, a knight who swears to vanquish her. Jill comes close to winning, but ultimately Aki wins with her Black Rose Dragon and severely injures him in the process via her psychic duelist powers. In her next match, she faces off with Kodo Kinomiya, who had looked up her profile prior to the duel and exposes much about her past and although Aki defeats him and severely injures him as well, their duel would cause her signer mark to flare up. She then faces Yusei in the finals and during their duel Yusei sees that Aki takes pleasure in causing destruction and hurting others. Aki is first surprised to hear that she enjoys destruction but soon comes to accept it as well as everyone's fear of her. However, as their duel progresses, Yusei sees beyond her desire to destroy and sees that deep down she is filled with sadness because of how much she had been rejected by society. She tries to hide her face with her mask and her powers start going out of control but eventually Yusei manages to defeat her and break her mask in the process. After the duel, Divine took her back to their quarters for her to rest. Later, during Yusei and Jack's duel, the Crimson Dragon appears and takes all the signers present at the arena, including Aki, into a strange place where they witness the people of the stars as well as a vision of the Satellite being destroyed by a giant spider geoglyph. After the duel, everyone returns to the arena.
