Not long after Haru entered the Dungeon, the Reincarnation Tower, which had copied a vast number of world coordinates, began to operate. Various information about all discovered dungeon worlds was promptly updated. Reincarnators preparing to enter the worlds were soon astonished to see that various dungeon worlds had background introductions. Although simple, this information could save their lives, especially for beginners.
The news quickly spread among the reincarnators, affecting the outside world as well.
The topic that all previously unnamed dungeons had now been clearly labeled brought greater curiosity to them, making them excited as they learned of this news. For them, the information presented by the Reincarnation Tower felt like a cheat sheet during an exam, boosting their confidence in undertaking missions within the dungeon worlds. The Reincarnator Forum was a special web platform used by reincarnators to share news and discuss dungeon worlds; of course, important information remained their secret. Currently, the Reincarnator Forum could be described as exploding, becoming a lively discussion arena, with reincarnators sharing opinions and speculations about what would happen next.
A reincarnator named Arka posted excitedly, "Have you all heard? The dungeon we previously called 'the ninja village' is now officially named 'Naruto'! What does this mean? Who is this Naruto?"
Replies immediately flooded in from various corners of the forum. A user named Seeker stated, "This is insane! I remember when we first entered this dungeon. We thought it was just a battle for resources in a ninja village. But now, it seems that's not the case!"
Another reincarnator, Demon Sword, added, "Wait, if Naruto is the center of this dungeon, then why did no one have that name last time?"
"Maybe he wasn't born at that time," another reincarnator replied. That answer quickly received approval from other reincarnators.
After confirming the accuracy of the information, various guilds and consortiums immediately began to operate and rearrange their strategies to be more directed.
Hungry Wolf was a medium guild that dominated Kanazawa. In the last dungeon, Ryouhei, one of their members, entered a world filled with giants, where humans could only hide behind walls like caged animals. However, after unintentionally knocking out a doctor named Grisha Yeager to obtain information, and from the notes and books he took from Grisha, he discovered the truth about this world. The place he was in was just an island, Paradis. Beyond it lay a vast continent with a more advanced civilization. Additionally, he obtained a serum that could turn humans into Titans. Despite knowing the risks, he boldly drank it. He became a mindless Titan, driven only by the instinct to devour humans; fortunately, here, there was only Grisha Yeager who was unconscious, so the Titan transformed by Ryouhei wouldn't eat the wrong target.
After consuming Grisha, Ryouhei gained the Titan power possessed by Grisha, the Attack Titan. From Grisha's notes, he learned that there were 9 Titans transformed by humans. Moreover, if he consumed all the other Titans and merged them, he could become the Founding Titan, capable of commanding all mindless Titans.
This meant that as long as they had enough Titan serum, they could turn humans into Titans to serve as cannon fodder.
But after searching for several months, he had yet to find any of the 9 Titans, and the timer had run out, forcing him to return empty-handed. Fortunately, since he had caused the plot to collapse by more than 50%, he could return to this world again.
Upon his return, he reported this to the guild president and requested assistance. After hearing this, the guild president's eyes lit up. He ordered many guild members ranked D and E to assist in this mission.
They made extensive preparations for the mission. A few days before they embarked, shocking news emerged from the Reincarnation Tower. After the guild leader checked the news, he found a world named Attack On Titan. He suspected this world was related to the dungeon world mentioned by Ryouhei, so he read the background of that world and finally became convinced that Attack On Titan was the dungeon world they would enter. From the introduction, he understood why Ryouhei failed to find the other Titans; it was because he had arrived far too early.
After weighing the pros and cons, the president ultimately decided to use one of the most valuable items from the Guild, the Temporal Jump Card.
The Temporal Jump Card was a special item that could be used to leap through time to a specified year. This card was a random reward from a mystery box after an individual or reincarnator team contributed to the origin power fluctuation by 25%.
However, the chances of obtaining it were very low. The card had a rarity level represented by stars ranging from 1 to 5.
A 1-star Temporal Jump Card allowed the user to jump through time for a maximum of 1 year, a 2-star for 5 years, a 3-star for 10 years, a 4-star for 20 years, and a 5-star for 100 years.
If one person used the card while about to enter a dungeon world, all other reincarnators would also be swept along with them and begin their mission in the same year.
.....
On the other hand, Haru was unaware of what was happening after he entered the Dungeon. He was currently training with other Hashira and several Demon Slayer members. Alongside sword techniques, Haru was also learning to create potions and poisons with Shinobu at the Butterfly Mansion. He had absolute memory, so of course, he made the most of it. Apart from potions and Water Breathing techniques, Haru was also studying other breathing techniques, not intending to use them himself but planning to sell them when he returned to the Reincarnation Tower.
Haru stood in the middle of the training field, the scorching sun beating down on his skin. Around him, the Hashira and other Demon Slayer members were training diligently. The sounds of clashing swords, spirited shouts, and steady footsteps formed a symphony.
Haru glanced at Shinobu, who was observing from a distance. Although she appeared calm, there was a furrow between her brows, as if contemplating something complex. Haru knew she was thinking about how to fight Doma after understanding his capabilities.
Days passed, and Haru trained hard, striving to enhance his strength before the final battle. He knew that his power was insufficient to face Kibutsuji Muzan.
One afternoon, after an exhausting training session, Haru approached Shinobu at the Butterfly Mansion. He found Shinobu mixing ingredients in a room surrounded by various potions.
"Haru, you arrived just in time," Shinobu said, smiling gently. "Today we will make pain relief potions and poisons for attacks."
Of course, the poison Shinobu referred to was not poison used to harm humans, but rather wisteria flower poison to kill demons.
Haru nodded. "I'm ready. What should we do first?"
Shinobu explained the steps in detail, and Haru observed every movement of her hands.
"Every potion has a different purpose and effect," Shinobu explained. "We need to know what we want before we start mixing."
Haru watched as Shinobu carefully selected the ingredients, noting everything in his memory.
As they worked, Haru couldn't help but ask, "Shinobu, what will you do once all the demons are eliminated?"
Shinobu was taken aback by Haru's question, as she had never thought about what she would do after the demons were gone. She involuntarily thought of her late sister, Kanae Kocho. Memories of their beautiful moments together flooded her mind, causing her expression to fall and revealing a hint of vulnerability.
"Shinobu, are you okay? I'm sorry for my sudden question," Haru asked as he noticed her condition.
"Ah... Are you worried about me, Haru?" Shinobu said, forcing her usual smile, concealing the sadness on her face.
Seeing Shinobu hide her vulnerability behind her gentle smile, Haru stepped forward and embraced her without saying a word.
He often saw Sora like this in the past after their parents had passed away, and Haru would usually hug him, hoping to provide some warmth.
Although Haru was 15 years old, his mental age was over 30, so he didn't feel awkward or think it was wrong to comfort Shinobu, who was physically a few years older than him.
Perhaps because of the warmth she hadn't felt since Kanae's death, Shinobu slowly closed her eyes and rested.
Of course, if it weren't for the good relationship and the closeness they had developed over time, it would have been impossible for Shinobu to allow Haru to embrace her, even when she was sad and in need of comfort.
....
On the other hand, Haru did not know what happened after he entered the Dungeon. He was currently training with the other Hashira and several members of the Demon Slayer Corps. Besides practicing sword techniques, Haru was also going to learn how to make potions and poisons with Shinobu at the Butterfly Mansion. He had absolute memory, so of course, he made the most of it. In addition to potions and Water Breathing techniques, Haru was also studying other Breathing Techniques; he didn't intend to use them himself but planned to sell them when he returned to the Reincarnation Tower.

"Haru, you came just in time," Shinobu said with a gentle smile. "Today we will make a pain relief potion and a poison for attacks."
Of course, the poison Shinobu meant was not for poisoning humans, but the wisteria flower poison to kill demons.
Haru nodded. "I'm ready. What should we do first?"
Shinobu explained the steps in detail, and Haru observed every movement of her hands. He felt a desire to learn more, not just about potions but also about Shinobu's way of thinking. He was curious about her thought process when crafting the ingredients.
"Every potion has different purposes and effects," Shinobu explained. "We must know what we want before we start mixing."
Haru watched as Shinobu carefully selected the ingredients, and he mentally noted everything.
As they worked, Haru couldn't help but ask, "Shinobu, what will you do after all the demons are exterminated?"
Shinobu was surprised by Haru's question, as she had never thought about what she would do after the demons were gone. She involuntarily thought of her late younger sister, Kanae Kocho. She recalled the beautiful moments they shared, and her face inevitably turned sad, revealing a hint of vulnerability.
"Shinobu, are you okay? I'm sorry for my sudden question," Haru asked as he noticed her condition.
"Ara... Are you worried about me, Haru?" Shinobu said, smiling as usual, masking the sadness on her face.
Seeing Shinobu hiding her vulnerability behind a gentle smile, Haru stepped forward and hugged her without saying anything.
He often saw Sora like this in the past after their parents died, and Haru would usually hug him, hoping to provide a little warmth.
Although Haru was 15 years old, his mental age was over 30, so he felt no awkwardness in comforting Shinobu, who was physically a few years older than him.
Perhaps because of the warmth she hadn't felt since Kanae's death, Shinobu slowly closed her eyes and rested.
Of course, if it weren't for their good relationship and the closeness they had formed over time, Shinobu wouldn't have allowed Haru to hug her, even while she was sad and needed comfort.
....
A vast valley with a river flowing through the middle, surrounded by green forests. At the edge of the river, there was a large training ground, encircled by trees that created a tranquil yet spirited atmosphere.
Haru stood at the riverbank, the gently flowing water creating a soothing sound. He was wearing a white haori, with a calm and focused expression. Around him, the Demon Slayer members gathered, excited yet slightly anxious. Giyu stood beside Haru, his expressionless face watching the members as they prepared.
"Today, we will train together to enhance your strengths. Each Hashira has different methods, and you will learn from all of us. Ready?" Haru said calmly and seriously.
"Ready, Haru!" Tanjirou replied optimistically.
"I hope it's not too hard…" Zenitsu whispered with a trembling voice.
Haru smiled upon hearing Zenitsu's worries, then continued.
"Remember, this training is not just about physical strength, but also about self-control and concentration. Giyu, please start."
Giyu nodded and then called the members to gather near him.
"We will begin with the basic Water Breathing techniques. Focus on deep breathing and your flow of energy. Try to feel the water flowing around you," Giyu said in his usual monotone voice.
They all followed Giyu's instructions. Tanjiro and Kanao trained with full concentration, while Zenitsu still looked a bit nervous.
After some time, Giyu stopped the training and let Haru take over.
"Now, we will practice facing each other. Duel with the techniques you have learned. Remember, do not use your full strength; we are here to learn."
The Demon Slayer members began to duel, the sound of clashing swords creating a dynamic atmosphere. Haru observed closely, giving directions when necessary. He watched as Tanjiro fought Kanao with enthusiasm, while Zenitsu struggled to overcome his fear.
"Zenitsu, remember, don't just rely on instinct. Try to stay calm and focus on your breathing." Haru approached Zenitsu.
"Okay, I'll try," Zenitsu nodded.
After several matches, Haru halted the training and allowed them to practice Mitsuri's method.
Mitsuri stepped forward with her ever-cheerful smile gracing her face.
"Hi everyone! We will work on your flexibility and agility! First, avoid my attacks," Mitsuri said while waving her whip. Initially, they were hit by Mitsuri's whip before they began to improve. After that, Mitsuri asked them to perform various difficult stretching movements.
"Ah..." Accompanied by cries and the sound of joints cracking, they continued to perform the movements Mitsuri requested. Fortunately, the medical staff had good skills in handling the injured.
After Mitsuri's segment was over, it was now Shinobu's turn.
Shinobu stepped forward with a gentle smile.
"... This is not just about attacking, but also about strategy and speed. You must be able to evade and strike at the right moment..." Shinobu said.
The members began practicing evasion and striking movements, many of them surprised by Shinobu's speed and precision. Haru watched, admiring how Shinobu could make the training more engaging.
"Remember, you must always be vigilant. In battle against demons, even the smallest mistake can be fatal."
The members began training with great enthusiasm, the sounds of swords and shouts of encouragement filling the valley.
After the training session ended, Haru called all the members to gather.
"Great job today. You have all shown remarkable progress..."
Two months flew by quickly. During this period, the demons were very active, attacking everywhere, but despite that, only weak demon slayer troops were sent; no Hashira were seen. This raised Muzan's alertness, as he did not know what the demon slayers were planning. Due to his cowardly nature, he was afraid to act rashly, so he only sent weak demons as bait to investigate the situation.
In the last two months, Haru had fought against the other Hashira. Through their battles, they were able to rapidly increase their strength.
Additionally, under resonance, except for Gyomei, all Hashira had awakened their Demon Slayer Marks, and Tanjiro had also activated his mark. It wasn't that Gyomei couldn't activate it; he suppressed it himself by distancing himself from the other Hashira and not training. Gyomei was over 25 years old, so if he activated the mark now, it was uncertain how many days he had left to live. Therefore, to participate in the final battle against Muzan, he chose not to activate the mark.
Haru stood tall in the training field surrounded by the other Hashira. In front of him, Kyoujuro Rengoku was ready to fight. His bright eyes looked at Haru with enthusiasm, as if reminding him that every second was precious in this training.
"Ready, Haru?" Kyoujuro asked with a smile on his face, his sword ready to swing.
"I'm ready, Kyoujuro!" Haru replied.
Haru took a deep breath and recalled all the techniques he had learned. He knew Kyoujuro was a tough opponent, but he was prepared to give it his all. With the Water Breathing techniques he had mastered, Haru began to move.
"Second Form: Water Wheel!"
Haru leaped towards Kyoujuro with a swift circular movement.
Kyoujuro raised his sword to meet Haru's attack.
"Good! But you need to be faster!" He stepped aside, evading Haru's slash before countering with a quick attack.
"First Form: Unknowing Fire!" Kyoujuro swung his sword with force, creating a blazing wave of fire aimed at Haru.
Haru quickly jumped back, avoiding the wave of flames.
"Third Form: Flowing Dance!"
Haru swung his sword with extraordinary precision, flowing like a dance of water.
Kyoujuro was forced to block the attack, raising his sword to protect himself.
"You're getting better, Haru! But I won't lose now!" He stepped forward and attacked with a flurry of strikes.
Haru felt pressured, but he did not give up. He focused on his breathing techniques, trying to infuse more energy into his movements.
"Fourth Form: Striking Tide!" He swung his sword with power, creating a wave of water sweeping towards Kyoujuro.
Kyoujuro stood firm.
"Fifth Form: Flame Tiger!" He summoned the power of fire, creating a raging flame tiger aimed at Haru, dispelling the wave of water.
The two powers clashed, creating an explosion that shook the air around them. Dust and smoke enveloped the training field, but Haru did not lose focus. He knew this was a critical moment.
"Now!" Haru shouted, expending all his remaining strength.
"Tenth Form: Constant Flux!" Haru continued swinging his sword, increasing the speed and power of his strikes; a water dragon coiled and surged towards Kyoujuro.
"Ninth Form: Rengoku!" Kyoujuro unleashed his strongest attack, trying to resist the water dragon with blazing flames.
The two forces clashed again, creating an enormous wave of energy. Haru felt every strike, every vibration, and he knew this was the moment to unleash all his abilities.
Haru gathered all the energy he had, focusing it into his final attack. "Sixth Form: Waterfall Basin!"
Haru leaped into the sky and slashed vertically, water gushing forcefully from his sword, forming a large pool of water, directing all his power towards Kyoujuro. In an instant, the water formed a powerful whirlpool, encircling Kyoujuro and attempting to pull him in.
Kyoujuro felt the pressure from the attack, but he would not back down.
"Fourth Form: Blooming Flame!" He leapt into the air, swinging his sword with blazing spirit, creating a fiery attack aimed at Haru.
The two attacks collided, creating an incredibly powerful explosion that shook the ground beneath them. Smoke and dust enveloped the area, and as everything began to settle, Haru fell to the ground, breathless.
Kyoujuro also fell, but he smiled. "You're great, Haru. You have grown stronger than before." Haru smiled back "Thank you, Kyoujuro. I learned a lot from you."
