It really was because of this.
After hearing the reasoning from the shore, both the sisters of the Yamai family felt a bit helpless inside.
Honestly, although Makima often schemes behind the scenes, she hadn't done anything that had truly harmed their interests up until now.
They honestly didn't want to deal with Makima.
Moreover, whether it was the main mission or side missions, there were no hard requirements for the Yamai sisters to be in opposition to Makima.
What they needed to do was only mindlessly attack in this world.
Given the personality of the Yamai sisters, they weren't suited to get involved in schemes and tricks.
So their original plan was to finish the main mission as soon as possible and leave this world early, letting things follow the original story.
Besides, even if they were to kill Makima, they had no good plan for it.
Makima had already signed a contract with the president of Japan, and any harm done to her would be transferred in some other form to the Japanese citizens, making her practically immortal.
If they were playing the role of Six Omiya in this world, they could use the "Lock" ability to forcibly sever Makima's contract with the Japanese president, then directly kill her.
Or if they were playing the role of Shitono, they could freeze Makima, though they wouldn't be able to destroy her, they could ensure she was permanently sealed.
If they were playing the role of Honjo Nia, it would be even easier; with a single stroke, they could alter the contract between Makima and the Japanese prime minister.
But unfortunately, in this world, they had to play the role of the Yamai sisters, and aside from fighting, they were no good at anything else.
Though they felt a bit sorry for Denji, turning Makima into stir-fried ginger pork like in the original story was something he had to experience as part of his web of events, and even they couldn't interfere forcefully.
Thus, up until now, they hadn't made any plans or actions to target Makima.
But unexpectedly, the shore had come to them.
It turned out the Yamai sisters were planning to finish the main mission as soon as possible and leave this world, letting the world unfold as per the original plot.
But now, since the shore was preparing to involve them as well, they had no choice but to get involved.
After all, the Yamai sisters were not heartless individuals.
"Go ahead and continue speaking."
With that thought in mind, the sisters slightly reined in their hostility toward the shore and showed an attitude that allowed for conversation.
Seeing this, the shore didn't go on with a long monologue but instead briefly explained Makima's plan to the Yamai sisters.
The Yamai sisters quietly listened, occasionally nodding or asking questions.
However, this was all just an act.
Because they already knew what Makima's true goal was.
"Anyway, that's the situation. Makima will stop at nothing to push Denji to the limit."
After finishing what he knew, the shore's cigarette was nearly burned out.
Worried that the Yamai sisters might still remain indifferent, after explaining Makima's plan and true goal, the shore added, "Although Makima won't make a move on you for now, your strength far surpasses hers. You're a true, uncontrollable variable. Eventually, Makima will come after you."
This wasn't just an exaggerated warning.
In fact, Makima would indeed take such an action.
Because in her plan, she would use various means to make Denji lose his desire for a better life, causing him to voluntarily sever his contract with the Chainsaw Devil. Her method was quite simple: give Denji's companions and hope everything, only to cruelly take it all away.
Afterward, Denji would truly submit to Makima.
In this way, she could complete her control over Denji, thus further controlling the Chainsaw Devil.
And once she succeeded in controlling the Chainsaw Devil, the only one who could truly eradicate Devils and eliminate the concepts they relied on, Makima could finally make her ambitions come true.
She would control the entire world, using the Chainsaw Devil's powers to eliminate harmful Devils and create a truly equal society for all.
Throughout this process, all countries and Devils would become her enemies.
Including the Yamai sisters.
"Your words certainly hold some weight."
"Consider this, if Makima really plans to do this, both Yuzuru and Kaguya must be prepared as well."
After discussing this in a rather perfunctory manner, the Yamai sisters expressed their willingness to cooperate with the shore.
This made the shore greatly relieved.
When he first came to the Yamai sisters, he wasn't certain.
But within the Japanese government, Makima's growing power had almost completely taken over the Cabinet Office, transforming the Japanese government into a puppet government under her control.
Even within the Devil Control Bureau, the shore didn't know how many people had already been controlled by Makima and were too afraid to reveal any information.
A while ago, he had finally gotten the opportunity to meet with Koki, hoping to reach a cooperative agreement to deal with Makima. But after Koki and her concubines returned from Hell, they disappeared without a trace.
Even if they didn't die, it was certain they were hidden after being controlled by Makima.
Alone, surrounded on all sides, the shore had no choice but to rely on civilian Devil hunters for help.
Since the Yamai sisters were personally recruited by Makima, the shore had excluded them from his cooperation list.
But it was after being forced into a corner that he had no choice but to take a chance.
And the results were pleasantly surprising.
It was like finding a glimmer of hope in an impossible situation. Even the seasoned Devil hunter couldn't help but feel relieved.
"Once you return, it's best to act as though nothing happened. Don't raise Makima's suspicion."
After briefly calming himself, the shore's normally indifferent tone carried a hint of seriousness. "I'll take care of the rest. You just need to wait quietly for instructions. With your help, we will surely stop Makima."
"Understood."
"Received."
The Yamai sisters nodded.
After reaching an agreement, they no longer stayed any longer, pretending as though nothing had happened and dragging the corpse of the Sea Serpent Devil back.
Watching the Yamai sisters leave quickly, the shore let out a small sigh, as though a heavy burden had been lifted from his heart.
"It actually worked."
The ever-silent Hirofumi Yoshida spoke at this point, his tone somewhat strange. "I thought that even if they didn't take action against us, they'd still be a bit suspicious of your words. But I didn't expect them to agree to cooperate so easily."
"After all, they're Devils. They know what the Chainsaw Devil represents." The shore glanced at him. "If you thought I wasn't going to succeed, why did you come with me?"
"You put up half of your life savings. How could a civilian Devil hunter like me refuse?" Hirofumi Yoshida chuckled twice. "And if we can stop Makima, I don't mind lending a hand."
"Makima will be stopped."
The shore took one last drag from his cigarette before throwing the butt into the sea.
"Now, we just need to wait for the right moment."
