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

I wonder if I was a little too excited this lunch.

However, it will be allowed at least for today.

Because Kazu is no longer in danger of being killed.

According to the investigation by the “organization”, Kazu is a singularity that easily attracts variants.

He is said to have some kind of channel to other worldly things.

Without him, my little sister wouldn’t have died….

I shake off such thoughts.

With his current power, he would be able to protect himself.

If it’s only a dark valkyrie, I can take care of it but if a greater enemy appeared, I would have to risk my life to defeat it.

That is the kind of ability my divine object has.

The hidden power should be great but I’m incapable of bringing it out….

What I worry about is whether he will be safe after I die.

However, there is no longer a need to worry about it.

That fact alone lightened my heart.

All I have to think about now is to protect the area of my responsibility.

Above all, I’m happy to the fact that I’ll be able to fight with him.

He saved my heart from that house.

We don’t have many chances of seeing each other anymore but from now on, things will be different.

I will deepen my bond with him while fulfilling my mission to protect mankind.

I’m looking forward to it.

Is that inappropriate to say?

I can go work and save mankind with the person I love.

Is it a sin to call this happiness?
