"Hmm... There are many options, I'll just pick this one."
Seeing dozens of spells listed on the page, Ren chose randomly. Raising his right hand towards Gan'an, he spoke the name of the spell.
"Song of the Silver Fountain."
The next moment, a green light enveloped Gan'an.
"Ren-sama?!"
Before Gan'an could ask what the other party had done to him, he immediately felt the effect.
The wrinkles on his skin and his hollow cheeks disappeared in the blink of an eye, and his gray hair regained its black color.
Under the gaze of many people, Gan'an, who was originally a frail old man nearing the end of his life, now became a middle-aged man in his 40s full of vitality.
Activating the Divine Authority of the Book of Knowledge, Ren observed the results of his work and nodded in satisfaction.
'This rejuvenation magic is truly interesting. The effect is instant and comprehensive. With this, I don't need to worry about my women becoming unattractive old ladies in the future.'
'This Divine Authority of the Book of Knowledge is truly a treasure trove. There are countless spells with various effects. This is only a small fraction of its power.'
"Gan'an-san, how do you feel?"
"I... I feel like I've returned to my youth! This... this is amazing, Ren-sama! I don't know how I can repay your kindness!"
"No need to think about it. Just consider this a reward for your loyalty all this time."
"Unbelievable... I'm really young again."
Feeling the power of his youth flowing back into his veins, Gan'an breathed a sigh of relief. The decision to choose Ren over Godou felt increasingly correct.
What kind of power was this? A power that could turn back someone's biological clock.
Gan'an touched his firm face, touched his jet-black hair. This was more than just a gift, it was a second chance!
'Youth... it feels like such a long time ago. I doubted before, but now my decision is firm. Serving this person is the right path.'
A strange thought suddenly flashed through his mind.
'With this young body, should I try to have more children? My four children... Well, they're alright, but none of them have the outstanding potential to inherit the Shinomiya Family. Maybe with younger genes... this is an idea worth trying.'
"..."
Meanwhile, among the invited guests, silence enveloped the hall.
The miraculous scene before their eyes was too astonishing for words. They witnessed a frail old man transform into a middle-aged man in an instant.
The richer a person was, the greater their fear of death. This could be seen from the anti-aging and even immortality projects that tycoons funded.
"W-what... what just happened?"
"Such incredible power... If only I could regain my youth..."
"How could Gan'an get such good fortune? I want it too!"
Instantly, many elites began to yearn for the same position as the Shinomiya Family and the Momobami Family, serving an extraordinary figure like Ren.
Of course, among the people who witnessed the miracle that had just occurred, the one most strongly impacted visually was Yukino.
The girl, who had always stood firmly on the foundation of science and knowledge, always skeptical and even disgusted by anything supernatural, felt her worldview collapsing at this moment.
Her usually sharp and analytical eyes now stared blankly at the younger-looking Gan'an, her brain spinning hard trying to process something impossible.
"No... This is impossible."
"This must be some kind of trick. An optical illusion, or maybe accelerated genetic engineering? Yes, there must be a scientific explanation. That green light might contain some kind of enzyme or catalyst that accelerates cell regeneration. But this fast? That's unreasonable. There are limits to the laws of biology."
Yukino's voice was barely audible amidst the amazed murmurs of the other guests.
"No. I mustn't immediately believe in something absurd. This isn't magic. Magic isn't real. There must be a logical explanation for this. I just need time to think about it clearly."
Shaking her head slightly, Yukino tried to dispel the fog of confusion that was beginning to envelop her mind.
◆━⊰✧⊱━◆
'Pathetic woman. Even after the facts are shown right in front of her eyes, she still stubbornly denies it.'
Glancing at Yukino, who was doubting her own life, Ren felt a slight annoyance. Her stubborn attitude, even in the face of undeniable miracles, somehow made him dislike the girl even more.
What Ren didn't realize was that, besides Yukino, there was another girl who was also a student at Ohananomitsu High School. The reason he didn't notice her was because the other party deliberately hid so as not to be noticed by him.
"Truly amazing, Ren-sama. Is this the power of a Campione? It's truly beyond my expectations. Such power surpasses the limits of human understanding. Losing to Ren-sama doesn't seem like a shameful thing."
Kirari's eyes never left Ren's figure, her expression one of admiration and deep analysis. Now, her thin lips formed a small smile.
"My business is done. Prepare a car to take me home."
Seeing Ren turn around and walk towards the exit, Godou, who had been silent all this time, also moved.
"It's late, I want to go home too."
He felt awkward being in the midst of these elites. It was impossible for him to be alone at this banquet.
"Understood, two Kings. The car is ready." Gan'an replied respectfully.
He escorted them to the front yard of the magnificent house, where two luxurious black cars were parked waiting.
Unlike when they arrived together in one car, they now went home in separate vehicles. After all, the directions to their homes were different.
"Thank you for inviting me, Ren. See you."
"Goodbye, Godou."
After a brief farewell, Godou, along with Erica and Liliana, got into one car, while Ren, along with Masha and Alya, and the additional woman, Ririka, got into the other.
The two cars slowly glided away, cutting through the darkness of the Tokyo night.
◆━⊰✧⊱━◆
When Ren's car and his group arrived at the Rokuhara residence, the atmosphere inside the house felt quiet.
Itsuki had apparently already fallen asleep in his room, exhausted after a day of activities. Meanwhile, Hayasaka was in her room, enjoying a hydraulic press video on her laptop screen.
Masha and Alya understood Ren. They knew tonight Ren had "business" with the new girl. Without saying a word, the two Kujou sisters immediately returned to their rooms.
The two biological sisters shared one bedroom according to Ren's arrangement, an efficiency that made it easier for him to do *shimaidon* at any time without the hassle of moving between rooms.
The house had five bedrooms. Ren led Ririka towards one of the empty rooms that was yet unoccupied.
Ririka's steps felt stiff, and her hands trembled slightly. Her usually resolute face was now faintly flushed, her eyes occasionally glancing nervously at Ren. She could clearly guess what would happen next.
In the dimly lit room, illuminated only by the moonlight shining through the window, Ren stopped and turned to face Ririka.
He slowly lifted the girl's chin, forcing their eyes to meet. A thin smile, which might look threatening to some, was etched on his lips.
"Ririka, you know you belong to me now, right?"
"...Yes, Ren-sama. From now on, Momobami Ririka belongs entirely to you."
"Good answer. In that case, I will transform you from a girl into a woman tonight."
After saying those words, without waiting for further response, Ren pulled Ririka closer and kissed her.
