On the other side, worried about Nezuko, Zenitsu overcame his fear and also ran into the forest.
But the forest was so large, and combined with his fear, he predictably got lost. After a bout of inexplicable anger, he encountered a spider with a human head.
"No way, it has a human face! It's a human-faced spider! What's going on? What's going on? It's a dream, right? It's a dream, right? Please, tell me this is a dream!"
Because he was too terrified, Zenitsu kept muttering to himself, trying to hypnotize himself that everything was a nightmare. That after waking up, nothing would be there, and he could even be lying on Nezuko's lap...
But no matter how crazily Zenitsu tried to hypnotize himself, reality remained reality.
After a frantic run, he arrived at the Spider Brother's dwelling. The house floated in the air, surrounded by numerous threads.
Some Demon Slayer Corps' members were even hanged by the threads, many already bald, transforming into a monstrous form.
[What is this? And it stinks! The smell is so pungent! If Tanjiro, with his keen nose, came, he'd definitely die. This smell makes my throat sore, and my eyes are about to tear up, they hurt so much!]
Just as Zenitsu was feeling extremely miserable, the floating house suddenly moved.
A giant spider with a human head slowly descended. Compared to Rui's other 'family', this Spider Brother was definitely the ugliest and most disgusting.
"So big, so big, so big!" As the Spider Brother slowly descended, Zenitsu could only repeat that word.
When he saw the Spider Brother smile at him, Zenitsu shivered.
"I! Will not! Talk! To a thing like you! Ah!" As he spoke, Zenitsu turned and ran.
"It's useless to run. You've already lost." Watching Zenitsu's actions, the Spider Brother was unflustered.
"What are you talking about? Listen, don't talk to me! I hate guys like you!" Hearing his words, Zenitsu looked angry.
"You already understand. The situation is already bad." Hearing Zenitsu's words, the Spider Brother twisted his limbs seductively.
"What do you mean?" Seeing the Spider Brother's confident demeanor, Zenitsu was uncertain.
"Look at your hand."
"Ah?! My hand!" Hearing his words, Zenitsu felt baffled. But looking at his palm, he saw it was already starting to rot, with purple poison...
"It's poison. You were bitten by a spider, weren't you... It's poison that will turn you into a spider too. Haha, in half an hour, you'll be crawling on the ground as my slave." Seeing Zenitsu's shocked expression, the Spider Brother kindly reminded him.
"Look, this is a clock. You see, when this hand reaches here, you'll turn into a spider. Before that, your hands and feet will go numb and hurt. Here, you'll feel dizzy and vomit. And here..."
Seeing the scared Zenitsu, the Spider Brother kept intimidating him. He loved seeing the despair in human eyes. The more Zenitsu was scared, the happier he felt.
Then, with malicious interest, he summoned a group of human-faced spiders to surround Zenitsu. He also noticed Zenitsu seemed very timid, easy to intimidate, and his reactions were very exaggerated, which excited him.
Then, they started a verbal fight. Zenitsu directly mocked the Spider Brother for having no friends and no lover, making him somewhat angry.
Then, as Zenitsu's hair started falling out, combined with the Spider Brother's wicked smile, Zenitsu completely fainted.
"What's with this guy? Isn't he a Demon Slayer who came to kill our family?" Watching Zenitsu yell and scream the whole time, then faint from fright, the Spider Brother was stunned.
But only after losing consciousness did Zenitsu begin to exert his power.
He activated his Breathing Technique, then used the momentum to quickly approach the Spider Brother.
Sensing something wrong, the Spider Brother spat out a stream of venom, forcing Zenitsu to abandon his attack to dodge.
'What's going on? He can twist his body in mid-air to dodge. His agility is completely different from just now!' Noticing Zenitsu could still dodge his attack in the air, the Spider Brother was caught off guard. The change was too great.
"Thunder Breathing: First Form!" Zenitsu, below, kept charging.
"All of you, jump on him!" Sensing Zenitsu's strange change, the Spider Brother didn't dare mess around this time. He quickly ordered the human-faced spiders to interfere with Zenitsu.
Then, after a series of attacks, the Spider Brother noticed Zenitsu had maintained the same charging pose.
He immediately understood Zenitsu only knew one sword technique, revealing a look of contempt.
Seeing time passing, and thinking Zenitsu was already too poisoned to move, and no longer a threat, he had all the spiders bury Zenitsu.
"Hee hee." Watching Zenitsu submerged, the Spider Brother showed a mocking expression. Just as he relaxed, Zenitsu, having charged to his peak, finally erupted.
"Thunder Breathing: First Form: Thunderclap and Flash!" Powerful lightning directly scattered the human-faced spiders surrounding him. Then, the Spider Brother, who had relaxed, panicked. He quickly returned to the air and began spitting venom at Zenitsu.
But Zenitsu, now empowered by lightning, moved at a speed the Spider Brother's eyes couldn't even track. Finally, just as the Spider Brother was about to flee, Zenitsu used his threads to launch himself and instantly killed him.
"Was I cut? Me? Was I cut? By a guy like that?" Even at the moment of death, the Spider Brother couldn't accept it. Being killed by such a weakling, when Zenitsu was supposed to die from the poison...
...
Meanwhile, Takeru naturally saw Zenitsu's outburst. So, after healing Inosuke, he stood up.
"Takeru-san, are you going somewhere?" Seeing Takeru stand up, Tanjiro asked with confusion.
"Zenitsu has already killed the Spider Brother. But he's not far from dying from the poison himself." Hearing his words, Takeru spoke softly.
"What? Zenitsu, he... where is he? Please save him, Takeru-san!" Hearing Takeru's words, Tanjiro had no doubt and directly begged Takeru.
"Including this, you already owe me a lot of favors, Tanjiro." Hearing Tanjiro's words, Takeru narrowed his eyes.
"Takeru-san, if there's anything you need me to do, I am willing to even sacrifice my life. But right now, please save my friend." Hearing Takeru's words, Tanjiro gave him a promise without hesitation.
"Remember your words. Since that's the case, let's go together." As he spoke, Takeru teleported Tanjiro with him to the Spider Brother's dwelling.
Before Tanjiro could react, an extremely pungent smell nearly made him completely faint.
"Tanjiro, Tanjiro?! Am I hallucinating?" In his drowsy state, seeing the unfamiliar Takeru and Tanjiro appear before him, Zenitsu was confused.
"Zenitsu, Zenitsu, you're so seriously injured. Is this poisoning?" Looking at the Zenitsu before him, Tanjiro helped him up.
"Tanjiro, it's really you. You finally came to find me!" Hearing Tanjiro's words, Zenitsu realized this wasn't a hallucination. Tanjiro had really come to find him.
"Zenitsu, why... you also came into the mountain, and you killed the Spider Brother alone?" Looking at Zenitsu, Tanjiro said with emotion.
"Tanjiro, I didn't run away this time. I did it, Tanjiro." Hearing Tanjiro's words, Zenitsu tightly grasped his hand.
"I see. Don't worry. With Takeru-san here, you'll be better soon." Hearing Zenitsu's words, Tanjiro quickly comforted him.
"Takeru-san, can the poison be cured?" Then, Tanjiro looked at Takeru.
Hearing his question, Takeru nodded slightly without saying much. Instead, he sensed a figure that should have been dead, which surprised him a bit.
"Healing, Purification." Then, Takeru exhaled softly and directly cast Healing and Purification on Zenitsu.
Under the dual magic, the poison in Zenitsu's body quickly receded, and his rotted palm rapidly returned to normal.
"Takeru-san, can those people be saved?" Then, Tanjiro noticed the other hanged Demon Slayer Corps' members and the human-faced spiders looking towards them in terror.
"Bring the hanged people over. As for those, they can also be saved." Hearing Tanjiro's words, Takeru gave him simple instructions.
