Magatsuhi/History

Chapter 10
When Higashino throws a Sagako across the border of Saga, and it explodes, suddenly a mysterious figure of a girl with a demon mask appears who reveals some questions that he had previously and introduces herself as Magatsuhi. Understandably bewildered, Higashino can't believe how many strange things he's been living with ever since he came to Saga. Magatsuhi thanks him for eliminating that Sagako and makes a deal that if he eliminates all of Saga's Sagako, he will receive a “reward” and her original power will return.

Chapter 11
Two weeks have passed since the deal was made. Magatsuhi has manifested thanks to the negative energy released from the Sagako and has regained her power and communicates with Higashino.

He himself arrives at a meeting point in front of the traffic and begins to talk to Magatsuhi. She talks to him and seems to say something that makes Higashino angry because she seems to be unwilling to grant his wish. The discussion reaches a point where Magatsuhi decides to get rid of Higashino when he claims to fulfill his wish, going through his body with one of her limbs.

In Higashino's last moments, she tells him that if he had power, he could do whatever he wanted. Clarifying it that he was only used.

Present
Magatsuhi manages to manifest herself when she fuses the Sagakos that the Busters had in their mansion through lightning, resulting in the gigantic arachnid Sagako appearing again in Saga. Tae tries to destroy the Sagako, resulting in her being severely injured after the battle.

Birth of 1969
This Sagako was born from a child, literally. In the 1960s, Tae's parents found a strange creature that resembled a baby. They concentrated on researching her and raising her to understand her properties. All this in the laboratories of the university where they worked. When the government found out about this creature, they went to take it away as it was an unauthorized investigation and endangered public health.

When they were about to take the child away from Tae's parents, the Sagako was finally born, killing everyone around her.

Chapter 13
Around midnight, she appears at an amusement park in what appears to be a woman kidnapped. She uses her limbs to pin her against a wall as she constantly asks if she is about to cry or if she is hurting her. Only to end up crying as she says some unintelligible words.

Magatsuhi reappears in front of the Sagako Busters team, this time being her victim Hanako, who mistakes her for a lost girl and offers to help her find what she says she lost, which Hanako interprets as her family.



At night, Anna meets Magatsuhi again and remembers that Hanako said that she was going to help a lost child. To her surprise, she is attacked by Magatsuhi and is severely injured in her shoulder, leaving her incapacitated.

Chapter 14
Eikichi and Tae set a trap for Magatsuhi. Eikichi disguises himself as a woman to attract the Sagako who kidnapped women and thus guide them to where they were missing. Finally, she appears as a girl, which surprises Tae, who didn't expect her to be the Sagako. Although they try to escape, they are captured and taken away by Magatsuhi.

Chapter 15
Tae and Eikichi find the place where Magatsuhi was, the Takeo Ureshino Marchen Mura Village Amusement Park, and decide to go stop her. She surprises them by attacking from behind them, but is injured by Tae when she fights back. Magatsuhi catches up with the two and wounds Eikichi in his leg, but he is faithful to his attempt to communicate with the Sagako. She answers intelligible words, and in one last ditch for Eikichi, he shows her an onion, leaving her scared and confused.

They both try to run for their lives as she chases after them. To Tae and Eikichi's good luck, Anna, Hanako, and the previously sealed Sagakos come to their aid, fighting Magatsuhi.



Chapter 16
The group joins in one last battle, defeating Magatsuhi's spider form. She, on the other hand, transforms back into a sinister heart-shaped curse, with her at the center. Tae fights against her to try to stop her, but it is insufficient. Hanako, around the time she was released, created a Sagako anti-spider cannon and uses it, effectively destroying part of Sagako.

Magatsuhi still stands and in a thorn attack destroys the remaining Sagakos, leaving the team alone. Tae, who received the Misogi power from Eikichi and Yuko, makes an ultimate sacrifice and with Eikichi's help, climbs to the top of the Sagako. There, she touches Magatsuhi and in a burst of information she understands her motives and that he was looking for her mother, Mrs. Yamada.

Forgiving herself and Magatsuhi, Tae hugs Tae and the Misogi power of the onions instantly purifies Magatsuhi, breaking her mask and revealing her face. Tae used her body as a container for the curse and died in the process.
