Her standard attire is a uniform that consists of a slate-colored jacket with a light blue trim, which she wears over a light yellow jumper.

As Blue Angel, true to her name, she has long blue hair that she tied into two with blue ribbons. Her eyes and eyebrows are also blue and she has a green clover tattoo on her right cheek. She wears a blue choker and pink heart-shaped winged earrings. Her outfit consists of a white sleeveless shirt with a blue necktie. Underneath, she wears a blue and pink dress with wing-shaped frills, and dark blue thigh-high socks. She wears dark and light blue boots with wings attached to each one. Lastly, she has a pair of white wings with pink heart-shaped and lavender clover-shaped patterns on each wing.


Aoi is described as being very nice, polite and reserved on first sight. However, as a Charisma Duelist, Aoi becomes very active in LINK VRAINS. As Blue Angel, her personality is very bubbly and she is a smiling idol with a cheerful demeanor. She is very obedient to her brother-in-law, Akira, but also wants to prove herself and is willing to show him that she can handle something on her own. She seems very distrustful of others, as she thinks most people only approach her for her connections to SOL Technologies.


"Aoi" (葵) means "hollyhock", a plant associated with abundance and great fortune and was also the emblem of the Tokugawa family. "Aoi" may also be derived from (青い), a Japanese word for Blue, reflected by her alias, "Blue Angel." The characters that form "Zaizen" (財前) can be translated as "before wealth".


In LINK VRAINS as Blue Angel she can summon and create a blue energy whip.[2]



Aoi first appeared as Blue Angel and was about to face a Duelist in LINK VRAINS. Before she was able to begin the Duel, an unnamed Knight of Hanoi attacked. She ran away in fear, and was about to be attacked by "Cracking Dragon", although Playmaker saved her.[1]She then watched the Duel between Playmaker and the Knight, and when Playmaker fell from his D-Board, she returned her debt to him by throwing him back his D-Board with an energy whip she summoned.[2] After Playmaker defeated the Knight she and Go Onizuka approached him and challenged him to a Duel. He refused their challenge, claiming that he had no interest in either of them and left, much to their dismay.[3]

After she defeated an opponent in a Speed Duel, she logged out of LINK VRAINS and went to watch the sunset. Meanwhile, Yusaku discovered her Blue Angel persona and decided to track her down the following day at school, after his friend Shoichi Kusanagi suggested he do so to gain an audience with Akira. He watched her enter the Duel Club, and when he reluctantly joined in after her, she introduced herself. When he asked about the new Duel Disk model used by everyone in the club, Naoki Shima, another member, started bragging about how Akira had given them all the new Duel Disks, and Aoi shot him a stern glare.[4]

When Ignis tried to start a conversation with Aoi's Duel Disk, Aoi noticed that Yusaku's Duel Disk was a card-loading model, the same as Playmaker's. She then asked to see Yusaku's Deck, and Yusaku handed it to her, though it was actually a dummy Deck and not his real one. After she looked at the cards, she politely handed it back with a word of thanks, but Naoki snatched it up and started laughing at the cards. She looked on as the club's president scolded Naoki for insulting the Deck, and Naoki apologized and gave it back to Yusaku.[4]

After school, Aoi returned home to her apartment, and the housemaid robot there told her that Akira would not come home because of work. She turned on the TV and saw him deflect press questions about Playmaker's Duel against Go. When he was asked if Blue Angel would Duel Playmaker next, he said no, at which point she turned the TV off. That evening, she got a call from Akira, who asked her why she was unhappy, then told her to stop Speed Dueling immediately because it was dangerous and she could die, and because he cared about her. He also told her not to let anyone find out she was Blue Angel as it could jeopardize his position. She timidly replied that she understood and hung up, but then reflected on her resolve to show him that she could hold her own, and decided to Duel Playmaker.[4]

She entered LINK VRAINS and, after turning down several Duel requests, issued a public challenge to Playmaker to come out and Duel her, with Yusaku and Shoichi watching. Yusaku refused her challenge, as she was not a Knight of Hanoi. After waiting in vain for Playmaker to show up, she was instead approached by Specter, who claimed to be a fan of hers, but she realized he was lying. He told her he wanted her to defeat Playmaker, and gave her a card, which he told her would free her hidden desires. After he left, she wondered what she was doing there, apparently having no memory of the incident.[4]

She bumped into Yusaku again the next morning at school. Ignis tried to talk to her Duel Disk again, but this time it gave an angry response, and Ignis immediately realized something was wrong. As Aoi and Yusaku walked to class, she asked him why he had joined the Duel Club, not believing it was because he loved Dueling. When Yusaku asked her about her brother, Akira told him that people only ever talked to her because they either wanted the new Duel Disk, or a job at SOL Technology after graduating. She told him not to bother asking because her brother wouldn't trust her, and ran off.[4]

While in class, she received a text from Playmaker accepting her challenge, though it was actually sent by Ignis. She excused herself, claiming she needed to go to the infirmary, but instead went to the rooftop to enter LINK VRAINS. When the Duel started, she felt a wave of excitement when she heard her fans cheering her on.[4]


Akira Zaizen

Aoi and Akira are in-laws. He appears to not care about Aoi that much, whereas Aoi is shown to have a big brother complex and idolizes him. Akira is aware that she is Blue Angel and Aoi wants to admit to him that she Duels.[5]

Yusaku Fujiki (Playmaker)

Aoi and Yusaku are classmates, but only Yusaku is aware of her alter-ego. As "Blue Angel", Aoi is shown to develop an interest in Yusaku's alter-ego, "Playmaker", after he saved her from a "Cracking Dragon".[1] She is shown to be grateful to "Playmaker" for saving her, and saved him in return after he fell from his D-Board.[2] She also has a desire to defeat him in a Duel to prove herself.[4]


Aoi uses a "Trickstar" Deck[1] that incorporates Link Summoning.
