Assault

As the man lunged towards his wife, intent on biting her, Hiroto sprinted forwards and pushed the man away. Tanjiro then followed up and tackled the man onto the ground, pulling the man's arms behind his back.

Muzan's eyes narrowed as he saw the hanafuda earrings on Tanjiro, then looked towards Hiroto's wrist with the bracelet.

Hiroto pushed the crowd back as he yelled out, "Everyone! This man is sick, please step back!"

The crowd started talking under their breaths, "What is that kid doing to that man?" "Sick? Is it infectious?" "Where's the police?" Various voices sounded out around them.

Muzan started turning around and walked away with his family, "It's dangerous here, let's leave." He said to his family.

Hiroto clenched his fists as he looked on. There were too many civilians around him to do anything, one wrong move and Muzan could infect more than just one.

Tanjiro turned and yelled out, "Muzan Kibutsuji!! I'm not letting you getaway! No matter where you go!" Muzan's face turned into a scowl hearing those words, ignoring them and continued walking.

"Tanjiro now's not the time," Hiroto said walking up to him.

"What the hell are you doing?!" 3 police officers yelled out as they ran over. "Is it a drunk?"

"Oi, kid. Step away from that person." The police officer said.

"I can't, please bring some restraints!" Tanjiro cried out.

"Shut up and step away," The police officer yelled, reaching out to grab Tanjiro.

Hiroto stepped up and blocked the officer before he could get close. "Listen, this man is dangerous to the people around, get some restraints or else things could get much worse."

"Get out of my way kid if you don't want to be arrested!" The police officer yelled.

Tanjiro yelled out, "I can't let go of this person, I don't want him to kill anyone."

"Enchanting blood. Aroma of Visual Fantasy."

The next moment, the area started to fill with beautiful flower patterns surrounding them. "What the hell is this?" One of the police officers shouted.

Hiroto looked to the side and saw Tamayo walking up to them with Yushiro in tow. Tamayo's arms were bleeding from being forcefully scratched by her nails to activate the blood art.

Tanjiro looked up, both in anxiousness and surprise from the scent of the blood the women gave off.

"Tamayo-san," Hiroto spoke up first.

"Allow me to lend you a hand," Tamayo said, healing her wounds at the same time.

"What? Brother, you know her?" Tanjiro asked after hearing Hiroto's response earlier. "But she's…"

"I know, she's a Demon. Don't worry, she's different from the others." Hiroto said, reassuring Tanjiro. Turning to Tamayo, he continued.

"We would appreciate the help, can we go back to your home?" Hiroto said.

"Yes, Yushiro please take that man," Tamayo said before Yushiro walked forward and knocked the man out by hitting a pressure point. 'Watching the lovely Lady Tamayo's work has made me inspired. I hope she praises me for this.' Yushiro thought while keeping on a poker face.

"What about these people?" Hiroto thought as he looked around.

"No need to worry, they have been put under an illusion and will forget everything that happened here," Tamayo responded. Hiroto nodded his head before saying, "We'll meet you back at your home. We need to go get someone first."

Tanjiro's eyes widened as he spoke out, "Ah! Nezuko!"

[In a secluded alley]

Muzan was standing next to 2 bodies covered in blood, with the third having turned into a puddle at his feet. Snapping his fingers, three Demons immediately appeared and crouched down behind him.

"I want you to go bring me the heads of the boy with the onyx bracelet and one wearing hanafuda earrings." Turning back slightly, under his sharp red gaze, he continued, "Understood?"

"As you wish," the three Demons said simultaneously before disappearing from their spot.

Standing in place, a deep killing intent leaked out of Muzan as the face of a man with long red hair and a black mark on his forehead appeared in his mind.

[Udon stand]

Running back to the udon stand, Nezuko was seen still sitting with her eyes closed. Walking up to her, Hiroto patted her head and turned to look at the bald man before expressing his gratitude.

The bald man turned to Tanjiro and shouted out, "Now, listen to me! Here's the deal…" The man yelled at Tanjiro, with a vein bulging on his bald head. Tanjiro stood there stiffly as the bald man continued yelling.

"My point is this, okay? It's not about the money! Your brother paid for that! What I can't forgive is your lack of intent to eat my udon, all right?!" The man continued yelling with his eyes closed.

Hiroto ignored this as he started playing with Nezuko's hair.

"I'm so sorry! Please serve me another bowl!" Tanjiro said bowing.

"Ok!" The man said, "But that girl has to eat one too!" Nezuko turned to the man, with her eyes turning to the black dot in confusion.

"Ah sorry, my sister can't eat udon. She's Uhm. Allergic. To. Udon…" Hiroto said, making up the lie.

"Huh? Is that even real?" The bald man asked in doubt.

Tanjiro then said, "I'll eat her portion! I'll have two bowls!"

"Uh, okay." The bald man said. Not long after, two bowls of udon noodles were made, and Tanjiro started eating with speed.

"Wha-" The man's jaw was opened wide seeing how fast Tanjiro consumed the udon.

Finishing his second bowl, he yelled out. "Thank you very much for the meal!"

"All right! As long as you understand." The bald man said.

The three siblings then walked away as Hiroto led them to the same dead-end where the illusion was, thinking to himself. 'Are all bald men that stubborn?' *Achoo!* A loud sneeze could be heard from far back.

As they came to the dead-end, Tanjiro looked around questioningly. Hiroto proceeded to walk forward, while holding Nezuko's hand, through the wall.

"Wha!" Tanjiro exclaimed in surprise. Poking his head out, Hiroto said: "Come on, before someone sees you." Hiroto retracted his head back again.

Tanjiro then stepped through the wall and came across the same sight as Hiroto once did at the start. A large western-style house, surrounded by sakura trees. As they walked up to the front door, Yushiro opened the door and looked at the tree. Nezuko flinched and tensed up, narrowing her eyes.

Putting a hand on her back, Hiroto reassured her. "It's alright, he won't hurt us. I think." Hiroto whispered that last part.

Twitching his eye, Yushiro said, "Come on, Lady Tamayo wants to see you three. Especially that eyesore." Yushiro pointed towards Nezuko.

*snap* Hiroto put on a fake, but menacing smile as he asked Yushiro. "Who did you call an eyesore just now?"

"He-" Before Yushiro could finish his sentence, Hiroto already drew his katana and placed it on his neck.

"I'm sorry, but did you say something?" Hiroto said with a smile.

*gulp* "No… nothing." Yushiro stuttered.

"Must have been my imagination. Let's go in guys." Hiroto said dragging the two in. Yushiro stood by the door with sweat forming on his forehead. 'So overprotective.' He thought to himself.

Walking into a doctor's office, Tamayo was sitting on a stool as she waited for the three. "Where's the man from earlier?" Tanjiro asked.

"Unfortunately I have to keep him restrained in the basement," Tamayo responded before standing up with her white apron on.

"I'm not sure if your brother has told you about us, my name is Tamayo. That boy there is Yushiro. I hope that you can be friends with him." Tamayo said as Yushiro looked down on the ground containing his frustration at Tamayo's last remark.

*pfft* Hiroto off to the side was covering his mouth looking around, trying to control his laughter.

Walking to a side room, Tamayo beckoned them, "This way please." Taking off her wipe apron.

Walking into the living room lit by candles, Nezuko immediately laid down flat onto the tatami covered floor. "Mmm,'' She muttered satisfactorily.

"Hey! Nezuko, that's bad manners!" Tanjiro said.

"It's alright, please make yourself at home," Tamayo said.

Seated on the ground, Tamayo started, "We met your brother yesterday night when he was interrogating a Demon about the Demon's curse and how they could cure it. I approached him because his goals were different from other Demon Slayers. He wanted to find a cure for his little sister while also hunting down the man who turned her into one. Muzan."

"I was going to tell Hiroto that I thought of a way that we could cure Nezuko," Tamayo said. Listening to her words Hiroto and Tanjiro both perked up.

"Yesterday you said that it would be too hard to find a cure? What changed?" Hiroto asked.

"The number of research samples," Tamayo said. "To develop a cure, I would need the blood of those closest to Muzan to further research and analyze the curse and find a way to reverse it. But, this would mean asking you to collect the blood of those closest to him. From Demons who might be on the same level as Muzan, they are incredibly dangerous." Tamayo concluded.

"I would also need a sample of your sister's blood to study with. With your permission." Tamayo added. "I would have asked you to perform two requests. The first is to collect the blood of the Demons closest to Muzan, and the second is to allow me to study Nezuko's blood."

"If you were to be able to develop this cure," Tanjiro said. "Lots of other people will be saved, too, right?" Looking up at Tamayo and smiling.

Tamayo was stunned by his answer, before smiling. Tanjiro blushes while Hiroto smiles at his brother's words. "Still as kind as ever huh?" Hiroto said, ruffling Tanjiro's head.

*grrrr* Yushiro started growling seeing Tanjiro blush. In the next moment, however, his eyes widened in surprise as the paper talisman he stuck up before was torn apart by a force.

"Get down!" He yelled out before rushing to cover Tamayo's body. Hiroto quickly reacted and dove to the ground, pulling Tanjiro with him.

*BOOM* *Crack* Smash* Two Temari balls crashed through the wall of the house and started bouncing around the room destroying the furniture. The balls were recalled by outside, as 3 Demons stood looking at the collapsed wall.

"Hahaha" "Did you decide to kill them now?" "Vindictively of course!" The Demon holding the Temari balls said before throwing them again "Hahahaha!"
