Akiza Izinski

Akiza Izinski, known as Aki Izayoi in the Japanese version, is a main character in Yu-Gi-Oh! 5D's and was one of the Signers. She is also called the Black Rose, or Black Rose Witch in the Japanese version.

Akiza possesses an extremely strong special ability which sets her apart from the rest of humanity, and even the rest of the Signers. This psychic ability enables her to materialize and bring to life monsters and the effects of Duel Monsters cards, allowing her to freely control them similar to Yami Bakura and Jaden Yuki. Akiza is a young adult who is 18 years old of average height, with fair skin, brown eyes, and dark burgundy hair. Her hair is mostly chin-length with the addition of elbow-length bangs that frame both sides of her face. She rolls her front bangs with a device similar to a hair curler on top of her head, which helps her restrain her powers, while a bit hangs down on each side. For Turbo Duels, Akiza instead uses a form-fitting, red motorcycle suit which shows her cleavage, along with an enclosed helmet, and boots. Due to having been rejected by her parents as a child and treated like a monster for years on end, Akiza was initially a very insecure, unstable, and spiteful individual who viewed everyone around her as an enemy and took sadistic pleasure in deliberately hurting people with her powers. At the same time, however, she also suffered from immense self-hatred and was miserable in her personal belief that she would never be able to live a normal life no matter how hard she tried.

Although Sayer gave her hope in her life again when he took her in and showed her compassion, he also deliberately manipulated her for his own agenda, causing her sorrow and rage towards the world to only increase day by day. After meeting Yusei, however, Akiza finally started to question whether she had made the right choice to give up on herself and as a result, her focus started to slip and her performance started to decline. When Sayer was seemingly killed by Carly and her parents tried to make amends with her, Akiza (with help from Yusei) was finally able to find peace and obtain the normal life that she had desired from the beginning.

After reconciling with her family and finding her place amongst the Signers, Akiza became a much more selfless, sweet, cheery, and heroic person, causing her to develop a habit of jumping up to help her friends whenever possible. She also grew close with Leo and Luna, who came to see her as an older sister figure, and developed romantic feelings for Yusei, as displayed by how she would always get easily worked up whenever he was in some sort of danger[4]. Akiza's powers are that of a Psychic Duelist. These psionic ability enables her to materialize monsters and effects of Duel Monsters cards. Akiza originally despised her Mark of the Dragon, believing it to be the cause of her unwanted power and even noted it as a "wretched mark." She later changed her opinion after her second Duel with Yusei, who believed it to have brought the other Signers together as friends. While not fully explained in the Japanese version, in the English dub, Commander Koda states that Akiza's powers are derived from telekinesis, indicating that she can also mentally manipulate physical targets. During Luna and Leo's Duel against Lester, it was revealed that Akiza can also see spirits, like Luna.

Her capacities are exceptionally strong compared to other such users as Sayer noted that her powers exceed even those of the Dark Signers and has yet to realize her true potential. The full strength of her abilities and directly related to her psyche and emotional drive. This becomes more apparent after Dueling against Yusei in the Fortune Cup when she became conflicted by the respective views of Yusei and Sayar.

Initially Akiza had little control of her incredibly strong powers. She uses a special hairpin ("energy stabilizer" in the English dub), to help restrain them. When she completely loses control, the pin gets flung off and her powers increase. After her second Duel with Yusei, she began gaining proper control of them, stopping herself from harming her father. Since then, her control continued to improve, able to, much like Sayer, manifested her cards outside of a Duel and likewise control her manifestation's actions beyond aimless attacking, such as using her "Rose Tentacles" to rescue Yusei. She can also chose to not physically manifest her cards as during her first Turbo Duel, she didn't cause any real harm to Trudge.

After Team Catastrophe caused her to crash, her psychic abilities disappeared. At first, Akiza felt uneasy about this, but ultimately realized she did not need special abilities to help people. Ultimately, however, her powers returned after her Duel against Sherry, instinctively manifesting "Black Rose Dragon" to protect herself, Crow and Sherry from falling rubble. In that instance, it also displayed the ability to heal wounds. Akiza also states "Black Rose Dragon" protecting them to be her monster's will. she is a kind person thanks to Yusei!
