Suddenly hearing Natsuki Minamiya say this, Ren Isana and Asuna were both stunned. *Does such a world really exist? For real?* If that were the case, Ren Isana was definitely interested.
"Tell me more. What kind of world is it?" Ren Isana asked urgently. A world mentioned like this by Natsuki Minamiya couldn't be ordinary.
Natsuki Minamiya nodded, but she didn't agree immediately. Instead, she said, "Go back first. I'll give you the documents later. I can't explain it clearly in a short time. You can decide whether to go or not once you see them."
After speaking, Natsuki paused. She looked up at Ren Isana and said, "You're almost at Tier 6, aren't you? If you go to that world, you'd better break through first. Furthermore, I don't intend to let anyone without Tier 5 strength go this time. Tell me when you're about to break through; that god you're holding onto will be of use."
Natsuki's words gave Ren Isana pause. He looked up at her and nodded in agreement. "I understand. Right now, I'm only about 10% away. I'll put in some hard training next."
*Not allowed to go without Tier 5 strength?* If that was the case, that world must be quite terrifying. His own breakthrough definitely had to be prioritized on the schedule.
Asuna's heart also tightened at the side, because her strength hadn't reached Tier 5 either. Up to now, her Excelia bar was only at 70%.
It would be depressing if she couldn't go when the time came for the new world. Asuna made up her mind and set her resolve.
She couldn't indulge in distractions anymore. Ren Isana was just too exhausting. She planned to rest for a while and focus entirely on improving her strength!
After finishing his talk with Natsuki, Ren Isana looked toward Emilia, Rem, and the others. "We'll head back to the school first. You follow Natsuki and get settled in. I'll come find you soon."
The girls nodded, having no objections. They had heard the conversation between Ren Isana and Natsuki. Since Ren Isana and the others had things to handle, they didn't want to get in the way.
"Beatrice, are you going with Puck and the others?" Ren Isana asked, turning his gaze to her. Although they had signed a contract, he would never restrict her freedom.
"Hmph, Betty is not such a clingy spirit. If I want to see Big Brother in the future, I will just go find you. Since you are Betty's contractor now, Betty will naturally follow you!" After saying that, she transformed into a mote of light and vanished.
Ren Isana could feel that she had returned to her library. Natsuki watched the entire scene, her eyes flashing with a hint of surprise as her gaze fell upon Ren Isana's heart.
In the instant Betty entered, Natsuki had captured that spatial fluctuation. *This kid... did he actually pull off what Kumo told me? He opened up a space inside his own heart?*
Thinking of this, Natsuki could no longer sit still. she quickly asked, "Did you succeed in what you mentioned to that girl Kumo? Opening a second Magic Power source!"
When Ren Isana noticed Natsuki's gaze, he realized he could no longer hide the thing in his heart. Hearing her ask directly, he nodded.
Since she was only asking about that, it was fine. Ren Isana simply admitted it; it was complete, and he even had a methodology for it.
"Fine, I understand. Go back for now!" Once Natsuki confirmed it, she didn't say much more. She simply waved her hand, signaling for Ren Isana and Asuna to return to school.
She could ask Ren Isana about those details privately later. For now, she still had to escort these spirits to the Elven Forest.
Ren Isana nodded and waved goodbye to Emilia and the others. He then took Asuna's hand and used [Spatial Teleportation] to leave the hotel, reappearing instantly at the school gates.
The two of them walked toward the entrance. After swiping their student ID cards, they easily entered the campus. Since it was evening, there were still many students coming and going.
Seeing Ren Isana use [Spatial Magic] to bring someone along made many people look on in surprise. *Did another student learn [Spatial Magic]? That's incredible.*
After entering the school, Ren Isana pulled Asuna toward the dormitories. The fact that they were dating wasn't really a secret in their class anymore.
Thus, Ren Isana didn't fear being seen openly holding Asuna's hand. On the way back, Asuna couldn't help but say, "I need to seriously enhance my strength now. Otherwise, I'm afraid I won't be qualified for the next mission."
Ren Isana nodded in support. "It's definitely time for that. Practice hard. The others in class are even further behind than you, so you don't need to worry too much. If even you can't go, then no one else should even dream of it."
"And in that case, you'll be the only one executing the mission alone," Asuna rolled her eyes. She only hoped it wouldn't come to that, as it would be quite frustrating.
"I don't really mind, but what I'm curious about is why Natsuki wants me to go once I break through to Tier 6," Ren Isana had been pondering this question.
Director Ken had told him to keep Apollo's corpse, saying it would be useful in the future, so Ren Isana hadn't disposed of it. Now that Natsuki had mentioned it, it seemed the time to use it had come?
It was very intriguing. To understand this point, becoming stronger was undoubtedly Ren Isana's primary goal.
As they chatted while walking toward the dorms, a voice filled with resentment suddenly rang out: "Isn't this our dear Class Rep who went off on a date and ended up in another world?"
Hearing this voice, Ren Isana's lips twitched slightly. The two of them turned to see several female classmates, each holding a cup of milk tea—Sora, Shikimori, Yukari, and Kumo.
"That's right, it's me. What of it? You got a problem?" Ren Isana glanced at Sora. *What's with this jilted-woman tone? Did some scumbag dump her?*
"Damn it!! I totally have a problem! Class Rep, you guys are too much, running off to another world without taking us!!" Sora ran up as she spoke, pulling a cup of milk tea from her Spatial Ring for Asuna, then another for Ren Isana.
Seeing this girl handing out milk tea again, Ren Isana didn't stand on ceremony. He took it, poked the straw in, and started drinking. As they walked, he said, "If you want to blame someone, blame Natsuki. She's the one who threw us over there."
Ren Isana washed his hands of the responsibility. If they wanted to complain, they should go to Natsuki. They couldn't go wrong blaming her.
"Forget it, forget it. Class Rep, why did you come back so fast this time? Is there nothing good in that world?" Sora's fussing was just a joke.
After all, they knew the situation. Ren Isana just happened to be on the scene; if they had been there, they probably would have been tossed across too.
Compared to that, she was more curious about the other world. Why was he back after only a few days? The speed was almost too fast.
"Because I've already figured out the situation there. The harvest this time was quite large. I brought back some spirits and several students with excellent potential. Especially... one girl who possesses infinite Magic Power."
When Ren Isana mentioned infinite Magic Power, Kumo's eyes lit up with a terrifying intensity. She said, "For real? Infinite Magic Power?"
She could hardly believe what she was hearing. That was the dream mana capacity she had always longed for; just thinking about it made her drool.
"Close to infinite. It's basically the same thing, because she can draw Magic Power from the atmosphere at all times for her own use," Ren Isana explained some of Emilia's circumstances.
That was an innate talent; one couldn't learn it even if they wanted to. There was no harm in saying it, and it probably couldn't be kept secret anyway.
After listening to Ren Isana's explanation, Kumo's eyes widened with longing. At the same time, she remembered something and hurriedly spoke to Ren Isana. "Class Rep, I've already consulted Natsuki. She said that method is feasible, just extremely difficult."
Kumo began to explain the things she had discussed with Natsuki. To complete the 'second blue bar' Ren Isana had mentioned before, she had put in painstaking effort during this period.
After listening to Kumo, Ren Isana nodded. "Actually, I already completed it during this trip to the other world. By borrowing some magic from there, I've already opened a space in my heart to store Magic Power."
Ren Isana was also amazed after hearing Kumo's explanation. This classmate was truly ridiculous; she had already refined so many things. As expected, Kumo had the best magic talent in class besides himself.
"Really? How much Magic Power can it store?" Kumo became even more excited when she heard Ren Isana had succeeded. Regardless, she was determined to learn that magic.
"It depends on how large a space you can open. Theoretically, ten times your own Magic Power is the best result. Any more and it will go out of control, unless your strength grows significantly," Ren Isana gave a figure after a mental estimation.
Ten times one's own Magic Power. He wouldn't suggest more, as that would be playing with fire. As for the specifics, it depended on the individual; some might not even be able to get started.
"Ten times one's own Magic Power!! That much!!" Kumo's excitement peaked. Her Magic Power was already high, the highest in class after Ren Isana.
Of course, if she activated her unlimited firepower mode, she would be a weakling because she lacked endurance. But without it, her total Magic Power was quite formidable.
"Yes, I'll organize the details later and send them to you. As for the others... I don't suggest everyone try it. Especially those with poor magic aptitude; they wouldn't even be qualified to learn this."
Ren Isana didn't bother naming the male classmates one by one. Many wouldn't even qualify to study this magic because the requirements were too high and it was incredibly dangerous. One slip-up and you'd blow your own heart out.
Kumo nodded, naturally understanding the danger. This was like performing surgery on one's own heart.
If people couldn't even meet the basic prerequisites, how could they handle the subsequent learning? Therefore, it was better to keep some things private.
"In that case, hasn't the Class Rep's strength increased again?" Sora and the others had been listening to the conversation between Ren Isana and Kumo, and she was green with envy.
Coming back from a trip to another world with a perfected second Magic Power source... Ren Isana was already a V8 engine, and now he'd added another motor. This was getting ridiculous.
"I'm just a little bit away from breaking through. Oh, right, there's something I should tell you all. Natsuki mentioned the requirements for the next world we're going to explore. You need to be at Tier 5. You'd better figure something out."
Ren Isana suddenly dropped this unpleasant piece of news.
"Huh?" Sora was stunned. Tier 5 strength just to participate in the next world?
Wasn't this just making things impossible for her? Her current strength was only halfway through Tier 4; Tier 5 was still a long way off!
At that moment, Sora panicked. she hurriedly said, "Go, go, go! Back to training! We can't keep going like this. We have to break through immediately, or we won't have a chance to join the next exploration!!"
After saying that, she dragged the others toward the dorms. Ren Isana didn't know whether to laugh or cry. Once they were far away, Asuna said jokingly, "Is it really okay to pressure them like that?"
The students in the class had unprecedented enthusiasm for exploring new worlds. Now that Ren Isana had said this, the pressure had spiked. To avoid being left behind, they could only grind like crazy.
"It's fine. It's better if everyone grinds a bit. Let's go, we should head back too. Do you want to come down to my dorm tonight?" Ren Isana tightened his grip on Asuna's small hand.
The sudden turn of subject made Asuna's face flush. She glared at Ren Isana and said dismissively, "Don't even think about it! You bad guy, don't think of those things once we're back at the dorms."
With that, Asuna broke free from Ren Isana's hand and used a [Shunpo・Flash Step] to vanish on the spot, not intending to continue the conversation for fear she wouldn't be able to refuse.
Looking at the fleeing Asuna, Ren Isana chuckled but said nothing more. A [Magic Circle] appeared beneath his feet, and he also vanished.
When he reappeared, Ren Isana was back in his dorm. Turning on the light, he went to collect the clothes he had left out to dry and then began to wash up.
When the people nearby noticed the lights in Ren Isana's dorm, they realized he was back. Everyone pulled out their phones and began asking questions in the group chat.
However, no one was getting a reply for now, as Ren Isana had already started showering, and his phone was still in his Spatial Ring, so he couldn't receive any messages at all.
After showering and drying his hair, Ren Isana took out his phone and sat at his computer, preparing to organize the data for Natsuki.
Seeing the dense wall of messages in the group, he felt a bit speechless. With a spark of electricity at his fingertips, he didn't bother reading them one by one, instead using the hacker skills he'd learned from Asagi Aiba to read through them instantly.
After understanding the recent events, Ren Isana finally popped into the group chat. Simultaneously, his computer opened automatically, a document appeared, and the cursor began typing on its own.
Ren Isana entered various pieces of information about the other world into the file. Multitasking, he replied to the students' messages while completing the work he needed to do.
In addition to information about that world, Ren Isana also included some theoretical knowledge of [Spatial Magic]. This was specifically for Natsuki; he believed she would understand it.
As for time-related magic, Ren Isana didn't plan to release that. It was better for him to hold onto such things, as he feared others wouldn't be able to handle them.
While chatting and processing the data, Ren Isana gave it a final review. Seeing no major issues, he sent the file directly to Natsuki.
He placed particular emphasis on the fact that [Divine Protection] obtained in that world could not be used back in their world, though the loss of the [Divine Protection] would still grant new attributes.
It was a guaranteed profit—provided one could obtain a [Divine Protection] in that world. Ren Isana wrote all of this down clearly.
Once satisfied, he saved the file and began organizing the knowledge regarding the second Magic Power source. He'd let Kumo handle that herself, though he hoped she wouldn't accidentally erase herself in the process.
He also had to report this to Natsuki, otherwise, the sight of a student accidentally blowing themselves up would be far too much 'fun.'
Once the files were ready, Ren Isana sent them out. Natsuki quickly replied with a 'received' and nothing else; she was currently working overtime and had no time to look through them.
Ren Isana couldn't be bothered to care once the items were sent. He lay down on his bed, activated his [Perception Magic], and looked at Asuna upstairs. With a slight smile, he took out his phone to chat with everyone.
Ren Isana also mentioned the requirement of Tier 5 for the new world. Unsurprisingly, the students felt like the sky was falling upon receiving this news.
One after another, they began asking when they would be setting off. Everyone was clearly getting anxious, as no one wanted to miss out.
After chatting with his classmates for over an hour, Ren Isana finally put down his phone to rest. When he picked up his phone the next morning, there was an additional file regarding the new world—sent by Natsuki in the middle of the night!
