After returning home from the deserted island, I explained to Futaba the whole process from training the soldiers to defeating Hades.

「I understand what’s going on and I’m not mad at you but……muu……」

Futaba looks obviously dissatisfied.

「I brought a souvenir just for Futaba so forgive me.」

「What, what?」

I gave Futaba the headband I got from the island.

I have already synthesized it with the remnant of the core core.

Synthesizing it consumed the remnant of the core but only a small amount of the core was synthesized into the headband.

It was probably less than half the concentration of gungnir.

「I can’t believe oniichan would prepare a present for me!」

Futaba’s eyes sparkle as she holds up the black headband.

「It’s a divine object given to me by the soldiers. Check if you can use it.」

「Divine….ah…..okay」

Why do you look so disappointed?

「I thought it would be better if Futaba also had a way to protect yourself other than the divine domain. I heard that no one has ever adapted to it. I don’t know what the effect is.」

Even more so because I synthesized it.

「Okay……you’re worried about me. Thanks.」

Futaba was a little disappointed but still put the headband on her head.

So, why do you look a little disappointed?

「Just putting it on doesn’t make anything happen……」

Futaba touched it with her finger but there was no response.

「I’ve heard that when you touch a divine object that you have aptitude on, you’ll feel something. Do you feel anything?」

「Yeah…..I can’t help but think this  is just a headband. I can feel magic power when I concentrate on it but it’s the same as when I look at any other divine object.」

「I see……」

I thought that Futaba, who has Susanoo’s blood, might have a greater aptitude for divine objects but I guess that was not the case.

「Hey, oniichan. Can I have this?」

「I don’t have anyone else I can give it to. It’s yours.」

「Great, thanks!」

Is she in a good mood or a bad mood?

That said, at least she likes it.

「It looks good on you.」

「Eh……」

Futaba’s face turned a little red when I casually said those words.

「Even if we’re siblings, don’t just say things like that.」

If you’re that embarrassed, it makes me feel embarrassed too.

It’s a different kind of embarrassment that I feel when I’m with Yui. This is the kind of embarrassment one feels for your family.

「You’re thinking of another woman」

「No, I’m not」

「Muu~. Well, okay. However, you didn’t forget your promise that you’ll take me out to play, right?」

「Of course」

「Then, first of all, you need to help me buy some clothes! Let’s go tomorrow!」

「Are you saying it’s only a preparatory battle!?」

「Come to think of it, even if oniichan’s phone doesn’t work, you can always get here from the deserted island anytime.」

「Ahh…..」

「To think you will leave your little sister alone and had fun with your big breasted childhood friend……」

「Argh…..」

「You okay?」

「Of course」

It looks like I’m going to pay for those clothes.
