Five minutes after the Father Spider Demon had been killed, Natsu Rengoku and the Mother Spider Demon agreed to go on their separate ways.

Natsu ran back towards his friends. He told them that he would stop the spider demons from killing anymore people. "Hey, Ozaki! Inosuke! I'm back!"

"Natsu. You made it." Ozaki said as she saw Natsu approach her and Inosuke.

"What the heck took you so long?" Inosuke asked.

Natsu looked at Inosuke for a second, then turned to Ozaki and noticed something different. "Ah!" Natsu looked at Ozaki's head. "Did you do something, Ozaki? You look a little different." Natsu noticed that Ozaki's hair.

Ozaki looked at Natsu's index finger, which was pointing towards his head. "Hm?" Her eyes looked upwards. "Oh. You're talking about my hair. You must've noticed that I fixed it. It was a little out of place, so I untied my hair and redid it." she placed her hands on top of her black hair and combed it back a bit.

"You look better with your hair fixed." Natsu gave Ozaki a smile and thumbs up.

"Thanks." Ozaki's responded. Her eyes looked downwards to her left and tried to hide her blush.

Inosuke let out steam through his boarhide snout. "Hey..." he then shoved Natsu's left shoulder, catching his attention. "Did you kill the demon or not?"

"The Mother Spider-Demon?" Natsu thought of a way to tell Inosuke and Ozaki the news about the Mother Spider Demon. "Well, I have to be honest with you..."

"Hm?"

Both Inosuke and Ozaki stood and looked at Natsu as he told them what had happened. It took Natsu a minute and a half.

Ozaki gasped then cupped her mouth. "One of the Twelve Kizuki is on this mountain?"

"Mm-hmm." Natsu nodded. "But I believe we can take him down if we all work together."

"But, there's only three of us. There's no way we can beat one of the Twelve Kizuki on our own..." Ozaki counted herself, Natsu and Inosuke. She was doubting her own abilities.

"Oh, yeah. I came here with three other people on this mountain." Natsu noted as he then thought about Tanjirou, Nezuko and Inosuke.

"You have friends?"

Inosuke had gotten mad and stomped his right foot on the ground, angrily. "What! You let her go?"

"Listen, Inosuke-"

"She's a demon who's killed people!" Inosuke pointed at Natsu. "And you were supposed to take her out! We agreed on it!"

"I know that! But, she was also suffering from the harsh abuse that the other Spider Demons were giving her. So I-"

Inosuke's right fist collided with Natsu's chest. "That's no excuse for you not to kill her."

Natsu bent on one knee and started coughing after taking a punch in the same area that the Father Spider Demon had punched him.

"Natsu!" Ozaki cried as she watched Inosuke punch him.

"Huh?" Inosuke was a little confused as he watched Natsu cough a bit. Usually, Natsu would usually be one or two steps ahead of him. But seeing Natsu on the ground like that, he was confused. "Hey. Why are you acting beat up all of a sudden?"

"Sorry, guys. Some wind got knocked out of me, earlier." Natsu said as he looked to Inosuke with one golden eye closed. He was referring when he fought the Father Spider Demon about fifteen minutes ago.

"You mean with one of the Spider Demons?" Ozaki questioned.

"Right." Natsu slowly stood on his feet.

As Inosuke watched a partially vulnerable Natsu slowly get up, a lightbulb had suddenly appeared over his head. He had thought of an idea and silently grinned within his boarhide.

"Gotcha!" Inosuke jabbed Natsu's chest.

"Ow!" Natsu fell back on one knee. "Inouske, what are you doing! Ow!" Natsu grunted as he felt more pain from Inosuke's multiple jabs.

"What does it look like! I'm beating you, Natsu!" Inosuke replied while delivering multiple jabs to the ribs. "And once I do, I'll become the strongest Demon Slayer there is! Hahaha!"

"That's not fair, Inosuke!" Natsu said as he tried to block his jabs with his arms.

"Hahaha! I'm gonna beat ya! I'm gonna beat ya!" Inosuke yelled in a positive manner while continuing to throw multiple jabs.

"Stop it!" Ozaki yelled as she slapped Inosuke's boarhide, causing it to spin rapidly to the right. "Can't you see that he's hurt? You're only making his wound worse!"

Inosuke stopped his boarhide from spinning, then turned his attention Ozaki, who seemed a bit mad. "You... you wanna fight me, instead?"

Ozaki grunted as she watched Inosuke pull out his dual Nichirin swords.

"Fine. You and me. Let's go-" Before Inosuke could take a step towards Ozaki, Natsu quickly grabbed Inosuke from behind and placed him in a Full-Nelson lock. Inosuke dropped his Nichirin swords. "Huh? What the-"

"No, Inosuke! You can't harm girls!" Natsu yelled as he continued to grapple Inosuke.

Ozaki took a few steps away

"Huh? She struck me!" Inosuke protested as he continued to fight against Natsu's grapple. "Let go!"

"I know, but still! You can't hurt girls! She's also a Demon Slayer, like us." Natsu stated tightened his grip.

"I didn't see her take the whatchamacall Exams with us!" Inosuke stated as he still fought against Nats's grapple.

"There are other ways to become Demon Slayers, than taking the Final Selection Exams. But we can't focus on that right now! We need to hurry find Tanjirou, Nezuko and Zenitsu-so we can defeat one of the twelve Kizuki!" Natsu continued to grapple Inosuke for another ten seconds, until...

"Okay! Okay! You win! Just let go of me!" Inosuke yelled as he realized he couldn't break free from Natsu's grapple. For another three seconds, Natsu let go of Inosuke from his grapple. Inosuke panted, heavily and lied his hands on his knees. "Alright... fine." He picked up his Nichirin swords in the next five seconds.

"Can you use you special awareness technique to search for our friends?" Natsu asked.

"Yeah..." Inosuke replied as he withdrew his dual Nichirin swords.

Meanwhile...

The Daughter Spider Demon had leaped from tree-to-tree for almost ten minutes. She was in an urgent rush to find Rui, one of the Twelve Kizuki. She looked below spotted Rui strolling through the woods with a net of webs in his hands. She gasped in relief and jumped downwards from a high tree branch.

"Rui! Rui!" Daughter Spider Demon yelled as she approached Rui. She looked at his backside. "There's something I have to tell you!"

Rui slowly turned half his body towards the Daughter Spider Demon.

"The Demons Slayers are getting closer! They killed Father and probably big brother, too!" the Daughter Spider Demon had informed Rui.

"And what of mother?" Rui asked slowly.

The Daughter Spider Demon clenched her teeth as she thought of the Mother Spider Demon. "Mother... she betrayed us for the humans!"

"How unfortunate. I will deal with her personally, once I find her. Then I will replace her with a new mother." Rui said in an emotionless tone.

"Sh-should we run away, Rui?" the Daughter Spider Demon asked in concern. Without any notice, the Daughter Spider Demon's eyes had deformed, turning back into the eyes she once had. Her white sclera turned black and her light aqua pupils turned red again.

Rui glared at the Daughter Spider Demon with anger and disgust as he spotted her regular demonic eyes. "Who... who told you that you can look like that again..."

The Daughter Spider Demon gasped as she noticed Rui had gotten angry.

Within the next four seconds, Rui used his sharp webs and cut her face without any remorse.

"Gyyaaaah!" the Daughter Spider Demon screamed in agony. She fell on her knees and gripped her face, which was pouring blood. It had gushed from her face.

"I believe I have told me to never appear before me with that face again..." Rui said as he stood over the Daughter Spider Demon.

Ten seconds after the Sister Spider Demon had screamed, two Demon Slayers such as Tanjirou Kamado and Zenitsu Agatsuma had approached the Spider Demon siblings. They were Tanjirou Kamado-with Nezuko inside of his box. And next to him was Zenitsu Agatsuma. They both gasped while watching Rui torture the Daughter Spider Demon.

Rui glanced at the two Demon Slayers. "What are you doing? This isn't a play."

Tanjirou grunted and gripped his black Nichirin sword.
