Anna Shuri/History

Chapter 1
During the battle against a Sagako, the group loses Yuko when she sacrifices herself to preserve herself in an onion. As a replacement, they decide to kidnap Eikichi to take his sister's place, being Anna the one who knocks him out, so she can take him away.

She later in the hot springs, she is responsible for cleaning up the mess that Eikichi left in the onsen.

Chapter 2
She is responsible for making Eikichi do the physical training so that Eikichi starts gaining Misogi power. Later, Hanako plays a prank on Eikichi by making him do the housework. When Anna sees him heading towards the bathroom, she tells him that cleaning the house was a joke from the Busters and that as a part-time worker, that's her job. Anna also tells him that if he wants to increase his sealing power, he must start investigating what his sister was doing.

In the afternoon, Eikichi manages to seal the first Sagako effectively. Anna and Hanako arrive at the place, which is Cape Hado, where there was a curse that made couples fight. Anna exclaims that she would like to have a boyfriend.

Chapter 3
Anna alerts the group to the incident of a possible Sagako at the Maryina club. The group arrives at the disco, where Anna has VIP access and is known as the queen of Saga. But Sagako attacks first with her cursed music and makes the girls go crazy with it.

Unsuccessfully even before this mission, Tae realizes that the Sagako was looking for triple A. Instead of searching for a man to fulfill it, they decide to make their own. Therefore, Eikichi must now train to meet the “triple A”. Anna is responsible for making him look like someone with a high income in Saga, taking him to a club where she also works so that he can become a host and can train properly.

Despite all of Eikichi's training, the Sagako realizes that he is a fake and attacks again. Fortunately for them, Eikichi was already prepared and managed to successfully seal the Sagako.

Chapter 5
The group spends the morning at a restaurant, eating and drinking to celebrate MJ's return to the team. Anna accompanies the others to the party with some liquor.

The next day, she wakes up receiving a call from a Sagako that showed up at Minami's school.

Chapter 6
Although the call about a Sagako was partially wrong, she helps the Busters defeat the Sagako. To accomplish it, one of the girls should dress up as a schoolgirl, but Anna is not willing to do it to attract the Sagako, so it is Tae's responsibility.

Chapter 7
Anna and Eikichi are looking for a Sagako around the Karatsu train station. When Anna turns to look to the side, she sees Keiji and freaks out. She quickly distracts Eikichi, so he doesn't notice where she's gone. Anna follows Higashino until he disappears from her sight. Unexpectedly from her, he manages to intercept her from behind and is surprised to see her in a place like Saga.

The Busters are surprised that Anna has disappeared, and they tell how it was the first time she arrived: Anna was a mysterious girl who saw the job poster for Saga Sagako Busters, and without hesitation she accepts the part-time job despite the crazy that sounds like fighting supernatural beings in Saga. Later, she is shown to be very skilled with the tools that Hanako creates and, being very observant of details, she helps the group by defeating the Sagakos in a more efficient manner.

Higashino takes Anna to a dark alley, where they talk about past events. There it is revealed that Anna was an excellent thief and since Higashino couldn't catch her in Tokyo, he was demoted to Saga. Higashino doesn't believe Anna that she is saving Saga from supernatural beings and thinks that she lost her mind when she came to such a desolate place. That's what he believes until he sees a Sagako approaching the two of them. Anna is ready to fight, but before she can do anything, Keiji fires his gun at the Sagako. Confused, she doesn't notice Keiji threatening her with her gun, now interested in her history of supernatural beings in Saga.

Chapter 8
While Anna is missing, Eikichi goes looking for her throughout the city until Anna finally finds him. To his surprise, Anna wants nothing to do with Sagako Busters. Knowing that something is wrong, Eikichi confronts her about her reasons for leaving the group.

Anna agrees to tell him the truth of what is happening. Anna's parents and family were phantom thieves, and she was the only child in the family. There was nothing she couldn't get. A life without problems. What she considered normal was different for others, and she herself left that life to find what was “normal” for the rest of the world.

When she escaped, she realized the reality of the world; beneath those people who lived in prosperity were people struggling with poverty. Without any protection, Anna was just another kid on the street, so she took advantage of her family's skills to survive until she was apprehended by Keiji. At the interrogation, Keiji talks to Anna about her family and how he could send her straight to the police, but instead he decides to team up with Anna to catch and detect robberies in Tokyo. With Anna's eagle eyesight, she could spot places where thefts would occur and inform Higashino to make arrests in exchange for him keeping her identity a secret. But living a life like that has its consequences.

One day, Anna sniffed out a grand plan made by a group of thieves and when the day was ready, she told Higashino. But the operation was so big that he had to call in reinforcements. Obviously, the criminals didn't see it coming, and it was pure chaos. Many lives were lost that day. People died because of Anna.

With the guilt of her actions haunting her, she fled as far as she could. She ran and ran until she reached Saga, where no one would know about her and she was completely sure that no one would recognize her. In Saga, she found work and a place to stay and out of fear of losing everything again, she did part-time jobs as a front in case something happened. Eikichi tells her that with the group of Sagako Busters, they will face the problem together, and that she should not carry all the weight on her shoulders. After all, that what normal means. Eikichi receives a notification from Sagako, and asks Anna what she will do from now on.

While Tae and Hanako fight the Eel Sagako, Eikichi and Anna show up to help them. Anna doesn't hesitate and attacks the Sagako by throwing them into the air. That is the place where she belongs and the place where she was accepted as she is, so she is determined to defend it. With the Sagako downed, Eikichi can calmly seal them with an onion. Anna proceeds to apologize for missing, as without her, the group isn't the same as it was before. She tells them about the problem she currently has with Higashino, but not before saying that even though she prefers older, she finds Eikichi attractive.

Chapter 9
Anna informs the rest of the group about her relationship with Higashino and the danger he is to the group. She questions Jofuku about what would happen if someone destroys a Sagako without using onions and Jofuku gets up annoyed saying that doing that will only make the curse stronger. Hearing his response, the group decides to split up to stop Higashino from killing Sagakos.

Chapter 10
She is the first to notice that MJ has changed his appearance, as if he had aged 10 years all at once. MJ warns about more Sagakos in Saga while looking visibly weak. Arriving at the location, the group sees a massive amount of egg-shaped Sagako as a result of Higashino shooting several of them earlier. Anna proposes not to leave them in the woods where they can cause damage and with the rest of the team, they pick up as many as they can and take them by truck to the mansion.

A week later, the group unsuccessfully tries to get Eikichi out of his room. Anna is very upset with Higashino and promises that when she finds him, she will make him pay the consequences of his actions.

Chapter 11
Along with the other girls, she is in the mansion as a thunderstorm hits Karatsu. Unexpectedly, lightning strikes the house, causing the Sagako they had stored to merge and causing the house to collapse on top of the Busters. Fortunately, she and the others manage to take refuge and save Jofuku.

Now they can only watch as a huge spider-like Sagako heads towards the city and then kills Higashino as he approaches her, looking for her so that the Sagako fulfills his “wish”.

Chapter 12
After an intense fight between Tae and the giant Sagako, Anna takes care of Tae's injuries on her body and suggests that they go to the hospital, which Tae refuses.

With no place to stay and no money, they go to the Hyodo house and Anna takes it upon herself to carry the weak Jofuku on her back. The group is received in a good way, and they manage to stay well that night. Tae then tells them the truth about the spider Sagako and how she is responsible for the death of her parents.

Chapter 13
A month has passed since the giant Sagako appeared and destroyed the Busters' headquarters. The group now bid farewell to the Hyodo family, searching for the Sagako. The Busters are staying at a hotel and find themselves reading newspaper articles for more information about sightings. Hanako finds the article talking about Higashino's death, and Eikichi finds an article talking about a giant spider in Takeo's area. Now the group has a new place to go.

Upon arrival, Tae tells them that this will be their new temporary headquarters, and the group splits up to search for the giant spider. Anna heads on her own towards Arita, while the others split up on their own.

Upon learning of Hanako's disappearance, Anna goes looking for her out of fear that something has happened to her. She finally meets Magatsuhi on a road. Remembering that Hanako said that she was going to help a little child, she asks her to stop for a moment. But suddenly, she is attacked by Magatsuhi, and although she tries to defend herself with what she has, Magatsuhi wounds her in the shoulder and leaves her incapacitated. With nothing going for her, she regrets leaving alone after the little Sagakos stopped showing up.

Chapter 15
She comes to the aid of Tae and Eikichi, along with the previously sealed Sagakos. Anna thanks Eikichi for keeping the Sagakos warm, as it allowed them to hatch like eggs. With the group reunited, the Busters prepare for the final battle.

Chapter 16
The group manages to defeat the spider Sagako, or so they think. Magatsuhi returns with a new and more powerful form. Anna stops Eikichi from going to battle with Tae, since with his leg injury, he would only be a burden. But Anna and Hanako did not get to do anything, as it turns out that Hanako created and designed a Sagako anti-spider cannon in the time they were free. The cannon hits the Sagako and parts of her body fall towards Tae, but Anna manages to stop them.

Tae manages to seal the Sagako thanks to Eikichi and Yuko's onion. The Busters wonder where the Sagako spider went, and Eikichi tells them that the Sagako is now sealed.

Chapter 17
5 years later, Anna arrives in Saga by plane. She finds herself reading newspaper articles where Hanako is on the front page of, winning several awards around the world thanks to her researchs. The group plans to meet in Saga for their 5th anniversary of their “promised day”.

Anna arrives at the Hyodo house, where she is greeted by Yuko. At home, she tells them that although her police work in Tokyo is not dangerous, she does keep her quite busy. Yuko tells her that she can relax at her house, since it is her second family after all.

5 years ago, Tae seals the Sagako within herself and Yuko is released from her onion, now fused with Niji-no matsubara's Sagako. Anna and Hanako find themselves somewhat uneasy about Eikichi and Yuko's sibling love, thinking that Yuko was an independent high school girl. While they were talking about that day, Hanako makes a surprise entrance to the house and tells them that since that day, Sagako has not appeared again and peace in Saga has returned.

With the group reunited, they go to the cemetery where Tae's grave is located and find MJ and Eikichi there to celebrate their “promised day”. Anna Shuri/Historia
