Araki/History

Chapter 9
He first appears at the beginning of the chapter as a rookie police officer assigned to watch over Higashino and his actions, since Higashino from the first day he was in Saga had a lot of freedom of movement, the head of the police station assigned Aiba to watch over him. As they walk, they both talk about how Aiba became a policeman to which the young officer replies that his parents were too at some point, Higashino asks Aiba if he has heard about the "Sagakos" to which he replies that he only knows that there is a group of occultists in Saga who deal with supernatural matters. Shortly after, Higashino goes to take care of some business with Sagako to which Araki replies that he can't go alone since he has to accompany him at all times. He agrees and tells him to take him to a popular tourist spot in Saga or one that will be prosperous in the future, upon arrival they find that the forest is full of Sagakos that are constantly multiplying. Scared, Aiba is bewildered by what he sees but not before being shot down by a Sagako that Higashino threw at him to catch, they both see how this Sagako cries acid tears that destroy the grass around him. After Keiji's beating of Eikcihi, Aiba tries to defuse the situation by going after Higashino.

Chapter 10
At Saga Beach, Araki asks Higashino what he plans to do with a Sagako they had recently captured, since he had noticed that Higashino had shown some curiosity about such creatures for several days. Higashino tasks Araki with taking care of the recently captured Sagako in his apartment even though his residential complex does not allow pets, a task that turned out to be more complicated than Araki thought due to Sagako's powers of constantly spitting mud from its mouth, filling the apartment of a slippery mud. The Sagako he call Doro-chan hasn't eaten or drunk water for several days, which uncovers the curiosity of both officers who wonder if it is an ordinary living being. Back at the beach at the beginning of the chapter, Keiji decides to do a little experiment with the Sagako, but not before giving it a context of the beach where they are, being the prefectural border with Fukuoka, and he throws the Sagako across the border causing it to explode upon exiting and leaving a dark stain on the ground. Araki, shocked, leaves the place with visible disgust on his face.

Chapter 11
Araki helps with the evacuation of some residents because there was a strong electric storm, but knowing of the existence of Sagako he prepared himself with a shotgun to defend the people. He warns the residents of the appearance of an unknown life form and asks for calm in the meantime, but is surprised to see Higashino approach the creature casually only to be killed shortly after, leaving him completely shocked.

Chapter 14
After more than a month of the spider incident, Eikichi and Tae go to his aid so that he can give them information about the recent disappearances in Saga, Araki, however mentions that they are inundated with unsolved cases and that the police still don't know anything. However, he mentions that the places and times of the crimes are impossible for a human to carry out, but it is assumed that it may be some organized group. When the Sagako are mentioned, he simply decides to change the subject and tells them that he already forgot about "that incident", referring to the giant spider and Higashino's death.
