Chapter 100: Don’t Underestimate These Eyes
“Don’t kill them?”
Jorogumo was initially confused, but she quickly understood the benefit of this approach.
There were too many enemies surrounding them, and even with both a familiar and a puppet protecting him, Fang Bo couldn’t entirely avoid taking damage.
After all, his agility was only 5 points—once the enemies got close, it was hard for him not to get hit.
Fortunately, Yoriichi Zero’s combat prowess was astounding. Against anything weaker than an Upper Moon demon, a single round of attacks was usually enough to finish them off.
As for Fang Bo’s dwindling health, he could simply use his plundering ability to heal, and the victims would be the demons lying on the ground with their limbs cut off.
That’s why he instructed not to kill these small fry; they were just walking blood bags, after all.
Looking at the demon that had just clawed him, Fang Bo motioned with his finger. His puppet raised its dual swords to block the demon’s attack, then twisted its body and sliced through two nearby demons.
[Yoriichi Zero’s slash hits, dealing 38+62+48+30 points of critical damage]
The explosive output instantly killed two demons. The puppet then returned to its master’s side, effortlessly taking down the demon that had just launched an attack.
With the addition of the newly acquired epic-level *Bloody Twin Scythes*, Yoriichi Zero’s attack power had surged dramatically, now exerting enough force to rival that of a Hashira-level fighter against demons.
Once Fang Bo’s health was fully replenished, only a few wailing demons remained, while the rest had been wiped out.
“So, where should I head next?” Fang Bo pondered for a moment.
Given the peculiar nature of the Infinity Castle, his team had already set ground rules before entering.
This battle wouldn’t be about equally sharing rewards—everyone would rely on their own abilities. They could claim loot for themselves or work together, depending on the situation.
To maximize his gains, the best option would be to help out one of the story characters. Not only would he have help in battle, but he could also keep all the loot for himself. It was certainly better than teaming up with other Reincarnators.
Everyone, including Fang Bo, had the same objective: find a main character from the plot to assist. Only if that wasn’t possible would they consider cooperating with each other.
The next question Fang Bo faced was deciding which Upper Moon demon to target.
“One step at a time.”
Just as he was about to leave, another large group of enemies appeared, clearly intent on stopping him from moving forward.
Sighing, Fang Bo resigned himself to clearing out this new batch of small fry before continuing.
Elsewhere, a pile of corpses lay at the feet of the ninja, Darren.
A few days prior to setting off, the group had purchased new poison concoctions from Shinobu Kocho. These potions, combined with Jorogumo’s venom, could effectively suppress cellular regeneration.
That’s why the demons he’d killed hadn’t disintegrated into ash.
“This poison really is effective,” Darren muttered, gazing at his venom-coated kunai with admiration. Truly, you get what you pay for.
Honestly, before entering this world, Darren had never imagined that he would face a world mission so soon.
Thinking about that mysterious temporary teammate, Darren couldn’t help but speculate—who exactly was Fang Bo?
He didn’t know how Fang Bo had triggered the world mission, nor did he understand the mission’s core. He just knew his teammate was extremely mysterious.
Considering that, after this mission, the group planned to take down a research institute in the real world, Darren realized it would be his best chance to learn more about Fang Bo.
“Once we’re in the real world, you won’t be able to hide anything anymore.”
Suddenly, Darren stopped, spinning around with his Sharingan fixed on the black lightning streaking toward him.
**Thunder Breathing, Second Form: Rice Spirit!**
Five consecutive lightning-fast slashes formed as the new Upper Moon demon dove toward him like a falcon.
If Fang Bo had been the one facing this, he wouldn’t have been able to dodge even one strike. But for Darren, who possessed the Sharingan, these attacks weren’t beyond his ability to read.
Dodging the overhead slash by crouching, Darren flung several shuriken in return, accurately hitting the demon’s right arm.
The demon was a fanged man with black tiger stripes across his face—Kaigaku, Zenitsu’s senior, also known as the “Disgrace of the Upper Moons.”
Now that the main protagonist group was sidelined, Darren found himself confronting Kaigaku head-on.
Glancing at the shuriken embedded in his arm, Kaigaku scoffed, “I didn’t think the Demon Slayer Corps still played with such childish toys.”
“Little shurikens like these will never—”
**Boom!**
Before he could finish his sentence, the shuriken exploded, blowing off his arm.
Humiliated and in pain, Kaigaku swung his blade furiously at Darren.
**Thunder Breathing, Third Form: Thunder Swarm!**
“So fast!” Darren’s pupils dilated as he heightened his focus.
He barely dodged most of the attacks, though a deep slash appeared on his chest, cutting down to the bone.
Darren had figured it out—Kaigaku’s swordsmanship relied on sheer speed.
Despite being an Upper Moon, Kaigaku was still beatable. As long as Darren could track his movements, it wasn’t impossible to defeat him one-on-one.
“I need to focus even more,” Darren reminded himself.
Kaigaku laughed when he saw Darren’s struggle. “What a joke. You’re supposed to be a swordsman of the Demon Slayer Corps, and yet you haven’t even heard of *Thunder Breathing*?”
“Thunder Breathing is known for its extreme speed—there’s no way you can follow it with your naked eyes.”
“Looks like the Demon Slayer Corps is getting weaker with every generation.”
Kaigaku was growing bored. He didn’t want to waste time with an idiot like Darren.
Having just become an Upper Moon, Kaigaku needed to earn Lord Muzan’s favor by killing a few Hashira who had infiltrated the Infinity Castle.
“Time to send you to hell,” Kaigaku sneered as his body crackled with black lightning.
With the violent thrust of his lightning-infused blade, he launched a rapid, nearly invisible attack.
**Thunder Breathing, Fourth Form: Distant Thunder!**
Just as Kaigaku had said, such an attack was indeed difficult to track with the naked eye. Unless one could access the Transparent World, or had deep knowledge of the technique, dodging it seemed impossible.
However, Darren, relying on his advanced intuition, narrowly dodged the lightning-fast thrust.
“Huh?” Kaigaku was annoyed. How did this guy manage to dodge?
Where was his Upper Moon pride if this guy kept evading his attacks?
“You won’t dodge the next one, kid.”
**Thunder Breathing, Fifth Form: Heat Lightning!**
The intense heat from the lightning made Darren feel uncomfortable. His health dropped again, a result of the blood demon art’s added effects.
But in terms of the sword strike itself, Darren once again managed to avoid the hit.
At this moment, Darren could feel his heart racing, especially around his eyes, where an indescribable sensation began to form.
There was no time to focus on the feeling—nor time to take any healing potions—as Kaigaku’s next attack was already upon him.
“This time, you’re definitely dead.”
Kaigaku roared, releasing countless lightning-shaped slashes from his body.
**Thunder Breathing, Sixth Form: Rumble and Flash!**
This was his ultimate technique. It was impossible for Darren to evade—no one could see through the attack with the naked eye.
“Finally, it’s over…”
As the dust settled, Kaigaku noticed something odd—his arm still hadn’t regenerated.
“Poison, huh?”
Kaigaku had heard from Nakime that the enemy had developed a new type of toxin, and it seemed that the kid in front of him was also equipped with it.
Feeling the effects in his body, Kaigaku estimated that the poison would only last for about seven or eight minutes. After that, his arm would regenerate.
“Humans… they always find some new tricks.”
Just as he was about to turn and leave, Kaigaku froze in place. He sensed something familiar—an enemy’s presence, one that he had encountered before.
Slowly turning back, he seemed to see a pair of blood-red eyes through the thick smoke in front of him.
That ominous aura made even Kaigaku, a demon, shudder.
“Is that it?” Darren stepped out from the smoke, his blood-red eyes now adorned with three rotating tomoe in each.
In the next instant, Kaigaku suddenly realized that the scene around him had changed.
He found himself in a place filled with the sounds of birds and the fragrance of flowers—a beautiful setting, but it made him instinctively take a few steps back.
Not far ahead stood an old man with white hair, his eyes filled with disappointment as he gazed at Kaigaku.
That old man was none other than Jigoro Kuwajima, the former Thunder Hashira and the mentor of both Kaigaku and Zenitsu.
“No… You should be dead. Where am I?!”
Kaigaku panicked, unable to face the look of disappointment in the old man’s eyes.
No matter how hard he tried, he couldn’t escape this illusion.
Everyone, regardless of their will, harbors some deep-rooted fear within their hearts.
Years ago, Kaigaku encountered Upper Moon One, whose overwhelming strength was beyond anyone’s reach. To survive, Kaigaku willingly became a demon.
Kaigaku had always believed he made the right choice. He had fought for the Demon Slayer Corps until the last moment. Who had the right to judge him?
But seeing his mentor again brought back all those memories, especially the disappointment in his eyes, which nearly broke Kaigaku’s spirit.
“No… It wasn’t my fault. I wanted to kill the enemy too!”
“It’s you! You wouldn’t teach me all the techniques. If I had learned them all, how could I have failed?!”
“Master, you were biased! Zenitsu is a weakling—I am the true heir of Thunder Breathing!”
“I… I didn’t want to eat people, but I didn’t want to die either.”
“Haha, this power is something you’ll never understand. I will become the strongest wielder of Thunder Breathing.”
Kaigaku alternated between sobbing and laughing, completely lost in the illusion.
In the end, he spilled all the thoughts buried deep within him and saw a glimpse of his mentor’s eyes softening with calm acceptance.
“I…”
No one knew what he wanted to say in his final moment, because when the vision faded and reality returned, Kaigaku’s head had already been severed by Darren’s kunai.
The **Naraku Seeing Technique** manifests the deepest fears of the target’s heart. The greater the fear, the stronger the impact of the illusion.
Even Darren hadn’t expected that a powerful Upper Moon like Kaigaku would be completely unable to resist the genjutsu.
It just showed how intense Kaigaku’s inner fear had been.
Touching his newly evolved eyes, Darren’s expression was grim.
The evolution to a three-tomoe Sharingan required continuous energy consumption, and the use of the illusion just now had nearly drained his mental strength.
It was sheer willpower that kept him standing.
“I… I need to rest for a bit.”
Finding a quiet place, Darren consumed one of the medicine packs he had exchanged beforehand and sat quietly, waiting for his energy to recover.
In one corner of the Infinity Castle, the first battle against an Upper Moon had concluded.
The victor: Darren!
