Yua Yamamoto/Synopsis

## History

Yua was born in Shibuya's red light district to a prostitute for a mother and an unknown father. Her mother abandoned her at birth, fleeing to another city.

Yua then grew up with a man known as Masaway as her guardian, who also took in an orphaned Draken. The young women that came and went in the brothel taught her how to cook, clean and how to properly take care of herself and her brother. She'd do everything on her own, growing up to be very independent.

When Draken brought his new friend, Mitsuya, over to the brothel, she served him tea and played poker with him and the girls. Yua, after hearing about his sisters being alone at home, walked there with him and made food for them. He wanted to pay her back in sime way, but Yua just told him to treat her to coffee when they met again.

After a few months, Draken got a dragon tattoo on his temple, causing her to get slightly mad at him. When they encountered Mitsuya again, she laughed seeing that they had similar tattoos. Yua called them the "Twin Dragons", with the duo adopting the name.

Mitsuya then asked if she could accompany him, and so she did, stopping at a coffee shop. He completed his promise to her, buying her coffee, and asking Yua to come by again because his sisters missed her. She agreed, going to his home regularly.

Eventually, Yua became close with the founding members of Toman and became their first member under Mitsuya's division.

Draken got really sick the week before Yua's finals week, and it caused her to skip school a few days so she could take care of him. One of her teachers was failing her on his subject on purpose, so she crammed while she took care of him. However, once Draken wasn't sick anymore, she started to feel unwell herself, but didn't tell anyone, deciding to go take her finals since they were important. She walked with Mitsuya to the school, but they were confronted by another gang. Naturally, they had to fight them, and once they were done, Yua collapsed.

She was diagnosed with pneumonia after Mitsuya called an ambulance and got to the hospital with her. Draken looked over her as she stayed in the hospital for a couple of days, and got a call from the school telling her that she failed to complete her exams so she had to retake the year. After being discharged, she went with her guardian to speak to the school board, only for her to be denied retaking her tests, claiming that one of the teachers marked her present, and thus resorted to repeating her third year of middle school.

A few months afterward, during break, she was walking back home with Mitsuya to have a movie night, but ended up coming home to Draken and Masaway threatening a man at the reception desk while some of the girls eavesdropped. Seeing she had arrived, Masaway asked her to hear out this "customer" and took Draken to their rooms in the back along with Mitsuya. The man asked if her last name was Yamamoto, to which she nodded. He explained that he was her biological father, the CEO of a fashion company, named Alfred Astor.

He told her how he stumbled upon her mother three years ago in another country by chance, and once she had mentioned the daughter she left behind, he became enraged and sought out to find her. Yua asked him how he knew he was her father, and he replied that her mother had only slept with him during the conception date. He left the establishment not before telling her that he wished to get to know her and be there for her, leaving his phone number and saying that he'll leave Japan in a week.

## Plot

### Toman Arc

Yua is first seen at Toman's meeting at Musashi Shrine with Mitsuya, seeing two Toman members trying to chase away a boy, realizing that he was Takemichi Hanagaki, she goes to scold the members for trying to dcare the commander's guest, calling Jihye Hasegawa to get him and his girlfriend over to Mikey.

Draken then calls her and Emma over, telling her to protect Hinata incase anything happened. After the meeting is over, she hands Hinata over to Takemichi and properly introduces herself. Upon close inspection of her, Takemichi realized that she was a popular model back in the future, and blushes, causing Hinata to get slightly mad, and Yua to get confused.

### Moebius Arc

In an eventful day, Yua received a call from Draken while she was studying at home, telling her to go to an address and help a passed out Takemichi, saying that he also called Emma, and Jihye was waiting there for them. A but pissed that they had gotten in a very terrible fight, she took Draken's bike and went there, staying until the ambulance arrived. While Jihye rode in the ambulance with him, she transported Emma to the same hospital, and later took Jihye home.

Arriving home to a pissed off Draken, he told her everything that happened, even the situation with Mikey, and later made him his favorite food to help him calm down. Yua was very upset that Pah-chin had been arrested, but had to keep it together for him.

Several weeks passed, and Yua was getting worried for Draken and Mikey's relationship, even going to the extent to calling Mikey over, which resulted in him venting to her. He left, only for the both of them to come home getting along several hours later. She happily made them their favorite food, taking a picture of them together.

After a few days, she met Mitsuya as they were walking to school, and he stopped her to give her a new choker. As well, he asked her out to the Fire Festival on August 3rd, and she shyly accepted, a blush spreading on her cheeks.

The day soon arrives, with the girls at the brothel helping her get ready and teasing her for her date. Yua waited for Mitsuya at the entrance of the festival for a long time, until it started to rain. Once beginning to leave, she got a call from Baji, and he came to pick her up to go and fight Moebius at Mikey's orders.

Upon arriving and seeing her brother bleeding from the head, she got off the motorcycle and began to fight along side Mitsuya as she was part of his division. Yua was distracted the whole time, until Emma called her that Draken had been stabbed, and she took off to the address she had told her, finding Kiyomasa's group beating up Takemichi and his friends. She jumped, kicking one of them, instantly knocking him out.

They ran away after hearing the cops, and the ambulance soon arrived. Yua and Takemichi rode in with him as he was being transported, with her crying once Draken went into cardiac arrest, but was able to be resurrected. She waited quietly with Mikey in the lobby, not daring to look at anyone. Once the doctor told them that he was going to be making a full recovery, Yua dropped to her knees and cried, with Mitsuya hugging and comforting her.

When Takemichi goes to the present, along with looking up Jihye, he goes looking for her, finding out that she isn't a model anymore. Naoto manages to track her down to a very nice club named "Binding-Love", where she was working as a mixologist. Yua told Naoto that she had decided to leave the gang scene after second year of high school, when Draken told her that it was better for her to pursue a greater future. They made a deal, with Yua promising to give him any information she could gather in exchange for Naoto to take down Kisaki.

### Valhalla Arc

Bearing her Toman uniform, Yua stood waiting for her brother and Toman's commander in front of a public bath along with the captains. She asked if the ceremony was going to take long, since she had homework to do at home, only for Nahoya to laugh, stating that she was the only delinquent who worried about homework.

She followed the others to the temple, and the meeting begun. Yua wasn't very happy when Kisaki sat with his back to Mikey and her brother, much less when she realized that he was the new third division captain. Mikey ended the ceremony soon after, but much to her distaste, Takemichi went up and punched Kisaki in the face. Yua was going in to restrain him, but Baji showed up and punched him in the face as well, claiming that he no longer belonged to Toman, but rather to Valhalla.

Once the meeting was over, and Takemichi was knocked out, Yua went to follow Baji, calling out to him. Miraculously, he was alone, and she got to talk to him, trying to guess what he was doing, and why now. He mentioned Taketora being out of juvie, and she got a small idea of what he was talking about. Instead of yelling at him, she kept her cool, reminding him that Jihye and the others loved him a lot and had his back, telling him that she was there for him anytime, and she left.

On a day she had left early from the Home Economics club, she was followed by members of Valhalla and confronted by them, claiming that they had seen her around Mikey and the captains. They jumped to the conclusion of her being a girlfriend, and decided to get physical with her, pushing her around. Yua wasn't going to let anyone push her around, but even she knew she couldn't take down seven guys at once, specially seeing that some of them were armed in one way or another.

They tried to force themselves on her, but Yua wouldn't let them get their way. One of them held a knife at her throat, telling her not to move, until Tetta Kisaki arrived with his bodyguards, beating them up with her. The Valhalla members fled the scene, vowing for revenge, and Yua thanked him. Seeing that she was hurt, bleeding from a gash on her arm and a few bruises on her legs, Kisaki decided to walk her home, taking her school bag from her.

Yua thanked him for walking with her, telling him that she saw how much he wanted to fit in Toman, and that he was doing a good job with his division. He smiled and thanked her, asking for her to move to his division, but she declined, telling him about her being the first Toman member and being appointed to Mitsuya's division.

When they arrived in front of the building she lived at in Shibuya, they bumped into Draken, whom started to rapidly question what they were doing together, and after explaining, he thanked Kisaki and helped his sister inside. Yua invited him inside for some tea, but he declined, saying that she should rest.

Knowing that she'd have to fight in Halloween against Valhalla,, Yua began preparing herself both mentally and physically, as well as helping Mikey get a referee for the match. She made protein strong food for her brother, at his request, and worked out with him in the afternoon.

October 31st rolled by really quickly, and Yua found herself wrapping her chest in her room before heading out to meet the others at the temple so they could ride over to the abandoned parking lot. Once there, she looked around, seeing the Haitani Brothers, Leanman from Ueno, and Hansen, the referee she had gotten, from the Ikebukuro Criminal Black Members.

Both teams arrived soon after, and the fighting began once Kazutora knocked Hansen unconscious. Yua stayed fighting with her division during the whole ordeal, trying her best to keep up with the enemies coming at her. The enemies from Valhalla she had encountered days prior came at her as well, and she managed to take them down, but her stamina was draining fast.

One of the guys took her by her hair (a very low move, according to her) and tossed her around while others kicked and punched her. Mitsuya saw and managed to get to her, knocking them out and helping her up. Once Kisaki made it to Mikey, she cheered for him along with the other captains, gasping when Baji hit him with a metal pipe.

Yua continued to fight, until Baji lost consciousness in front of Mikey and Jihye. Declaring the fight to be over, she gasped when their leader knocked out Hanma with one kick, and started to beat up Kazutora. Yua watched everything that was happening while being held up by Mitsuya, and cried with everyone once Baji officially passed away.

After this, Mitsuya took Yua to the hospital, where they bandaged her up, and told her that her ankle was sprained. They told her to stay in bed resting, and so Draken took her home, where she stayed for a few days. Once Mikey called for a meeting, she attended, but wasn't at all prepared for what was going to happen.

Hanma Shuji announced that Valhalla would fall under Toman, making them have 450 members. They called Kisaki up towards them, and Yua smiled at him, gaining a grin back. When Mikey mentioned Baji, Yua grew sad that she couldn't stop him, listening to what Chifuyu had to say. She was surprised when he mentioned Takemichi was the new 1st division captain, but was still happy for him.

However, she was really surprised when Mikey called her, naming her the new captain of the brand new 6th division. Yua wasn't ready for it at all, and needed Draken's help to get up the stairs to give her speech, apologizing for not being in her best shape. Everyone bowed their heads to both her and Takemichi, and later on, the meeting was dismissed. Yua went to speak to Mikey, whom explained that she and Hanma were going to co-captain the division, since it was very big with all the new members and he knew she'd be able to get along with him.

In the present, she is seen in the meeting with the rest of Toman's executives, wearing a black dress with very high heels, smoking indoors. Yua stayed silent while the ex black dragon members argued with the founding members, since they knew she did her share of the work, and very well, as Hakkai mentioned. When Hanma explained that their cover businesses were searched, he as well said that thanks to Yua's quick thinking, her place wasn't searched.

She explained that the cops entered her bar, and before they gave the order to search, Yua asked if they had a warrant, and when they didn't even have an order from a judge, she asked them to get out. Telling them that she'd go to their police station to denounce them for breaking her doors, asking for their names. Making it seam like she was just an ordinary bar owner, the police left, and Yua managed to protect her base and drug operation happening in the back.

The boys laughed, telling Hanma to give her an oscar for her amazing performance, until Kisaki arrived. He pulled her by the waist, close to him, with Takemichi realizing that the duo was together, leaving him in disbelief.
