While Karin and the others were training their stamina, Takeru explained the basics of Nen to Emilia, Ram, and Rem, then forcibly opened their Aura Nodes. As their Nen emerged, Takeru looked at the three with surprise.

First, Emilia: the intensity and amount of her Nen were perhaps no less than Beatrice's at the beginning.

Perhaps because she was a half-elf. Elves have long lifespans, and Nen itself is essentially life energy. So, beings with longer lives have greater initial advantages when learning Nen.

Of course, besides Emilia, Ram and Rem were also no less impressive. As top-tier characters from the Re:Zero world and being Oni, Ram's Nen was no less than Emilia's, even stronger.

As for Rem, she was slightly weaker, but comparable to Takeru when he first awakened his Nen, indicating she was also genius-level...

"Now quickly use Ten! Imagine controlling it like your own mana." Looking at the three still surprised, Takeru said directly.

"Yes!" Hearing Takeru, they reacted and began controlling their Nen. Soon, they successfully used Ten.

Seeing all three easily achieve this, Takeru showed a smile. Because they could skillfully use magic from a young age and control mana, upon gaining the new ability Nen, they could also quickly master it...

After handling this, the next step was to familiarize them with Nen further. Takeru also explained the basic forms of Nen and helped them test their Hatsu. Though not necessarily developing towards Nen Abilities, understanding this ability more wouldn't hurt.

Subsequently, as time passed, afternoon arrived...

In the Service Club, Takeru's clone and team members gathered, discussing the Re:Zero World's situation.

"Takeru, do you know why we kept encountering very peculiar situations in that world? Like time rewinding, and not just once, causing us to only last less than a week there despite the mission being survival for a month." Ritsu said helplessly.

Initially, she thought they were under attack. But after testing, she found only she and those with her, Mio and Tsumugi, retained memories. Others didn't recall previous occurrences.

Also, the Reincarnation Space's countdown proved the world was continuously resetting...

"Actually, what caused all this was a person named Natsuki Subaru. That guy seems to have a death-return ability." Hearing Ritsu, Yukino directly said.

"Correct. And he seems to be a Transmigrator too, though not via the Reincarnation Space, nor from our world, but from a parallel world." Umaru also said.

They weren't stupid. After several resets, they investigated carefully. The most variable and active, Subaru, was discovered. Considering his special ability, even though he was a newbie, they didn't act rashly.

"Yes, Natsuki Subaru indeed has a death return ability, or rather Authority. But he's just an ordinary person. With some means, he can be handled easily and isn't something to fear. However, that world is actually far from simple. Leaving it safely wasn't a bad thing." Hearing them, Takeru said directly.

"Takeru, you also think that world isn't simple?" Hearing Takeru, Yukino and the others were stunned.

"Yes, correct. Did any of you meet Reinhard or join a Royal Selection candidate's faction?" Hearing her, Takeru directly asked.

"I met that man and also joined Crusch's faction, attending the royal council." Hearing Takeru's question, Yukino directly said.

It was through this she learned about Subaru.

"Is that so? Did you notice anything different about that man?" Hearing her, Takeru asked with interest.

"Using Observation Haki, I sensed his life aura was the strongest. He gave off a terrifying feeling. Though he showed no intent to act, he felt extremely dangerous." Hearing Takeru, Yukino said emotionally.

"Your perception wasn't wrong. That man is called the world's strongest Sword Saint, basically the strongest being in that world. If he wanted to destroy the world, it would purely be a matter of time." Hearing her, Takeru said directly.

"Can human power really reach that level?" Hearing Takeru, Ritsu and the others were dumbfounded. Only Umaru and Hachiman nodded with deep understanding.

They had seen with their own eyes that terrifying being. Hearing he was the world's strongest made it somewhat understandable. If many like him existed, that world would be truly fearsome.

Subsequently, they curiously asked about Witches. Takeru briefly shared some information but didn't elaborate much. For this mission world, everyone's ratings weren't high, with the highest being Yukino and Umaru with B+.

Others mostly got B to C ratings. However, Yukino and the others used that world to learn quite a bit of magic.

After sharing some gains, everyone adjourned. Regarding Mai, Takeru didn't bring it up since she said she'd come here later. It could wait until she formally applied.

After some discussion, everyone slowly left the club. Takeru took the waiting Ebina home.

Meanwhile, on Monster Island, after bringing everyone back to the hotel and home, Takeru waited at home for Miu to bring Hinata and the others.

…

"Master, we're here!" Takeru didn't wait long. Around four o'clock, Miu returned with Hinata, Hana, Noa, and the others.

"Welcome!" Hearing their calls and Hinata's sunny smile, Takeru couldn't help but smile.

"Ah, Ai, long time no see!" Seeing Hinatsuru, Hinata excitedly said. 𝙛𝒓𝓮𝙚𝔀𝒆𝒃𝓷𝒐𝓿𝙚𝓵.𝙘𝒐𝒎

"Hinata, we met just the day before yesterday, right?" Hearing her, Kanon gently reminded.

"Was that so?" Hearing Kanon, Hinata showed an adorable smile.

"Alright, Hinata, have you all been practicing well at home these days?" Seeing their interaction, Takeru found it amusing, but business first. So Takeru directly asked the two.

"Of course! Noa trains hard every day! Noa will definitely be the first to train Chakra and become the second senior disciple!" Hearing Takeru, Noa said excitedly.

"Ai won't lose! Ai trains with Master every day now! Ai will definitely be the first to extract Chakra!" Hearing Noa, Hinatsuru directly refuted.

"Eh? Training with Master every day?" Hearing Hinatsuru, Hinata and the others stared intently at Takeru.

"Haha, because Hinatsuru is handling transfer matters, she's temporarily staying at home and hasn't gone to school yet, so I take her for training." Looking at the five's gazes, Takeru explained helplessly.

"Eh? Too sneaky! Noa wants that too!"

"Hinata also wants to train with Master!"

Hearing Takeru, the five exclaimed excitedly. Karin and Miki nearby watched with amusement how Takeru would handle the five.

"No, no. Your most important task now is studying. Knowledge is also very important. For now, you just need to meditate properly every day at home. Remember, no slacking." Hearing them, Takeru directly refused.

Though Takeru also believed strength was more important, knowledge was equally important. Takeru didn't demand they learn too much knowledge or achieve great success in certain fields.

But one thing: they couldn't lack basic education. Also, their parents probably wouldn't agree to them dropping out for training.

Moreover, they were still young and just started training. For now, proper meditation to extract Chakra was the main goal.

"I understand." Hearing Takeru and seeing his determined look, the five could only nod.

"Then, Master, you called us here for something, right?" Hana quickly calmed down and looked at Takeru.

"Correct. As expected of Hana, so clever." Hearing her, Takeru smiled and patted her head, making her somewhat embarrassed.
