Ren Isana allowed himself to continue plummeting. Once he identified which world he was currently in, his panic vanished. Moreover, this world seemed to be in the midst of its final decisive battle, considering the fight had reached the Infinity Castle.
"Witness the roar of the sun!" A brilliant light suddenly erupted from the falling Ren Isana. He descended like a literal sun falling from the heavens. The numerous demons engaged with the Demon Slayer Corps were instantly reduced to ash the moment they were touched by the solar radiance.
Ren Isana's voice carried clearly into everyone's ears. In that moment, everyone witnessed a sun falling from the sky. With his appearance, every demon within the Infinity Castle was incinerated into nothingness.
This sudden turn of events caused Muzan's pupils to constrict. He couldn't help but roar in fury, "Nakime! Did you just pull the sun inside?!"
Was this some kind of joke? What exactly had Nakime brought in? A sun? You have to be kidding me! At this moment, Muzan desperately wanted to flee, but it was already far too late.
The members of the Demon Slayer Corps were overjoyed by the sudden appearance of this sun. Although they didn't understand what was happening, they knew this was a golden opportunity. The time to slay Muzan was now!
Without needing orders, everyone fighting him surged forward. As long as they could pin Muzan down, he would likely be annihilated by that sudden sun.
"Nakime, teleport me out of here, now!" Besieged on all sides, Muzan felt the cold hand of death on his shoulder. A master of survival, he knew that if he didn't run now, he would never get another chance.
"Muzan-sama... Argh!" Nakime tried to act, but a wave of scorching heat surged over her. In an instant, she was reduced to ash, vanishing within the Infinity Castle.
If he actually let them escape, wouldn't Ren Isana's arrival be for nothing? Watching Nakime melt instantly under the [Sun], terror filled Muzan's eyes. Why was there a sun in this place?
As Muzan's thoughts raced, the [Sun] descended. His body began to melt, and the intense agony forced a wretched scream from his throat.
"Damn it! Damn it all! Nakime, you useless wretch!" The solar burning forced Muzan to shriek in pain. Even as he died, he couldn't understand how Nakime had done it. How on earth had she managed to pull the sun into this space?
Ren Isana landed gracefully opposite the Demon Slayer Corps, his body still radiating a fierce, burning light. Under the radiance emitted by Ren Isana, Muzan was completely reduced to ash.
The Demon Slayer Corps was still quite dazed. They had no idea what had just happened; a sun had suddenly dropped in and turned Muzan into dust. It was utterly surreal.
Everyone's gaze fixed on Ren Isana. *Is this a god? Has the Sun God manifested?* The crowd was filled with confusion and wonder.
Ren Isana's figure slowly became clear. Looking at the now-vanished Muzan, he felt a sense of irony. The person who had pulled him in had certainly done a 'fantastic' job.
Standing before the crowd, Ren Isana sensed the surrounding space. Although this world was quite low-level, this sub-space was actually rather impressive. It would make a decent landmark.
Most importantly, this spatial passage had actually opened right in front of Ren's dormitory? And the other side connected to the Infinity Castle? After sensing the status of the entire Infinity Castle, Ren understood the situation.
"Um... excuse me, but who are you?" Tanjiro hesitated for a moment before finally working up the courage to ask. Who was this gentleman who had appeared so suddenly? Why did he radiate the light of the sun?
Still, he probably wasn't a bad person, right? Tanjiro couldn't sense even a hint of malice from Ren Isana. Not to mention, Ren had just helped them avenge their master.
"My name is Ren Isana. I'm from another world. That fellow who was using spatial abilities accidentally pulled me over. You could say I'm a bit of a wild card!" It was all due to a spatial misalignment.
Coupled with the fact that the Dimensional Rift had happened to sync up with Ren's side, he had been dragged in. That Nakime person had truly pulled the right person for the wrong job!
"Another world..." The members of the Demon Slayer Corps were stunned by the news. Just as the shock was setting in, a massive rift tore open in the sky above the Infinity Castle, and countless chains came snaking out.
In an instant, a passage was forcibly pried open and stabilized in the air above. Seeing this, Ren Isana knew who had arrived. With a passage appearing inside the Dimensional Nexus University, it would have been weirder if Natsuki didn't react.
Thinking this, Ren Isana directly seized the permissions for this sub-space. In the next moment, everyone felt the world spin. When they recovered, they found themselves transferred right next to the passage.
"My teacher has probably discovered this place too. Next, I'll help you clean up those disgusting pests. Don't worry, not a single one will escape!" After saying that, Ren Isana raised his finger, condensing a [Mini Sun] that he then fired off.
When he first landed, his solar radiance had already wiped out many demons, but there were still plenty hiding in the shadows. This [Mini Sun] was meant to thoroughly purge every demon remaining in the Infinity Castle.
The moment Natsuki stepped into this world, she was greeted by a face full of blinding sunlight. Once the light faded, Natsuki looked around and fixed her gaze on Ren Isana. "How did you get pulled in?"
She had already been notified of Ren Isana's return and knew what he had done over on the other side. He had basically been kicked back home, but Natsuki didn't scold him. In fact, she secretly thought he had done a great job.
Furthermore, Ren's harvest this time must have been enormous, or else he wouldn't have been tossed back by that side. Since it wasn't a matter of universal outrage, they shouldn't have treated him that way normally.
"I don't know. I just got back to the dorm when I heard the sound of a biwa, and then I was pulled in. I saw them fighting, so I lent a hand and whipped up a [Sun] to one-shot that guy," Ren Isana said with an innocent shrug.
Nakime's luck was truly something else. She had triggered a spatial distortion and pulled off a 'single-pull miracle,' delivering a sun straight to the Demon King. It was absurd to the extreme.
Hearing Ren Isana's explanation, Natsuki was somewhat speechless. She looked at him and couldn't help but remark, "You've been encountering Dimensional Rifts more and more frequently lately."
Setting aside the one from the world of Zero, he had encountered a brand new Dimensional Rift while out on a date with Asuna. And now, the moment he returned to his dorm, he was pulled into yet another world.
Everything pointed to the fact that Ren Isana was a magnet for Dimensional Rifts. Moreover, the frequency of these rifts appearing lately was becoming alarmingly fast. *Is something happening to this world?*
Natsuki pondered this while her gaze fell upon Tanjiro and the others. The Demon Slayers were visibly nervous as they looked at Ren and the Dimensional Rift behind Natsuki.
People from another world? And they could enter their world so easily? Wasn't this a bit too much? However, looking at them, they didn't seem to harbor any ill intent.
"I am Natsuki Minamiya. Greetings," Natsuki introduced herself. The Demon Slayer Corps members looked at one another before stepping forward to introduce themselves as well.
After learning their names, Natsuki spoke slowly, "I've grasped the general situation. The state of affairs on our side is like this..."
Natsuki proceeded to explain the reasons behind the two worlds' connection. The group was shaken to their core upon learning the truth. A world that connected many different worlds?
The Demon King had been eliminated, but now that such a world had appeared, they didn't know if it was a blessing or a curse. At that moment, many of them felt a sense of apprehension.
"The [Sword Skills] of these people seem quite excellent, and their [Breathing Styles] have their merits, though they do overdraw one's potential. Every person here has health issues to some degree. If left untreated, they likely won't live past thirty," Ren Isana remarked while observing the Demon Slayers.
Some of these guys just shouted a [Breathing Style] and charged in, but in reality, it was just pure physical strength. Their movements could be described as incredibly crude. However, if these [Breathing Styles] were refined, they could potentially be used for high school students.
He had already gained a thorough understanding of the various [Breathing Styles] in this world through the [Information Reading] he had just learned from the Type-Moon world. He had to admit, this [Information Reading] ability was truly excellent.
Being able to read whatever information he wanted directly from the world—wasn't that basically [Omniscience]? He wondered if it would work in his own world. It might only be because this world was too weak to resist him.
Ren Isana found reading information in this world exceptionally easy. After all, this world didn't even have a World Will. Even if it did, it would be a very weak existence that couldn't possibly stop the current Ren Isana.
Natsuki nodded in agreement, acknowledging his observation. She looked at the group and said, "Soon, we will send representatives to discuss things with you in detail. I wonder if any of you can represent your side?"
The crowd looked at each other in silence. Their master was dead, and at the moment... there really wasn't anyone who could act as a representative. They exchanged glances until Shinobu Kocho, who hadn't perished in battle, stepped forward. "May we have some time to discuss this?"
Because of Ren Isana's sudden intervention, Shinobu Kocho hadn't died in the battle against Doma; instead, she had survived. Ren couldn't help but glance at her. Her body was severely overextended. If she didn't receive treatment, she would likely be dead within a month.
Natsuki had no problem with that. She nodded and said, "Very well. On the other side of that passage is our world. If you wish to cross over, you may do so directly. This sub-space is quite nice; I'll open a passage to the outside world for you. Once you've decided, just come find us there."

She wasn't in a hurry. These matters could be discussed slowly, and besides, she wasn't the one who would be doing the negotiating. Having said her piece, Natsuki opened a passage within the Infinity Castle leading to the outside world.
After completing this, Natsuki signaled to Ren Isana and turned to leave. The remaining matters were for them to decide. She wanted to head back and get a detailed account from Ren about what exactly he had done over there!
