The Strongest Eriri in History

"Hmph, you don't believe me? Then I'll let you feel it for yourself."

Eriri gently pressed her palm against Megumi Kato's soft abdomen, channeling the energy from within her into Megumi's body, bit by bit.

As the gentle energy slowly entered her body through her abdomen, Megumi Kato immediately felt entirely relaxed and comfortable, as if she were floating on a cloud.

Megumi distinctly felt a significant boost in her vitality, and the slight fullness she had felt after eating disappeared completely. She even felt she could return to the cake shop and enjoy more cake.

There's no denying that this cosmic energy is truly convenient.

"So, do you believe me now?" Eriri said with a proud tilt of her head as she stopped transferring the energy.

Feeling the changes in her body, Megumi Kato couldn't help but believe in the reality of superpowers, which shattered the worldview she had built over sixteen years.

"If superpowers are real, does that mean there are other superpowered people in the world? Could the legendary monsters and demons be part of our daily lives too? If so, wouldn't ordinary people be in great danger? Could all those unsolved murder cases in history be..."

Confronted with an incomprehensible field, Megumi Kato uncharacteristically bombarded Eriri with a flurry of questions.

"Stop, stop, stop, stop... Megumi-chan, calm down first. What you're worrying about doesn't exist. As far as I can sense, there's absolutely no one else in this world with extraordinary powers like mine, so you can rest easy. Besides, even if something strange does happen in the future, nothing will be out of my control."

Eriri was extremely confident in her current strength, believing that nothing in this world could challenge her.

"Eriri... why did you suddenly decide to tell me about this?" After a moment, Megumi tilted her head, a hint of confusion in her eyes. From what she knew from TV shows and anime, people with special powers usually try to keep their abilities secret.

"Hey, Megumi-chan, do you want to become a magical girl—no, I mean, do you want to become a superpowered individual?" Eriri didn't answer Megumi's question but instead asked with a tone full of temptation.

"Uh..."

Megumi was momentarily stunned. Superpowers—a magical term. As a Japanese high school student in her adolescence, who hasn't fantasized about having a unique special ability?

"So, do you want to or not? Becoming superpowered has lots of benefits! You can gain tremendous strength, maintain eternal youth, and even achieve a long life. It might even boost your presence significantly."

Seeing that Megumi didn't respond right away and stood there in a daze, Eriri assumed she was hesitating to make a decision to surpass humanity. So she began listing the advantages of having superpowers to increase the allure.

"Of course I want to! How could I not? But how do I do it?" Hearing that superpowers could preserve youth, Megumi couldn't resist and eagerly asked Eriri.

"Hehe, it's simple. Didn't I just infuse your body with energy? Try feeling it now; your physical strength already far exceeds that of a regular adult male."

Seeing Megumi's eager expression, Eriri let go of her embrace and stepped back a few steps.

Megumi Kato slowly raised her hands, clenching her fists tightly, and felt the power within them, which was incomparable to her previous self.

"Yoshi!"

Nodding slightly, Megumi seemed to have thought of a way to test her newfound strength. She slowly approached Eriri and, to Eriri's stunned gaze, slipped her hands under Eriri's armpits and lifted her up.

"???"

Something's wrong, Eriri thought, as three large question marks popped up in her mind while she stared expressionlessly at Megumi holding her up.

"Haha... my strength has indeed increased several times over. It's amazing, Eriri! You're incredible. But won't this affect your body since you shared your power with me?"

Feeling Eriri's gaze, Megumi froze slightly and immediately put Eriri down, chuckling to divert her attention.

"Hehe, impressed by my power? Don't worry, this is nothing for me and doesn't affect me at all." Eriri crossed her arms, slightly lifted her head, and said with pride.

"I only boosted your physique a little just now. I'll eventually infuse more energy into you, using it to remodel your body entirely, so you can adapt to and contain the energy. Once that's done, I'll teach you how to use it, and then you'll be a real superpowered individual. But..." Eriri paused.

"But what?" Megumi immediately felt nervous.

"This kind of superpowered individual, made by me, is fundamentally different from typical superpowered people. My powers mainly rely on cosmic energy within me. If that energy runs out, you'll just be someone with a strong physique. That's a significant flaw, but it's easy to fix—you just need to come to me periodically to recharge your energy. You can think of it as mana replenishment..."

Eriri's tone held a hint of helplessness. The cosmic energy entered her body automatically, and while she might eventually control its absorption, she couldn't do so yet, let alone allow Megumi to absorb it herself.

Mentioning mana replenishment made Eriri think of Fate/kaleid liner Prisma Illya, where Kuro replenished her mana through intimate acts like kissing Illya. Eriri could transfer energy this way too, and it would be more effective than using her palm. The thought made her a bit excited.

"I see... but won't that trouble you?" Megumi sighed in relief, having feared it would negatively affect Eriri's body.

"Of course not! I'd love for you to come to me for mana replenishment, hehe..." Eriri laughed mischievously.

"Mana replenishment? What's that? What are you talking about?"

Just then, the duo returned from buying drinks.

"Oh, it's nothing. We were just discussing a TV show we watched yesterday." Startled by Azusa Satomi's voice, Megumi quickly responded, pretending to be calm.

"Oh, really? What show was it? Here, your milk tea." Kiyo Ishimaki, with no suspicion, eagerly joined in the conversation.

Azusa Satomi noticed Megumi's feigned calmness, a hint of doubt in her eyes that soon vanished—she must have misheard.
