The Strongest Eriri in History

"What have you decided? Do you want to go somewhere else to hang out?" Kiyo Ishimaki took a sip of the milk tea she was holding and asked Eriri and Megumi Kato with a tentative tone.

Perhaps because Megumi Kato's presence was slightly enhanced by Eriri's strengthening of her body, she was not ignored by Kiyo Ishimaki and Azusa Satomi when they returned.

"No, let's end it here for today. Megumi-chan and I have something we need to take care of, but there will be plenty of chances for us to hang out in the future."

Since Eriri wanted to turn Megumi Kato into a superpowered individual today, she didn't feel like going out anymore and decisively rejected Kiyo Ishimaki's suggestion.

"Alright, then... Sawamura, Kato, we'll see you tomorrow at school." Seeing that Eriri had made her decision, Kiyo Ishimaki could only accept it with some regret.

"Yes, see you tomorrow, Ishimaki, Satomi."

...

After saying goodbye to Kiyo Ishimaki and Azusa Satomi, Eriri didn't let Aoi Kujo come pick her up. Instead, after obscuring the perception of the people around them, she grabbed Megumi Kato's hand and teleported directly back to her house. No one in the bustling street knew that two people had just vanished right before their eyes.

"Where is this?"

One moment Megumi was on the street, and the next, she found herself in a spacious and luxurious hall. The sudden change of scenery filled her with amazement. This kind of spatial movement was something only the legendary teleportation could achieve.

The cosmic energy within Eriri not only gave her an invincible body, limitless perception, and formidable strength, but it also allowed her to use various special abilities, teleportation being just one of them.

As long as she understood the principles of a certain ability, Eriri could naturally use it, making her powers nearly omnipotent.

"This is my home."

Saying that, Eriri walked over to a nearby sofa, tossed her backpack onto it, and curled up comfortably on the soft cushions.

Seeing Megumi Kato still standing there with a suddenly tense expression, Eriri quickly smiled and said, "Megumi-chan, don't be nervous. I just sensed that my mom isn't home, so it's just the two of us here. You can relax."

Looking at Eriri sprawled lazily on the sofa, Megumi Kato felt helpless, realizing she was the only one feeling uneasy, like a fool.

Confirming her relationship with Eriri, learning that Eriri was a superpowered individual, and now standing in Eriri's home about to become superpowered herself, Megumi's experiences today were richer than everything she'd gone through in her sixteen years combined. It felt so surreal she wondered if she was dreaming.

After becoming involved with Eriri, Megumi couldn't help but question if her actions were too rash and impulsive. But now, as she touched her chest and thought it over, she was sure her heart wouldn't deceive her.

In a lifetime, you rarely get to act on impulse. If it means not regretting her future life, why not fall head over heels in love once?

"So, what do we need to do to prepare?" Taking a deep breath, as if she had realized something and let go of her burdens, Megumi Kato walked lightly toward Eriri and spoke gently.

"There's nothing special to prepare. Come, sit with me for a while; I want to rest my head on your lap. We can talk about everything else later." Seeing Megumi's mood inexplicably lift, Eriri felt a bit puzzled but shrugged it off, patting the empty space beside her with a coquettish voice.

"Alright, alright." With a hint of indulgence in her tone, Megumi adjusted her school skirt and sat down beside Eriri.

Once Megumi was seated, Eriri eagerly snuggled against her, curling up and resting her head on Megumi's soft, rounded thighs, her face nestled against Megumi's soft, flat stomach.

Closing her eyes, inhaling Megumi's scent, Eriri could clearly feel a subtle change in Megumi, one that seemed to be for the better.

...

"Wah…"

With a cute yawn, Eriri slowly opened her eyes and felt the gentle hand stroking her head. Squinting, she snuggled further into Megumi's lap.

"How long did I sleep, Megumi-chan?" Eriri murmured, her face pressed against Megumi's belly.

"Not long. Did you sleep well?"

Megumi gently stroked Eriri's silky golden hair with great tenderness, as if handling a priceless treasure.

"Very well. Megumi-chan's lap is amazing." Lifting her head, Eriri smiled contentedly.

"Okay, it's getting late. It's time to get down to business. Come on, Megumi-chan, let's go to my room."

Glancing at the clock in the living room, Eriri reluctantly got up from Megumi's lap and motioned for her to follow as she headed to her room.

...

Leading Megumi Kato to her room on the villa's second floor, Eriri gestured for her to sit cross-legged on her luxurious white princess bed, then positioned herself similarly behind her.

Though not the first time she had altered someone's body, Eriri's previous modifications to the Sawamura couple had been gradual, nurturing their youth and extending their lives.

This time, however, she planned to complete Megumi's transformation in one go, intending to make her body adapt to Eriri's energy.

Without prior experience in this type of transformation, Eriri focused intently to ensure its success, aiming to evolve Megumi into a superpowered individual.

"Megumi-chan, are you ready?" With a serious expression, Eriri asked in a low voice.

"Yes, I'm ready." Taking a deep breath to calm her emotions, Megumi answered with determination. Not for anything else, but to always be with Eriri!

"Then... let's begin."

Gently pressing her palm against Megumi's back, Eriri channeled her vast cosmic energy, infusing it into Megumi's body as much as she could handle.

Megumi Kato's evolution had begun!
