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

After Yui had asked the “organization” to dispose of the human corpse, we moved to the rooftop of a nearby building.

「I know you’re not a normal person given how you jump to the roof of the building…I don’t even know where to start…..I don’t even know if Kazu is on our side….」

Yui turns to me with a strong sense of caution, a complete change compared to how we spoke earlier.

That’s completely normal if your childhood friend, who you always thought was normal, suddenly showed unusual power.

How she’s acting is understandable.

「When did you start fighting those kinds of things?」

「…… tonight was my debut battle.」

Yui hesitated for a moment before answering my question.

「Debut battle and you’re alone?」

In the other world, unless there’s a good reason, a battle will always be with a party.

「I’m the only one from the Nordic Organization stationed in japan who can use a divine object.」

I understood a lot from what she just said.

It seems like in this world, there are a number of organizations that fight against such abomination and they do not cooperate with each other.

「What is a divine object? Are you talking about the black tights that you always wear that you used as a weapon?」

「You really don’t know anything….? To be exact, this is a divine object replica.
They are the only weapon that humans can use to compete against them.
They are made of god class “variants”.」

Variant should be the general term for abominations like those dark valkyries.

「They must be precious.」

「There are only a few of them in the world and there are only a few people in the world who can adapt to them.
Talent is often inherited.
A few years ago, I was deemed suitable for it and I’ve been living with this divine object since then.
Today, when my body has gotten used to it, I made my debut.」

「Yui doesn’t need to take such risk.」

「Don’t say that…..when I was 12, they found that I had an aptitude for it and it has become my life’s mission since.」

Yui looked down sadly.

12 years old? I didn’t even notice.

So that’s why we became distant when we were in junior high school.

「Are you doing it to protect me?」

「You, are you really Kazu…..?」

I would never ask such a question given how self-conscious and afraid I was.

However, I once died and experienced hell in a different world.
I know that “time to worry” is a luxury.

「I am Nanba Kazu.
However….」

Should I tell her the truth?

Will she believe it?

And, can I trust Yui…..

「After reincarnating in another world, I returned.
I am that Nanba Kazu.」

I decided to tell her the truth.

I thought she was the one I should trust in this world aside from my little sister.

Though I hid the fact that I lived until my 40s in this world.
