Still, even though Isao had planned to take down Muzan by using Tamayo as bait, it didn't mean that he could do it immediately. Instead, he had to do it smartly, as he could only use Tamayo one time.
If he messed up, then it was as good as it was over.
Well, by then, he could only use his ability to control Biwa Demon to open the portal to the Infinity City by using his second ability, which allowed him to control all the beings whose DNA had been recorded within his body.
Still, if he could do that, then why did he do this?
There were many answers, but it definitely had nothing to do with Tamayo, okay?
"You didn't tell your woman?"
As Isao wished to lure Muzan to Tamayo's house, naturally, he stayed at Tamayo's house even if Yushiro didn't want to.
Or rather, under the words of Tamayo, there was nothing that Yushiro could do, and he could only agree to let Isao be inside the love nest between him and Tamayo.
Yet, when Yushiro was told to go to Isao's hospital to pick up some blood for their consumption, Tamayo used this opportunity to enter Isao's room.
Isao looked at Tamayo for a while and asked, "Why should I?"
"....."
Tamayo looked at Isao with a complicated gaze and asked, "You don't care about them?"
"I mean, I am going to return and stay alive. What's the point of telling them as if I am going to die?" Isao asked speechlessly, wondering whether Tamayo wished him to die.
"But... how can you be so sure? You might die in this battle!"
"I am not." Isao sighed helplessly and said, "Even if I do, it doesn't matter to you, right?"
"..."
It was true, even if Isao died, it didn't matter to her, and she shouldn't have troubled him, but then again, with all of those who had loved him, was he going to leave them like this?
"You will regret it if you don't see them anymore, you know?"
Once again, Tamayo tried to persuade him.
"..."
Isao knew that this woman thought of the best for him, but he really wasn't going to die; he was going to win. If he made a comparison, it was like he was going to work at nine and then return at five in the evening. That's it. It was nothing special; it was just your everyday job.
Yet, this woman thought of this as something that would take his life.
However, Isao also didn't feel surprised.
While he thought of Muzan as nothing but just another animal to increase his power, Tamayo thought of Muzan as her nightmare, something that she should use her everything to defeat.
Moreover, even if Isao had shown Muzan's legs and arms, he knew that it was hard for Tamayo to believe that he could defeat Muzan alone.
Isao thought for a while, then took out something from his bag.
"That's it...?" Tamayo was confused by items that came out of Isao's bag.
"Bomb."
"B-Bomb?"
"Yeah, it's a napalm bomb mixed with wisteria formula."
"Napalm bomb?"
Wisteria aside, what was a napalm bomb?
The napalm bomb didn't appear until 1939, but Isao took it out, especially when he had an oil company. The use of oil might not be as widespread as fuel for a vehicle, which wasn't common in this era, and oil was mostly used as a lubricant.
Still, it didn't stop Isao from developing a napalm bomb as it was easy to make, especially when he had many memories from those lecturers that he devoured at Tokonosu University.
Many might say that he should develop a nuclear bomb, but where the hell was he going to have the technology or money for it?
Yes, he might be wealthy, but he wasn't that wealthy, and the total amount of money needed to develop a nuclear bomb was at least a billion dollars.
His wealth hadn't reached such an amount, okay?
Moreover, the napalm bomb couldn't be underestimated, especially when it could burn for so long, and when it was mixed with wisteria formula, it was as good as a nuclear bomb for the demon.
Still, it didn't mean that he was going to use it after all; he felt that he could take down Muzan with just his Nichirin weapons.
Yet, hearing the explanation of the napalm bomb from Isao, Tamayo was dumbfounded.
A bomb that would release fire forever?
Was such a thing possible?
Yet, Tamayo knew that Isao didn't lie and that, with his ability, it should be possible.
Who was this guy?
Was this guy really a deity from heaven?
Or someone from the future?
While she was confused, she also became more curious about him.
"...just what are you?" Tamayo asked.
"I am just a human."
What would he have been like if he hadn't been human?
"My time is limited, so I want to let it spark like a comet that shines brightly over everything before it disappears."
"...." Tamayo.
"That's it, don't bother me again, okay? Also, let me say it again: I won't die."
"Are you sure?"
After all, Isao brought bombs, so he might sacrifice himself, right?
"You are too obstinate. Don't annoy me."
However, Tamayo didn't listen to him and just stared at him, staying in a place, waiting for him to agree to meet his family first.
"If you don't leave, then I might attack you, you know?" Isao threatened.
Yet, instead of being scared, Tamayo snorted.
"....."
Isao blinked his eyes, then said, "I am serious."
"Show me, then."
Tamayo didn't show fear and looked at him with a provocative expression.
Isao raised his brows, thinking that a good person had always been underestimated, so he pulled Tamayo into his arms, kissing her lips without hesitation, giving her a deep kiss. Yet, instead of pushing him away, she was even crazier than him, sucking his tongue and saliva and exchanging a deep kiss with him.
At this moment, he realized that the quiet and demure Tamayo was just a disguise, and her real personality was a savage and wicked woman who would attack a powerless man.
In the beginning, he had the upper hand, but soon, Tamayo got the upper hand. Even if her body was smaller than his, she was hundreds of years older and also a married woman.
Did he think of her as a virgin that would get shy?
How could it be?
Her hands were covered in blood, and facing Isao's threat, she thought that it was cute instead of being scared, so when they parted their lips, Tamayo, whose neat hair was in a mess, smiled lustfully at Isao, who was in a daze after the kissing.
"How cute~! Do you think that I am an innocent woman who will blush at your advance~? Do you expect every woman to be pure and chaste like your lovers~? You are underestimating me, young man~!"
Tamayo really thought Isao was so cute, which made him cling to him tightly, straddling his waist. She showed off her sharp fangs and small tongue, which she stuck out as she gazed into his eyes with her demonic eyes.
This woman!
Isao was annoyed, then pulled into bed, and as expected, she also eagerly accepted his advances.
On the other hand, Yushiro was very annoyed by the slow service of the hospital.
"Dammit! Can you be fast?! What kind of slow service is this? I will give you a bad review later!"
Yushiro wanted to return as soon as possible and take the blood supply, but he could only go home in several hours.
However, in those several hours, Isao and Tamayo could do many things.
Nevertheless, the day Muzan was going to die was coming, and it was about to happen tonight.
