Leaving a mark on this world

"You want me to become bait for Muzan?" 

Before even Tamayo said her thoughts, Yushiro, who was on the side, couldn't control his emotions. "How dare you propose such a thing, bastard?!" Even if Isao was powerful, so what? 

At this moment, Yushiro's temper couldn't be stopped anymore! 

Using Tamayo as bait to pull such a dangerous demon, don't be kidding! 

If Tamayo died... then... then...

"Yushiro, be quiet!" 

However, unexpectedly, Tamayo scolded Yushiro. 

"Ta-Tamayo-sama...?" 

Yushiro was confused by Tamayo's reaction. 

"Please tell me your plan," Tamayo said with a solemn expression. 

"Tamayo-sama!" 

Yes, even if Tamayo didn't say it directly, it was easy to tell that she agreed to become bait for Isao to draw Muzan out. 

If it had been before, Tamayo definitely wouldn't have dared to say this, but it was different now, especially after she got Nezuko's blood and got to know Isao. 

Nezuko's blood was special, and unlike any other demons that Tamayo had seen, Nezuko was so special that it wouldn't be weird that Nezuko would be able to walk under the sun soon. 

Or rather, Nezuko would escape Muzan's control and return to being a human by herself! 

Frankly, Tamayo wasn't sure why it happened, but she could only say that it was all due to Nezuko's special body or something else that she didn't know. This was probably related to Isao's secret, but since he didn't even tell his woman, it was impossible for her to know about his secret. 

Yet, due to Nezuko's blood, Tamayo was able to create a special drug that could turn a demon into a human and also allow her to escape from Muzan's control. 

Yes, at this moment, whether it was Tamayo or Yushiro, they had escaped the Curse of Muzan due to Nezuko's blood, so even if they saw Muzan, then that bastard definitely wouldn't be able to kill them with this curse. 

While this was part of the reason, the ultimate reason Tamayo could easily agree to become bait was Isao. 

Isao Iinuma. 

This young man was incredible, or rather, Tamayo even wondered whether Isao was the god who descended from heaven to help humanity. This might seem exaggerated, but when she heard Kie tell the story of Isao, she couldn't help but think so. 

Not only did Isao need a glance to learn any breathing styles, but he could also develop many businesses and unique technologies. More importantly, his dream was great, as he wished to make everyone able to eat well and learn knowledge. 

If the Demon Slayer Corps, even the strongest one, Yoriichi Tsugikuni, only thought about defeating Muzan and all the demons, then Isao thought about the distant future, the world where Muzan and all the demons were no longer around. 

While such a world couldn't be seen by anyone, hidden deeply by a murky puddle, Isao could see it. He was the one who led everything. He was the light and the one who led everyone, like a prophet who led everyone out of the dark age. 

If Isao knew what Tamayo was thinking, he would give a thumbs-up since no one had misunderstood him anymore. He was a good guy, to the thought, and all he did was for everyone! 

Isao definitely didn't do anything due to his selfishness or any other things. 

Everything he did was for justice! 

Moreover, Isao's power was clear to all. 

Whether it was Tamayo or Yushiro, they couldn't handle him, and if Isao wished them to die, there was nothing that they could do, so Tamayo knew that she could only agree instead of rejecting. 

Or rather, she didn't have any choices at all! 

So, once again, instead of a light, Isao was simply so evil and pitch-dark that they swallowed any lights and hoped in the surroundings. 

Nevertheless, as Tamayo had accepted his request, Isao thanked Tamayo. "Thank you, so I will explain everything to you." 

Though, whether Tamayo or Yushiro were dumbfounded when they heard "thank you" from Isao's mouth, they listened to Isao's plan carefully, from the beginning of how Kagaya would use himself as bait, Muzan's cowardly nature, and also how Muzan knew nothing about their relationship. 

Still, Isao's plan was simple, and that was just to let Tamayo walk around; he met Muzan by accident, leading Muzan into this house before he surprised Muzan with his presence and then had a final battle. 

That's it. 

Only...

"...you are going to fight Muzan by yourselves?" Tamayo asked with a doubt. 

"Yes." Isao nodded. 

"..." 2x

"Are you sure? Can you really defeat this guy? If you can't defeat him, then you and Tamayo-sama will die!" 

At this moment, Yushiro understood that Isao had not only bet Tamayo's life but also his own. 

This guy was a nutjob! 

Did Isao not care about his life at all? 

Moreover, Yushiro also knew that this guy had many women and had made most of them get pregnant, which made him so wary of Isao, afraid that Isao would make a move on Tamayo, yet he didn't expect that this scumbag would be ready to give his life to fight Muzan. 

"I do." Isao nodded. "I want to make a world without a demon, after all. I am going to become a father soon, so isn't it normal for me to wish a peaceful world for my children? Moreover, I have a "Demon Slayer Mark," I can't live so long." 

"Demon Slayer Mark?" 2x

Isao then explained the centipede and red spider lily mark on his neck, telling them what it meant to have this mark, and also told them that he would probably die before 25. 

"...." 2x

"So, before that, I want to erase the demon from this world." 

Isao looked at Tamayo and said, "I am ready to bet myself to erase Muzan, so you don't have to worry. I will kill him, and you won't die since you are with me." 

Tamayo looked at Isao with a complicated mood and understood why so many women wished to be impregnated by him. She bit her lower lip, then looked at him with a determined expression. "You underestimate me. To kill Muzan, I will do anything." 

Her hatred towards Muzan wasn't something that could be described by mere words. 

Her husband, children, and all of those related to her. 

Every morning, whether she tried to fall asleep, she would see their corpse, asking her why she killed all of them. During her hundreds of years of life, she had never tried to fall asleep as she was afraid to see their bloody expressions that asked her with hatred. 

If she could kill Muzan, then she would do anything! 

"Good." Isao smiled softly and said, "Follow my lead. Be obedient, and don't mess up. Moreover, you don't need to worry since I won't let you die, especially when I still need you to cure Nezuko." 

"...yes." 

Yet, would you be prepared to die?

Tamayo didn't dare ask that question; she only kept that question inside her heart. 

Still, with his last words, Yushiro knew that Isao wouldn't let Tamayo die. 

Nevertheless, Yushiro would probably wish to die since the woman he loved the most would—

Anyway, with all of that, the death of Muzan was near.
