Anime chat group , you let me come only after the world is destroyed?

The earlier versions of the Hourai Elixir were incomplete.

When Kaguya took it, her strength plateaued at a certain level and stopped improving. In essence, it stifled her future potential.

Eirin experienced the same limitation.

They had gained immortality—but lost their path forward.

Because of that, after Kaguya underwent enhancements via the chat group, Eirin took some of her blood samples for further research.

She then improved the original Hourai Elixir, eliminating all side effects.

In theory, with the new version, the longer you lived, the stronger you could become.

Since Takumi needed it, Eirin gave it to him without hesitation.

Takumi accepted the porcelain flask she handed him.

"Good! You two carry on."

With the elixir in hand, he had no desire to interrupt the two mad scientists any further.

"Wait!"

Just as Takumi was about to leave, Eirin stopped him.

He turned, puzzled. "What is it?"

Was there more?

"Please have a child with the princess. I'm very curious what kind of offspring you two would produce."

She was completely serious.

Since Takumi and the princess were already together, she felt it was time for them to have a child.

Mobius's eyes lit up as well.

"That's actually a good idea. I'm curious too. But the stronger the parents, the harder it is to conceive."

"I bet you two don't use any precautions, right? That could be why you haven't had kids."

"If it turns out you really can't have a child, you can come to me. I wouldn't mind helping."

Mobius looked visibly excited.

Right now, what she wanted most was to study Takumi's future child.

She was dying to do research.

But it seemed unlikely. Maybe she thought she should just step in personally?

Hearing her suggestion, Takumi rolled his eyes.

This woman—was she not embarrassed at all saying these things?

Fine, if you're shameless, I'll be shameless too.

"Alright. I'll visit you tonight."

The room fell silent.

Eirin and Mobius both froze.

He was serious?

But Mobius quickly regained her composure, giving Takumi a mischievous grin.

"Sure~! You better remember. If you don't show up, you're a coward."

She wanted to see if he was all talk.

Eirin's eyes gleamed with intrigue.

Goodness, was Mobius trying to trap Takumi?

And if he really did show up—then what?

Takumi was puzzled too. But there was no way he was backing down now.

"Alright, alright. Just wait, future baby mama!"

You want to play? Don't regret it later.

With a scowl, he left the lab.

He had made up his mind. Tonight, he would find out if Mobius's mouth was the only thing she had that was tough.

Let's see how she handled something tougher.

He wasn't going to lose anything by trying.

After Takumi left, Eirin couldn't help but sigh.

"You were serious about this?"

Mobius snorted.

Though she was a little nervous, her words stayed bold.

"I don't think he'll really come. Even if he does, I'm not afraid. Maybe I'll finally get the data I've always wanted."

"I've always wanted to research him. The rest of the Genius Society does too. They're all eager to study Takumi."

Stay calm. Don't panic.

Eirin rolled her eyes.

She understood perfectly. Takumi's very existence was like a drug to researchers—irresistibly fascinating.

Mobius was no exception.

Maybe she was secretly hoping he really would show up.

But Eirin didn't call her out.

...

Takumi returned home, still irritated.

He wasn't in a good mood.

He'd already decided—Mobius was getting what she asked for.

But first, he had other things to take care of.

He found Bronya upstairs, playing video games.

He pulled out the Hourai Elixir he brought back.

Bronya looked at him, puzzled.

"What's that?"

"Hourai Elixir. Take it."

Takumi didn't explain much. He simply handed her a pill.

He had some of the old versions on hand, but he wouldn't give those to Bronya.

That's why he went to get the new formula from Eirin.

Bronya hesitated briefly but didn't ask questions. She quietly took the elixir.

She understood Takumi's intention. There was no need to say anything.

Soon after, she felt the changes in her body.

Some things she thought were gone... had returned?

Feeling the difference, her cheeks turned pink.

"It's really that strong?"

Everything had come back.

Takumi gave her a smug grin. "Impressive, right?"

Bronya tossed her controller aside.

"No more games. Let's go enjoy ourselves!"

"Just like before..."

Takumi's face lit up with a smile.

After a round of nostalgic fun with Bronya, Takumi called Miori Shiba and Liliya back.

He gave them each a dose of the elixir as well.

Gabriel and Esdeath, who was still out fighting in space, would also get theirs later.

Takumi wasn't going to play favorites—everyone would get one.

Except Kaguya. She already had hers.

After all the running around, it was already nighttime.

As evening settled in, Takumi slipped away.

Everyone found this strange.

Bronya quickly asked, "Where are you going?"

Takumi casually replied, "I'm going to teach Mobius a serious lesson. Damn it, she disrespected me!"

With that, he dashed off.

The others were stunned.

He was going to teach Mobius a lesson?

What had happened?

"Prometheus, what's going on? Do you know anything?"

When in doubt, they turned to Prometheus.

But this time, Prometheus remained silent.
