In the living room of the Sawamura family villa, Arifureta and Megumi Kato were chatting together, looking very harmonious. Meanwhile, Shea and Reina were sitting on the sofa, engrossed in their newly bought phones.
At that moment, a mysterious portal emitting white light suddenly appeared in the center of the living room, drawing the attention of everyone present.
Including Megumi Kato, none of them were strangers to this world portal. Arifureta, Shea, and Reina had personally experienced it before, and as for Megumi Kato, she had previously witnessed Eriri opening such a portal to leave this world.
The four girls' faces lit up with joyful smiles as they stood up and walked towards the portal, ready to welcome Eriri's return.
However, before they could take a step forward, Eriri stepped out of the portal first. She retracted the world power sustaining the portal, and it closed instantly behind her.
"I'm back!" Eriri said with a smile, greeting them as she noticed Arifureta and the others moving towards her.
She then quickly moved in front of them, picked up Reina, and sat down on the central sofa.
"Welcome back, Eriri. Did you finish everything in the other world?" Megumi Kato, sitting next to Eriri, asked, her eyes filled with curiosity.
After Eriri had gone to the other world, she had heard from Arifureta about what Eriri was going to do, and she was very interested in the Full Dive game.
"Yes, everything is ready. Now we just need to wrap things up," Eriri said, stroking Reina's fluffy tail, a content smile on her face. Then she glanced around the villa. "Is Aoi not home?"
"Aoi went out to buy ingredients for dinner. She should be back soon," Arifureta, sitting on Eriri's other side, replied softly.
Eriri nodded at this. It was already past four in the afternoon, and with more people at home, preparing dinner took longer. By the time Aoi Kujo finished cooking, it would be around six, just in time for dinner.
She then started telling Arifureta and the others about what had happened in the Sword Art Online world during the past two hours.
Amid the cheerful discussions of the group, time flew by quickly, and soon Aoi Kujo and Mrs. Sayuri also returned home.
Eriri introduced Megumi Kato to Mrs. Sayuri. Mrs. Sayuri was very warm towards her daughter's first girlfriend.
Initially, Megumi Kato was very nervous when facing Mrs. Sayuri, but after this short time together, the future relationship between mother-in-law and daughter-in-law became very harmonious.
Seeing Mrs. Sayuri chatting enthusiastically with Arifureta, Megumi Kato, and Shea, Eriri slowly said, "Mom, could you help me prepare a bigger villa? We're planning to move in."
"What? Is Eriri planning to abandon her mom?" Mrs. Sayuri immediately put on a sad face, as if she had been abandoned, even covering her face and pretending to sob a few times.
"Alright, stop pretending. Your acting isn't convincing at all," Eriri said with a look of disdain.
"Really? Wait, let me try again," Mrs. Sayuri moved her hands away, her face no longer showing any sadness.
Watching the mother-daughter pair's antics, Arifureta and the others couldn't help but smile. At first, they were really startled by Mrs. Sayuri's expression and were ready to comfort her, but they didn't expect it to turn out like this.
"Okay, you can play later; let's talk business now." Eriri stopped Mrs. Sayuri, who was about to start acting again, her face showing a helpless expression. This kind of thing had happened countless times over the past ten-plus years.
"Eriri, why do you need a villa? The rooms here are enough for Arifureta and the others," Mrs. Sayuri asked, also stopping her antics. Although she loved goofing around with Eriri, she was serious when it came to important matters.
"In the future, some friends from other worlds will come to stay here, and the rooms here won't be enough."
"I see... No problem, leave it to me. I'll carefully prepare a villa for you. And by the way, don't forget to leave me a room, okay?" Mrs. Sayuri nodded, agreeing to Eriri's request, then added with a change in tone, "Of course, even if you don't, I can just sleep with you when I come over."
Eriri didn't object to Mrs. Sayuri's words. Naturally, she wouldn't refuse her mother's request. She had long planned to prepare a bigger house so that when the chat group members came over to play, there would be enough rooms for them to stay.
Eriri also asked Mrs. Sayuri to prepare a few good cars for future use.
...
After dinner, it was already past seven o'clock. Megumi Kato, after reluctantly saying goodbye to everyone, left the Sawamura residence.
Once Aoi Kujo finished clearing the table, Eriri brought her into the bedroom, accompanied by Arifureta and the other two.
Eriri planned to turn Aoi Kujo into a superhuman while also enhancing Arifureta and the others' powers.
Looking at Aoi Kujo, who was wearing a maid outfit and whose eyes were filled with anticipation, Eriri didn't keep her in suspense and said directly, "Aoi, do you remember the surprise gift I mentioned to you this morning?"
"I remember." Aoi Kujo nodded, her anticipation growing stronger. She was very curious about what the surprise gift Eriri had mentioned could be, especially since she had been brought to the bedroom for it.
"Could it be..." The thought made Aoi Kujo's breathing quicken a little, but when she saw Arifureta and the others standing nearby, she immediately dismissed the impure thoughts.
"I'm going to help you become a superhuman."
Hearing what Eriri said, Aoi Kujo's breathing quickened again, and her eyes shone with excitement. Although it wasn't the gift she had imagined, which left her a little disappointed, the prospect of becoming a superhuman brought her immense joy.
Although spiritual energy had been revived in the world, she wasn't sure she would become a superhuman. Now, with Eriri's help, all her previous worries vanished.
"Thank you, Miss."
Then Eriri had Aoi Kujo sit cross-legged on the bed, and she sat behind her, placing her hand on Aoi Kujo's back. Just as she had helped Megumi Kato evolve, Eriri skillfully transformed Aoi Kujo's body.
After some time, Eriri slowly retracted her hand. Now, it was just a matter of Aoi Kujo fully adapting to the cosmic energy, and her evolution would be complete.
Next, she had Arifureta, Shea, and Reina sit in a row on the bed. Fortunately, Eriri's princess bed was big enough to comfortably fit all four of them.
Using the same process, Eriri sent Arifureta and the others down the path of evolution as well.
Since Arifureta and Shea were already superhumans, Eriri's infusion of cosmic energy to enhance their magic and physical attributes would allow their powers to grow rapidly. They could still absorb external magic to continue their training without being limited by cosmic energy.
However, Aoi Kujo and Reina were different. Aoi Kujo was just an ordinary person, while Reina was a non-magical beastman.
After Eriri transformed them into superhumans, they were like Megumi Kato, unable to absorb cosmic energy on their own. So once the cosmic energy in their bodies was depleted, they would need Eriri to replenish it.
After finishing everything, Eriri got off the bed and looked at the three beautiful girls and the little loli sitting with their eyes closed, feeling their increasing energy. A satisfied smile appeared on Eriri's face.
Time passed quickly, and in the blink of an eye, half an hour had gone by, and Arifureta and the others' evolution was nearing completion.
Cosmic energy lived up to its name, with incredible beautifying effects. Compared to before, the four of them had undergone significant changes.
Arifureta and Shea were already stunningly beautiful, so it was nearly impossible to reach Eriri's level of beauty. Eriri's divine beauty was said to be unparalleled across all worlds, hence her title as the most beautiful girl in the universe.
After the evolution, Arifureta and Shea's beauty only increased slightly. The most noticeable change was that their body proportions became even more perfect, and their skin glowed with a crystalline sheen, as if it were emitting a soft light.
Looking at the curvaceous, stunning blonde beauty before her, who looked about twenty years old, Eriri's eyes gleamed with excitement. This was Arifureta.
Due to her auto-regeneration ability, Arifureta's body had been stuck in a thirteen-year-old form for over three hundred years. But after the cosmic energy transformation, the flaw in her auto-regeneration was fixed, and her body returned to its peak state.
Because of her rapid growth, the clothes that had previously been loose-fitting were now tightly clinging to Arifureta's perfect figure. Her breasts stretched the fabric around her chest, making it look like it would burst at any moment.
The dress that once reached her thighs was now pulled up to her waist, revealing two long, pale, flawless legs and a pair of tight white lace panties that were fully exposed to the air. If it weren't for the quality and elasticity of the fabric, the panties might have torn by now.
Looking at the alluring sight before her, Eriri couldn't help but swallow hard, feeling an overwhelming desire. She resisted the urge to reach out and touch that perfect body and instead picked up a blanket to cover Arifureta's exposed legs.
Moving on to Aoi Kujo and Reina, Reina, who was already extremely cute, had now become even more like a delicate porcelain doll. Her white fur had become dazzlingly bright, each strand looking like a work of art.
The most significant change in Reina's body was her tail. Above her hips, nine fluffy fox tails had appeared, all gathered together, making them even larger than her petite frame. Each tail was covered in glowing white fur, making them look incredibly beautiful.
"Nine tails? Is this some kind of ancestral trait? I wonder if the fox-beast tribe's ancestors were nine-tailed foxes..." Eriri muttered to herself, unable to contain her joy.
As for Aoi Kujo, though her transformation was also impressive, it paled in comparison to the changes seen in Arifureta and Reina.
Aoi Kujo, who had originally been a rare beauty, now had her appearance enhanced several levels. While she had always been attractive, she had lagged behind the likes of Megumi Kato and others. Now, after her evolution, her beauty was on par with theirs.
Her skin, compared to before, was like night and day. This was the difference between mortals and superhumans. No matter how well a mortal's skin is maintained, it will always have some imperfections due to the passage of time. Now, Aoi Kujo's skin was as white and delicate as snow, without a single flaw.
Her appearance also made her look several years younger, around seventeen or eighteen years old. Her figure had also been slightly adjusted by the cosmic energy, eliminating any imperfections that had previously existed.
Looking at the drastically transformed appearances of the four, Eriri could only think—Cosmic energy is amazing!
Time passed, and after a few more minutes, the four girls gradually opened their eyes, each exhaling softly. They then began to feel the changes in their bodies, and smiles of excitement spread across their faces.
"Arifureta, Reina, you..." After sensing the changes in her own body, Shea turned her head to look at Arifureta and Reina beside her, her mouth slightly open in shock.
By this point, Arifureta and Reina had also noticed the changes in their bodies, and like Shea, they were equally surprised.
"Onee-chan, Onee-chan, I have nine tails! Come and touch them, they're so fun!" Reina excitedly waved at Eriri, then began to control her nine tails, posing them in different positions and playing with them joyfully.
"Eriri, what's going on? How did I suddenly grow up?" Arifureta, wrapping the blanket around her waist, stepped down from the bed. She began to touch her body with her hands, her eyes shining with joy, clearly satisfied with the changes in her figure.
"Miss, I feel like my body is filled with strength. This is incredible!" Aoi Kujo said, equally delighted. Although she was still unaware of what specific superhuman powers she possessed, she could tell that her physical strength had increased exponentially compared to before.
