Isekaid 40ish Man Returns, Regressed as a Peerless 17-Year-Old

「Wait, where are you taking me?」

「This should be fine」

As soon as I said that, a divine domain swallowed us.

This was deployed by Futaba, who is hiding behind a prefab shed used as a tool shed.

The divine domain can only be deployed centering on the caster.

It was necessary to find a place where Futaba and the variant could be brought close together while there’s no one else around.

「What!?」

I don’t know what surprised the variant the most.

It could be that she was trapped in a divine domain or it could also be that she was targeted.

Or maybe, she sensed that we still remember her.

However, we were lucky that she showed me an opening at such close range, even for a moment.

I instantly summoned my black sword and cut off the variant’s head.

「E-emergency leap!」

It seems like a time leap is still possible even without the barrier in the gymnasium.

The head and torso are separated from each other.

For a moment, there was a space-time oscillation but that’s it.

-0-

Magic has an affinity strength.

When two or more magic collide, which has priority?

Of course, it also depends on the power of the caster.

According to the results, the divine domain is one of the strongest among all types of magic.

Even a time leap activated outside the domain couldn’t affect the memories or bodies of those who are inside the domain.

And it seems that time travel within the divine domain can’t even be activated.

「What!? This can’t possibly be a divine domain—」

That’s all she could say before she was shredded by my sword.

I also burn the corpse on the ground, leaving no dust behind, just in case.

「Puhaa!」

At the same time as the divine domain was released, a gasping Futaba appeared from the other side of the prefab.

Yui is supporting the wobbly Futaba.

「This is as far as I can go without oniichan’s magic power supply……」

「It is all thanks to you we were able to defeat the variant.」

「Was I that helpful? Hehe……great……」

I send magic power to the smiling Futaba.

「Hnnn…..fu….haa…….feels great…..thanks…..oniichan」

Futaba has managed to recover but is still a little wobbly.

「Alright, I have to get back to the class.」

「Thanks, Yui」

「It’s okay. Our class is almost sold out.」

「This early?」

「So, I think I’ll have a little free time at the end. Would you like to go around the festival with me?」

「Oh, okay. At that time, all the committee members have to do is to direct the public to the exits.」

The team in charge of preparations for the closing ceremony would be busy though.

Incidentally, Usano was sent to the closing ceremony as one of the staff members was out sick.

「Well then, Futaba-chan, take care of Kazu until then.」

「Shiratori-san, that’s something unnecessary to ask.」

「Fufufu…then, see you later!」

Yui said so and ran toward the class.

「What do you want to do, Futaba? Do you want some rest?」

「I’m fine. I’d like to get something to eat.」

「Alright, I’ll buy you anything you like.」

I still have time for my break.

We can at least go around and eat a little.

「Yay!」

It was embarrassing to go around the festival with my little sister’s arm around me.

However, since it makes her happy, it’s not so bad.

I feel bad for Usano though. She even made lunch for me in the previous loop but my priority will always be Yui.
