After settling the Cursed Children into their new homes, Yuki led the Seitenshi and the others to select their own residences.
As some of the only adults in this sanctuary, they chose to live in the central district of the city. This would make it easier for the young girls to find them whenever they needed help.
During a discussion with Yuki, the Seitenshi brought up an important point. While the side effects of the Cursed Children's abilities had been erased by Yuki, the unique powers granted by the Gastrea virus remained. She felt it was essential for someone to guide them on how to use, control, and further develop these abilities.
Yuki agreed completely.
After all, living in this realm infused with his power would naturally cause their strength to grow over time. Learning to wield their abilities responsibly was a necessary step in their development.
While Yuki could teach them himself, he couldn't stay there permanently to do so.
He quickly devised a solution. He would teach them whenever he visited, but for their daily education, he would enlist the Celestials.
As conceptual beings, the Celestials possessed knowledge far beyond that of most advanced civilizations. They would be perfect not only for instructing the girls in controlling their powers but also for teaching them about cosmic sciences and other subjects.
The Seitenshi readily agreed with this plan.
Shishioh Miju then volunteered to serve as a teacher herself, offering to instruct in subjects other than science—such as strategy, history, and diplomacy.
Upon hearing that the cosmic Celestials would be teaching advanced science, Dr. Shidou Arika couldn't contain her excitement. She immediately signed up as a student.
Of course, it wasn't just Arika; the Holy Maiden and the others were also deeply curious about the knowledge the Celestials would impart.
Naturally, they weren't going to miss this opportunity.
Once the decision was made, Yuki fashioned a brand-new, female Celestial into existence. Under his direction, she would be stationed in this sanctuary as their resident teacher.
The reason he didn't assign an existing Celestial was simple: the others already had their duties in neighboring universes. Creating a new one was the most straightforward solution. Moreover, the conceptual nature of the other Celestials didn't quite fit the role of an educator. This newly formed being, embodying the very concept of knowledge, was perfectly suited for teaching.
With these matters settled, Yuki gathered all the girls for a massive celebration. He spent the entire day with them, playing and enjoying the festivities. When night fell, he decided to stay over.
That night...
Yuki not only revisited the tenderness of Seitenshi and Tendou Kisara but also experienced the fresh, passion of Shishioh Miju and Dr. Shidou Arika.
It wasn't until the next day that he finally bid farewell to Seitenshi and the others, returning to the world of Date A Live.
Back at school, it was already lunchtime. Just as Yuki was about to head back to his classroom, a figure suddenly rounded the corner and bumped right into him.
"Whoa, careful there."
Reacting instantly, Yuki reached out and caught the person. His hands found a waist as slender and supple as a willow branch.
Looking down, he saw the distinctive cherry-blossom pink hair, the formal dark jacket, and the maroon pencil skirt. It could only be one person: Mafuyu Kirisu.
"You alright, Kirisu-sensei?" Yuki smiled, subtly giving her slender waist a slight squeeze.
"I'm fine, it was my fault—" Kirisu began, but then she froze. As she looked up and realized it was Yuki she had collided with, her expression went completely blank.
Confronted with his close-up smile, Mafuyu found herself unconsciously drawn in by his overwhelming charm. The potent, masculine aura he radiated made her heart race uncontrollably. Her gaze grew gradually dazed and distant.
She remained in that stunned state for a full two minutes, only snapping back to reality when she heard Yuki's voice asking if she was okay.
"I... I'm fine now. Thank you, Yuki-kun." A faint blush colored her cheeks as she averted her eyes, unable to meet his gaze. "So... could you please let me go?"
Yuki gave a light chuckle and nodded. "Sure."
He released her.
As the warmth of his large hands left her, a faint, inexplicable sense of loss flickered within Mafuyu's heart. But it was quickly overshadowed by her flustered reaction to his mere presence.
She quickly smoothed out her clothes, straightening the wrinkles, and lifted her head, her expression cooling back into its usual professional composure.
"You were absent for two hours and missed two classes. What is the reason for this, Yuki? I expect an explanation."
Mafuyu Kirisu had fully shifted into strict teacher mode, interrogating him about his unexplained absence.
"But I already told the teacher in class. I wasn't feeling well," Yuki replied, his face a mask of feigned surprise before he shrugged innocently.
"Not feeling well? I checked the nurse's office, and you weren't there," she countered, her brow furrowing. "So, are you going to tell me the real reason, or not?"
Her tone made it clear she saw right through his excuse.
Yuki let out a quiet sigh of resignation.
"If there's something difficult going on, you can tell me," Kirisu continued, her voice softening slightly. "As your teacher, it's my job to help you."
"It's my responsibility as your homeroom teacher."
She launched into a well-intentioned lecture, hoping he would confide in her if he had any problems.
"Hold on, hold on, Kirisu-sensei. I really don't have any issues!" Yuki insisted, his tone pleading.
"If I did have a problem, I'd come to you!"
"Look, it's lunchtime now. You haven't eaten yet, right? You should go get something to eat!"
"I'll be going now!"
With that, he made a quick escape, not giving her a chance to react.
By the time Mafuyu processed his words and tried to follow, he had already vanished around a corner.
A flicker of frustration crossed her features.
"That boy... he's so troublesome!" she muttered under her breath, her lips forming a slight, uncharacteristic pout that made her look like a petulant girl.
"But don't think this is over! I'm going to have to contact your parents about this and get to the bottom of it!"
Having declared this, she turned on her heel and strode purposefully away.
After his getaway, Yuki soon found himself in a quiet corner of the school building.
He checked the time; most of the lunch period was already over, so he decided against going to the cafeteria. Instead, he began wandering aimlessly around the school grounds.
He did a quick mental calculation. Ellen and the others wouldn't be back for a few more days. He could plan a little surprise for their return.
During the thirty years they had waited for him, Ellen and her team hadn't been idle. They had founded a conglomerate named "Infinity," a new, comprehensive company providing military technology and advanced tech to nations worldwide, effectively becoming the successor to DEM.
Leveraging the sisters' magic and Tiayu's scientific expertise, the company's products were technologically superior to anything else on the globe.
Especially after the previous alien invasion, nations were desperate to enhance their military capabilities. Infinity's products were, naturally, in extremely high demand.
This successfully propelled the company to become one of the most valuable and leading enterprises globally.
A company with such high value and advanced technology inevitably attracted covetous eyes from many countries. Some had tried underhanded tactics.
However, after one particular incident where Ellen and her team personally eliminated a significant portion of the leadership in a country that had moved against them, every other nation promptly abandoned any such ideas.
They could only cooperate with Infinity, no longer daring to entertain any sinister schemes.
As for Ellen and the others' current whereabouts, they weren't even in the Milky Way. They were in a galaxy trillions of light-years away, observing an interstellar war between alien civilizations and testing some new weapons in the process.
