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

I had left their residence in accordance to Yui’s request that I should escape without hesitation if I was about to be discovered by the Shiratori family but I’m so anxious that I can’t help but give her a call.

Apparently, Yui had defeated a variant that had come to the premises and the matter was settled.

Of course, Thor’s presence was concealed and the dojo was blown up because it self-destructed.

The security camera footage was also well concealed as we planned in advance.

Although the case passed like that this time, it is possible that some suspicion has already been raised and an investigation might have already begun.

It would be a good idea to discuss with Yui how we’re going to proceed in the event that we get in contact with the Shiratori family.

The day after Thor’s defeat, Kakogawa and the health committee member did not come to school.

A day’s absence would not cause a fuss.

However, the girls, who usually made a fuss about who was going to visit Kakogawa, were quiet.

Perhaps they are already beginning to forget them.

I also wonder what is going on at their homes but I can’t do anything about it….

He was a jerk but my heart aches a little when I think of the family he left behind.

It’s a relief that the family’s grief won’t last long.

According to Yui, those who fight against human eating variants tend to retain memories of those people who were eaten.

She says that this is because it creates a connection with the law of causality.

But eventually, this memory will disappear.

Wait a minute, what about in my previous life?

During my corporate slave time, I would occasionally think back my high school days.

At that time, did that health committee member ever cross my mind?

Though I remembered there’s a girl I didn’t like.

Is me regressing changed the people who died?

I supposed I shouldn’t be happy about the deaths of others but this fact shows that the future will change.

There was a concern that in a world that is bound with the law of causality, fate could not be changed.

However, one’s life and death can be changed.

In other words, there is a way for Yui to be saved.

Then, that makes all things simple.

If I’m here, I can save Yui.

Of course, I don’t want her to only live but to lead a life where she can always be happy.

However, deciding to save someone close to you means giving up on saving everyone else in the world.

I know well that saving the world leads to giving up those who are important to me.

I saved the world once.

Then, this time, allow me to live selfishly.
