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

「You misunderstood.
This is not summoning, it’s generating.
I created it with my magic power using the data I took during last night’s battle.」

Since it came from the data analyzed during last night’s battle, it won’t be able to do the techniques that I didn’t see at that time.

I put my hand on the dark valkyrie’s shoulder.

The dark valkyrie, who’s arms are slumped down, is staring into the void with dead fish-like eyes.
It shows no reaction.

「That…..it’s impossible to do that unless you’re overwhelmingly stronger than the dark valkyrie, right…..?」

「It’s just an enemy of this caliber though.」

「Well, it’s true that dark valkyries are one of the small fries among nordic variants but, to an ordinary human, its threat is much greater than a lion….」

「Yeah yeah.
For now, try to use your strongest technique.」

「Yeah, I’ll do so.
Gungnir…..activate!」

Yui touches her thighs in black tights from under her mini skirt using two fingers to each side.

Rune letters glowed on the part of the tights she touched and at her ankle, the letters converged forming a frisbee sized magic circle.

「Hnnn…..kwu….areh? It feels okay and it doesn’t hurt much…..? And….」

Yui took a big leap and instantly reached the ceiling, which was probably as high as the second floor of a private house.

Yui flipped and landed dexterously on the ceiling.

Kicking the ceiling, she returned to the floor.

「Gungnir, full power!」

Yui touched her thigh and took a stance on which her weight is on her right leg.

Magic power ran through her entire body.
It increased in purity and concentration and eventually gathered on her right leg.

Yui herself doens’ seem to know much about magic but this is one way of using it.

「Haaaaaaa! Ragnarok Break!!」

Yui delivered a back kick with her dusk colored right foot to the chest of the dark valkyrie.

The impact of the kick passed through the dark valkyrie’s back and a shockwave hit the walls of the dojo.

At that moment, the dark valkyrie’s body cracked with light at the place Yui hit and shattered like a rock.

Yui slowly lowered her right leg and returned to her original stance.
Then, rubbed her shaking leg.

「After using the technique, my whole body will feel heavy for a while and I won’t be able to move my right leg for a few hours….muscle training is amazing….?」

「You became able to withstand the burden of the divine object to some extent.
In addition to that, I also prepared magic circuits in your body in addition to muscle training.」

「Magic circuit?」

「It is the path of the magic power in the body.
That black tights type divine object seems to channel the magic power stored in it to the user making the user’s physical ability surpass normal humans.
The special move you just used forcefully poured magic power kneaded inside the enemy’s body, shredding the enemy’s magic circuit, then used the opponent’s magic power to destroy its body.
It’s a pretty amazing magic tool.」

I wonder how it was made even though magic is not popular here.

Do some people have a monopoly on information?

「You managed to know that much after seeing it?」

「I will be able to analyze it more by touching it.」

When I said that,

「I don’t mind, touch me….」

Yui, blushed a little.
She raised her leg and offered her thigh.
