「How’s the school festival committee going?」
Yui asked lazily as she reamed the dark valkyrie’s head with her supple legs.
It was late at night in a valley of buildings.
Finding a couple of dark Valkyries, I’m already completely used to it.
「It’s surprising to see oniichan as a member of a committee.」
Futaba, who said that, is maintaining the “divine domain” by receiving magic power supply from me.
The downtown area, still crowded with people, is so quiet that the sound of clothing rustling can be heard.
The divine domain also blocks sound.
「I didn’t became a member because I wanted to.」
While each committee member was chosen at the beginning of the school year, those who did not run for the committee were chosen by draw lots.
In essence, a member of the school festival committee is in charge of miscellaneous work.
Since they are required to spend a considerable amount of time on the day of the festival as well, those who are looking for a date for the festival avoid it.
Although it is a popular position among some motivated people, there was no one like that in our class.
Watanabe, who seems to want to do it the most, is a class committee member.
「The teachers do most of the ordering for the vendors. I don’t do much.」
「I heard rumors that you are working very hard. I’m worried about you collapsing at night when we have to take down variants.」
Yui came back to my side after sending magic power into the variant’s corpse and tearing it to pieces.
「It’s no big deal.」
It’s like a holiday compared to the hard work I did during my black company days and in the other world.
「Let me know if there’s anything I can do to help.」
「I will」
「Mou…..That high school festival. I’m definitely going to go.」
I don’t think it’s interesting to see another school’s school festival but I won’t bother to stop my little sister from coming.
「That aside…..ah….mou……don’t……」
I felt a slight resistance when I was pouring magic power into Futaba.
It was as if the water hose had almost clogged up.
「This is as far as we go.」
While using the 20 meter cubic divine domain, even if I continue to supply magic power to her, Futaba can only endure for about 10 minutes.
In practice, it can be a little longer but in actual battle, her internal magic circuits are disrupted probably due to nervousness making the time a little shorter.
It is gradually getting longer and the only way to do it is to do this more often.
「Hnnn………haa…haa……」
Futaba gasped for her breath and slumped down as her body jerks and twitches.
It looks erotic when Yui’s being like this but I feel very awkward seeing my little sister like this.
Being supplied with magic power is both painful and pleasurable at the same time.
There was nothing we could do but to wait for it to subside.

As soon as the divine domain was lifted, the windowpanes and concrete that had been destroyed by Yui’s attack were restored.
This ability is really useful.
Come to think of it, what happens if you shove something in the place to be restored?
Does it get pushed out?
I don’t think it will be synthesized.
I’ll give it a try next time.
「Can you stand up, Futaba?」
「Mou….mouuuuuu….」
Futaba, whose face is red, leaned on me.
When did you start looking so sexy?
This girl is a junior high school student and my little sister, junior high school student and my little sister……..
-0-
I carried Futaba on my back and leaped to the roof of a building.
And Yui followed me.
「Mou……hey, Kazu. My training frequency is a little low these days, isn’t it?」
Next to me jumping in the night sky, Yui’s lips twitched in frustration.
「First of all, we need to train Futaba to some extent. At least enough for her to survive.」
Futaba’s ability is amazing but she lacks offensive methods.
First of all, she needs to be able to use the divine domain while attacking and defending.
「Ugh…….when you put it that way…」
「I’ll give Yui plenty of training once she settles down.」
「Alright!」
Seeing her smiling happily makes me want to work even harder.
