Ren Isana had no idea that his communication with Natsuki was being eavesdropped on by those two. Time flowed differently between the two worlds; while it was night in this world, it was daytime for Ren Isana and the others back home.
Consequently, Ren Isana needed to adjust his sleep cycle. He immediately entered [Meditation] to wait for the arrival of the next day, while his classmates, scattered across the world, were progressively becoming busier.
The night passed without incident. When Ren Isana woke the next morning, he took some ingredients from his Spatial Ring and borrowed the kitchen of the kind family who owned the house to prepare breakfast.
By the time Ren Isana had everything ready, Sakura walked out of her room, eyes still blurry with sleep. She was momentarily stunned to see the breakfast he had made and hurried over to help.
"Go wash up first!" Ren Isana said, looking at the eager-to-help Sakura with a helpless smile. Children in this world were far too precocious. After speaking, he handed her a set of brand-new toiletries.
Looking at the items, Sakura hesitated for a moment before nodding. She took the things Ren Isana gave her and ducked into the bathroom to start brushing her teeth and washing her face. Meanwhile, the two Heroic Spirits also manifested in the dining room.
Their eyes instantly lit up at the sight of the delicacies Ren Isana had prepared. Food! Without any hesitation, the two sat down and began to enjoy the meal.
When Sakura emerged, Ren Isana immediately beckoned for her to come over and sit beside him.
Sakura was very obedient, silently making her way to his side and taking the seat next to him. After placing the prepared breakfast in front of her, Ren Isana spoke. "Sakura, in a little while, I'm going to send you to my teacher. She'll have everything arranged for you over there." He broke the news to her directly. Hearing this, Sakura asked nervously, "Big Brother, don't you want Sakura anymore?" Ren Isana sighed helplessly. "How could I not want you? We'll see each other again in the future. It's just that the Holy Grail War is about to start here, and I can't keep you with me at all times, which is why I'm sending you there."
Though a bit unhappy after hearing his explanation, Sakura still nodded and agreed. There was nothing else to be done. Since Big Brother Ren had things to do, this was the only way.
She didn't understand what the Holy Grail War was, but anything involving the word *war* had to be dangerous. However, Big Brother Ren was so powerful that he would surely be fine. She would forever remember that moment when he appeared before her like a ray of sunlight.
"Are you sending her away from this world?" Da Vinci-chan asked curiously. How exactly did he intend to send someone out? Wouldn't Alaya and Gaia try to stop him?
"Yes, I'm sending Sakura directly back to my world. Let's eat first; I'll get in touch with my teacher." As he spoke, Ren Isana began to communicate with Natsuki while finishing his breakfast.
On the other side, Natsuki was already awake. After receiving Ren Isana's message, she agreed to have the person teleported over in half an hour. She didn't hesitate and immediately set off toward the location of the dimensional passage.
After finalizing the arrangements, Ren Isana spoke to Sakura. "It's all set. I'll send you over in a bit. Don't worry, my teacher is very easy to talk to. Even though she's quite small and talks a bit stuck-up, she's actually a very good person."
While eating, Ren Isana continued to describe Natsuki's situation to Sakura. Listening to his descriptions, Sakura felt a weight lift from her heart, though she remained somewhat nervous.
Ren Isana's description allowed Sakura to slowly form a mental image of what kind of person Big Brother Ren's teacher was. *I hope she doesn't dislike me...* Sakura thought silently to herself.
Breakfast soon concluded, and Ren Isana began to take action. First, he applied a [Spatial Mark] to Sakura. Seeing the [Spatial Mark] he released, both Morgan and Da Vinci-chan watched with intense curiosity.
However, both were aware that now was not the time for research. Ren Isana needed to send the girl away; they could discuss it with him later. Since the Holy Grail War hadn't technically started yet, they had plenty of time for discussion.
With the [Spatial Mark] applied, Ren Isana used his connection with Natsuki as a coordinate and activated the skill. In an instant, Sakura's figure vanished, teleported away from this place.
Seeing her successfully teleported, Ren Isana breathed a sigh of relief. It seemed Alaya and Gaia hadn't blocked the transfer. *Thank goodness,* he thought, finally setting his mind at ease.
In reality, Alaya and Gaia could only watch with immense frustration as Ren Isana sent Sakura out. This was truly bullying; even if they wanted to find someone to complain to, there was no one left to listen.
A few minutes after sending Sakura off, Ren Isana received a communication from Natsuki. "The little one has arrived. This is quite extraordinary; she doesn't show a single symptom of discomfort."
This was a cross-world teleportation, yet the little girl was perfectly fine. Such physical constitution was exceptionally rare. Furthermore, Natsuki could sense the spatial attribute within her.
Ren Isana was right; this truly was a gifted little girl. This meant she finally had a true successor of her own. Since the girl was still young, Natsuki could teach her however she pleased.
"I'll leave her in your care. I'll see if I can trick her sister into coming over to you as well later," Ren Isana said, hearing the excitement in Natsuki's voice.
The moment those words left his mouth, Natsuki's head filled with question marks, while the eavesdropping Gaia and Alaya turned dark-faced. What did he mean by *trick her sister into coming over*?
"Kid, what are you doing in that world? Something is wrong, very wrong. Why do I feel like you're trying to become a human trafficker?" Natsuki frowned. She suspected that if this continued and Ren Isana went through a few more worlds, Nexus Island would end up being filled with children.
"I'm participating in a game called the Holy Grail War, and I've even summoned Heroic Spirits..." Ren Isana slowly began to explain the details of the Holy Grail War.
After listening to his explanation, a flash of surprise crossed Natsuki's eyes. He summoned Heroic Spirits? With that thought, she spoke up. "You should take this chance to learn well from the Heroic Spirits you summoned."
Those Heroic Spirits were figures from history, and each surely possessed a few unique specialties. If Ren Isana could learn them, it would be a massive gain. She naturally didn't want him to miss this opportunity.
"I'm learning, I'm learning. Let's leave it at that for now. One of these days, I'll go catch all the other Heroic Spirits and whip them until they hand over their secret techniques," Ren Isana replied casually before cutting off the call with Natsuki.
Natsuki was speechless at his words, but she let it go. Regardless, this wasn't her world, and with that kid's strength, he should be fine there.
If there were any problems, they could invade from their side immediately. With that thought, she looked at the somewhat timid Sakura and said, "Little one, my name is Natsuki Minamiya. From now on, call me Natsuki-ane. Understood?"
Another little girl to raise at home; it was truly something to celebrate. But this was good; it would give Kayo a companion. Natsuki reached out her hand to Sakura, deciding to take her back first.
Feeling Natsuki's goodwill, Sakura felt relieved. She reached out and took the hand, and under Natsuki's guidance, she walked out of the building to begin her return to Nexus Island.
Ren Isana, meanwhile, continued his exchanges with Morgan and the others. The Holy Grail War hadn't officially begun, so he had plenty of free time. Over the next few days, he constantly exchanged various types of knowledge with the two of them. He was like a greedy apprentice, frantically absorbing every scrap of knowledge Morgan and Da Vinci-chan taught him.
He accepted everything without exception. Simultaneously, he kept an eye on his classmates. By now, quite a few of them had gathered together, though they all had their own matters to attend to.
As such, they wouldn't be able to make it to Ren Isana's location for a while. Asuna had already met up with Yukino and Megumi Kato. This group had the least to do, so they simply decided to head over to find Ren Isana.
However, it would likely take a few days for them to arrive. Ren Isana didn't mind; by the time they got here, he might have already finished the Holy Grail War.
The disappearance of the Matou residence in Fuyuki City had become a popular topic of conversation. One afternoon, a plane landed at the Fuyuki City airport, and before long, two people emerged from the terminal.
The moment they touched down, Morgan suddenly smiled. She looked toward the direction of the airport and said, "My foolish sister has arrived. The Holy Grail War is about to begin!"
She sensed the presence of Artoria. This was perfect. This time, she would properly display her authority as the elder sister. A cold smirk played across Morgan's lips at the thought.
"The city's leylines have already begun to descend into chaos. If nothing unexpected happens, many people will be summoning their Heroic Spirits tonight," Da Vinci-chan added, speaking of the current state of affairs.
Ren Isana nodded in agreement. He felt it too. This banquet was about to begin. Touching his chin, he mused, "We know exactly what those Heroic Spirits are. Since we're currently in the dark, let's watch the circus first and then aim to clear it all in a single night!"
Emiya the Superhero managed to clear the Holy Grail War in a single night, and Ren Isana wasn't about to be outdone. What Emiya the Superhero could do, Ren Isana could do as well. Once the Heroic Spirits gathered, he would speedrun the whole thing that very night. Along the way, he'd capture Irisviel and Artoria, and then take the weapons he brought to have a sniping duel with Kiritsugu.
At the same time, Ren Isana wondered if he should go and cut off Goldie's arm? On second thought, he decided against it. If that guy got serious, things would get messy. A serious Goldie was terrifying!
It wasn't that he was afraid of losing—after all, he had two trump cards by his side—but it would be too much of a hassle. He would clear the war in a day, awaken the Holy Grail, research what was going on with the [Third Magic], and see if he could take a dip in that giant rice vat known as the [Root of Akasha]!
